说明：  循环冗余码校验（CRC）是一种可靠性很高的串行数据校验方法。介质循环冗余码校验的基本原理，并分别用单片机和CPLD作了循环冗余码验的软件实现和硬件实现。包括汇编语言和VHDL语言源程序
(Cyclical redundancy check (CRC) is a high reliability of the serial data validation methods. Media cyclical redundancy check of the basic principles, and were made with MCU and CPLD Cyclic Redundancy Code inspection software and hardware realize realize. Including assembly language and VHDL language source)
