X First,the polynomial itself and its table of feedback terms. The
X polynomial is:
X
X 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
X
X Note that we take it "backwards" and put the highest-order term in the
X lowest-order bit. The X^32 term is "implied"; the LSB is the X^31
X term,etc. The X^0 term (usually shown as "+1") results in the MSB being
X 1. Note that the usual hardware shift register implementation,which is
X what we're using (we're merely optimizing it by doing eight-bit chunks at
X a time) shifts bits into the lowest-order term. In our
X implementation,that means shifting towards the right. Why do we do it
X this way? Because the calculated CRC must be transmitted in order from
X highest-order term to lowest-order term. UARTs transmit characters in
X order from LSB to MSB. By storing the CRC this way, we hand it to the
X UART in the order low-byte to high-byte; the UART sends each low-bit to
X hight-bit; and the result is transmission bit by bit from highest- to
X lowest-order term without requiring any bit shuffling on our part.
X Reception works similarly.
X
X The feedback terms table consists of 256 32-bit entries. Notes:
X
X The macro for using the table is UPDC32 is located in zmodem.h
X
X It might not be obvious,but the feedback terms simply represent the
X results of eight shift/xor opera- tions for all combinations of data
X and CRC register values.
X
X The values must be right-shifted by eight bits by the "UPDC32" logic;
X the shift must be unsigned (bring in zeroes). On some hardware you
X could probably optimize the shift in assembler by using byte-swap
X instructions.
