说明：  本代码为查表法CRC16和CRC32校验的表生成和校验程序。使用此代码可以任意多项式生成CRC16和CRC32的程序。另有文件实现CRC16和CRC32的校验。 使用生成的表格，即可以在嵌入式中实现RAM和ROM区的校验。源程序在MSP430上实现，现整理成通用C版本。
(the code look-up table method CYXLIC REDUNDANCY CRC checksum and the table generation and checking procedures. Use this code can be generated CYXLIC REDUNDANCY arbitrary polynomials and CRC procedures. Another document CYXLIC REDUNDANCY and achieve the CRC checksum. Use generated forms, which can achieve the embedded RAM and ROM of checking. Source achieve the MSP430 is organized into common C version.)
