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 high-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).
