Nowadays people are using Electronic Systems widely in their daily life. Without any Electronic product, there is no life for human beings on Earth now. The requirements of the present generation of people are high Speed, low Power and low Area Electronic Systems. A number of arithmetic circuits are used in Digital Systems. Different arithmetic circuits are Adder, Multiplier, Divider etc. There are different multipliers with different techniques to obtain Products from Multiplier and Multiplicand.Radix-4 Multiplier is one of the Multiplier. In the Radix-4 Multiplier number of Partial products is n/2, where n is the number of bits of Multiplier. Speed of operation, Power dissipation and area of this Multiplier are high. By decreasing the number of Partial products of n-bit Multiplier, Area, Power Dissipation and Propagation Dely can be decreased. In Radix-8 n-bit Multiplier number of Partial Products are n/3.This decreases the Area, Delay and Power Dissipation. Radix-4 & Radix-8 Booth 8-bit Booth Multipliers are designed and Implemented on FPGA. Delay, Power Dissipation and Area are compared for both Multipliers. The comparison indicates that Radix-8 Booth Multiplier is best Compared to Radix-4 Booth Multiplier with respect to Delay, Power Dissipation and Area. So, we can replace Radix-4 Booth Multiplier with Radix-8 Booth Multiplier. Problem definition: Nowadays, there are many Electronic Systems used by people for different purposes. They may have different Subsystems in them which may have low Speed, high Area and high-power Dissipation. Multipliers are used in a number of applications like Digital Filters, Multimedia etc. Radix-4 is such a multiplier. The drawback of Radix-4 Booth Multiplier is number of Partial Products is n/2 where n is the number of bits of Multiplier. This leads to high Delay, Power Dissipation and Area. They can be decreased by decreasing the number of Partial Products. In the Radix-8 Booth Multiplier, the number of Partial Products is n/3. the complexity of radix-4 multipliers can lead to challenging signal routing on integrated circuits,
