so does the OpenGL ES rely on a specific hardware abstraction
interface in order to reach the hardware accelerations?
yes.
Do I have to implement a .so library, like for copybit, in order to
map 3D graphics, vector graphics, ...to the GPU hardware functions?
it is not necessary , but is a better way I think.
Thanks!

actually, you do not have to implement copybit , but this module
can accelerate your graphic application. e.g, color space convert,
image stretch etc.
and i should tell you the PXA310 has no GPU on it.
how to implement egl in hardware? I think you may use the
Wireless MMX technology to optimize the egl library in android,
maybe or not., I don't know for sure.
Because the GPU hardware we called it should have these features
at least:
3D graphics, vector graphics,
shader, scalable,
OGL-ES 1.1 and 2.0, Open VG 1.1,
Cube map texture, projected texture, non-square texture etc.

the CPU is a PXA310 by Marvell, I know I could build the copybit
library starting from the WMMX2 graphical technology
I actually do not know if this CPU has a GPU
could you give me some tips on how to implement the elg in
hardware? what is the hw requirement for?

yes ofcourse no need, but the android will become such slowly
without it.
instead of it , it will load the software egl library.
I want to know how is your ARMv5 running quite well without GPU?
can launcher be smoothly with only ARMv5? or something like
3D game else?

Hi All,
I have intention to port ICS to an ARMv5 processor based
platform where Android 2.3.7 (gingerbread) is running
quite well.
So I am wondering if the porting of Android 4.x to this
platform is an impossible mission because my hardware
does not include a graphical processor unit or any
specific graphical hardware acceleration except the WMMX2
(wireless multi-media accelerations for Intel/Marvel
xscale platform)
Is this true or no?
thanks all!
Marco
