SQUARE ROOT ARCHITECTURE:
Square Root architecture following the methodology given in Step-1 to Step-6, consists of four sub sections: - (1) Nearest Square Root Generation Unit (NSRGU) for first N/2 numbers, (2) Squaring Unit, (3) Subtractor , (4) Divider.
Fig.-2 exhibits a fully optimized system level architecture for square root generation using Duplex method adopted by ancient Indian mathematicians. In this architecture all the left shifters are N/4 bit left shifters. Quotient register is used to store the fixed point or integral result of the square root. The most significant two bits fed to the doublers whose output is fed to the subtraction unit.
