The main objective of this project in order to propose 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 machine intensive a part of the multiplication is omitted up speed and energy consumption. The potency of the planned multiplier factor is evaluated by comparing its performance with those of some approximate and correct multipliers using different design parameters. The proposed approach is applicable to both signed and unsigned multiplications. We propose three hardware implementations of the approximate multiplier that includes one for the unsigned and two for the signed operations. The approach is applicable to both signed and unsigned multiplications. We propose three hardware implementations of the approximate multiplier that includes one for the unsigned and two for the signed operations. To achieve imprecise multiplication, simple addition and shift operations are performed using rounded and original input operands. Approximate multipliers have better performance in terms of speed, power, and area compared to exact multipliers. The parameters of RoBA multiplier which can be used in the voice or image smoothing applications in the DSP. For extension in the convolution process of the FIR Filter RoBA multiplier is used.
