65 merging in some docs to zpu_arch.html oharboe 5788d 00h /
64 wip oharboe 5791d 05h /
63 very early work. oharboe 5791d 09h /
62 * duplicated crt0.s and some other stuff from libgloss into
sw/startup. This makes it easier to tinker w/startup code.		 oharboe 5791d 09h /
61 wip oharboe 5791d 14h /
60 wip oharboe 5793d 13h /
59 pdf versions oharboe 5794d 01h /
58 some more docs. oharboe 5794d 01h /
57 a few words about zpu_core.vhd and zpu_core_small.vhd oharboe 5794d 01h /
56 added FreeBSD license. Finally. oharboe 5794d 01h /
55 tips for rolling your own ZPU oharboe 5794d 01h /
54 some ideas. oharboe 5794d 02h /
53 marked unused instruction opcodes as OpCode_NAx oharboe 5794d 10h /
52 deleted reference to ic300 dating back to ZY2000 implementation. oharboe 5797d 08h /

* zpu/hdl/zpu4/core/histogram.perl - generate opcode histogram from
HDL simulation output		 oharboe 5801d 09h /
50 link to zpu_arch.html oharboe 5801d 09h /
49 added link. oharboe 5801d 09h /
48 add missing defs. oharboe 5802d 08h /
47 added basic docs on emulated instructions. oharboe 5802d 10h /
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 5845d 15h /
45 * zpu_config.vhd: Fixed startSp calculation (address in bytes not words) oharboe 5852d 02h /
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 5852d 03h /
43 take 2 oharboe 5852d 04h /
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 5852d 04h /
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 5852d 12h /
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 5852d 23h /
39 Linux ZPU GCC toolchain oharboe 5892d 15h /
38 Mike Frysinger found this file which is not needed. oharboe 5893d 14h /
37 wip from jurij.kostasenko oharboe 5893d 15h /
36 * Small ZPU now supports interrupts
* added simulation example demonstrating interrupts		 oharboe 5895d 15h /
