A Tiny Computer

Lambda the Ultimate today posted a interesting blog entry on A Tiny Computer. It refers to 2007 paper by Chuck Thacker at Microsoft Research describing a tiny 32-bit processor. Appendix A of the paper includes the entire synthesizeable verilog implementation in just a page and a half of code! Here's a direct link to the PDF:

I plan on using verilog for my initial moxie implementation. I'm told that it's the clear choice from a tools perspective. There's even a free software implementation already packaged for Fedora: Icarus Verilog. As far as eduction is concerned, I've mainly been using the two terrific books show below. Do you have any better suggestions? I'd love to hear them.

Now, however, I'm still debugging GDB's interaction with qemu. It mostly involves watching remote protocol traffic, looking up the packet codes, and then trying to understand why the simulator is not behaving as expected. Good times...
