Abstract:

This paper analyzes the algorithm for and implementation principle of CRC key technology.Implementation of the generative polynomial suited to the bus protocol CRC generator and CRC checker with a hardware circuit is proposed.By this method,the CRC generator and CRC checker verilog code we programmed by the SATA international standards are verified by the vcs simulator and integrated to the SATA bus successfully and SATA communication is therefore achieved.The scheme of the CRC generator and CRC checker has the advantages of high reliability and great practicality and that it can improve the rate of project development.
