TASK SCHEDULE DEVICE AND TASK SCHEDULE METHOD

摘要

PROBLEM TO BE SOLVED: To achieve safer processing and high efficiency of using a CPU with respect to a task schedule.;SOLUTION: A task scheduling device for scheduling the assignment of a CPU using time to a plurality of tasks includes: a clock part which measures the actual processing time of the tasks; a time management table for managing the processing time of each of the plurality of tasks; and a completion calculation anf management unit which corrects an error of a task completion time in a predetermined period obtained by the clock part within a predetermined processing period stored in the time management table. The completion calculation and management unit corrects the error of the task completion time on the basis of a result completion time obtained by the clock part, and performs scheduling of the tasks by reflecting the correction to the completion time of the next period.;COPYRIGHT: (C)2011,JPO&INPIT
