Abstract
An apparatus and method for controlling and providing a robust, single entry cache memory is described in connection with an on-board cache memory integrated with a microprocessor. By implementing the single entry cache memory in a redundancy array of the cache memory, CPU debug procedures may proceed independently of the cache debug by disabling part of the cache memory and enabling a dedicated single entry cache in the redundancy array. Use of a cache redundancy array for the single entry cache imposes no area or latency penalties because the existing cache redundancy array already matches the latency of the cache.
