Abstract
PURPOSE: To enable to select the processing of each data processor to either of parallel and master slave processing mode, by giving the functions requesting the processing to the data processor, to the controller receiving the data inputted from the terminal unit.
CONSTITUTION: In the system providing the controller 2 receiving the data from a plurality of terminal units 3-0, 3-1 ... 3-n, and the data processors 1-0 and 1-1 executing the processing based on the data from the controller 2, the controller 2 is provided with the distribution circuit 4 parallely feeding the data to the units 1-0 and 1-1 and feeding either of them selectively, collation circuit 3 collating the result of processing, and the selection circuit 5 connecting the controller 2 to the units 1-0 and 1-1. Further, the selection control unit 9 is controlled with the controller 2, and the units 1-1 and 1-0 are taken as parallel processing mode or master slave processing mode in which one is taken as master and another is taken as slave processor.
