So many cores — what to do with them all?

Multi-core processors are clearly becoming the mainstream for automotive infotainment systems. TI’s OMAP processors and their automotive derivatives use dual A15 cores, Freescale's i.MX 6 boasts up to four A9 cores, and other companies also have multi-core architectures in production or on near-term roadmaps. Quad-core A15 processors are just around the corner. As a percentage of overall die area, the CPU core is relatively small, so SoC producers can lay down multiple cores with little impact on cost. GPUs, on the other hand, represent a large percentage of the die area and, as such, are typically instantiated only once per SoC.

Realistically, infotainment systems should no longer be CPU bound. In fact, when looking at leading-edge SoCs available today, many are asking what to do with all that extra CPU just sitting there, waiting to do something. At first blush, the more obvious areas to merge are infotainment and ADAS, or infotainment and digital instrument clusters. This is, at the highest level, pretty much a no-brainer so long as the safety requirements mandated for clusters and ADAS can be achieved.

Thing is, automotive safety standards like ISO 26262 require system-level certifications. As such, the entire system needs to be certified. Already a daunting task for a standalone ADAS system or digital instrument cluster, the problem can become unmanageable when you include the full infotainment stack.

Think about your car. Your cluster does a handful of operations whereas your infotainment system runs a full navigation system, voice recognition, multimedia, device connectivity, and, in the connected case, cloud services. People don't get frustrated trying to figure out how your cluster works (I hope), and they don't give up trying to figure out how fast the car is moving. The same cannot be said for many infotainment systems shipping today. Ask your mother to pair her cell phone to her car. I dare you! The complexity involved in attempting to certify a system that combines infotainment and cluster functions is orders of magnitude higher than certifying a cluster alone.

All is not lost, however. Virtualization offers an elegant way to isolate multiple systems running on a single multi-core SoC. By using virtualization you could seek certification on the cluster without burdening yourself with the infotainment problem and collapse two formerly discrete systems onto one SoC. You would save money and probably get a promotion to boot. Just one thing: there is still only one GPU on the die and both the infotainment system and the cluster rely heavily on that single GPU.

Enter Red Bend Software, a long-time QNX CAR Platform partner for FOTA. They have taken the challenge of virtualizing the GPU head-on and successfully demonstrated the QNX CAR Platform and a Crank Software-based digital instrument cluster running on dual displays driven by a single OMAP 5 at Telematics Munich. I saw it and was impressed with how snappy performance was on the infotainment side and how smooth the needles were (60+ fps) on the cluster.


Using virtualization to drive dual displays from a single TI OMAP 5 processor.

According to Red Bend, they have designed a GPU-sharing architecture that enables multiple guest operating systems to access hardware accelerators, including the GPU, providing isolation between the operating systems while having a minimal impact on overall performance (which probably isn't a huge deal considering how many CPU cores are going to be shipping on a single SoC in the near term). It sounds impressive, but seeing is believing.

Red Bend will next show this demo in the TI Suite at CES (N115 in the North Hall). If system consolidation is something that keeps you up at night, you should really stop by to see what they have done.

C3 recap: The future of the connected car

UPDATE: CE Week has uploaded audio and video of the C3 panels that Derek covers in this post. To hear what experts from companies like AT&T, BMW, Delphi, GM, and QNX see on the horizon for the connected car, visit the Connected Car Conference website — Ed.

Derek Kuhn

“Automotive has always been a wellspring of technology and innovation.” Those ten words, spoken by Doug Newcomb, car technology consultant and conference chair — and occasional QNX blog contributor — brought the Connected Car Conference (C3) to a successful close. The conference, co-located with CEA’s CE Week in New York City, featured panels on issues and trends for the connected car: big data, the future of radio, driver distraction, and more.

I was honored to sit on a panel that included executives from General Motors, AT&T Emerging Devices, and Audiovox, and that tackled the question on the minds of everyone in the industry: how can cars keep pace with consumer electronics? Traditionally, the speed of car development has trailed consumer devices, but with consumers looking at their cars as another connected gadget, the industry is working to bring technology into the car faster, while still providing a safe, reliable experience. As GM’s Tim Nixon put it, “we want to make the car better from the day you drive it off the lot.”

Striking a balance
Tim’s comment touches on something we frequently discuss — the significance of over-the-air (OTA) updates in ensuring that a car always has the latest technology. In fact, my colleague, Tina Jeffrey, just wrote a blog post on the topic; it's worth a read. Another point that came up is the need to balance security with consumers’ desire for cutting-edge technology. As I pointed out, not all infotainment systems are created equal — security shouldn’t be an afterthought in the pursuit of the latest and greatest tech. Rather, it should be deeply engrained in each step of the software development process. At the same time, consumer choice also has to be balanced with what OEMs are comfortable with.

Driving big data

John Quain of the New York Times hosted a panel on big data, which was full of insights on how data is being used to connect drivers and their cars. In response to the question, “how can big data in automotive save lives?” Delphi’s Doug Welk commented that, while data on crashes was abundant and readily available, data on near misses — which is even more important to understanding how to prevent accidents — is scant. Telenav’s Niall Berkey pointed out something that my colleague Andrew Poliak often discusses: the importance of the car as a sensor. For instance, by using information on how a driver is behaving, a car could activate assisted-driving technologies to reduce the likelihood of an accident.

