-<h2>JTAG/hardware debugger for GDB</h2>

-The Zylin <a href="http://www.zylin.com/zy1000.html">ZY1000</a> JTAG debugger supports

-the ZPU. Contact <a href="http://www.zylin.com">Zylin</a> for pricing and details.

-<p>

-There are two debug modes in which the ZY1000 can operate:

-<ul>

-<li>Classic. Here the ZY1000 controls the CPU and examines the state. The ZY1000 has a built in

-GDB server that GDB talks to.

-<li>Small footprint. If there isn't enough space on the device for the ZPU *and* the JTAG

-controller, then the ZY1000 can run the ZPU externally. The JTAG communication channel is

-then used to peek/poke peripherals and inside the FPGA instead of the ZPU there is then

-a JTAG controller that peeks and pokes the peripherals of the ZPU. There are advantages

-and disadvantages of this approach: it may be unfamiliar to embedded developers and  

-the timing is different from the "real" ZPU(interrupts are delayed, execution speed

-differse, etc.) On the other hand there are other things

-which are simpler: much more RAM can be available for the ZPU during development,

-better debug consoles(faster), additional peripheral(timers, etc.) is available. This

-approach is somewhat unique to the ZPU as the ZPU is simple enough that it can be

-implemented efficiently in this manner.

 <h2>Speeding up the ZPU</h2>

 There are two aspects of speeding up the ZPU: making it perform better
