Hi
Can any body tell me, What type of data Vertex Data Master (VDM), Coarse Grain Scheduler (CGS), USSE are getting from Host CPU Interface. How we can program these interfaces. Can you please take an example & explain me. How we can program the Hardware Graphics Pipeline? Is it POWERVR SDK?
I tried all the possible we site, I didnt get anything.
Its very important for me as i am new to this.
Thanks
Braja

With a graphics API like OpenGL ES or OpenVG. Low-level interface specifications are not available to the public.
