An approximate multiplier that is high speed yet energy efficient. The approach is to round the operands to the nearest exponent of two. This way the partial product used in regular multiplier was replaced by the shifters. Computational intensive part of the multiplication is omitted improving speed and energy consumption at the price of a small error. The approach is applicable to both signed and unsigned multiplications. The delay even can be reduced by replacing the adder with the Han-Carlson adder (HCA) .In addition, the efficiency of the approximate multiplier is studied in two image Processing applications, i.e., image sharpening and smoothing. The existing and proposed multiplier is designing using Xilinx 14.7 in the frontend. The speed of proposed multiplier 4% increase compare to proposed multiplier.

ROBA, HCA and Xilinx.
