PURPOSE:To reduce the storage area of each processor as well as the processing load by using the receiver processor address contained in a message set on a bus and the message type to read a message designation memory means and storing only those messages registered to said designation memory means into a message memory means. CONSTITUTION:The message selection/storage devices 110 and 310 are connected to a system bus. The messages designated by the address of message designating signal (e) or (g) is written to the devices 110 and 310 by a personal computer 400 and a microcomputer 320 in response to the write signal (c'). At the same time, the latest write end address (l) is reported to both computers 400 and 320. For the written messages, the contents designated by the read address signal (m) are read out to both computers 400 and 320 in the form of the memory output signal (r) when the read signals (o) are supplied from both computers. |
