Bit Shifter Diagram. This component design is for a natural size 4816 barrel shifters that perform shift right logical rotate right shift left logical and rotate left operations depending on the instantiation parameters. 4 bit shift register the sn5474ls95b is a 4 bit shift register with serial and parallel synchronous operating modes.
The rightleft is the control input signal which allows data shifting either towards right or towards left. Your timing diagram will look like the figure below. Data can also be loaded serially see the function table.
The simulation results are carried out using silvaco software.
Block diagram of logical left shift barrel shifter verilog module the verilog module of logical left shift barrel shifter is shown in figure 2. In cased of 8 bit parallel communication device needs to send the data to the serial receiving device then an 8 bit shift register will be used. For address generation unit by a. Below is the diagram of 4 bit bidirectional shift register where dr is the serial right shift data input dl is the left shift data input and m is the mode select input.
