That would be awesome. Don't need right away though.
Another question is PSRAM bandwidth. Think seeing that exVGA is pulling video from PSRAM one line at a time.
Would one be correct in presuming that since this can work with PSRAM4, that with PSRAM16 there would be plenty of bandwidth for other cogs to be pulling/pushing lines at the same time?
At 320x240 16bpp it's not a bother, no. Pushing a full frame up is <1ms for 16 bit (Note that this is at 250Mhz and with plenty of overhead left on the PSRAM driver side), something like 1.6ms for 8bit. 4 bit gets a bit bad then (though probably still ok if not trying for the 60 FPS tour de force)
