High Performance Novel Square Root Architecture Using Ancient Indian Mathematics for High Speed Signal Processing

Advances in Pure Mathematics 2015年第8期5卷 428-441页

作者： Arindam Banerjee Aniruddha Ghosh mainuck das Department of ECE JIS College of Engineering Kalyani India

Novel high speed energy efficient square root architecture has been reported in this paper. In this architecture, we have blended ancient Indian Vedic mathematics and Bakhshali mathematics to achieve a significant amount of accuracy in performing the square root operation. Basically, Vedic Duplex method and iterative division method reported in Bakhshali Manuscript have been utilized for that computation. The proposed technique has been compared with the well known Newton-Raphson’s (N-R) technique for square root computation. The algorithm has been implemented and tested using Modelsim simulator, and performance parameters such as the number of lookup tables, propagation delay and power consumption have been estimated using Xilinx ISE simulator. The functionality of the circuitry has been checked using Xilinx Virtex-5 FPGA board.

In this paper,focus has been given to design and implement signed binary subtraction in quantum *** the type of operand may be positive or negative,therefore a novel algorithm has been developed to detect the type of operand and as per the selection of the type of operands,separate design techniques have been developed to make the circuit compact and work very *** separate methods have been shown in the paper to perform the signed *** results show promising for the second method in respect of ancillary input count and garbage output count but at the cost of quantum cost.
