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.

Do I have to implement copybit?
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
