However, sometimes you must compute a CRC in software, for example in a C or C++ program that will run on a microcontroller. To save yourself time as The crc32 () function helps us to calculate a 32-bit crc or cyclic redundancy checksum polynomial for a string. The function uses the CRC32 algorithm.This function can be used to validate data integrity. C.3 Linker-Generated Copy Tables and CRC Tables.

C.3 Linker-Generated Copy Tables and CRC Tables. Three tasks exist in separate load areas. As each is needed, it is copied into the common run area and executed. A separate copy table is generated for each task (see table() operator in ex1.cmd). CRC values for the task functions are verified as well.

The crc32() function generates a 32-bit cyclic redundancy code (CRC) for a string. The function is generally used to validate the integrity of data being transmitted.
