Which memory is better for the NIOS PROCESSOR?

Hi,

I'm using the DE1 kit,

my project includes a NIOS processor to present data on a color LCD...

I'm already using the SRAM for the LCD(to save the picture data on), so I need to decide which is better,

the SDRAM or the FLASh...I need fast timing...

thanks....

    SDRAM. Offen you use flash to hold video frames or images but before you display them you put them into an off-chip frame buffer. SDRAM works well for a frame buffer since a video engine and sequentially access it quickly. I don't know what resolution you are working with but if your SRAM is large enough to hold a couple frames you could use it as well.
