Hi Daixiwen,

Thank you for responding

Both sources support back-pressure and the Frame Buffer is a passive component so it delivers data whenever the READY signal is asserted (otherwise it stalls). So I'm using an SCFIFO for the scaler sources and I'm trying to read it when the READY signal from the output and the VALID signal from the frame buffer are asserted ! But I still get a delayed data !

Can I manage to control both sources without using a FIFO ?

Do you have any example on how to stall a stream to a startofpacket of another stream ?

thank you
