MULTI-CORE PROCESSOR SYSTEM, MULTI-CORE PROCESSOR SYSTEM CONTROL METHOD AND MULTI-CORE PROCESSOR SYSTEM CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce surplus of computing capabilities, and attain power saving.SOLUTION: An APL 103 is other core different from a specific core executing a specific process through a detection part 202, and detects that, of a plurality of pieces of software, other software different from a specific software having an equivalent function to the specific process is in execution. After the detection, the APL 103 extracts request values of computation capabilities of the specific software and the other software from a software capability request table 201 through an extraction part 203. Using the extracted request values, when the APL 103 judges that a total of the request values of the computation capabilities of the specific software and the other software is equal to or less than a computation capability value of the other core through a surplus judgement part 204, the APL 103 allocates the specific software through an allocation part 205. After allocated, a PMU 102 pauses a DSP 104 through a pause part 206.