Dealing with distraction
During the “Dealing with Driver Distraction” panel, representatives from the Auto Alliance of Automobile Manufacturers, Nuance, NVIDIA, and Pioneer spoke on how the industry is working to curb distraction. Gloria Bergquist of the Auto Alliance stated that the concern is nothing new; when car radios were first introduced in the middle of the last century, industry watchers claimed that drivers’ attention would be diverted by the novelty.

Gloria also drew from her organization’s recent report, which showed that most drivers overestimate how well they can handle distractions and think that it’s other drivers who can’t cope. Erik Clauson of Nuance discussed how voice recognition technologies — like the QNX intent framework — can play a large role in decreasing the cognitive load of drivers. Dave Anderson of NVIDIA defended skeumorphism — a design aesthetic that has received much criticism as of late — as a way to increase the intuitiveness of user interfaces and therefore decrease distraction. For example, digital instrument clusters that look like conventional (and familiar) analog instruments can enhance the driving experience.

Continuing the conversation
The day ended with a networking reception — a unique opportunity to pick the brains of the some of the industry’s thought leaders and observers. While I got to spend only a short time in New York for the event, I am look forward to next year when we can continue this conversation on the industry’s challenges and innovations.

OTA software: not just building castles in the air

Tina Jeffrey

After attending Telematics Detroit earlier this month, I realized more than ever that M2M will become the key competitive differentiator for automakers. With M2M, automakers can stay connected with their vehicles and perhaps more importantly, vehicle owners, long after the cars have been driven off dealer lots. Over-the-air (OTA) technology provides true connectivity between automakers and their vehicles, making it possible to upgrade multiple systems, including electronic control unit (ECU) software, infotainment systems that provide navigation and smartphone connectivity, and an ever-increasing number of apps and services.

Taken together, the various systems in a vehicle contain up to 100 million lines of code — which makes the 6.5 million lines of code in the Boeing 787 Dreamliner seem like a drop in the proverbial bucket. Software in cars will only continue to grow in both amount and complexity, and the model automakers currently use to maintain and upgrade vehicle software isn’t scalable.

Vehicle owners want to keep current with apps, services, and vehicle system upgrades, without always having to visit the dealer. Already, vehicle owners update many infotainment applications by accepting software pushed over the air, just like they update applications on their smartphones. But this isn’t currently the case for ECUs, which require either a complete module replacement or module re-flashing at a dealership.

Pushing for updates
Automakers know that updates must be delivered to vehicle owners in a secure, seamless, and transparent fashion, similar to how OTA updates are delivered to mobile phones. Vehicle software updates must be even more reliable given they are much more critical.


BlackBerry’s OTA solution: Software Update Management for Automotive service

With OTA technology, automakers will use wireless networks to push software updates to vehicles automatically. The OTA service will need to notify end-users of updates as they become available and allow the users to schedule the upgrade process at a convenient time. Large software updates that may take a while to download and install could be scheduled to run overnight while the car is parked in the garage, making use of the home Wi-Fi connection. Smaller size updates could be delivered over a cellular connection through a tethered smartphone, while on a road trip. In this latter scenario, an update could be interrupted, for instance, if the car travels into a tunnel or beyond the network area.

A win-win-win
Deployment of OTA software updates is a winning proposition for automakers, dealers, and vehicle owners. Automakers could manage the OTA software updates themselves, or extend the capability to their dealer networks. Either way, drivers will benefit from the convenience of up-to-date software loads, content, and apps with less frequent trips to the dealer. Dealership appointments would be limited to mechanical work, and could be scheduled automatically according to the vehicle’s diagnostic state, which could be transmitted over the air, routinely, to the dealer. With this sharing of diagnostic data, vehicle owners would better know how much they need to shell out for repairs in advance of the appointment, with less chance of a shocking repair-cost phone call.

OTA technology also provides vehicle owners and automakers with the ability to personalize the vehicle. Automaker-pushed content can be carefully controlled to target the driver’s needs, reflect the automaker's brand, and avoid distraction — rather than the unrestricted open content found on the internet, which could be unsafe for consumption while driving. Overall, OTA software updates will help automakers maintain the customers they care about, engender brand loyalty, and provide the best possible customer experience.

Poised to lead
Thinking back to Telematics Detroit, if the number of demos my BlackBerry colleagues gave of their Software Update Management for Automotive service is any indication, OTA will transform the auto industry. According to a study from Gartner ( “U.S. Consumer Vehicle ICT Study: Web-Based Features Continue to Rise” by Thilo Koslowski), 40 percent of all U.S. vehicle owners either “definitely want to get” or at least are “likely to get” the ability for wireless software updates in their next new vehicle — making it the third most demanded automotive-centric Web application and function.

BlackBerry is poised to lead in this space, given their expertise in infrastructure, security, software management, and close ties to automotive. They were leaders in building an OTA solution for the smartphone market, and now again are among the first entrants in enabling a solution that is network, hardware, firmware, OS, software, and application agnostic.

