Modified Booth Multiplier

1. MBE partial product array improves the speed performance at the LSB part.

Baugh Wooley

Algorithm:
 1. The most significant partial product of the first rows and the last row of partial products except the most significant have to be negated.
 2. A constant one is added to the column.
 3. The most significant bit (MSB) of the final result is negated.

Twin Precision

1. Twin precision multiplier that in a normal operation mode  efficiently performs N-bit multiplication.

2. The multiplier is  capable of performing two independent N/2 bit multiplication in parallel.

3. It has low power dissipation and higher speed than the conventional method.

Problem Statement

1. In  digital multiplier system, the bitwidth of the multiplier is required to execute a large operand of the application.

2. Drawbacks of bitwidth:
     a. Multiplier area is increased.
     b. High power dissipation.
     c. Long delay.
