Media Processing: Unseen but Powerful

As I watched yesterday’s SuperBowl, I was painfully aware of each moment of the Patriots’ loss to New York. One thing of which I was blissfully unaware at the time was how much media processing was going on to bring me the crystal clear image on the massive HDTV in front of me. Media processing is what enables on-field action captured by NBC network’s cameras to be then consumed on a high-def television, or ultrabook, or smart phone, or tablet, etc. 

With the surge in connected devices, and in particular connect devices that can view video, the need for media processing is expected to increase dramatically over the coming years.  Not only that, but users are increasingly generating video traffic using handheld devices like smart phones. As the consumption and creation of video ramps up the flow of digital video traffic, the processors performing media processing have expanded from the traditional DSPs to include CPUs, GPUs, SoCs, etc. 

VDC will explore media processing in its upcoming embedded processor market research.  In May 2012, VDC will publish its Track 2, Volume 2: DSPs, GPUs, & Media Processors will take a deep dive into this technology-rich and fast-growing market. We will be reaching out to the leading vendors in each of these markets to learn their perspectives. If you wish to participate in our embedded processor research, please contact me:

GE’s 4th Quarter: The Industrial Crystal Ball for Embedded Hardware in 2012?

General Electric released its 4th Quarter 2011 earnings today. As many know, GE has grown from its humble beginnings in light bulbs to provide a spectrum of products from aircraft engines to financial services. While GE Intelligent Platforms makes embedded hardware, GE as a whole goes far beyond the world of embedded.  As a former GE engineer myself, I have seen firsthand the world-class technology GE brings to market. Since it is a global company with diverse industries, it is typically seen as a bell-weather indicator for the general economy that drives the vertical markets of the embedded industry.

So, what can we glean about the future of the embedded hardware markets from GE’s 4th Quarter Earnings announcement?

First, off, CEO Jeff Immelt mentions “continued volatility for 2012” and restructuring GE’s business in Europe to match market conditions. Obviously, volatility is never a reassuring term. And the situation in Europe appears uncertain. VDC expects that this will mean fewer embedded hardware shipments to Europe, shifting the market share percentages towards the US and Asia-Pacific regions.

Total GE revenues for the quarter were $38 billion - down from many analysts’ expectations, and down 8% from the 4th quarter of 2010. However, this was mostly due to the impact of GE’s sale of its majority stake in NBC Universal. GE is most likely making the right decision to focus on its core competency: industrial products.

But, GE’s global direction aside, what do their division results say for the future? Energy Infrastructure was up 16% Y-o-Y, which is promising. This energy infrastructure would have opportunities for a host of embedded processors, from smart grid applications to wind farms to gas power turbines. For GE, that meant $43.7 billion dollars in revenue. Lots of opportunities going forward assuming this kind of growth continues. Aviation and Healthcare were a more modest 7% growth Y-o-Y, but still over $18 billion in revenue for each segment. Surely there is some embedded hardware associated with that project revenue as well: microcontrollers into engine related equipment; CPUs, GPUs, and more into MRI, CT, X-ray, portable medical equipment, etc. Perhaps most impressive from a revenue growth perspective is Transportation: 45% Y-o-Y.  In 2009 and 2010, this segment posted revenue declines. 

What are the embedded hardware opportunities in transportation?  First, a closer look at what GE defines as Transportation.  This segment includes diesel locomotives, transit propulsion equipment, motorized wheels for off-highway vehicles, and a variety of other motor and system devices.  As the BRIC economies continue to expand, they are no doubt demanding a range of transportation technologies such as the ones GE offers, which all will likely require embedded hardware at some point in their deployment, so the opportunities for embedded hardware here are substantial.

Transportation Embedded Computing: Cruise/Insurance Industry can Learn From Trucking Industry

In the days after the Costa Concordia disaster several things are known.  Approximately 30 people died and the cruise industry (Carnival in particular) and its insurers have experienced huge financial losses. Some say that the ship can be salvaged and back in operation within a year or two but, even so, the losses will be staggering both outright from the lawsuits and loss of cruise business as well as the rescue operations, environmental cleanup, and repair/replacement of the ship. In the aftermath there will be many questions raised about how this could have been prevented and, in my opinion, some of the answers lie within the trucking industry.


