PURPOSE:To send information at a high speed between CPUs, by constituting a system so that a local memory is held in common with a master CPU, and a local memory access from the master CPU is allowed to a slave CPU. CONSTITUTION:This multiprocessor system is provided with a master CPU1 and plural slave CPUs 4, 5, and on a bus line L of each slave CPU, a local memory 3 and program storing memories 6, 7 are provided. When an access request is sent to the local memory 3 fom the master CPU1 in the instruction fetching cycle of the slave CPUs 4, 5, the local memory is detected from bus lines L1, L2 of the related slave CPUs 4, 5 and is connected to the bus line L of the master CPU1. |
