CACHE CONTROL DEVICE FOR PREFETCHING AND PREFETCHING METHOD USING CACHE CONTROL DEVICE

摘要

The present examples relate to prefetching, and to a cache control device for prefetching and a prefetching method using the cache control device, wherein the cache control device analyzes a memory access pattern of program code, inserts, into the program code, a prefetching command generated by encoding the analyzed access pattern, and executes the prefetching command inserted into the program code in order to prefetch data into a cache, thereby maximizing prefetching efficiency.

主权项

1. A cache control device comprising:
a pattern analysis processor configured to analyze a memory access pattern of program code; a code conversion processor configured to generate a prefetch instruction by encoding the analyzed memory access pattern, and to insert the generated prefetch instruction into the program code; and a prefetch processor configured to prefetch data into a cache in response to an execution of the prefetch instruction inserted into the program code.
