ABSTRACT:
A microprocessor is configured to execute a prefetch instruction specifying a cache line to be transferred into the microprocessor, as well as an access mode for the cache line. The microprocessor includes caches optimized for the access modes. In one embodiment, the microprocessor includes functional units configured to operate upon various data type. Each different type of functional unit may be connected to different caches which are optimized for the various access modes. The prefetch instruction may include a functional unit specification in addition to the access mode. In this manner, data of a particular type may be prefetched into a cache local to a particular functional unit.
