2008-11-12 Álvaro Lopes * zpu/hdl/zpu4/core/zpu_core.vhd: Basic interrupt implementation for zpu4 core. 2008-09-16 Salvador Eduardo Tropea * zpu/hdl/zealot: added small ZPU core, testbenches and FPGA implementation 2008-09-11 Salvador Eduardo Tropea * zpu/docs/zpu_arch.html: added Zealot information. 2008-09-08 Salvador Eduardo Tropea * zpu/hdl/zealot: a complete ZPU implementation cleaned up and with a UART. 2008-08-25 Salvador Eduardo Tropea * zpu/docs/arch_html: Fix typo in zpu_arch.html w.r.t. ZPU UART/Debug channel 2008-08-18 Øyvind Harboe * duplicated crt0.s and some other stuff from libgloss into sw/startup. This makes it easier to tinker w/startup code. 2008-08-08 Salvador E. Tropea * zpu/hdl/zpu4/core/histogram.perl - generate opcode histogram from HDL simulation output 2008-06-25 Øyvind Harboe * do not enable interrupts for simzpu_small.do. hello world does not have an interrupt handler, so this caused a BREAK instruction to be executed. 2008-06-18 Miguel Freitas * zpu_config.vhd: Fixed startSp calculation (address in bytes not words) 2008-06-18 Miguel Freitas * Removed unisim/roc dependency (it was used just to pulse the areset) and fixes paths for building the ghdl examples out of the box. One should check if the areset change doesn't break modelsim. 2008-06-16 Miguel Freitas * io.vhd: fix address comparsion and added numerous outputs during simulation to make things a bit easier * zpu_config.vhd: do not use hardcoded startSp, allows more easily tinkering w/RAM size 2008-05-06 Øyvind Harboe * Small ZPU now supports interrupts * added simulation example demonstrating interrupts 2008-05-05 Øyvind Harboe * added eCos HAL for ZPU zpu/zpu/sw/ecos/repository 2008-05-04 Øyvind Harboe * moved ZPU core files to seperate folder * deleted some obsolete files 2008-05-04 jurij kostasenko * Make code synthesize on Synopsis zpu/hdl/zpu4/src/zpu_core_small.vhd zpu/hdl/zpu4/src/io.vhd 2008-05-01 Øyvind Harboe * zpu/hdl/zy2000 - ZPU implementation used on the zy2000 dev kit 2008-04-17 Arnim Läuger * zpu/hdl/example_ghdl/ghdl_import.sh, zpu/hdl/example_ghdl/ghdl_make.sh, zpu/hdl/example_ghdl/ghdl_options.sh, zpu/hdl/example_ghdl/README: GHDL example * zpu/hdl/zpu4/src/dmipssmalltrace_ghdl.sh: testcase for GHDL * zpu/hdl/zpu4/src/dmipstrace_ghdl.sh: testcase for GHDL * zpu/hdl/zpu4/src/simzpu_medium_ghdl.sh: testcase for GHDL * zpu/hdl/example/helloworld.vhd, zpu/hdl/zpu4/src/bram_dmips.vhd, zpu/hdl/zpu4/src/dmipssmalltrace_ghdl.sh, zpu/hdl/zpu4/src/dram_dmips.vhd, zpu/hdl/zpu4/src/dram_hello.vhd, zpu/hdl/zpu4/src/io.vhd, zpu/hdl/zpu4/src/sim_fpga_top.vhd, zpu/hdl/zpu4/src/sim_small_fpga_top.vhd, zpu/hdl/zpu4/src/timer.vhd, zpu/hdl/zpu4/src/trace.vhd, zpu/hdl/zpu4/src/zpu_config_trace.vhd, zpu/hdl/zpu4/src/zpu_core_small.vhd, zpu/hdl/zpu4/src/zpu_core.vhd, zpu/hdl/zpu4/src/zpupkg.vhd: conversion to numeric_std 2008-04-17 Øyvind Harboe * deleted duplicate files from example folder. * retired Xilinx synthesizing example. It messes up the zpu4 directory. 2008-04-16 Øyvind Harboe * zpu/doc/zpupresentation_old.odt: interesting bits moved into zpu_arch.html * zpu/doc/zpupresentation.*: interesting bits moved into zpu_arch.html * zpu/docs/zpu_arch.html: added Phi memory map to end of zpu_arch.html * zpu/docs/zpuphiregs.odt: retired * zpu/docs/zpu_arch.html: added. Need to define instruction set. * zpu/docs/zpu_arch.odt: retired 2008-04-15 Øyvind Harboe * zpu/docs/zpu_arch.odt - a short summary of the architecture * zpu/simzpu_bram.do - retired. * zpu/zpu_core_bram.vhd - retired * zpu/hdl/zpu3 - retired 2008-04-05 Øyvind Harboe * zpu/docs/zpuphiregs.odt - ZPU Phi register overview 2008-03-06 Adam Pierce * zpu/zpu/hdl/example/zpuromgen.c - generate rom files without java 2008-02-21 Øyvind Harboe * zpu/zpu/sw/index.html. Changed it a bit to make installation easier. * zpu/zpu/hdl/index.html. Sharpened instructions and shows two working examples. Small & medium ZPU. * got zpu4/src/simzpu_medium.do working again. 2008-02-11 Øyvind Harboe * hdl/index.html. Fixed typo. Use objcopy and not objdump. 2008-01-02 Øyvind Harboe * Moved to www.opencores.org
