Abstract
A method of two-way communication in a multiprocessor system in which two-way data communication is effected between a first processor and a second processor via a common memory. The first processor sequentially writes data A, B, C, . . . , F into the common memory, and forms a coupled queue. If the data A, B, C among the data A, B, C, . . . , F in the coupled queue are sequentially read by the second processor, the coupled queue is divided into a first partial queue constituted by the data D, E, F and a second partial queue constituted by the data A, B, C. The second processor is capable of sequentially reading the data D, E, F from the first partial queue, while the first processor is capable of sequentially reading the data A, B, C from the second partial queue. When the second processor sequentially reads the data A, B, C, . . . , F and the first processor then sequentially reads the data A, B, C, . . . , F in the above-described manner, it follows that the data A, B, C . . . , F are transmitted from the first processor to the second processor and are then returned from the second processor to the first processor. Two-way communication is thus established between the first and second processors.
