Abstract

PURPOSE: To perform efficient bus coupling, by making usable the memory connected to opposing bus with the address conversion table corresponding to each processor and connecting an arbitrary memory base of the processor to an arbitrary memory base of opposing.
CONSTITUTION: A plurality of processors 1001...100n of the first group are connected to the bus 400, and the memories 1101...110n are connected to each processor. On the other hand, the processor not shown in the second group in the appended figure and the common memory 200 are connected to the bus 500, and the buses 400 and 500 are connected with the address conversion unit 300 constituted with a plurality of address conversion table selected by the specific name of a plurality of processors 1001...100n included in the first group. Further, output is made from the processors 1001...100n included in the first group. The memory address is converted to the common address 200. Thus, the bus coupling can efficiently be made.
