Abstract

We had developed a preload method for non-numerical programs. It used heuristics to identify which load instructions tend to cause a cache-miss on non-numerical programs. We have improved this method to apply to numerical programs. We use a new heuristic that load instruction in a loop with a constant or variable address increment tends to cause a cache-miss. We show that most of load instructions which tend to cause a cache-misss are selected by the heuristics for any type of programs. We also show that the reduction in the execution time for numerical programs ranges from 5% to 27% and that the method is effective for numerical programs with long cache miss latency.
