Binary Shifters using Logic Gates

A binary shift is a binary operation that consists of shifting all the digit of a binary number either to the left or to the right by a fixed amount. Binary shifts can be used to multiply a number by a power of 2 (left shit) or to divide a number by a power of 2 (right shift).

Binary Left Shift


A binary left shift is used to multiply a binary number by two. It consists of shifting all the binary digits to the left by 1 digit and adding an extra digit at the end with a value of 0.

Binary Right Shift


A binary right shift is used to divide a binary number by two. It consists of shifting all the binary digits to the right by 1 digit and adding an extra digit at the beginning (to the left) with a value of 0.

8-bit Binary Shifters


A binary shifter is a logic gates circuit that takes a takes a binary input (A) and performs either a left shift or a right shift and outputs the result (S). On the diagram below, input D is used to decide whether a left shit (D=0) or a right shift (D=1) is applied.binary-shift-logic-gates-diagram
