4 Bit Siso Shift Register Circuit Diagram. Below is a single stage shift register receiving. That covers the parallel out part.
The shift register concept is widely used in dsp based algorithms as each shift left corresponds to multiplying the data by 2 and each shift right corresponds to dividing the data by 2. The logic circuit diagram below shows a generalized serial in serial out shift register. A serial in serial out shift register may be one to 64 bits in length longer if registers or packages are cascaded.
Here the data word which is to be stored is fed bit by bit at the input of the first flip flop.
Serial in serial out siso shift registers are a kind of shift registers where both data loading as well as data retrieval to from the shift register occurs in serial mode. A simple serial in serial out 4 bit shift register is shown above the register consists of 4 flip flops and the breakdown of how it works is explained below. The shift register concept is widely used in dsp based algorithms as each shift left corresponds to multiplying the data by 2 and each shift right corresponds to dividing the data by 2. The block diagram of 3 bit siso shift register is shown in the following figure.
