ABSTRACT:
A data detector detects an identification signal of a prescribed format from N-bit wide parallel input data (where N is a natural number). The data detector includes P first comparing sections (where P is a natural number), Q second comparing sections (where Q is a natural number), and a determining section. Each of the P first comparing sections compares one of first P data of continuous (P+Q) data in the parallel input data with a first pattern. Each of the Q second comparing sections compares one of Q data following the P data with a second pattern. The determining section determines whether the identification signal has been detected or not according to a comparison result of the P first comparing sections and a comparison result of the Q second comparing sections.
