+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+A. DESCRIPTION
+--------------
+The Jam STAPL Byte-Code Player is a software driver that allows test and programming algorithms
+for IEEE 1149.1 Joint Test Action Group (JTAG)-compliant devices to be asserted via the
+JTAG port. The Jam STAPL Byte-Code Player reads and decodes information in Jam STAPL
+Byte-Code Files (.jbc) to program and test programmable logic devices (PLDs), memories,
+and other devices in a JTAG chain. The Jam STAPL Byte-Code Player complies with STAPL
+(Standard Test and Programming Language) Specification JESD-71. The construction of the
+Player permits fast programming times, small programming files, and easy in-field upgrades.
+Upgrades are simplified, because all programming/test algorithms and data are confined to the
+Jam STAPL Byte-Code File. Version 2.2 supports Jam STAPL Byte-Code Files (.jbc) that have been
+compiled using the Jam STAPL Byte-Code Compiler. The Player is also able to read and "play"
+older Jam Byte-Code files based on Jam v1.1 syntax.
+ The .jbc File is a binary version of the ASCII Jam File (.jam). The Jam STAPL Byte-Code
+format consists, among other things, of a "byte code" representation of Jam commands, as
+they are defined in STAPL Specification JESD-71. This means that the .jbc File is simply a
+different implementation of the .jam file. This binary implementation results in smaller
+file sizes and shorter programming times.
+ This document should be used together with AN 122 (Using STAPL for ISP & ICR via
+an Embedded Processor).

+
+E. PORTING THE JAM STAPL BYTE-CODE PLAYER
+-----------------------------------------
+The Jam STAPL Byte-Code Player is designed to be easily ported to any processor-based hardware
+system. All platform-specific code is placed in the jbistub.c and jbimain.c files. Routines
+that perform any interaction with the outside world are confined to the jbistub.c source
+file. Preprocessor statements encase operating system-specific code and code pertaining to
+specific hardware. All changes to the source code for porting are mostly confined to the
+jbistub.c file and in some cases porting the Jam Player is as simple as changing a
+single #define statement. This process also makes debugging simple. For example, if
+the jbistub.c file has been customized for a particular embedded application, but is
+not working, the equivalent DOS Jam STAPL Byte-Code Player and a download cable can be used to
+check the hardware continuity and provide a "known good" starting point from which to attack
+the problem.
+
+The jbistub.c and jbimain.c files in this release target the DOS operating system, by default.
+To change the targeted platform, edit the following line in the jbistub.c and jbimain.c files:
+
+ #define PORT DOS
+
+The preprocessor statement takes the form:
+
+ #define PORT [PLATFORM]
+
+Change the [PLATFORM] field to one of the supported platforms: EMBEDDED, DOS, WINDOWS,
+or UNIX. The following table explains how to port the Jam STAPL Byte-Code Player for each of the
+supported platforms:
+
+PLATFORM COMPILER ACTIONS
+-------- -------- ---------------------------------------------
+EMBEDDED 16 or 32-bit Change #define and see EMBEDDED PLATFORM below
+DOS 16-bit Change #define and compile
+WINDOWS 32-bit Change #define and compile
+UNIX 32-bit Change #define and compile
+
+The source code supplied in this release is ANSI C source. In cases where a different
+download cable or other hardware is used, the DOS, WINDOWS, and UNIX platforms will require
+additional code customization, which is described below.
+
+EMBEDDED PLATFORM
+Because there are many different kinds of embedded systems, each with different hardware and
+software requirements, some additional customization must be done to port the Jam STAPL
+Byte-Code Player for embedded systems. To port the Player, the following functions may
+need to be customized:
+
+FUNCTION DESCRIPTION
+--------- ------------------------------------------------------------------
+jbi_jtag_io() Interface to the IEEE 1149.1 JTAG signals, TDI, TMS, TCK, and TDO.
+jbi_message() Prints information and error text to standard output, when available.
+jbi_export() Passes information such as the User Electronic Signature (UES) back to the
+ calling program.
+jbi_delay() Implements the programming pulses or delays needed during execution.
+
+Miscellaneous
+jbi_vector_map() Processes signal-to-pin map for non-IEEE 1149.1 JTAG signals.
+jbi_vector_io() Asserts non-IEEE 1149.1 JTAG signals as defined in the VECTOR MAP.
+
+jbi_jtag_io()
+-------------
+int jbi_jtag_io(int tms, int tdi, int read_tdo)
+
+This function provides exclusive access to the IEEE 1149.1 JTAG signals. You must always
+customize this function to write to the proper hardware port.
+
+The code in this release supports a serial mode specific to the Altera BitBlaster download
+cable. If a serial interface is required, this code can be customized for that purpose.
+However, this customization would require some additional processing external to the
+embedded processor to turn the serial data stream into valid JTAG vectors. This readme file
+does not discuss customization of serial mode. Contact Altera Applications at (800) 800-EPLD
+for more information.
+
+In most cases a parallel byte mode is used. When in byte mode, jbi_jtag_io() is passed
+the values of TMS and TDI. Likewise, the variable read_tdo tells the function whether
+reading TDO is required. (Because TCK is a clock and is always written, it is written
+implicitly within the function.) If requested, jbi_jtag_io() returns the value of TDO read.
