A power-aware signed 2-dimensional bypassing multiplier for video/image processing

This paper presents a power-aware signed digital multiplier design by taking advantage of a 2-dimensional bypassing method dedicated for local multiplications widely used in FFT/IFFT operations of video/image processing. The proposed low power multiplier is carried out by Baugh-Wooley algorithm using novel 2-dimensional bypassing cells. The proposed bypassing cells constituting the multiplier skip redundant signal transitions when the horizontally (row) partial product or the vertically (column) operand is zero.
