PURPOSE:To control the interchange of data between or among microprocessor by providing holding circuits corresponding to respective microprocessors and by setting one of holding circuits, which corresponds to a reception-side processor, by a transmission-side processor. CONSTITUTION:To say exactly, each of microprocessors 1a-1d consists of interface 7, local memory 8, local input-output circuit 9, and processor 10. Further, holding circuit group 11 is provided which is individually selected from the common bus 2 side and corresponds to processors 1a-1d. Then, the holding circuit in circuit group 11 which corresponds to a transmission address processor is set via common bus 2, so that the hold output of the holding circuit can be used as an interruption signal. |
