Abstract
A logical circuit which is capable of serving not only as a shift register but also as counter, comprises a cascade-connection of flip-flops of the same number as the number of bits required. The flip-flops have an input connected to a logical gate group composed of gates which are opened and closed by a shift signal and a count signal. The logical circuit does not require that a flip-flop be included for each shift register part and counter part for each bit, but only requires one flip-flop to perform both the count and shift function. The logical circuit is capable of performing an independent operation of a shift register, an independent operation of a counter and a compound operation of inputting data in a serial fashion for initialization and outputting counted data in a serial fashion. With the logical circuit of the present invention, the number of gates used is greatly reduced as compared with the prior art shift register/counter circuit; accordingly, the circuit of the present invention is of particular utility when formed as a large scale integrated circuit.
