A possibility could be the Xscale and intel 2700:
http://en.wikipedia.org/wiki/Intel_2700G which supports OpenGL ES.
Isn't an X-Scale just a fast ARM?
yeah, but the 2700 has an Xscale coprocessor interface, which means
it needs to have an Xscale
(or, I suppose, FPGA) to talk to.
If you find the datasheet for the 2700g, I would like to see it -
intel appears to have removed it from their
site.
Also, this information might be useful to us: The 2700G performs
Inverse Zig-Zag, Inverse Discrete Cosine Transform, and Motion
Compensation to speed up MPEG-1, MPEG-2, MPEG-4 and WMV video
decoding. The accelerator can decode MPEG-1, 2 and WMV at 720x480
(DVD Resolution) and MPEG-4 at 640x480, both at over 30 frames per
second.
These all run at 75 Mhz
75 MHz seems a bit slow. :-D
That was my point - we will (hopefully) be able to run faster than
that, which means we can get higher
performance.
- It is likely that we will be able to decode slightly better than
this if we implement those features. Given the R&D intel must have
put into this chip, that is probably where 99% of the CPU power goes.
I think that chips intended to make a set-top box might be usable
for a medium price video card which could also decode h.264 HiP
1080p/30 -- it would also include a sound card.
Yeah, one of those ARM/DSP hybrids (Atmel makes one) could easily do
it. I am not sure of the
OpenGL performance, but that DSP has a few GFLOPS of performance.
