15fps to 60fps video conversion

Thank you for the reply.

In the user guide for the board, it states that the on-board SDRAM maximum frequency is approximately 125MHz.

It is a Cyclone IVE board, with two IS42S16320B-7TL SDRAM modules connected in parallel so the effective data width is 32 bits.

Datasheet for the component states the maximum frequency is 143MHz.

Referring to your advices:

- now the entire system runs on 133MHz, with SDRAM clock being phase shifted for -65 degrees.

- Frame Buffer Avalon-MM master port matches the SDRAM port width, being 32.

- I increased both the Frame Buffer burst target and FIFO depth to maximum values available in the GUI

- I increased the Clocked Video Output embedded FIFO depth to be twice a line length (app 4k)

I see no progress with these.
