57 Some bug fixes to the dhrystone benchmark, and some compile time defines for
the test bench processor. Of the most important note is the fix to detect
lockups on the debug/wishbone bus--that has been a real help in getting the
ZipCPU installed and the debugger working on the various boards I'm working
with. (i.e., it's helped me find and figure out why/when things haven't worked)
Of other note is the new 'G' key in the testbench code, to cause the test
bench to run without user interaction until the next keystroke. This is
very valuable in long programs, as it makes getting to/from breakpoints
easier (i.e. you don't have to wait as long, hit 'G', breathe, hit 'space'
and you're there).

50 Dhrystone benchmark updates--added the copyright notice. (Oops!) dgisselq 2555d 14h /zipcpu/trunk/bench/asm/
42 Oops -- forgot to add the stack. dgisselq 2555d 14h /zipcpu/trunk/bench/asm/
41 Assembly file for the Dhrystone benchmark added. dgisselq 2555d 14h /zipcpu/trunk/bench/asm/
40 Quick update, updates the assembly for the new version of the assembler. dgisselq 2555d 14h /zipcpu/trunk/bench/asm/
36 *Lots* of changes to increase processing speed and remove pipeline stalls.

Removed the useless flash cache, replacing it with a proper DMA controller.

"make test" in the main directory now runs a test program in Verilator and
reports on the results.

12 Bunch of changes while trying to get a hello world program:
1. Right shifts by 32 or more now result in zero, or all of the top bit in the
case of ASRs.
2. zdump now properly includes addresses with dumped lines.
3. zparser now properly handles immediate values via the .DAT instruction.

11 This version works on an FPGA!!!

(Or at least the wdt.S program passes ...)

10 Here's the watchdog timer code, as well as some pictures of the register

2 An initial load. No promises of what works or not, but this is where the
project is at.
