An energy-efficient and fast approximate multiplier is presented in this study. Operands are rounded up to the next exponent of two, which is what we're going for here. At the cost of a little inaccuracy, the computationally costly part of the multiplier is removed, which improves both speed and energy consumption. Multiplications that are signed or unsigned can both benefit from the new method. One for unsigned operations and two for signed operations are included in our three implementations of the approximation multiplier. Performance comparisons are carried out utilising different design parameters for the suggested multiplier in order to evaluate its efficiency. It is also examined in terms of image processing applications, such as sharpening and smoothing of images. In order to expand The RoBA multiplier is utilised in the FIR Filter convolution process.
