/**********************************************************************\
|* Demonstration program to compute the 32-bit CRC used as the frame *|
|* check sequence in ADCCP (ANSI X3.66, also known as FIPS PUB 71 *|
|* and FED-STD-1003, the U.S. versions of CCITT's X.25 link-level *|
|* protocol). The 32-bit FCS was added via the Federal Register, *|
|* 1 June 1982, p.23798. I presume but don't know for certain that *|
|* this polynomial is or will be included in CCITT V.41, which *|
|* defines the 16-bit CRC (often called CRC-CCITT) polynomial. FIPS *|
|* PUB 78 says that the 32-bit FCS reduces otherwise undetected *|
|* errors by a factor of 10^-5 over 16-bit FCS. *|

typedef uint32_t UNS_32_BITS;
/* Copyright (C) 1986 Gary S. Brown. You may use this program, or
code or tables extracted from it, as desired without restriction.*/
/* First, the polynomial itself and its table of feedback terms. The */
/* polynomial is */
/* X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0 */
/* Note that we take it "backwards" and put the highest-order term in */
/* the lowest-order bit. The X^32 term is "implied"; the LSB is the */
/* X^31 term, etc. The X^0 term (usually shown as "+1") results in */
/* the MSB being 1. */
/* Note that the usual hardware shift register implementation, which */
/* is what we're using (we're merely optimizing it by doing eight-bit */
/* chunks at a time) shifts bits into the lowest-order term. In our */
/* implementation, that means shifting towards the right. Why do we */
/* do it this way? Because the calculated CRC must be transmitted in */
/* order from highest-order term to lowest-order term. UARTs transmit */
/* characters in order from LSB to MSB. By storing the CRC this way, */
/* we hand it to the UART in the order low-byte to high-byte; the UART */
/* sends each low-bit to hight-bit; and the result is transmission bit */
/* by bit from highest- to lowest-order term without requiring any bit */
/* shuffling on our part. Reception works similarly. */
/* The feedback terms table consists of 256, 32-bit entries. Notes: */
/* */
/* 1. The table can be generated at runtime if desired; code to do so */
/* is shown later. It might not be obvious, but the feedback */
/* terms simply represent the results of eight shift/xor opera- */
/* tions for all combinations of data and CRC register values. */
/* */
/* 2. The CRC accumulation logic is the same for all CRC polynomials, */
/* be they sixteen or thirty-two bits wide. You simply choose the */
/* appropriate table. Alternatively, because the table can be */
/* generated at runtime, you can start by generating the table for */
/* the polynomial in question and use exactly the same "updcrc", */
/* if your application needn't simultaneously handle two CRC */
/* polynomials. (Note, however, that XMODEM is strange.) */
/* */
/* 3. For 16-bit CRCs, the table entries need be only 16 bits wide; */
/* of course, 32-bit entries work OK if the high 16 bits are zero. */
/* */
/* 4. The values must be right-shifted by eight bits by the "updcrc" */
/* logic; the shift must be unsigned (bring in zeroes). On some */
/* hardware you could probably optimize the shift in assembler by */
/* using byte-swap instructions. */
