Anomalous Behavior of Synchronizer and Arbiter Circuits
April 1973 (vol. 22 no. 4)
pp. 421-422
T.J. Chaney, Computer Systems Laboratory, Washington University
Observations are shown of oscillatory and metastable behavior of flip-flops in response to logically undefined input conditions such as those that occur in synchronizers and arbiters. Significant systems failures have resulted from this fundamentally inescapable problem that is generally not appreciated by system designers and users.
Index Terms:
Asynchronous interactions, binary switching time, flip-flop metastable region, interrupt failure, synchronizer failure mode.
