A new architecture for performing systolic optical recognitiori of long codes is introduced. The resulting system is quite robust in that it is insensitive to time of arrival of the code word and to errors in recognizing parts of the code. The advantages, besides robustness, of this system are the use of simple, available components (independent of code word length), high speed, and the small number of components required.
