Abstract

Methods for accessing, storing and replacing data in a cache memory are provided, wherein a plurality of index bits and a plurality of tag bits at the cache memory are received. The plurality of index bits are processed to determine whether a matching index exists in the cache memory and the plurality of tag bits are processed to determine whether a matching tag exists in the cache memory, and a data line is retrieved from the cache memory if both a matching tag and a matching index exist in the cache memory. A random line in the cache memory can be replaced with a data line from a main memory, or evicted without replacement, based on the combination of index and tag misses, security contexts and protection bits. User-defined and/or vendor-defined replacement procedures can be utilized to replace data lines in the cache memory.
