ABSTRACT:
A multiprocessor system used, for example, in a personal computer, wherein different types of microprocessors are used independently of the architecture of each microprocessor. The system includes a control register, a control circuit, and a common peripheral circuit mounted, for example, on a main board, and a plurality of kinds of microprocessors each mounted, for example, on a sub-board connected to the main board. The control circuit transmits a halt request signal to a first microprocessor which is currently operating, in response to coincidence between an output signal of the control register and the status signal indicating that a second microprocessor is in a halt condition, when the output signal of the control register is changed by the first microprocessor. Then, the control circuit releases a halt request signal applied to the second microprocessor in response to coincidence between a status signal indicating that the first microprocessor has entered into a halt condition and the output signal of the control register.
