A pair of engineers in Singapore, Andrew "Bunny" Huang and Sean Cross, have developed a working laptop which was designed to be completely open sourced, with no proprietary drivers or software of any kind. The Novena laptop is powered by a Cortex A9 and an FPGA and runs Debian, even communications are handled by a software-defined radio board. This is more of a proof of concept than a marketable machine but the links at The Register will take you to the details on how you could build one yourself. Even the bezel is open source and modifiable, it is a laptop with an upgradable screen!
"This week, the pair developing the Novena open laptop have provided an update on their work. The idea is to develop a usable system that is completely open to customization and scrutiny – from the electronics to the firmware to the operating system to the applications."

A 24-core design based on 64-bit ARM architecture has reached the prototype phase, in a large LGA package resembling an Intel Xeon CPU.
From the report published by PC World:
"Qualcomm demonstrated a pre-production chip in San Francisco on Thursday. It's a purpose-built system-on-chip, different from its Snapdragon processor, that integrates PCIe, storage and other features. The initial version has 24 cores, though the final part will have more, said Anand Chandrasekher, Qualcomm senior vice president."

Qualcomm built servers as proof-of-concept with this new processor, "running a version of Linux, with the KVM hypervisor, streaming HD video to a PC. The chip was running the LAMP stack - Linux, the Apache Web server, MySQL, and PHP - and OpenStack cloud software," according to PC World. The functionality of this design demonstrate the chip's potential to power highly energy-efficient servers, making an obvious statement about the potential cost savings for large data companies such as Google and Facebook.
Business Model Based on Partnerships
|Alexandru Voica works for Imagination Technologies. His background includes research in computer graphics at the School of Advanced Studies Sant'Anna in Pisa and a brief stint as a CPU engineer, working on several high-profile 32-bit processors used in many mobile and embedded devices today. You can follow Alex on Twitter @alexvoica.|
Some months ago my colleague Rys Sommefeldt wrote an article offering his (deeply) technical perspective on how a chip gets made, from R&D to manufacturing. While his bildungsroman production covers a lot of the engineering details behind silicon production, it is light on the business side of things; and that is a good thing because it gives me opportunity to steal some of his spotlight!
This article will give you a breakdown of the IP licensing model, describing the major players and the relationships between them. It is not designed to be a complete guide by any means and some parts might already sound familiar, but I hope it is a comprehensive overview that can be used by anyone who is new to product manufacturing in general.
The diagram below offers an analysis of the main categories of companies involved in the semiconductor food chain. Although I’m going to attempt to paint a broad picture, I will mainly offer examples based on the ecosystem formed around Imagination (since that is what I know best).
A simplified view of the manufacturing chain
Let’s work our way from left to right.
Traditionally, these are the companies that design and sell silicon IP. ARM and Imagination Technologies are perhaps the most renowned for their sub-brands: Cortex CPU + Mali GPU and MIPS CPU + PowerVR GPU, respectively.
Given the rapid evolution of the semiconductor market, such companies continue to evolve their business models beyond point solutions to become one-stop shops that offer more than for a wide variety of IP cores and platforms, comprising CPUs, graphics, video, connectivity, cloud software and more.

