Abstract

PURPOSE: To make it possible to carry out processing at a high speed, by providing both a means by which a processing function is halted automatically by a program and a means which is able to release the halted status by the other processor, in case such a program as requires a halt of processing is executed.
CONSTITUTION: In case a processor A has to send a data to a processor B for convenience sake of its own processing, and also is executing a program whose next processing cannot be executed until it is sent out, the processor A sets a data for transmission to a register 3, and sends a data transfer request signal 1 to the processor B in accordance with a data transfer instruction from ROM. At the same time, the processor A drives a halt controlling circuit 6 in accordance with the data transfer instruction in order to perform a halt operation. On the other hand, B receives the request signal 1 from A, writes a data from the register 3 in a register 4 through a data bus 5, sends a transfer end signal to A, and releases the halted status.
