Method and apparatus for data collision detection in a multi-processor communication system

摘要

A method and apparatus for data collision detection and resolution in a multi-processor communication system. The system includes a plurality of processors coupled via a common bus. When it is required that one processor communicate with another processor, the first processor determines whether a data collision flag is set. The processor then checks a number of indicators to determine whether the identity of the transmitting processor is what it is expected to be. If a data collision is found, the processor waits a selective time before transmitting a message. The processor then repeats the data collision checking and transmitting the message to the other processor when no data collision is found. The time to wait is dependent upon the identity of the processor and is table driven.
