Zusammenfassung:A system and method for increasing computing throughput through execution of parallel data error detection/correction and cache hit detection operations. In one path, hit detection occurs independent of and concurrent with error detection and correction operations, and reliance on hit detection in this path is based on the absence of storage errors. A single error correction code (ECC) is used to minimize storage requirements, and data hit comparisons based on the cached address and requested address are performed exclusive of ECC bits to minimize bit comparison requirements.
