Algorithm 2: “C” Bit Shift Implementation

This algorithm was mainly written to avoid any possible legal issues about the source of the routine (at the request of the

LCDproc group). This routine was “clean” coded from the definition of the CRC. It is ostensibly smaller than the table

driven approach but will take longer to execute. This routine is offered under the GPL.

typedef unsigned char ubyte;

typedef unsigned short word;

word get_crc(ubyte *bufptr,word len)

{

newCRC;

//Put the current byte in here.

ubyte

data;

int

bit_count;

//This seed makes the output of this shift based algorithm match

//the table based algorithm. The center 16 bits of the 32-bit

//"newCRC" are used for the CRC. The MSb of the lower byte is used

//to see what bit was shifted out of the center 16 bit CRC

//accumulator ("carry flag analog");

newCRC=0x00F32100;

while(len--)

{

//Get the next byte in the stream.

data=*bufptr++;
