Rivals AMD and ARM unite, summon others to become 'heterogeneous'Rumors of a hook-up between AMD and ARM have been circulating ever since someone coined the phrase "the enemy of Intel is my friend." As of today, however, that alliance is real and cemented in the form of the HSA Foundation -- a non-profit organization dedicated to promoting the dark arts of Heterogeneous System Architecture. It's a relatively old concept in computing, but the Foundation's founding partners (AMD, ARM, Imagination Technologies, MediaTek and Texas Instruments) all stand to gain from its wider adoption. How come? Because it involves boosting a chip's performance by making it use its various components as co-processors, rather than treating them as specialized units that can never help each other out.

In other words, while Intel pursues Moore's Law and packs ever-more sophisticated transistors into its CPUs, AMD, ARM and the other HSA pals want to achieve similar or better results through parallel computing. In most cases, that'll mean using the graphics processor on a chip not only for visuals and gaming, but also for general tasks and apps. This can already be achieved using a programming language called OpenCL, but AMD believes it's too tricky to code and is putting mainstream developers off. Equally, NVIDIA has long had its own language for the same purpose, called CUDA, but it's proprietary. Whatever niche is left in the middle, the HSA Foundation hopes to fill it with an easier and more open standard that is not only cross-OS but also transcends the PC / mobile divide. If it works, it'll give us a noticeable surge in computational power in everyday apps by 2014. If it fails, these new-found friends can go back to the less awkward custom of ignoring each other.

AMD, ARM, Imagination, MediaTek and Texas Instruments Unleash the Next Era of Computing Innovation

–Technology Leaders Establish the HSA Foundation to Create a Unified, Open Industry Standard Architecture for Heterogeneous Processing; Heterogeneous Processors, Which Combine Two or More Different Types of Processors into a Single Chip, Accounted for Nearly Half of All Microprocessor Revenue in 2011 –

BELLEVUE, WASH. – June 12, 2012 – Today at the AMD Fusion Developer Summit (AFDS), global technology leaders came together to announce the formation of the Heterogeneous System Architecture (HSA) Foundation The HSA Foundation is a non-profit consortium established to define and promote an open, standards-based approach to heterogeneous computing that will provide a common hardware specification and broad support ecosystem to make it easier for software developers to deliver innovative applications that can take greater advantage of today's modern processors.

AMD (NYSE: AMD), ARM, Imagination Technologies, MediaTek Inc., and Texas Instruments (TI) (NYSE: TXN) are the initial founding members of the HSA Foundation. The companies will work together to drive a single architecture specification and simplify the programming model to help software developers take greater advantage of the capabilities found in modern central processing units (CPUs) and graphics processing units (GPUs), and unlock the performance and power efficiency of the parallel computing engines found in heterogeneous processors.

By standardizing the heterogeneous programming model, developers can more easily and cost-effectively develop new software tailored to take advantage of the expanding $55.5B heterogeneous (also known as "hybrid") processor market1. The HSA Foundation will help usher in the next era of software innovation, from enabling unprecedented user experiences to improving cloud-based data management, streaming, and security.

"HSA moves the industry beyond the constraints of the legacy system architecture of the past 25-plus years that is now stifling software innovations," said Phil Rogers, HSA Foundation President and AMD Corporate Fellow. "By aiming HSA squarely at the needs of the software developer, we have designed a common hardware platform for high performance, energy efficient solutions. HSA is unlocking a new realm of possibilities across PCs, smartphones, tablets and ultrathin notebooks, as well as the innovative supercomputers and cloud services that define the modern computing experience."

As an independent consortium, the HSA Foundation is open to any and all computing industry professionals with an interest in driving the next era in computing performance and energy efficiency. The HSA Foundation welcomes forward-thinking semiconductor companies, platform and OS vendors, device manufacturers, independent software vendors, academia and open source developers. Members of the HSA Foundation plan to deliver robust development solutions for heterogeneous compute to drive innovative content and applications with developer tools, software developer kits (SDKs), libraries, documentation, training, support and more.

"One year ago, AMD boldly announced a roadmap for making HSA a reality, starting with combining the CPU and GPU as a unified processing engine to create an architecture that would greatly simplify the programming of heterogeneous platforms," said Manju Hegde, corporate vice president of Heterogeneous Applications and Developer Solutions for AMD. "Today, we are continuing our heterogeneous computing leadership and dedication to driving broad industry adoption by making the HSA architecture an open standard."

"We are all demanding more from the technology that connects us to our digital worlds. Graphical interfaces are critical to the user experience but can have a power impact. With open standards, developers can now provide outstanding graphics without compromising power-efficiency," said Jem Davies, ARM Fellow and vice president of Technology, Media Processor Division, ARM. "ARM welcomes the formation of the HSA Foundation and is pleased to be one of the founding members. ARM's extensive experience with heterogeneous systems brings a unique leadership perspective to developing the right compute processor for the right tasks based on the latest ARM technology, such as ARM® Mali™ GPUs and Cortex™ processors."

"Imagination is delighted to be one of the founders of the HSA Foundation. Our long-held view is that heterogeneous processing architectures are fundamental to scalability, flexibility and performance for future SoC (Systems-on-Chip) design," said Tony King-Smith, vice president of Marketing, Imagination Technologies. "We believe that the combination of CPUs with increasingly powerful on-chip GPUs, using industry standard APIs such as OpenCL™, Renderscript Compute, and Direct Compute, is the vital first step along this path. The HSA APIs and tools complement these higher level APIs to help SoC systems engineers create future generation computing platforms. As applications developers embrace the benefits of embracing such architectures, the HSA Foundation will provide a valuable cross-platform, cross-OS means of ensuring maximum heterogeneous application portability and optimization. We look forward to working closely with all of the founders and other members of the HSA Foundation to deliver this key open standard that is set to fuel the future of mass market high performance computing."

"MediaTek is excited about the potential of heterogeneous computing in enabling innovative mobile applications. We believe that an open standard is key to bringing the technology to the mainstream smartphone market, said Chien-Ping Lu, senior director, Corporate Technology Office, MediaTek. "As a chipset and platform supplier with a strong focus on mainstream smartphones, we are excited to join AMD, our IP partners, Imagination, ARM, TI and other industry leaders to promote HSA as the open standard for heterogeneous computing."

"TI's expertise in delivering low-power, high-performance experiences via the smart, multicore architecture of our OMAP™ platform undoubtedly makes our position as a founding member of the HSA Foundation a natural fit," said Matthew Locke, director, Linux Development Center, TI. "We look forward to working with other leaders in the industry to drive adoption of heterogeneous computing as a standard platform across embedded, mobile, personal and cloud computing."

In addition to the founding members, contributor and supporting-level members will assist with research, development, production, manufacture, use, and the sale of HSA and heterogeneous computing software.
