HI All, I am working on MSC8156-AMC board. In TVPE Mpale there is one function "void maple_driver_load(maple_dev_init_params_t *maple_param)" Which load turbo interleaver table and then TVPE does furthur processing. My query is can I use/rewrite same thing for TurboEncode Interleaving?

8156 MAPLE-B support Turbo and Vertibe decoding, but it doesn't support Turbo encoding.

We have 8157 MAPLE-B2 which supports Turbo encoding.

The TVPE in MAPLE-B includes Interleaver initialization registers which are required to be initialize depending on the interleaving type ( normal CTC, inversed or Sub-block interleaving), and block size.

The table you are referring to hold these initialization values used by the firmware to initialize the registers according to the required interleaving type and size.
