The ultimate goal of communication system is to delivery information to the destination instantly and determinately. In practical systems tradeoff should be made between reliability and instantaneity. Algorithms for error detection and correction are widely employed in communication systems for reliability improvement. In this paper the CRC ( Cyclic Redundancy Check) algorithm is presented and analyzed in detail as well as its implementation in C and assembly.%通信的目的是把信息及时可靠地传送给对方,而在数字通信系统中可靠与快速往往是一对矛盾.为了提高通信可靠性,通信系统一般都采用了差错控制.本文详细介绍了循环冗余校验CRC( Cyclic Redundancy Check)的差错控制原理、算法分析,并给出了汇编程序和C语言程序实现.
