  * string prarm name, see table 9-1 for details of the parameter model name When this parameter is passed in, the default table parameters are used and the poly,init,xorout,refin,and refout passed in are invalid.
  * number prarm.width: the width, i.e. the number of CRC bits.
--* number [prarm.poly]: short for the generated item, in hexadecimal notation. For example, CRC-32 is 0x04C11DB7, ignoring the highest bit "1", i.e., the complete generation item is 0x104C11DB7.
--* number [prarm.init], the initialization preset value of the register (crc) at the beginning of the algorithm.

++* number [prarm.xorout]: the final CRC value obtained after heterodyning the calculation result with this parameter.
++* number [prarm.refin]: whether each byte of the data to be measured is inverted by bit, true or false.
