In this paper, we tend to propose an approximate multiplier that's high speed yet energy efficient. The approach is to round the operands to the closest exponent of 2. This manner the procedure intensive a part of the multiplication is omitted up speed and energy consumption at the worth of little error. The proposed approach is applicable to each signed and unsigned multiplications. We tend topropose three hardware implementations of the approximate multiplier that features one for the unsigned and 2 for the signed operations. The efficiency of the proposed multiplier is evaluated by examining its performance with those of some approximate and exact multipliers using totally different style parameters. Additionally, the efficiency of the proposed approximate multiplier is studied in two image process applications, i.e., image sharpening and smoothing.
