Pipo Shift Register. The logic circuit given below shows a parallel in parallel out shift register. By electrical4u parallel in parallel out pipo shift registers are the type of storage devices in which both data loading as well as data retrieval processes occur in parallel mode.
Using shift registers we can shift data through a series of flip flops. Shift registers parallel serial pipo piso siso sipo in digital electronics a collection of flip flops which are memory elements is known as a register. In pipo only 1 clock is required for entering the data and no more clock are required for receiving it data receive out instantly on other side parallel terminals so total 1 0 1 clock is required to process data.
The pipo shift register is the simplest of the four configurations as it has only three connections the parallel input pi which determines what enters the flip flop the parallel output po and the sequencing clock signal clk.
This circuit consists of three d flip flops which are cascaded. This circuit consists of three d flip flops which are cascaded. Using shift registers we can shift data through a series of flip flops. 4 bits pipo shift register the input data at each of the input pins from d0 to d3 are read in at the same time when the device is clocked and at the same time the data read in from each of the inputs is passed out at the corresponding output from q0 to q3.
