Abstract
In case of a task scheduling processing that assigns plural divided execution program tasks to plural processor units, a multiprocessor system using SOI/MOS transistors employs two processes; one process is to determine an order to execute those tasks so as to reduce the program execution time and the other process is to control the system power upon task scheduling so as to control the clock signal frequency and the body-bias voltage to temporarily speed up the operation of a processor unit that processes another task that might affect the processing performance of one object task if there is dependency among those tasks.
