Design and Implementation of High Performance Parallel CRC Architecture for Advanced Data Communication

Abstract

Cyclic Redundancy Check (CRC) leverages to detect the error of digital data throughout generation, transmission, storage or processing. CRCs are widely used for being simple to execute in binary appliances, crafty to mathematical simulation as well as exclusively performance oriented at identifying generic deviation occured due to intrusion in communication channels. Commonly, hardware implementation of Cyclic Redundancy Check (CRC) computations rely on the Linear Feedback Shift Registers (LFSRs). LFSR framework processes bits serially that is one message bit per clock cycle but while considering high-speed data communications, serial implementation speed is significantly inadequate which causes delay. In this research, a hardware architecture is proposed for parallel computation. Its architecture is not polynomial dependent. After testing its functionality using ModelSim, it is implemented in Altera DE1 FPGA (Field Programmable Gate Array) board and analyzed using Quartus II, TimeQuest Timing Analyzer and Power Play Power Analyzer tools. It is found that the designed took 2771 LEs (Logical Elements), it has 102 pins and consumed 120.68 mW power. Functionality test and FPGA implementation showed that CRC was computed in single clock pulse of frequency of 23.71 MHz and its throughput is 1.656 Gbps. It can be configured for a different polynomial at any time externally. The focus of the research is to represent an efficient, better throughput along with compact systematic interpretation for parallel CRC hardware which will alleviate the flaws including the challenges of the existing CRC checker which will be prominent for next generation high speed communication.
