System and method for controlling the competition between processors, in an at-compatible multiprocessor array, to initialize a test sequence

摘要

A multiprocessor array where any single multiprocessor can be needed to execute a prescribed sequence and more than one of the processors may compete to initialize this sequence, and wherein a "semaphore port" SP is coupled to all processors, this port SP being adapted to normally signal "GO", but after "first-access" by a said processor, which thus becomes a "selected processor", to thereupon signal "STOP" to all other, "non- selected", processors, and so deny access until a given test sequence is completed.
