LOCAL CACHE BLOCK FLASH COMMAND

PROBLEM TO BE SOLVED: To provide a local cache block flash command. SOLUTION: A microprocessor and a related compiler support a local cache block flash command, where the execution unit of a processor determines an effective address. The processor makes a cache subsystem commit all pending references to the cache blocks, corresponding to the determined effective addresses. When a cache line referred to is corrected in a local cache (a cache subsystem, corresponding to the processor under execution of instructions), it is written back to a main memory. When the block referred to is valid in the local cache, although it is invalidated, but this is only the local cache. When the block referred to is not valid in the local cache, invalidation is not be carried out. A remote processor, which receives the local cache block flash instruction from the other processor through the system, ignores this command. COPYRIGHT: (C)2005,JPO&NCIPI
