INTER-PROCESSOR COMMUNICATION PROTOCOL

摘要

: Processors of a multiprocessor system communicate across bus via a low-latency packet protocol featuring per-logical channel input queues and output queues, different perprocessor priorities for sending data packets and data packetacknowledging "quick" messages, and separate buffers for receiving data packets and "quick" messages, respectively. Transmitted data packets afflicted by error, receive buffer overflow, and input queue-full conditions are discarded by the receiving processor and are retransmitted by the sending processor.
