Abstract: Most commonly used operation in many electronic and computing systems is multiplication operation. In order to meet the challenges that occur from advanced technology low power consumption is one of the important features in order to meet the various applications. Among the arithmetic operations the multiplication is one of the important operation that act as a basic operation to be used in every circuit to get efficient than other operations. Out the different types of multipliers the booth multiplier is one of the standard technique that allows a smaller, circuits to operate with fast and quick multiplication by using encoding techniques to the signed numbers of 2’s complement. This standard technique is mostly used for the designing of the chip for any application and then provide improvements that are required to reduce the number of the partial products to half. The “Complex multiplication” techniques. In this way the booth multiplier can be able to reduce the number of iteration steps for performing the multiplication. When we consider the number of partial products of other conventional multiplier the booth multiplier can get less number of partial products. The main goal of any VLSI projects is to perform operations with high speed, low power consumption and also less area. Among the three features the speed is one of the most important factor that plays a vital role for every application. So, if we consider the process of algorithm for booth multiplier it generally consists of two basic steps which are generation and addition of partial products. The multiplier speed depends on the fastness of the partial products generated and how fast the addition is done by the multiplier. In this paper different techniques and algorithms are used for the design of the booth multiplier in order to get less consumption and less area to be consumed. Also focused on the improvement of speed of the multiplier and to reduce the delay.
