PROBLEM TO BE SOLVED: To synchronize a slave processing to a main processing to enhance the processing efficiency of a system in a multiprocessor control system comprising a main processor repeating the main processing 10 at a period T1 and a slave processor 2 the slave processing 20 for providing necessary information to the main processing 10 in a predetermined execution time asynchronously with the main processor, wherein the main processor executes, by use of information consisting of the latest processing result of the slave processing that is found at the time of starting the main processing of every period T1, the main processing of a period concerned. SOLUTION: The kinds of all pieces of information provided to the main processing by one slave processing is divided to one or more predetermined kinds, so that the processing time of the slave processing for determining information on every section is the period T1 of the main processing or less. The slave processor measures the period T1 of the main processing by a main processing monitoring timer 6, and repeats the execution of the slave processing for determining information on every section, with respect to all the sections, while synchronizing the processing for one section with the period T1.
