The future of ARM in the eyes of Nvidia

Project Denver” Processor to Usher in New Era of Computing

As you may have seen, NVIDIA has already announced that it is developing high-performance ARM-based CPUs designed to power future products ranging from personal computers to servers and supercomputers.

Known under the internal codename “Project Denver,” this initiative features an NVIDIA CPU running the ARM instruction set, which will be fully integrated on the same chip as the NVIDIA GPU. This initiative is extremely important for NVIDIA and the computing industry for several reasons.

NVIDIA’s project Denver will usher in a new era for computing by extending the performance range of the ARM instruction-set architecture, enabling the ARM architecture to cover a larger portion of the computing space. Coupled with an NVIDIA GPU, it will provide the heterogeneous computing platform of the future by combining a standard architecture with awesome performance and energy efficiency.

This new processor stems from a strategic partnership, also announced today, in which NVIDIA has obtained rights to develop its own high performance CPU cores based on ARM’s future processor architecture. In addition, NVIDIA licensed ARM’s current Cortex™-A15 processor for its future-generation Tegra® mobile processors.

ARM is already the standard architecture for mobile devices. Project Denver extends the range of ARM systems upward to PCs, data center servers, and supercomputers. ARM’s modern architecture, open business model, and vibrant eco-system have led to its pervasiveness in cell phones, tablets, and other embedded devices. Denver is the catalyst that will enable these same factors to propel ARM to become pervasive in higher-end systems.

As Jen-Hsun Huang, president and chief executive officer of NVIDIA, said

ARM is the fastest-growing CPU architecture in history. This marks the beginning of the Internet Everywhere era, where every device provides instant access to the Internet, using advanced CPU cores and rich operating systems.

ARM’s pervasiveness and open business model make it the perfect architecture for this new era. With Project Denver, we are designing a high-performing ARM CPU core in combination with our massively parallel GPU cores to create a new class of processor.

Denver frees PCs, workstations and servers from the hegemony and inefficiency of the x86 architecture. For several years, makers of high-end computing platforms have had no choice about instruction-set architecture. The only option was the x86 instruction set with variable-length instructions, a small register set, and other features that interfered with modern compiler optimizations, required a larger area for instruction decoding, and substantially reduced energy efficiency.

Denver provides a choice. System builders can now choose a high-performance processor based on a RISC instruction set with modern features such as fixed-width instructions, predication, and a large general register file. These features enable advanced compiler techniques and simplify implementation, ultimately leading to higher performance and a more energy-efficient processor.

Microsoft’s announcement that it is bringing Windows to ultra-low power processors like ARM-based CPUs provides the final ingredient needed to enable ARM-based PCs based on Denver. Along with software stacks based on Android, Symbian, and iOS, Windows for ultra-low power processors demonstrates the huge momentum behind low-power solutions that will ultimately propel the ARM architecture to dominance.

An ARM processor coupled with an NVIDIA GPU represents the computing platform of the future. A high-performance CPU with a standard instruction set will run the serial parts of applications and provide compatibility while a highly-parallel, highly-efficient GPU will run the parallel portions of programs.

The result is that future systems – from the thinnest laptops to the biggest data centers, and everything in between — will deliver an outstanding combination of performance and power efficiency. Their processors will provide the best of both worlds, while enabling increased battery life for mobile solutions. We’re really excited to help engineer smarter brains for the next major era in computing.
