Power management refers to the techniques that carefully manages the overall performance of a system to achieve low power goals. The technique that using for power management should ensure that the overall power, by using both hardware and software, should not lead to the unnecessary power dissipation. Since system designs are becoming complex day by day, the need for power management plays a vital role in every design. In digital electronics, a multiplier is an important arithmetic circuit that performs the mathematical operation of multiplication. It is a fundamental component for designing various digital designs, such as microprocessors, digital signal processors, and arithmetic logic units, to perform complex calculation when necessary. Multipliers are designed to compute the product of two binary numbers efficiently and accurately, which can represent various forms of data, including integers, floating-point numbers, and fixed-point numbers. The primary function of a multiplier is to take two binary inputs, typically represented as sequences of O's and 1's, and generate a binary output that represents their product. This operation involves a sequence of binary additions and shifts, as multiplication essentially amounts to repeated addition and shifting of partial products. The main drawback of this multiplier circuits are complexity and they occupy more area in any design. To figure out the problem, approximate multiplier has used. Approximate multiplier eliminate the redundant portion of multiplier which results in reduction in overall power consumption and area. This is done with the help of static segmentation, where partial product of the multiplier is divided into smaller segments for easier computation.
