Abstract
This invention is a cache memory employing a tag bypass controller to detect a memory access to the same cache line as a last cache miss address and a last cache hit address. This information is uses for efficient data accesses and forwarding. Registers store the last miss-address and the last hit-address and corresponding valid flags. These hardware features allow reduced tag-RAM accesses and greatly reduce the latency required to fully re-stock a missed cache line.
