Abstract

A new, microcoded, RISC-type system is proposed and presented. The microcode is stored in a 256 x 64 PROM Nanomemory in the CPU. The 8-bit opcode of each instruction is a direct address to the Nanomemory. Each Nanomemory 64-bit word (horizontal microcode) corresponds to a specific machine language instruction. A large 2048 x 32 CPU Register file, using the register window approach, is implemented. A bit-sliced (AMD2900) prototype is currently under construction.
