ABSTRACT

In this study, CRC error detection techniques will be used to not only identify but fix single-bit errors in digital communication systems. In the past, CRC codes have been employed mainly for their ability to detect errors efficiently. However, this paper suggests a new way that will make it possible to modify CRC functions and thus correct the identified errors. It is intended that by using an optimized look-up table in Verilog hardware description language with an advanced Xilinx 14.7 toolchain, this research can increase the dependability and effectiveness of error correction mechanisms found in digital systems. The study presents how to create a detailed hardware description, optimize lookup tables for minimal resource usage and increased error correction capability; then synthesizes design with Xilinx 14.7.The conclusion makes a practical contribution towards identification and removal of single-bit errors which indicates a turning point in the use of Cyclic Redundancy Check (CRC) technology from being just about error detection to full scale error correction. This enhancement has the potential to greatly increase the durability and reliability of data transmission and storage systems, especially in critical applications requiring utmost data integrity.
