I'm doing a project that is about overlapping data transfer with computation on a CPU/GPU architecture. I have figured out how to do it on GPUs that have there own separate global memory. However I'm not sure if a similar approach can be taken to speed up AMD Fusion architectures. As far as I can tell there is no separate global memory to speak of, so I'm guessing it falls outside of the scope of my project, but I'd like to see a clear document that describes whether this is relevant for my project or not. Does anyone know where to find this?
Also there are supposed to be GPUs that are integrated directly into the motherboard. What are those called and do those have separate global memory?