Have you ever wondered how a mobile GPU is born? Or how the architecture of a mobile GPU like ARM Mali differs from the technology in your discrete PC graphics card? Perhaps you just want to know if ideas like HBM (high bandwidth memory) are going to find their way into the mobile ecosystem any time soon?
Josh and I sat down (virtually) with ARM's VP of Technology and Fellow, Jem Davies, to answer these questions and quite a bit more. The resulting interview will shed light on the design process of a mobile GPU, how you get the most out of an SoC that measures power by the milliwatt, what the world of mobile benchmarking needs to do to clean up its act and quite a bit more.
You'd be hard pressed to find a better way to spend the next hour of your day as you will without a doubt walk away more informed about the world of smartphones, tablets and GPUs.
Some Fresh Hope for 2016
EDIT 2015-05-07: A day after the AMD analyst meeting we now know that the roadmaps delivered here are not legitimate. While some of the information is likely correct on the roadmaps, they were not leaked by AMD. There is no FM3 socket, rather AMD is going with AM4. AMD will be providing more information throughout this quarter about their roadmaps, but for now take all of this information as "not legit".
SH SOTN has some eagle eyes and spotted the latest leaked roadmap for AMD. These roadmaps cover both mobile and desktop, from 2015 through 2016. There are obviously quite a few interesting tidbits of information here.
On the mobility roadmap we see the upcoming release of Carrizo, which we have been talking about since before CES. This will be the very first HSA 1.0 compliant part to hit the market, and AMD has done some really interesting things with the design in terms of performance, power efficiency, and die size optimizations. Carrizo will span the market from 15 watts to 35 watts TDP. This is a mobile only part, but indications point to it being pretty competent overall. This is a true SOC that will support all traditional I/O functions of older standalone southbridges. Most believe that this part will be manufactured by GLOBALFOUNDIRES on their 28 nm HKMG process that is more tuned to AMD's APU needs.
Carrizo-L will be based on the Puma+ architecture and will go from 10 watts to 15 watts TDP. This will use the same FP4 BGA connection as the big Carrizo APU. This should make these parts more palatable for OEMs as they do not have to differentiate the motherboard infrastructure. Making things easier for OEMs will give more reasons for these folks to offer products based on Carrizo and Carrizo-L APUs. The other big reason will be the GCN graphics compute units. Puma+ is a very solid processor architecture for low power products, but these parts are still limited to the older 28 nm HKMG process from TSMC.
One interesting addition here is that AMD will be introducing their "Amur" APU for the low power and ultra-low power markets. These will be comprised of four Cortex-A57 CPUs combined with AMD's GCN graphics units. This will be the first time we see this combination, and the first time AMD has integrated with ARM since ATI spun off their mobile graphics to Qualcomm under the "Adreno" branding (anagram for "Radeon"). What is most interesting here is that this APU will be a 20 nm part most likely fabricated by TSMC. This is not to say that Samsung or GLOBALFOUNDRIES might be producing it, but those companies are expending their energy on the 14 nm FinFET process that will be their bread and butter for years to come. This will be a welcome addition to the mobile market (tablets and handhelds) and could be a nice profit center for AMD if they are able to release this in a timely manner.
2016 is when things get very interesting. The Zen x86 design will dominate the upper 2/3 of the roadmap. I had talked about Zen when we had some new diagram leaks yesterday, but now we get to see the first potential products based off of this architecture. In mobile it will span from 5 watts to 35 watts TDP. The performance and mainstream offerings will be the "Bristol Ridge" APU which will feature 4 Zen cores (or one Zen module) combined with the next gen GCN architecture. This will be a 14nm part, and the assumption is that it will be GLOBALFOUNDRIES using 14nm FinFET LPP (Low Power Plus) that will be more tuned for larger APUs. This will also be a full SOC.
The next APU will be codenamed "Basilisk" that will span the 5 watt to 15 watt range. It will be comprised of 2 Zen cores (1/2 of a Zen module) and likely feature 2 to 4 MB of L3 cache, depending on power requirements. This looks to be the first Skybridge set of APUs that will share the same infrastructure as the ARM based Amur SOC. FT4 BGA is the basis for both the 2015 Amur and 2016 Basilisk SOCs.
Finally we have the first iteration of AMD's first ground up implementation of ARM's ARMv8-A ISA. The "Styx" APU features the new K12 CPU cores that AMD has designed from scratch. It too will feature the next generation GCN units as well as share the same FT4 BGA connection. Many are anxiously watching this space to see if AMD can build a better mousetrap when it comes to licensing the ARM ISA (as have Qualcomm, NVIDIA, and others).
2015 shows no difference in the performance desktop space, as it is still serviced by the now venerable Piledriver based FX parts on AM3+. The only change we expect to see here is that there will be a handful of new motherboard offerings from the usual suspects that will include the new USB 3.1 functionality derived from a 3rd party controller.
Mainstream and Performance will utilize the upcoming Godavari APUs. These are power and speed optimized APUs that are still based on the current Kaveri design. These look to be a simple refresh/rebadge with a slight performance tweak. Not exciting, but needs to happen for OEMs.
Low power will continue to be addressed by Beema based APUs. These are regular Puma based cores (not Puma+). AMD likely does not have the numbers to justify a new product in this rather small market.
2016 is when things get interesting again. We see the release of the FM3 socket (final proof that AM3+ is dead) that will house the latest Zen based APUs. At the top end we see "Summit Ridge" which will be composed of 8 Zen cores (or 2 Zen modules). This will have 4 MB of L2 cache and 16 MB of L3 cache if our other leaks are correct. These will be manufactured on 14nm FinFET LPE (the more appropriate process product for larger, more performance oriented parts). These will not be SOCs. We can expect these to be the basis of new Opterons as well, but there is obviously no confirmation of that on these particular slides. This will be the first new product in some years from AMD that has the chance to compete with higher end desktop SKUs from Intel.
From there we have the lower power Bristol Ridge and Basilisk APUs that we already covered in the mobile discussion. These look to be significant upgrades from the current Kaveri (and upcoming Godavari) APUs. New graphics cores, new CPU cores, and new SOC implementations where necessary.
AMD will really be shaking up the game in 2016. At the very least they will have proven that they can still change up their game and release higher end (and hopefully competitive) products. AMD has enough revenue and cash on hand to survive through 2016 and 2017 at the rate they are going now. We can only hope that this widescale change will allow AMD to make some significant inroads with OEMs on all levels. Otherwise Intel is free to do what they want and what price they want across multiple markets.
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.

