At Computex 2010, AMD has demonstrated the Fusion Accelerated Processing Units (APUs) that combine CPU, GPU, video processing and other capabilities in a single die.

The APUs support DirectX 11 gaming and HD video content.

In a Fusion whitepaper, AMD has disclosed that its first APUs, code-named “Llano” and “Ontario,” are designed for mainstream desktop and notebook platforms, “thin and light” laptops, netbooks, and tablets. Both of these APUs will combine multiple superscalar x86 processor cores with an array of programmable SIMD engines leveraged from AMD’s discrete graphics portfolio.

“The key aspect to note is that all the major system elements – x86 cores, vector (SIMD) engines, and a Unified Video Decoder (UVD) for HD decoding tasks – atach directly to the same high speed bus, and thus to the main system memory. This design concept eliminates one of the fundamental constraints that limits the performance of traditional integrated graphics controlers (IGPs),” AMD says.

The launch of the AMD Fusion Family of APUs is planned for the first half of 2011.
