The logic circuit of this register is shown above, and the circuit can be built with 4-D flip-flops. If the high mode is chosen then the data will be moved to the right side, as well as if the low mode is chosen then the data will be moved to the left side. These registers are capable of moving the data in the right side otherwise left side based on the selection of mode (high or low).

These operations can be performed with a register to move the data in any direction. In this type of shift register, if we move a binary number toward the left with one place, it is equal to multiplying the digit with two & if we move a binary number toward the right with one place it is equal to separating the digit with two. Parallel in-Parallel out (PIPO) Shift RegisterĪ PIPO (Parallel in Parallel out) shift register can be utilized like a temporary storage device, similar to SISO Shift register, and it performs like a delay element. Here the data is given as input individually for every flip-flop, as well as the output is also received separately from every flip flop.

In this type of register, there is no interconnection between the individual flip-flops as no data serial shifting is necessary. The clear (CLR) signal and clock signals are connected to all the 4 flip flops. The circuit consists of four D flip-flops which are connected. The logic circuit given below shows a parallel in parallel out shift register. The shift register, which allows parallel input (data is given separately to each flip flop and in a simultaneous manner) and also produces a parallel output is known as Parallel-In parallel-Out shift register. Parallel in-Parallel out (PIPO) Shift Register The applications of these registers include converting parallel data to the serial data. Once the same CLK signal is given to every flip flop, then all the flip flops will be synchronous with each other. The earlier FF output, as well as parallel data input, is connected toward the multiplexer’s input & multiplexer’s output can be connected to the second flip flop.

Parallel in-Serial out (PISO) Shift Register However, the input data is connected separately to every FF using a multiplexerat every FF’s input. This circuit can be built with four D-flip-flops, where the CLK signal is connected directly to all the FFs. The Parallel in Serial out (PISO) Shift Register circuit is shown above.
