本文提出一种通用的CRC 并行计算原理及实现方法,适于不同的CRC 生成多项式和不同并行度(如8

位、16 位、及32 位等) ,与目前已采用的查表法比较,不需要存放余数表的高速存储器,减少了时延,且可通过增加并

行度来降低高速数传系统的CRC 运算时钟频率.-In this paper, a universal principle of CRC and implementation of parallel computing methods for generating different CRC polynomial and different degree of parallelism (eg, 8, 16, and 32-bit, etc.), with the current look-up table method has been used in comparison do not store more than a few tables, high-speed memory, reducing latency, and degree of parallelism can be increased to reduce the high-speed data-transmission system clock frequency of the CRC computation.
