Data processing with a self-timed approach to spurious transitions

摘要

A digital electronic device includes a digital circuit responsive to a logic transition at an input thereof to produce at an output thereof a spurious logic transition ultimately followed by a stable logic level. A transition detector produces a detection signal in response to the logic transition at the digital circuit input, the transition detector including a latch circuit having an output for producing the detection signal. A self-timed circuit receives the detection signal and, after delaying for a suitable time, produces a done signal. A switching circuit is responsive to the done signal to connect the digital circuit output to a selected logic node.
