Abstract

PURPOSE:To efficiently execute the inter-CPU communication and the usual processing operation in each CPU, by writing a message in case of the inter- CPU communication, in a dedicated memory, and transferring its contents to other CPU through an inter-CPU communication leased bus. CONSTITUTION:A message data in case of an inter-CPU communication is transferred through an inter-CPU communication leased bus 13 without using a system bus 12, and also, its message data is stored in an inter-CPU communication dedicated memory 24 provided in each unit, therefore, a system is not used for the inter-CPU communication. Accordingly, the inter-CPU communication can be executed efficiently without obstructing a usual program processing in each CPU.
