PURPOSE:To permit loading by a single means and improve processing speed by decoding the command to be sent to other processing device which operates dependently to a CPU and instructing the storage of the program when it is a loading command. CONSTITUTION:When the exchange of communication is permitted from a master program control device to a subprogram control processing device, the command transmitted via a command line 2 is received in a command decoder 1 by the strobe pulse transmitted through a strobe line 3. If the decoded command is a loading command and is an operating system (OS), a loading circuit 4 is started. The program transmitted through a data line 6 is loaded by this output into a memory 5. Upon completion of this OS, the device is initialized and an interrupt signal is generated from an interrupt signal generating circuit 7. This procedure is repeated and program loading is accomplished. Thereby, the processing speed is improved by the single procedure. |
