ImgTec Launches Programmable Shader Graphics Family

[Lazy8s]

The new description now further specifies that the shading engine makes workloads into processing packets which are executed across the multithreaded processing units and is assisted by co-processors, illustrated in a streamlined diagram with some new terminology.

The old block diagram presented the layout in a slightly different way.

Yes, Falanx does seem like a sneaky sort of a company to me.

Don't believe what comes out of their mouths I say.

And yet, no explanation why...

Is SGX's video processing capable of encoding and decoding H.264 at 30-fps?

 

[Shifty Geezer]

Surely yes, given you haven't specified a resolution. H.264 at 6x4 pixel resolution is doable.

Well heck, he didn't even specify an FPS target, so surely 640x480 at 0.00000001 fps is doable too!

You might want to check that Ty

Doh!

The question is whether the 30-fps at its typical target resolutions of encoding and decoding can be done concurrently, useful for video teleconference.

Actually I don't think that is the question at all. Videoconferencing in handhelds is almost always low resolution (due to bitrate limitations), so the implementation is a little more trivial.

The key question is what frame size/rate can they handle, and more importantly, what memory bandwidth does the architecture require while doing it? And how much power?
