Booth algorithm (multiplication of signed numbers)

Ask for M3m2m1m0xq3q2q1q0:0110x0101 (signed number is in complement, the highest bit is positive or negative)1. Add auxiliary bit: a=0000 q-1=02. Control logic judgment:①Q0Q-1=01: A=a+m then A, Q, Q-1 arithmetic right shift (two steps)②q0q-1=10: A=a-m then A, Q, Q-1 arithmetic right shift (two steps)Complement plus minus: (A-M) complement =a complement + (-m) complement③q0q-1=00 or 11 o'clock: A, Q, Q-1 arithmetic right shift (one step)Complement right shift: empty 13, q A few do several right-s

The booth algorithm implements the multiplier

The booth algorithm takes full advantage of the importance of the complement, which allows us to reduce a lot of timing when we use the complement to calculate. The following table is an analysis of what we assume as a multiplier of 2. Next, I'll use the code to explain to you. 1, the beginning of the multiplier 2 of the ' negative one ' plus a default value of 0 00100 2, first judge [0:-1], the result is 2 ' b00, m