Tagged: arm, Q1 2015
ARM seems to be completely ignoring the sales downturn that almost every single component manufacturer has seen in this quarter, as well as previous ones, turning in on increase of 14% on revenue and 24% on profit in Q1 of 2015. As The Register points out that equates to 450 chips selling every second, something even automated stock trading algorithms have to be impressed by. Royalty revenue increased by 31% thanks to Mali, regardless of Apple's decision not to use that chip in their iPhone 6. You can expect to see more news on ARM from us in the near future and you can expect the news to be good for their investors and users.
"The first three months of 2015 have been good to ARM, which saw revenues of $348.2m and pre-tax profits of $120.5m in the first quarter, with 3.8 billion ARM-based chips shipped - or more than 450 chips per second."

Not only has the NVIDIA sueball pitch been judged to be in play and will continue to run but now according to news The Register has heard Samsung may be using their own in-house ARM processors for their next products. The rumour is that they have spend four years developing an ARM processor from the ground up which will make it much less likely that Qualcomm will be able to sell their next generation 64 bit Snapdragon Kyro processor to Samsung, which is after all a modified ARM v8-a chip as opposed to a custom built processor. Qualcomm does have other customers than Samsung, including HTC, Amazon and LG who might be interested in the new Snapdragon 820 but it does look bleak for their next generation processor. The only leverage Qualcomm has now is that Samsung will likely be the ones fabbing many of the new Snapdragon 820's, perhaps they can strike a deal for some lower cost mobile devices once Kyro matures.
"Samsung will join Apple and other mobile semiconductor rivals in producing chips powered by homegrown, proprietary application cores in 2016, according to a new report."

Tagged: skybridge, HPC, arm, amd
The details are a little sparse but we now have hints of what AMD's plans are for next year and 2017. In 2016 we should see AMD chips with ARM cores, the Skybridge architecture which Josh described almost a year ago, which will be pin compatible allowing the same motherboard to run with either an ARM processor or an AMD64 depending on your requirements. The GPU portion of their APUs will move forward on a two year cycle so we should not expect any big jumps in the next year but they are talking about an HPC capable part by 2017. The final point that The Register translated covers that HPC part which is supposed to utilize a new memory architecture which will be nine times faster than existing GDDR5.
"Consumer and commercial business lead Junji Hayashi told the PC Cluster Consortium workshop in Osaka that the 2016 release CPU cores (an ARMv8 and an AMD64) will get simultaneous multithreading support, to sit alongside the clustered multithreading of the company's Bulldozer processor families."
