Universal Shift Register Circuit Diagram. A universal shift register is a do everything device in addition to the parallel in parallel out function. The design of a 4 bit universal shift register using multiplexers and flip flops is shown below.
Design of universal shift register. Above we apply four bit of data to a parallel in parallel out shift register at d a d b d c d d. The block diagram of 3 bit siso shift register is shown in the following figure.
The block diagram of 3 bit siso shift register is shown in the following figure.
The purpose of the parallel in parallel out shift register is to take in parallel data shift it then output it as shown below. Above we apply four bit of data to a parallel in parallel out shift register at d a d b d c d d. The design of a 4 bit universal shift register using multiplexers and flip flops is shown below. Such a shift register capable of storing n input bits is shown by figure 1.