Making the growing number of connected cars continuously better

Guest post by Yoram Berholtz, Director of Market Adoption, Red Bend Software

More and more car manufacturers are implementing over-the-air software updates as a way to improve functionality, fix software defects, and guarantee a user experience that is continuously better. Car manufacturers GM (OnStar) and Daimler (MBRACE 2) have been leaders in recognizing the value of over-the-air updates for improving their infotainment systems. For example, GM recently updated the Bluetooth technology in OnStar to support late model smartphones.

The ability to update the infotainment system even manually is an improvement over requiring car owners to visit the dealership every time a new software update is available. As an example, Ford recently launched a program for consumers to update their own MyFord Touch system by mailing Ford owners a USB drive loaded with the appropriate software updates. However, many consumers view manual updates as bothersome and complicated, which means some systems simply don’t get updated. Today’s car owners expect their infotainment systems to have the same user experience as their mobile devices, and that means performing software updates over-the-air.

Scope and scale
According to ABI Research, there will be 210 million connected cars by 2016, and together with the ability to tether the smartphone to the infotainment system, the main enabler for doing over-the-air update is there: connectivity.

The updating solution must have scope and scale. Scope is the ability and the flexibility to update all of the memory including the user and system space with full or discrete components. As well, the solution must scale to manage millions of updates without failure and with the highest security possible. This, for example, would enable users of the QNX CAR application platform to update not only the QNX CAR software but also individual applications such as Pandora or the Weather channel.

In the mobile industry, where over-the-air software updating is a well-established practice, manufacturers and service providers realize many benefits:
 

• Cost reduction — Over-the-air software updates have reduced warranty costs
   
• Update success rate — Over-the-air software updates deliver the highest success rate
   
• Faster updates — Sending only the code that is different between the original software and the update (often called the delta) is faster and uses less bandwidth
   
• Customer satisfaction — A fast and automatic over-the-air process eliminates the need for the consumer to go to the dealer

A holistic solution
The mobile industry has enjoyed these benefits for some time. The automotive industry needs over-the-air updating even more so because the infotainment system includes millions of lines of code and updating this software requires a holistic solution that can manage the whole software life-cycle.

Red Bend Software has integrated its vRapid Mobile® update technology, which exists in more than 1.6 billion devices, into the QNX CAR platform. This enables car manufacturers and Tier 1 providers the flexibility to create an over-the-air update strategy that is optimized for infotainment systems and also for other embedded systems in the car. Today, infotainment systems are central in the car cockpit experience. These systems contain not only the QNX CAR 2 platform but also a variety of applications. Applications for the auto industry are not like applications for mobile devices. Applications for the auto industry have been modified in order to meet the car environment and have more voice activation and larger buttons so the driver isn’t distracted.

Car manufacturers are looking at their infotainment systems as product differentiators and as a valuable asset to generate revenues after the sale. The automobile industry doesn’t want Over-the-Top companies controlling the delivery channel to the infotainment system and weakening automotive brands. With a holistic Firmware Over-the-Air (FOTA) solution, car manufacturers can guarantee ownership of the infotainment firmware and applications, increasing the consumers’ perceived value through a much stronger brand.

Not if, but when
No longer is the auto industry asking whether or not to perform over-the-air updates. Now car manufacturers and tier one suppliers are asking how often and when should updates be provided during the life-cycle of the infotainment system.

Recall? What recall?

Red Bend demonstrates firmware-over-the-air (FOTA) updates of QNX CAR 2 application platform at Telematics Munich

I think anyone with a passing knowledge of software development in automotive would agree that the infotainment systems currently under development are light years ahead of the systems that shipped only 5 years ago. The blurring of the automotive and the consumer experience is accelerating at an amazing pace. And the processing power being specified for next-gen infotainment aligns with what is expected in advanced smart phones.

It's no surprise, then, that the size of the code base and the complexity of the underlying software is growing at a similar pace. This complexity creates a maintenance challenge. On your phone, upgrades are pushed out regularly in a way that you barely notice: you get a notification of an update, push a couple buttons, and presto, you are up to date. In automotive, if we stick to the traditional methodology, this same type of upgrade would require a recall. You'd have to take your car to the dealership and they would reflash whatever needs to be updated. Expensive for the auto manufacturer and a big pain for the consumer.

Thankfully, people are thinking about this. Companies like Red Bend Software have cut their teeth in the mobile space, specializing in firmware-over-the-air updates, or FOTA for short. They can generate something called a delta file, which effectively encapsulates the difference (or delta) between what is currently on the end device and the new software build. In some cases, the file can be up to 50 times smaller than the new build. They also have the ability to track current load status of all the devices deployed.

So what does that get you? Using FOTA, OEMs will be able to minimize the network bandwidth required for upgrades and to manage the update process remotely, moving us all towards that Zen state of automagic. I don't know about you, but anything that saves me a trip to the dealer is a good thing.

Red Bend will demonstrate this capability by updating versions of the QNX CAR 2 application platform this week at Telematics Munich. So if you happen to be there, do stop to check it out.
