WebTo run a stand-alone test of the reference implementation of CRC computation, follow these steps: Create a CCS project with an empty main.c file. Copy the contents of example_c1.c ( Example C-1) to the main.c file. Create a crc_tbl.h file in the project, and copy the contents of Example 8-29 to that file. Build and test the project. WebJul 30, 2024 · Algorithm for Encoding using CRC. The communicating parties agrees upon the size of message, M (x) and the generator polynomial, G (x). If r is the order of G (x), r, bits are appended to the low order end of M (x). This makes the block size bits, the value of which is xrM (x). The block xrM (x) is divided by G (x) using modulo 2 division.
