Abstract
PURPOSE:To perform processing rapidly with simple circuit constitution by comparing reference data, stored in a memory, with arrival data and by generating an output only when the both are coincident. CONSTITUTION:A memory 1 stores reference data and comparison data and sends the stored data to a latch circuit 2 and a comparator 3. This comparator 3 compares data stored in the latch circuit 2 with the data from the memory 1 and sets an FF4 when both the data are coincident or resets it when not. A timing circuit 5, on the other hand, receives a clock 5a and a write pulse 5b to generate timing signals for the circuit 2, compartor 3, and FF4. Further, a counter 6 receives a clock from the circuit 5 to generate a comparison address signal, and a counter 7 generates a reference address signal.
