Abstract:
Process, cache memory, computer product and system for loading data associated with a requested address in a software cache. The process includes loading address tags associated with a set in a cache directory using a Single Instruction Multiple Data (SIMD) operation, determining a position of the requested address in the set using a SIMD comparison, and determining an actual data value associated with the position of the requested address in the set.
