Configurable cache for a microprocessor

摘要

A cache module for a central processing unit has a cache control unit with an interface for a memory, a cache memory coupled with the control unit, wherein the cache memory has a plurality of cache lines and the cache memory is programmable to assign a first set of cache lines to cache instructions and a second set of cache lines to cache data, and wherein the cache control unit has a programmable function which forces a data cache into the second set of cache lines while instructions are executed from the first set of cache lines.
