ABSTRACT:
In a cell delineation circuit, an input signal is converted into parallel signals, and a plurality of parallel signals (i.e. series of parallel signals) which are shifted one bit by one bit from each other are formed from those parallel signals. CRC (Cyclic Redundancy Check) calculations are executed in parallel for the plurality of parallel signals. A series in which a pattern to be calculated satisfies a CRC rule is determined from results of the CRC calculations, and this series is generated, thereby establishing a cell delineation.
