Abstract

By expanding the cache address invalidation queue into bit slices for holding odd invalidation addresses and even invalidation addresses and also by providing a more efficient series of transition cycles to accomplish cache address invalidations both during a cache hit or a cache miss cycle, the present architecture and methodology permits a faster cycle of cache address invalidations when required and also permits a higher frequency of processor access to cache without the processor being completely locked out from cache memory access during heavy traffic and high level of cache invalidation conditions.
