How CPUs With Integrated Graphic Manage The System Memory?

[bahr]

Hi Guys!

I'm Bahr, and lately i've been reading several articles about CPU with built in IGP such as Intel Pineview, and AMD Llano (fusion). But something still puzzled me, how these system managed the system memory?

Is it like today's IGP where they take some of the system memory to be used as graphic memory? Is it using somekind of Sideport Memory? Or, is it something new?

Maybe some of you have info on this, and links to it would be appreciated. Thank You.

It is like today's IGP, it uses system memory

Initially it's likely to just use the system memory, but later they may (hopefully) improve it.
