CRC32 API Overview
CRC32 API assists you in generating CRC32 checksums.
CRC32 checksums can be generated in two modes: accumulative and non-accumulative.
The accumulative mode is applied when the data for which the checksum is calculated (data) represents one or more continuous memory block(s) or when the data is created at runtime in many steps (for instance, when reading a file).
Non-accumulative mode can be applied when the data represents one continuous memory block, a null-terminated string, or a file.
To generate the checksum in the accumulative mode, perform the following:
Call the SL_FCRC32_Update function for each continuous memory block of data to perform the calculations.
Call the SL_FCRC32_Final function to obtain the checksum.
To generate the checksum in the non-accumulative mode, perform one of the following:
Call the SL_FCRC32_Calculate function if the data represents a continuous memory block.
Call the SL_FCRC32_CalculateStr function if the data represents a null-terminated string.
Call the SL_FCRC32_CalculateFile function if the data represents a file.
