Hello,
in my Project i have to implement Camera stream encryption.
In the current design contains a 128 bit Key/block modul.
the delay is between 12 and 21 tacts , depend on AES Implementation, and this delay causes a distortion.
My question is, what i have to consider or change in the zynqberry demo 1 To compensate the delay?
Regards
Stefan
Hello,
At which part of video datastream are you insert your encription core ?
As first step you can try to add FIFOs before and after your core it can help.

Hello Oleksandr,
my core is between video_resize and the VDMA.
I verify the data order with the ILA, this seeems not the problem. I control the data stream by the signals s_tready, m_tvalid and pass the signals s_tuser , t_last.
in the attachments is a image how the destortion look like.
Best Regardes ,
Stefan
