The hardware design supports the configuration parameters in the following table. These are set by the example application.
| Parameter | Description |
|---|---|
| Non-5G NR Control | |
| Code | Selects the LDPC code ID to be used or the turbo decode block size |
| 5G Control 1 | |
| z_j | Lifting factor |
| z_set | Base graph cyclic shift set |
| bg | Base graph |
| mb | Number of parity bits |
| sc_idx | Scale factor index, only available when the Normalized Min-Sum algorithm has been specified. |
| Common Control | |
| max_iter | Specifies the maximum decode iterations |
| term_on_pass | Specifies that decode should terminate on parity pass. |
| BER | |
| num_blocks | Specifies the number of codeblocks to run through the data path. |
| snr | Specifies the AWGN signal-to-noise ratio (SNR), -12dB to 16dB quantized to Fix17_11. |
| mod_type | Modulation type:
|
| zero_data | Specifies that the source data should be all zeros, rather than randomized data. Note, when the encoder instance has not been included in the design it always uses zero data. |
| skip_channel | Specifies that no channel noise should be applied. |
