Cowgirl - MIPS R3000 Resemblance in VHDL

This is an implementation of an instruction set that I created. It's not a particularly useful thing to do, but it's something I've always been interested in. The instruction set bears a strong resemblance to the MIPS R3000, but this wasn't exactly deliberate. It's really the only instruction set I've been heavily exposed to. I'm keeping design documents and software I've written for this project on my website if anybody's interested. There's also a copy of the source and the modelsim project that I use, but it will most likely be updated less than the cvs version here.
