2017-08-16 Cyclic Redundancy Codes (CRCs) are among the best checksums available to detect and/or correct errors in communications transmissions. Unfortunately, the modulo-2 arithmetic used to compute CRCs doesn't map easily into software. This article shows how to implement an efficient CRC in C or C++.

However, sometimes you must compute a CRC in software, for example in a C or C++ program that will run in an embedded system. CRC A cyclic redundancy code (CRC) is a powerful type of checksum that is able to detect corruption of data that is stored in and/or transmitted between embedded systems. Generally speaking, CRCs are most efficiently calculated in dedicated hardware. However, sometimes you must compute a CRC in software, for example in a C or C++ program that will run on a microcontroller.

Note that we can't use Intel's CRC32 SSE instruction as that uses the Castagnoli polynomial (CRC32-C), not the "regular zip" poly.
