Abstract
PURPOSE: To control the standby time due to bus occupancy by dividing multiprocessor units into the "m"-number groups and by attaining mutual and independent access to one bus-sharing memory provided to each group among processors in the same group while respective groups attain access to address areas of other groups in the bus-sharing memories.
CONSTITUTION: Bus-sharing memories 5A to 5D of minor groups 1A to 1D have address areas 11A to 11D to other groups and their own address areas 12A to 12D. When work processor 2A assigns address X in actual memory area 12A of memory 5A, control part 8A allows the occupancy of the common bus and addressing is done, but when it assigns B in the address area to another group, address X is extended 10A and access to a fixed address in memory 5B is attained via bus control part 9. Control part 9 determines the order of access from one group to another. In this way, each work processor can attain access without reference to the access address.
