PURPOSE:To require no exchange operation of the ROMs of all slave processor modules by writing a program for an IPL in a memory circuit in the slave processor module from a master processor module. CONSTITUTION:A memory writing circuit 35 in the slave PUM30 operates through an instruction command transmission circuit 24 by a PU21 in the master processor module PUM20 at the time of the IPL and the program of a file device 40 is written to the memory circuit in the PUM30 according to a writing signal 37. Then, according to a reset instruction to the slave PUM30 from the circuit 24, a signal forming circuit 36 in the slave PUM30 operates and a PU31 is reset by a reset signal 38. Thereafter, the PU31 reads the program of the memory circuit 34, in the master PUM20, by a communication bus 10 between the PUMs via the file device 40, the PU21, a memory 22 and an interface 20 and by the interface 33, the PU31, the memory 32 of the slave PUM30, the IPL is performed. |
