Method and apparatus for forwarding data in a hierarchial cache memory architecture |
摘要 |
A method and apparatus for forwarding data in a hierarchial cache memory architecture is disclosed. A cache memory hierarchy includes multiple levels of cache memories, each level having a different size and speed. A command is initially issued from a processor to the cache memory hierarchy. If the command is a Demand Load command, data corresponding to the Demand Load command is immediately forwarded from a cache having the data to the processor. Otherwise, if the command is a Prefetch Load command, data corresponding to the Prefetch Load command is held in a cache reload buffer within a cache memory preceding the processor.
