64 wip oharboe 5775d 18h /
63 very early work. oharboe 5775d 22h /
62 * duplicated crt0.s and some other stuff from libgloss into
sw/startup. This makes it easier to tinker w/startup code.		 oharboe 5775d 23h /
61 wip oharboe 5776d 03h /
60 wip oharboe 5778d 02h /
59 pdf versions oharboe 5778d 14h /
58 some more docs. oharboe 5778d 14h /
57 a few words about zpu_core.vhd and zpu_core_small.vhd oharboe 5778d 14h /
56 added FreeBSD license. Finally. oharboe 5778d 14h /
55 tips for rolling your own ZPU oharboe 5778d 14h /
54 some ideas. oharboe 5778d 16h /
53 marked unused instruction opcodes as OpCode_NAx oharboe 5779d 00h /
52 deleted reference to ic300 dating back to ZY2000 implementation. oharboe 5781d 21h /

* zpu/hdl/zpu4/core/histogram.perl - generate opcode histogram from
HDL simulation output		 oharboe 5785d 22h /
50 link to zpu_arch.html oharboe 5785d 22h /
49 added link. oharboe 5785d 23h /
48 add missing defs. oharboe 5786d 21h /
47 added basic docs on emulated instructions. oharboe 5786d 23h /
46 * 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.		 oharboe 5830d 04h /
45 * zpu_config.vhd: Fixed startSp calculation (address in bytes not words) oharboe 5836d 15h /
44 Miguel Freitas <mfreitas@gmail.com>
log.txt and trace.txt currently on cvs were produced by interrupt.vhd.
this patch will build example_ghdl with interrupt.vhd by default so
user can compare results. adds a note about what user needs to edit to
simulate helloworld.vhd without interrupts.		 oharboe 5836d 16h /
43 take 2 oharboe 5836d 17h /
42 I'm also attaching another patch which removes unisim/roc dependency
(it was used just to pulse the areset) and fixes paths for building
the ghdl examples out of the box. I guess this is the easiest way to
get zpu running on linux with minimum effort.

You should check if the areset change doesn't break modelsim. It feels
much simpler this way and seems to work the same, i might be missing
something.		 oharboe 5836d 17h /
41 * Various ZY2000 vhdl files of more general interest made
available as part of the ZPU project under the same
license(FreeBSD). Files should have headers updated.		 oharboe 5837d 01h /
40 * 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		 oharboe 5837d 12h /
39 Linux ZPU GCC toolchain oharboe 5877d 04h /
38 Mike Frysinger found this file which is not needed. oharboe 5878d 03h /
37 wip from jurij.kostasenko oharboe 5878d 04h /
36 * Small ZPU now supports interrupts
* added simulation example demonstrating interrupts		 oharboe 5880d 04h /
35 forgot to commit log message. oharboe 5880d 05h /
