unfortunately the data still has to be in a full 32BPP framebuffer (in order for 2D or 3D Window Managers to write to it).

all the graphics software will write at that full 32BPP rate: it is unfortunately not reasonable to expect all Graphics Software to perform data compression.

yes there will be a few opportunities for compressed streaming, and funnily enough we were just thinking "what if the GPU were to do the same trick as the Amiga used to do, 40 years ago, by following the scan-lines?"

in the case of video playback you might reasonably expect that an area of the screen is "reserved" (not written to) but that when the Video-Output HDL gets to that pixel instead reads directly from a completely different device: one that is formatted already in HDR/SDR or YUV.

effectively this is a modern "sprite" engine.

... but, again, we have significantly diverged from the original "Just Make It Real Simple Why Don't You Just", yeh? :)
