BLOCK USED FOR IMPLEMENTATION 

EXPLANATION :

          Barrel sifter which are triggered using clock operate sequentially. For a shift or rotate of  N bits you will have to apply N clock cycles. Mux can be used to make the shift/rotate operation faster by converting the sequential circuit to computational logic. Just by application of a single clock cycle N shift/rotate can be done. The circuit used for implementation above is a simple configuration for rotate right operation. If you want to customize the design for shift(right/left) or rotate(R/L) the select line connection has to be changed accordingly. Also have a look at our exciting new course for free
