Data transfer system among microprocessors

Abstract

Abstract PURPOSE:To reduce processing with reference to change of connection of a queue and to improve the performance of bucket switching, by providing a hardware queue for storing addresses of software queues generated in a common memory. CONSTITUTION:A bucket switchboard consists of a microprocessor CPU, local memory LM, local bus LB, circuit control unit LCU, common bus CB, and a bus interface unit BIU, and bucket switching processing is performed by plural communication control processor modules CCP. The CCPs are connected mutually through the common bus CB; and a common memory CM for buffering data during data transfer among processors, and a hardware pointer queue HQ stores address of software data queues in the common memory and is connected to the common bus.
