Abstract :
A circuit which identifies a 64-bit synchronization word in a serial incoming data stream is discussed. The signature is identified when the incoming data stream matches a previously known and stored signature. It is also possible to program the number of bit errors permissible for recognition of the signature. The circuit was fabricated in a 1.5- mu m CMOS technology for use in a D2MAC television decoder. The circuit operates at data rates up to 20 MHz and covers an area of 1.4*0.1 mm/sup 2/. The possible applications in image recognition and string identification in text are presented.<>
