PURPOSE:To simplify a multiprocessor system on the whole by performing data transfer between a submicroprocessor and another microprocessor through a main microprocessor without fail. CONSTITUTION:The main microprocessor 1 has a main/sub function discrimination means, main function executing means, and hardware control means, and the submicroprocessor 2 has a sub function executing means separated from the main microprocessor 1. The data transfer between the submicroprocessor 2 and another microprocessor is carried out through the main microcporcessor 1 without fail. The main microprocessor 1 is only provided with the control function of a hardware part 4, which is then controlled on the basis of data from the submicroprocessor 2 and the other processor 3. |
