<P>PROBLEM TO BE SOLVED: To provide a multi-task system for excluding as much as possible the competition of polling processing between a plurality of tasks with a much simpler configuration. <P>SOLUTION: An arbitration control part arbitrates processing requests to be output by a plurality of polling tasks, and outputs a processing start/permission signal to the polling task whose processing request has been permitted. The plurality of polling tasks output the processing requests in each of respectively set polling cycles, and each of the polling cycles is set to an integral multiple of a reference cycle. The plurality of polling tasks respectively measure standby time since the processing requests are output to the arbitration control part until the permission signal is given, and delay a timing in which their own polling cycles are started next only for the standby time. <P>COPYRIGHT: (C)2013,JPO&INPIT |
