ABSTRACT:
In multiprocessing system executing processing called NUMA prefetch, when a prefetch instruction is issued to a prefetch unit, an address converter converts an address specified by an operand of the instruction into a physical address. A prefetch type determiner determines whether the instruction is an NUMA prefetch instruction or a conventional perfect prefetch instruction. If the instruction is an NUMA prefetch instruction, an address determiner determines whether the physical address is a local address or a remote address. If the address is a local address, the processing of the prefetch instruction is terminated. If the address is a remote address, a cache tag checker checks a cache. When cache hit occurs, the processing is terminated. When cache mishit occurs, a prefetch request is issued to a main storage controller. As a result, data is prefetched from a remote main storage to a cache in a local main storage.
