Abstract

A scheduler for making an execution plan by a simple processing without impairing the real time property and the constant period property of each constant period process. The shortest execution request period out of the execution request periods of constant period processes is set as the period of the execution unit of an execution plan, and the largest number of processes executed in the period is set as the number of slots by dividing the set period into a predetermined number of slots. According to the execution request period of each constant period process, one of the constant period processes is allocated to the corresponding slot as necessary to make an execution plan.
