Abstract
A memory controller for heterogeneous computer processors dynamically adjusts access priorities by the different processors to maximize performance in the execution of a single parallel application program on both processor architectures. In one embodiment, the memory controller predicts sequential memory accesses by the processor having higher memory latency or fewer access requests to lockout the other processor during those sequences for improved implementation of the intended prioritization.
