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

What is the resolution and bit depth of the video you want to frame buffer?

Do you want a double or triple buffer?

You will almost certainly not have enough on-board memory if you have video of any

significant size.

For instance, to triple buffer color video at VGA resolution, you would need a minimum of

24 (bits per pixel) * 640 (columns) * 480 (rows) * 3 (buffers) = 21,600 Kbits

of embedded memory, which not even the largest Cyclone V devices are supporting.

You will almost certainly need an external SDRAM or SRAM in order to frame buffer your video.

I'd offer to download framebuffer demo from alterawiki.com :)
