CACHE MEMORY CONTROL PROGRAM, PROCESSOR INCLUDING CACHE MEMORY, AND CACHE MEMORY CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To improve utilization efficiency of a cache memory.SOLUTION: Provided is a processor-readable cache memory control program for causing a processor to execute a cache memory control step of controlling a cache memory provided commonly to a plurality of processors, the cache memory control process including: a dividing step of dividing the cache memory into sector areas by the number that is the number of processors plus at least 1; an allocating step of allocating the sector areas to processes executed by the respective processors as dedicated cache areas; and a process switching step of, when the process executed by a first processor is switched from a first process to a second process, allocating a free sector area that is not allocated to any processes out of the sector areas to the second process, and releasing a first sector area allocated to the first process.
