A processing system includes a cache memory system which receives an address and a memory request from a processor. Simultaneously, information is accessed responsive to the address from a main memory and from a cache memory. During access of the information from the main memory and cache memory, it is determined whether the desired information is stored in the cache memory. If so, the information is output from the cache memory; if not, the information is output from the main memory.
