ABSTRACT:
A parallel processor system is composed of N processors, N memories and the interconnection where N.times.N data buffers are two-dimensionally placed. Each data buffer provides a data memory with an empty signal and an AND gate. Each memory outputs the transmit completion signal. This signal is input into the corresponding N data buffers and is ANDed with the corresponding empty signal. Each processor inputs the transfer completion signal. This signal is produced by logical-OR among outputs of the AND gates of the corresponding N data buffers. By monitoring the transfer completion signal, each processor recognizes the end of data transfer as data transmission to the corresponding processor ends.
