Abstract
A novel on-chip cache memory and method of operation are provided which increase microprocessor performance. The cache design allows two cache requests to be processed simultaneously (dual-ported) and concurrent cache requests to be in-flight (pipelined). The design of the cache allocates a first clock cycle to cache tag and data access and a second cycle is allocated to data manipulation. The memory array circuit design is simplified because the circuits are synchronized to the main processor clock and do not need to use self-timed circuits. The overall logic control scheme is simplified because distinct cycles are allocated to the cache functions.
