PURPOSE:To ensure executing synchronism of programs by using a system control CPU to control the start and the execution end response of the program of each CPU and controlling a start instruction and the end of execution of the program through each CPU. CONSTITUTION:When a system bus 7 is connected to a CPUn+1, a system control CPU 1 sets a start instruction to be given to the CPUn+1 to a start control part 3. Then the start instruction is transferred to a start instruction accepting part 5n+1 of the CPUn+1 and a program D is carried out. An execution end response output part 6n+1 is set after the program D is carried out. Then the start instruction is also transferred to an end response control part 4. The part 4 starts a program C loaded on a CPUn via a control part 3 after recognizing the program started next as the program C of the CPUn via a program table. Furthermore, the part 4 starts a program E to participate the CPUn+1 in a system. |
