AMD Fusion System Architecture Detailed

Vigile writes "At the first AMD Fusion Developer Summit near Seattle this week, AMD revealed quite a bit of information about its next-generation GPU architecture and the eventual goals it has for the CPU/GPU combinations known as APUs. The company is finally moving away from a VLIW architecture and instead is integrating a vector+scalar design that allows for higher utilization of compute units and easier hardware scheduling. AMD laid out a 3-year plan to offer features like unified address space and fully coherent memory for the CPU and GPU that have the potential to dramatically alter current programming models. We will start seeing these features in GPUs released later in 2011."
