In this paper, the authors have done an extension of work using Spartan-3 FPGA family. Power dissipation is an important factor to be taken into consideration. Simulations are done using Spartan-6 and because of its good features and it's capability of having 42% less power consumption and 12% increased performance over previous generation devices. Arithmetic and Logic Unit (ALU) is being implemented which has a capability of doing arithmetic and logical operation along with calculation of Greatest Common Divisor (GCD) using Euclid's and Stein's algorithm.
