PURPOSE:To shorten the transfer time of a control program from an external memory device connected to the 1st processor to the 2nd processor by directly specifying a memory in the 2nd processor from the 1st processor. CONSTITUTION:The 1st muCPU 1 connected to the external memory device 3 is connected to the 2nd muCPU 4 which is not connected to the external memory device to transfer the control program to be executed by the 2nd muCPU 4 from the 1st muCPU 1 to the 2nd muCPU 4. At that time, memory addresses in the 2nd muCPU 4 are divided into plural address spaces and a part of memory addresses in the 1st muCPU 1 are successively made to correspond to the plural address spaces to directly specify a memory address of the 2nd muCPU 4 from the 1st muCPU 1. |
