Application Specific Integrated Circuit Implementation of Various Linear Feedback Shift Register Models

Abstract

In many electronic devices, linear feedback shift register (LFSR) is used for generating pseudo-random numbers, pseudo-noise sequences and fast digital counters. So for high performance applications LFSR should generate efficient sequences. The efficient sequences can be generated in so many methods. The aim of the paper is to compare  various LFSR implementations in the standard polynomials. The practical guidelines to choose the optimum LFSR design for pseudo-random generator was provided. The comparison of various LFSR implementations in different polynomial was analyzed. The design was simulated and synthesized using synopsys verilog compiler simulator and cadence register transfer language compiler and cadence encounter tool was used for application specific integrated circuit implementation. On comparing with different LFSR implementation, the Fibonacci model offer significant advantage in terms of minimum power and area.
