Booth's multiplication algorithm multiplies two signed binary numbers in two's complement notation. It was invented by Andrew Donald Booth in 1950.

It shifts the partial product and multiplier arithmeticly to the right after each step to inspect the next bits.

Shift microoperations are used to serially transfer data and are used with arithmetic, logical, and other data processing units. There are three types of shifts: 1) logical shifts transfer zeros into the shifted bits, 2) circular shifts circulate bits around the two ends of the register, and 3) arithmetic shifts preserve the sign bit during a right shift and insert zeros during a left shift, changing the sign if overflow occurs.