+Sample code is shown below:
+
+int jbi_jtag_io(int tms, int tdi, int read_tdo)
+{
+ int data = 0;
+ int tdo = 0;
+
+ if (!jtag_hardware_initialized)
+ {
+ initialize_jtag_hardware();
+ jtag_hardware_initialized = TRUE;
+ }
+
+ data = ((tdi ? 0x40 : 0) | (tms ? 0x02 : 0));
+
+ write_byteblaster(0, data);
+
+ if (read_tdo)
+ {
+ tdo = (read_byteblaster(1) & 0x80) ? 0 : 1;
+ }
+
+ write_byteblaster(0, data | 0x01);
+
+ write_byteblaster(0, data);
+
+ return (tdo);
+}
+
+The code, as shown above, is configured to read/write to a PC parallel port.
+initialize_jtag_hardware() sets the control register of the port for byte mode. As shown
+above, jbi_jtag_io() reads and writes to the port as follows:
+
+|---------------------------------------------------------------|
+| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | I/O Port
+|---------------------------------------------------------------|
+| 0 | TDI | 0 | 0 | 0 | 0 | TMS | TCK | OUTPUT DATA - Base Address
+|---------------------------------------------------------------|
+| !TDO | X | X | X | X | --- | --- | --- | INPUT DATA - Base Address + 1
+|---------------------------------------------------------------|
+
+The PC parallel port inverts the actual value of TDO. Thus, jbi_jtag_io() inverts
+it again to retrieve the original data. Inverted:
+
+ tdo = (read_byteblaster(1) & 0x80) ? 0 : 1;
+
+If the target processor does not invert TDO, the code should look like:
+
+ tdo = (read_byteblaster(1) & 0x80) ? 1 : 0;
+
+To map the signals to the correct addresses simply use the left shift (<<) or right shift
+(>>) operators. For example, if TMS and TDI are at ports 2 and 3, respectively, then the
+code would be as shown below:
+
+ data = (((tdi ? 0x40 : 0)>>3) | ((tms ? 0x02 : 0)<<1));
+
+The same process applies to TCK and TDO.
+
+read_byteblaster() and write_byteblaster() use the inp() and outp() <conio.h> functions,
+respectively, to read and write to the port. If these functions are not available,
+equivalent functions should be substituted.
+
+jbi_message()
+--------------
+void jam_message(char *message_text)
+
+When the Jam STAPL Byte-Code Player encounters a PRINT command within the .jbc File, it processes
+the message text and passes it to jbi_message(). The text is sent to stdio. If a standard
+output device is not available, jbi_message() does nothing and returns. The Jam STAPL
+Byte-Code Player does not append a newline character to the end of the text message.
+This function should append a newline character for those systems that require one.
+
+jbi_export()
+------------
+void jbi_export(char *key, long value)
+
+The jbi_export() function sends information to the calling program in the form of a text
+string and associated integer value. The text string is called the key string and it
+determines the significance and interpretation of the integer value. An example use of this
+function would be to report the device USERCODE back to the calling program.
+
+jbi_delay()
+-----------
+void jbi_delay(long microseconds)
+
+jbi_delay() is used to implement programming pulse widths necessary for programming PLDs,
+memories, and configuring SRAM-based devices. These delays are implemented using software
+loops calibrated to the speed of the targeted embedded processor. The Jam STAPL Byte-Code
+Player is told how long to delay with the .jbc File WAIT command. This function can be
+customized easily to measure the passage of time via a hardware-based timer. jbi_delay()
+must perform accurately over the range of one millisecond to one second. The function can
+take as much as 10% more time than is specified, but cannot return in less time. To minimize
+the time to execute the Jam statements, it is generally recommended to calibrate the delay as
+accurately as possible.
+
+Miscellaneous Functions
+------------------------
+jbi_vector_map() and jbi_vector_io()
+
+The VMAP and VECTOR Jam commands are translated by these functions to assert signals to
+non-JTAG ports. Altera .jbc Files do not use these commands. If the Jam STAPL Byte-Code Player
+will be used only to program Altera devices, these routines can be removed. In the event
+that the Jam Player does encounter the VMAP and VECTOR commands, it will process the
+information so that non-JTAG signals can be written and read as defined by JEDEC Specification
+JESD-71.
+
+jbi_malloc()
+
+void *jam_malloc(unsigned int size)
+
+During execution, the Jam STAPL Byte-Code Player will allocate memory to perform its tasks. When
+it allocates memory, it calls the jbi_malloc() function. If malloc() is not available to the
+embedded system it must be replaced with an equivalent function.
+
+jbi_free()
+
+void jbi_free(void *ptr)
+
+This function is called when the Jam STAPL Byte-Code Player frees memory. If free() is not
+available to the embedded system, it must be replaced with an equivalent function.
