Abstract
A RISC processor utilizes a segmented cache to reduce word line loading to reduce power consumption and increase speed. Address bit are predecoded to activate a selected segment. Groups of instructions are accessed from the cache in parallel and stored in register. The stored instructions are fetched from the register during sequential instruction execution to reduce the number of cache accesses.
