PURPOSE:To constitute so that each processor can utilize in common an assigned memory space, by writing a memory mapping table in an address converting device, by a master processor. CONSTITUTION:A master processor 3 inputs in advance a memory mapping table output S0 for assigning slave memory spaces M1, M2-Mn to a common memory space 4 of large memory size which the master processor 3 can control, to an address converting device 5. Subsequently, the memory spaces M1, M2- Mn are assigned to a prescribed position of the common memory space 4, as they are or dividing them. This common memory space 4 can be utilized by executing access by a data address signal SA and SB, respectively, by the master processor 3 and slave processors S1, S2-Sn. |
