Abstract:
A method for weak stream software data and instruction prefetching using a hardware data prefetcher is disclosed. A method includes, determining if software includes software prefetch instructions, using a hardware data prefetcher, and, accessing the software prefetch instructions if the software includes software prefetch instructions. Using the hardware data prefetcher, weak stream software data and instruction prefetching operations are executed based on the software prefetch instructions, free of training operations.
