SYSTEM, APPARATUS AND METHOD FOR PREDICTING ACCESSES TO A MEMORY

A system, apparatus, and method are disclosed for predicting accesses to memory. In one embodiment, an exemplary apparatus comprises a processor configured to execute program instructions and process program data, a memory including the program instructions and the program data, and a memory processor. The memory processor can include a speculator configured to receive an address containing the program instructions or the program data. Such a speculator can comprise a sequential predictor for generating a configurable number of sequential addresses. The speculator can also include a nonsequential predictor configured to associate a subset of addresses to the address and to predict a group of addresses based on at least one address of the subset, wherein at least one address of the subset is unpatternable to the address.
