Abstract
Prefetch instructions having a function to move data to a cache memory from main memory are scheduled simultaneously with execution of other instructions. The prefetch instructions are scheduled by replacing, with the original prefetch instructions, the virtual prefetch instructions obtained by unrolling a kernel section of the schedule constituted by generating a dependency graph having dependent relationships between the prefetch instruction and the memory reference instruction, and then applying the software pipelining thereto, or by further unrolling the kernel section of the constituted schedule to delete the redundant prefetch instructions, or further by applying the software pipelining to the dependency graph which is formed by combining a plurality of prefetch instructions and replacing the prefetch instructions with virtual prefetch instructions.
