The main purpose or use of this algorithm is to multiply 2 binary no.s.Booth's Algorithm is multiplies two number in 2's Complement.

General Steps of Booth's Algorithm:-

Step 1:-In step 1 firstly we take a multiplicand BR and multiplier Q(R) and set value of AC,Q(n+1),SC are 0,0,0 respectively.

Step 2:-In step 2 We check Q(n) and Q(n+1).

Step 3:-In step 3 if bits are 0,1 then add BR with AC and after that perform Right Shift Operation.

Step 4:-If bits are 1,0 then perform AC+(BR)'+1 then perform Right Shift Operation.

Step 5:-Check if SC is set as o.

Step 6:-Repeat Step 2,3,4 until SC<--0.
