intel vRAN ACC100 -------------- DPDK

[MB_6778]

Hello,

We are working on the Intel vRAN ACC100 PCIe card, and I have some technical questions about driving this card for turbo coding and decoding as a solution in 4G cellular systems. We are using DPDK in the Ubuntu 20.04 environment and have also used test-vectors to validate the processing of this card. However, we are now experiencing a problem with the shape of the data that we should insert into the card to perform operations like turbo decoding. Our problem is that when we use example data in MATLAB, we cannot get output results matching those in the example data files provided by DPDK. Now, I would like to request a document or a helpful link that explains what shape of data we should insert into the ACC100 as input in both decoding and encoding states. Thank you.

I have attached the inputs and outputs provided as examples in the DPDK documentation. We have converted the inputs and outputs to bit streams and then inserted them into MATLAB for encoding, but the results are not the same. Additionally, we have obtained the outputs from the validation part of the DPDK, which provides tests in two separate states: the output after rate matching and before rate matching. I have also attached these outputs in the file, marked by a '#' symbol at the beginning of each.

hello Michael L.
still now, I do not get any useful link or answer about my problem in that was "shape and kind of the input for turbo coding or decoding t  using the intel vRAN ACC100" please help me or better tell me i should search or ask my question in which forum.
thanks, best
