Detailed Description¶
Operation structure for LDPC encode. An operation can be performed on one CB at a time 'CB-mode'. An operation can be performed on one or multiple CBs that logically belong to a TB 'TB-mode'.
The input data is the CB or TB input to the decoder.
The output data is the ratematched CB or TB data, or the output after bit-selection if RTE_BBDEV_LDPC_INTERLEAVER_BYPASS is set.
The output mbuf data structure is expected to be allocated by the application with enough room for the output data.
