» 4stack Processor
   Research project for high performance, low cost computing. Uses stack-based instructions for a 4-way VLIW processor. Implemented in current technology, it would outrun high-end DSPs (TMS 320C6x, TigerSHARC), and let the full program run on one processor,

» E25 Computer Architecture: Lab 5: OISC: One Instruction Set Computer
   Class project to design and implement One Instruction Set Computer; using instruction: SUBLEQ A B C. Meaning: subtract value in M(A) from M(B) and store it in M(B), if result is not positive, go to instruction C. Descriptions, diagrams, code, tables.

» Enumera, Inc.
   Goal: dominate very low cost, low power, single core CPU market, and have the only ultra-high-end supercomputer on-a-chip system. Because the CPU core is so small, it is possible to put 1000s of cores and memory in one IC chip package.
