Hi all. Well, I know that CVI converts a generic input into an avalon st protocol compatibile data signal. Now, in my sistem i get a 27MHz pixel clock, while my video system is clocked @50MHz, a...

16 years agohi Niki, thanks a lot for your reply.
Yes, out from the CVI i have color planes in sequence. Then I add a color plane sequencer so in order to get two planes in parallel. I think I've understand. in sequence, only for video pakets, I have ...YcYcYcYcYcYc... but this is the flow for all the (720*240) pixels of my field, only when also datavalid is asserted. so I could count all pixels @50MHz clock. but what if they are transmit in parallel? I think they should be like this [15:8]YYYYYYYYYYYYY [7:0]ccccccccccccccc and they are transmitted only when datavalid is asserted(and i am in a video data paket sequence) .. they are still clocked @50MHz , isn't it?
