<p>PURPOSE:To shorten the nonoperation time of a circuit by arithmetic in a job and the execution of a branch instruction by classifying the arithmetic of data in different formats in the job by the kinds of arithmetic of the same data formats and putting respective microcomputers in charge of the different kinds of arithmetic, and dividing a routine group determined by branching in the job and executing them by the respective microcomputers. CONSTITUTION:Each of the microcomputers 10 internally has a communication module 16, a bus switch which operates in relation with an arbiter on a board, and a common memory 20 which operates similarly to an internal memory. As a specific microcomputer 10 among the respective microcomputers 10 executes an OS, the job, i.e., software put on the market is transferred from a floppy disk or hard disk to the common memory 20. Here, the OS classifies the job by routine groups determined by branching and also by the data formats of the data, and puts the respective microcomputers 10 in charge. The job is handled as a task and executed by a CPU 11.</p> |
