Abstract

See full text

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.