+
+F. JAM STAPL Byte-Code Player API
+---------------------------------
+The main entry point for the Jam Player is the jbi_execute function:
+
+JAM_RETURN_TYPE jbi_execute
+(
+ PROGRAM_PTR program,
+ long program_size,
+ char *workspace,
+ long workspace_size,
+ char *action,
+ char **init_list,
+ long *error_line,
+ int *exit_code,
+ int *format_version
+)
+
+This routine recieves 6 parameters, passes back 2 parameters, and returns a status
+code (of JAM_RETURN_TYPE). This function is called once in main(), which is coded in the
+jbistub.c file (jbi_execute() is defined in the jbimain.c file). Some processing is done in
+main() to check for valid data being passed to jbi_execute(), and to set up some of the
+buffering required to store the .jbc File.
+
+The program parameter is a pointer to the memory location where the .jbc File is stored
+(memory space previously malloc'd and assigned in main()). jbi_execute() assigns this
+pointer to the global variable jbi_program, which provides the rest of the Jam STAPL
+Byte-Code Player with access to the .jbc File via the GET_BYTE, GET_WORD, and
+GET_DWORD macros.
+
+program_size provides the number of bytes stored in the memory buffer occupied
+by the .jbc File.
+
+workspace points to memory previously allocated in main(). This space is the sum of all
+memory reserved for all of the processing that the Jam STAPL Byte-Code Player must do, including
+the space taken by the .jbc File. Memory is only used in this way when the Jam STAPL Byte-Code
+Player is executed using the -m console option. If the -m option is not used, the Jam Byte
+Code Player is free to allocate memory dynamically as it is needed. In this case, workspace
+points to NULL. jbi_execute() assigns the workspace pointer to the global variable,
+jbi_workspace, giving the rest of the Jam STAPL Byte-Code Player access to this block of memory.
+
+workspace_size provides the size of the workspace in bytes. If the workspace pointer points
+to NULL this parameter is ignored. jbi_execute() assigns workspace_size to the global
+variable, jbi_workspace_size.
+
+action is the way the Player is told what function should be performed, as defined
+by STAPL. (i.e. PROGRAM, READ_USERCODE, etc) The action pointer points to the string
+that tells the Player what functions to execute within the .jbc file. Each action can
+contain "recommended" and "optional" sub-actions. "Recommended" sub-actions are those
+that will be executed by default, while "optional" sub-actions will be skipped.
+For example, passing "PROGRAM\0" will result in the following steps for an Altera .jbc
+file:
+ - ERASE (recommended)
+ - BLANKCHECK (optional)
+ - PROGRAM (recommended)
+ - VERIFY (recommended)
+
+So, by simply passing "PROGRAM\0" the device will be programmed and verified. This is the
+action Altera recommends using with it's .jbc files. If you want to add the BLANKCHECK step
+you must pass "DO_BLANKCHECK=1\0" via the init_list pointer. See Section D for other valid
+action strings. Note that the action string must be NULL terminated.
+
+init_list is a parameter that is used when applying pre-JEDEC, Jam v1.1 .jbc files, or when
+overriding optional sub-actions, as in the example above. While older pre-JEDEC .jbc files
+can be played, it is strongly recommended that STAPL-based .jbc files be used. When using
+STAPL-based .jbc files, init_list should point to NULL. If an older .jbc file must be used,
+see AN 88 for more details on the parameters that init_list can point to.
+
+If an error occurs during execution of the .jbc File, error_line provides the
+line number of the .jbc File where the error occured. This error is associated
+with the function of the device, as opposed to a syntax or software error in the .jbc File.
+
+exit_code provides general information about the nature of an error associated with a
+malfunction of the device or a functional error:
+
+ exit_code Description
+ --------- -----------
+ 0 Success
+ 1 Checking chain failure
+ 2 Reading IDCODE failure
+ 3 Reading USERCODE failure
+ 4 Reading UESCODE failure
+ 5 Entering ISP failure
+ 6 Unrecognized device
+ 7 Device version is not supported
+ 8 Erase failure
+ 9 Device is not blank
+ 10 Device programming failure
+ 11 Device verify failure
+ 12 Read failure
+ 13 Calculating checksum failure
+ 14 Setting security bit failure
+ 15 Querying security bit failure
+ 16 Exiting ISP failure
+ 17 Performing system test failure
+
+These codes are intended to provide general information about the nature of the failure.
+Additional analysis would need to be done to determine the root cause of any one of these
+errors. In most cases, if there is any device-related problem or hardware continuity
+problem, the "Unrecognized device" error will be issued. In this case, first take the
+steps outlined in Section D for debugging the Jam Player. If debugging is unsuccessful,
+contact Altera for support.
+
+If the "Device version is not supported" error is issued, it is most likely due to a
+.jbc File that is older than the current device revision. Always use the latest version of
+MAX+PLUS II to generate the .jbc File. For more support, see Section G.
+
+jbi_execute() returns with a code indicating the success or failure of the execution. This
+code is confined to errors associated with the syntax and structural accuracy of the .jbc
+File. These codes are defined in the jbistub.c file, where the array variable "error_text[]".
+
+format_version should be set equal to "2" when calling jbi_execute. This means that the
+Player will expect a STAPL-based .jbc file.
+

+Memory usage is documented in detail in AN 122 (Using the Jam Language for ISP via an
+Embedded Processor).
