Title: Serial word comparator
Inventor: ERHART RICHARD A
IPC: G06F11/00
Filed: 1990-01-30
Granted: 1994-01-04
Abstract: ABSTRACT    An apparatus for determining if a received binary word corresponds to the true or complement version of a stored binary word includes means for serially multiplexing the bits of each binary word to the inputs of an exclusive OR gate.  The exclusive OR gate generates a logical high signal each time a mismatch occurs.  These signals are applied directly to an error counter and, after inversion, to a match counter.  The contents of the error counter and match counter are compared to a stored threshold number.  A first signal is generated if the contents of the error counter exceeds the threshold.  A second signal is generated if the contents of the match counter exceeds the threshold.  Upon the occurrence of both signals, the serial comparison process is terminated.
