4.1.3. 5G LDPC IP Decoder Parameters

Table 19.  Decoder Parameters
Parameter Value Description
IN_WIDTH 5 or 6 (default value is 6) The number of bits per input LLR. The width of sink_data is (64 * IN_WIDTH).
NUM_DECODERS 1 or 2

The number of decoders in the IP
MAX_LF_DECODER0 96, 128, 192 or 384

The maximum lifting factor for the packet that the first decoder can handle.

When NUM_DECODERS is 1, all four options are valid

When NUM_DECODERS is 2, only 384 is valid.

MAX_LF_DECODER1 96, 128 or 192

The maximum lifting factor for the packet that the second decoder can handle.

Only for NUM_DECODERS=2.
