Comparison circuit comprising a masking mechanism for masking transient differences, comparison circuit system, and processing device comprising such comparison circuit.

摘要

A masking comparison circuit outputs a signal "non-correspondence" if two binary signals received are unequal. However, there are provided masking means for masking this non-correspondence signal unless both binary signals for some time have been stable and, moreover, different. A comparison circuit of this kind forms part of, for example a data processing device based on redundancy.
