ABSTRACT:
Performance of a heterogeneous multiprocessor is reduced as much as possible within a short time without any awareness of parallelization matched with a configuration of the heterogeneous multiprocessor. In a heterogeneous multiprocessor system, tasks having parallelism are automatically extracted by a compiler, a portion to be efficiently processed by a dedicated processor is extracted from an input program being a processing target, and processing time is estimated. Thus, by arranging the tasks according to PU characteristics, scheduling for efficiently operating a plurality of PU's in parallel is carried out.
