Using smaller length improves the frequency of the mSGDMA,

The maximum transfer length is the maximum number of bytes transferred by each descriptor.

We do not have the comparison numbers and best values.

thank you for your valuable response.

"Using smaller length improves the frequency of the mSGDMA, "

I wish to understand a bit more about the above statement. Can you please elaborate?

just for my understanding...Increasing in frequency means increase in throughput? is that you mean?

what is actually confusing me is as you mentioned there is no transfer length comparison results available to compare the throughput .

please correct me if I am wrong.

    Hi,

    Increasing in frequency will result higher performance, not higher throughput.
