We describe a new algorithm for prefetching arrays that are accessed with a compile-time known constant stride. We demonstrate a hardware limitation that has not previously been dealt with (limited off-chip bandwidth) and show its effect on prefetching. Our new algorithm is designed to cope with this hardware limitation. The new algorithm generates prefetches that are more efficient than the standard...
