ARM Releases Cortex-A72 for Licensing

On February 3rd, ARM announced a slew of new designs, including the Cortex A72.  Few details were shared with us, but what we learned was that it could potentially redefine power and performance in the ARM ecosystem.  Ryan was invited to London to participate in a deep dive of what ARM has done to improve its position against market behemoth Intel in the very competitive mobile space.  Intel has a leg up on process technology with their 14nm Tri-Gate process, but they are continuing to work hard in making their x86 based processors more power efficient, while still maintaining good performance.  There are certain drawbacks to using an ISA that is focused on high performance computing rather than being designed from scratch to provide good performance with excellent energy efficiency.


ARM has been on a pretty good roll with their Cortex A9, A7, A15, A17, A53, and A57 parts over the past several years.  These designs have been utilized in a multitude of products and scenarios, with configurations that have scaled up to 16 cores.  While each iteration has improved upon the previous, ARM is facing the specter of Intel’s latest generation, highly efficient x86 SOCs based on the 2nd gen 14nm Tri-Gate process.  Several things have fallen into place for ARM to help them stay competitive, but we also cannot ignore the experience and design hours that have led to this product.

(Editor's Note: During my time with ARM last week it became very apparent that it is not standing still, not satisfied with its current status. With competition from Intel, Qualcomm and others ramping up over the next 12 months in both mobile and server markets, ARM will more than ever be depedent on the evolution of core design and GPU design to maintain advantages in performance and efficiency. As Josh will go into more detail here, the Cortex-A72 appears to be an incredibly impressive design and all indications and conversations I have had with others, outside of ARM, believe that it will be an incredibly successful product.)


Cortex A72: Highest Performance ARM Cortex

ARM has been ubiquitous for mobile applications since it first started selling licenses for their products in the 90s.  They were found everywhere it seemed, but most people wouldn’t recognize the name ARM because these chips were fabricated and sold by licensees under their own names.  Guys like Ti, Qualcomm, Apple, DEC and others all licensed and adopted ARM technology in one form or the other.


ARM’s importance grew dramatically with the introduction of increased complexity cellphones and smartphones.  They also gained attention through multimedia devices such as the Microsoft Zune.  What was once a fairly niche company with low performance, low power offerings became the 800 pound gorilla in the mobile market.  Billions of chips are sold yearly based on ARM technology.  To stay in that position ARM has worked aggressively on continually providing excellent power characteristics for their parts, but now they are really focusing on overall performance and capabilities to address, not only the smartphone market, but also the higher performance computing and server spaces that they want a significant presence in.

ARM Releases Top Cortex Design to Partners

ARM has an interesting history of releasing products.  The company was once in the shadowy background of the CPU world, but with the explosion of mobile devices and its relevance in that market, ARM has had to adjust how it approaches the public with their technologies.  For years ARM has announced products and technology, only to see it ship one to two years down the line.  It seems that with the increased competition in the marketplace from Apple, Intel, NVIDIA, and Qualcomm ARM is now pushing to license out its new IP in a way that will enable their partners to achieve a faster time to market.


The big news this time is the introduction of the Cortex A72.  This is a brand new design that will be based on the ARMv8-A instruction set.  This is a 64 bit capable processor that is also backwards compatible with 32 bit applications programmed for ARMv7 based processors.  ARM does not go into great detail about the product other than it is significantly faster than the previous Cortex-A15 and Cortex-A57.

The previous Cortex-A15 processors were announced several years back and made their first introduction in late 2013/early 2014.  These were still 32 bit processors and while they had good performance for the time, they did not stack up well against the latest A8 SOCs from Apple.  The A53 and A57 designs were also announced around two years ago.  These are the first 64 bit designs from ARM and were meant to compete with the latest custom designs from Apple and Qualcomm’s upcoming 64 bit part.  We are only now just seeing these parts make it into production, and even Qualcomm has licensed the A53 and A57 designs to insure a faster time to market for this latest batch of next-generation mobile devices.


