- * 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
- *
- * 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
- *
- * 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
- * polynomial $edb88320
