Can FrameBuffer be connected to onchip-FIFO,and then to SGDMA?

Hello,now I design a custom board using cyclone IV EP4CGX15 to transfer video to our SOC. And now there is no on-board external RAM connected to FPGA,so I have to use on-chip memory. For ...

Socrates,Thank you very much!

Sorry for I'm so newbie in FPGA,I'm not quite clear about your meanings.

I think I didn't express our applications pretty clear.

We want to use FPGA to act as a Bridge which sends raw video data to out SOC through PCIe.

And use SGDMA to send video data to PCIe IP provided by altera.

You mean that I should use a dual-port RAM?

Just like "FrameBuffer--> DualPort RAM--->SGDMA“?

Regards!