We can look back over the past five years and see that ARM is moving forward in announcing their parts and then having their partners ship them within a much shorter timespan than we were used to seeing.  ARM is hoping to accelerate the introduction of its new parts within the next year.

ARM is Serious About Graphics

Ask most computer users from 10 years ago who ARM is, and very few would give the correct answer.  Some well informed people might mention “Intel” and “StrongARM” or “XScale”, but ARM remained a shadowy presence until we saw the rise of the Smartphone.  Since then, ARM has built up their brand, much to the chagrin of companies like Intel and AMD.  Partners such as Samsung, Apple, Qualcomm, MediaTek, Rockchip, and NVIDIA have all worked with ARM to produce chips based on the ARMv7 architecture, with Apple being the first to release the first ARMv8 (64 bit) SOCs.  The multitude of ARM architectures are likely the most shipped chips in the world, going from very basic processors to the very latest Apple A7 SOC.


The ARMv7 and ARMv8 architectures are very power efficient, yet provide enough performance to handle the vast majority of tasks utilized on smartphones and tablets (as well as a handful of laptops).  With the growth of visual computing, ARM also dedicated itself towards designing competent graphics portions of their chips.  The Mali architecture is aimed at being an affordable option for those without access to their own graphics design groups (NVIDIA, Qualcomm), but competitive with others that are willing to license their IP out (Imagination Technologies).

ARM was in fact one of the first to license out the very latest graphics technology to partners in the form of the Mali-T600 series of products.  These modules were among the first to support OpenGL ES 3.0 (compatible with 2.0 and 1.1) and DirectX 11.  The T600 architecture is very comparable to Imagination Technologies’ Series 6 and the Qualcomm Adreno 300 series of products.  Currently NVIDIA does not have a unified mobile architecture in production that supports OpenGL ES 3.0/DX11, but they are adapting the Kepler architecture to mobile and will be licensing it to interested parties.  Qualcomm does not license out Adreno after buying that group from AMD (Adreno is an anagram of Radeon).

AMD and ARM want to bring about an evolution in the server room

DigiTimes spoke with AMD's current server guru about their move from providing only x86/64 based processors in their server chips to the inclusion of ARM cores in the Seattle chip family.  These will be the first processors from AMD using 64-bit Cortex-A57 cores and they hope to sell them to companies who depend on Hadoop or run web hosting services which will benefit from scalability.  As these will be true APUs as well, any application which can be accelerated by a GPU will also greatly benefit from the new design from AMD.  It is AMD's hope that they will be able to offer server customers a choice in the architecture they want to use in their server rooms and able to choose between more than just competing x86/64 chips.


"Commenting on AMD's decision to make ARM-based processors for servers, corporate vice president and general manager of AMD's server business, Suresh Gopalakrishnan, said that as more server applications will show up in the future, different architectures will provide different advantages to clients. Providing solutions based on market demand will be the major business strategy for AMD's server business, Gopalakrishnan noted."

16nm FinFET ARM processors from TSMC soon

Subject: General Tech | April 2, 2013 - 05:57 PM |
Tagged: arm, FinFET, 16nm, TSMC, Cortex-A57

While what DigiTimes is reporting on is only the first tape out, it is still very interesting to see TSMC hitting 16nm process testing and doing it with the 3D transistor technology we have come to know as FinFET.  It was a 64-bit ARM Cortex-A57 chip that was created using this process, unfortunately we did not get much information about what comprised the chip apart from the slide you can see below.


As it can be inferred by the mention that it can run alongside big.LITTLE chips it will not be of the same architecture, nor will it be confined to cellphones.  This does help reinforce TSMC's position in the market for keeping up with the latest fabrication trends and another solid ARM contract will also keep the beancounters occupied.  You can't expect to see these chips immediately but this is a solid step towards an new process being mastered by TSMC.


"The achievement is the first milestone in the collaboration between ARM and TSMC to jointly optimize the 64-bit ARMv8 processor series on TSMC FinFET process technologies, the companies said. The pair has teamed up to produce Cortex-A57 processors and libraries to support early customer implementations on 16nm FinFET for ARM-based SoCs."
