Research and Analysis of CRC Checksum Algorithm Based on FPGA

The term Cyclic Redundancy Check (CRC) refers to a type of checksum algorithm used in data communication protocols to detect errors in data transmission. CRC check code can be generated and added to the transmitted message, allowing the receiver to verify the integrity of the data. This technique has become widely used in digital communication systems and networks to ensure the accuracy and reliability of data transmission. The CRC8 encoder is a digital circuit that performs error detection during data transmission. A simulation was conducted to verify its functionality, comparing output data with expected values. The results confirmed the circuit's effectiveness in accurately detecting errors and generating CRC8 values. It plays a vital role in ensuring data integrity. In conclusion, CRC is a widely used error detection algorithm with strengths and limitations in data transmission and storage systems. Ongoing research aims to enhance its efficiency and accuracy for more reliable data integrity.
