In the Frame Buffer GUI, there is a place to set read and write FIFO depths and burst target. The UG doesn't specifically call out if these numbers represent "bits", "bytes", "pixels", whatever. Does anyone know? I sort of believe it's defined in pixels so if you set your "bits per pixel" to 8, these numbers would be bytes. Sound reasonable?

I believe they are in units of Avalon-MM bus width (words).

e.g. 64-bit bus width and 64 burst target would transfer 512 8-bit pixels per burst.
