Graphics Memory on Nokia Devices


i have a quite simple question, hoping someone of you has an answer to it:
Does Nokias S60 devices with PowerVR accelerator ( like N93, N95, N95 8GB ) its own graphics memory ( in hardware ) or are they sharing the memory with executables memory?

Best Regards,


They all use a unified memory architecture, RAM is shared between CPU and GPU.




Thank you for the answer.

But anyway, GL is doing a copy of vertex data, to gl server. Right?

So with unified memory architecture, will it help to load the arrays to VBOs, to reduce memory consumption?




It is generally a good idea to use VBOs for static vertex data. However you will not see much of a difference on devices with PowerVR MBX, even with UMA.
