Shift Microoperations
Shift microoperation can be used for serial transfer of the data. They are used generally with arithmetic, logic and other data-processing operations. The contents of register can be shifted to left or right. During a shift-right operation serial input transfers a bit into leftmost position. The serial input transfers a bit into rightmost position during a shift-left operation. There are three types of the shifts, logical, circular and arithmetic.
