Abstract
A system comprising a cache memory connected to a processor and a main memory wherein the processor has a unit for outputting a discrimination signal that indicates whether the access to said cache memory is a sequential address data access or a non-sequential address data access, and the cache memory has a unit for changing the processing in a cache-miss state based on the output discrimination signal. In the case of the non-sequential address data access, unnecessary access to the main memory is suppressed to reduce the penalty in the cache-miss state and, hence, to improve the efficiency of the whole system by realizing a high-speed operation.
