Abstract :
The variable correction truncated multiplier is introduced. This is a method for minimizing the error of a truncated multiplier. The error is reduced by using information from the partial product bits of the column adjacent to the truncated LSB. This results in a complexity savings while introducing minimum distortion to the result.
