The Application Programming Interface (API) of the C model is defined in the header file sd_fec_v1_1_bitacc_cmodel.h. The interface consists of a specification file, data structures, and functions as described in the following sections.
An example C file, run_bitacc_cmodel.c, is included with the C libraries. This file demonstrates how to call the C model. The run_bitacc_cmodel.c and run_sd_fec_v1_1_bitacc_mex.m contain example code for the LDPC encoder and decoder and turbo decoder to show the basic operation of the C model.
