VVDN designed IP offloads CPU intense computation involved in LDPC Encode/Decodes. LDPC offload functionality IP has been developed inhouse with DPDK baseband device form library framework to provide workloads for offload. These DPDK Based API have been used for Transferring IQ sampled to and from Host.

The BBDEV driver will fill the corresponding descriptor ring and hardware accelerator that will submit the encode/decoded data in the dequeue ring after the respective operation. One core is provided for LDPC encode operation and three for decode.

User can submit the CB payload to the BBDEV driver after the CRC attachment.