As I worked on completing the VDC report on Embedded Integrated Computer Systems (EICS) used throughout the transportation industry I saw several interesting trucking industry applications for these units. The truck application most relevant to the cruise industry takes advantage of there being some type of network connectivity even for mobile units. Embedded computers on the trucks collect, aggregate, and transmit data from sensors located throughout the truck, trailer, and cargo at regular intervals to telematic centers that have specialized embedded computers as well. Among the many things that can be measured and evaluated is driver performance. Are they driving safely? Are they using the most efficient, and safe routes? Are they making any unauthorized detours? Are they being fuel efficient and not placing too much wear and tear on the equipment? Knowing the answers to these questions provides trucking companies with the intelligence needed to make improvements in operational efficiency as well as risk reduction.


As most cruise ships have satellite enabled Wi-Fi services, I believe they could do ship monitoring on a near real-time basis. In fact, it is hard to believe that they don’t already do this or, if they do, the information is not processed into actionable intelligence. One interesting piece of data would be whether Captain Francesco Schettino or other cruise ship captains had taken similar risks/routes before. Cruise ship owners and their insurers should go over data archives to make sure they don’t have pattern of ships taking unnecessary risks. If they don’t have the data, they should install the same infrastructure that many trucking operations already have.

Security concerns represent a market growth opportunity for Embedded Cloud

As I am now working on the latest VDC report on the Embedded Cloud, I have great interest in how suppliers and their customers can take advantage of market opportunities. One obstacle to adoption by many IT and business executives has been security. This concern springs from the idea of sensitive data being transmitted over the cloud. The current VDC report looks at edge node devices that can be used to facilitate connections while, at the same time adding security layers. In my opinion, the weak spots of traditional computer network and file security architectures actually represent a market opportunity because of major differences in structure and security. Yesterday’s MSNBC World News Article highlighted 4 recent mishaps where UK government documents and/or data were lost at least temporarily and in one case actually published.


The lost materials were contained in printouts, laptops, and/or portable media. Even though secure information needs to be readily at hand for those that need it the computers they use to access it are not always in fixed locations with secure networks. It is safe to say that in most cases, even at sea or air, network connections are increasingly available 365days x 24hrs. This is where the embedded cloud architectures can address security issues. With embedded cloud architectures mission critical documents and data do not typically live on portable media. If they do, they are strongly encrypted and the keys are transmitted securely. A user has to present credentials (often biometric) in order to unlock and use/view data/files/documents. A lost laptop or person that becomes un-trusted can be locked out instantly. Biometrics and security questions can eliminate passwords that can be guessed or, possibly written down by the user.


From what I understand, many consumer devices use a similar cloud enabled strategy where purchased materials are stored centrally and secured copies are on the portable device. A loss of the device through theft or malfunction does not mean a loss of the material. Additionally, networked and embedded devices serve as waypoints of access to enterprise networks. Surely these new embedded cloud enabled architectures and devices should draw some interest in the security conscious markets.

Quanta Case versus AMD Underscores Importance of Component/Assembly Testing - Part 2

In the last week’s blog we looked at the semiconductor manufacturing process and the various testing steps that happen as raw silicon is turned into finished devices. In this week's follow up we continue looking at the testing process on the product manufacturing side. Last week we noted that Quanta was manufacturing notebook computers. Because of this, I want to make two observations about the product designs and manufacturing process for notebook computers.

  • Notebook computer suppliers are continually trying to make them as thin and lower cost as possible. This means that Quanta might not have been using sockets and could be mounting the AMD/ATI devices directly on the circuit board. This can be a potential problem in some cases where the device was exposed to humidity before being heated as part of the surface mounted device (SMD) process as it can cause device degradation that leads to future failures.
  • SMD processes increases costs with respect to failures as repairing a SMD CPU or Graphic component on a computer motherboard with hundreds of densely packed conductors is time consuming, difficult, and the scrap rate of the entire unit can be high.
  • As the issue cited in the lawsuit is thermal in nature, it is worth noting that a higher power device such as a CPU or graphics chip often require heat sinks/cooling features to avoid problems. This is another area where manufacturing problems could have been introduced as these devices need to have excellent heat transfer to the cooling feature. Thermal pastes and a process to ensure optimal surface contact between the device and heat sink are needed.

Now, we will look at a few key testing steps on the product manufacturing side.


1.) Incoming Test: This process is considered as being redundant to supplier testing before shipment. Product manufacturers used to commonly test incoming components but, due to cost reduction pressures, that practice is now very uncommon outside the Mil/Aero market. Although it is not likely relevant to the Quanta vs. AMD/ATI case, counterfeiting and other supply chain related cases where lesser specification devices are re-labeled make incoming test more relevant again even in consumer type product manufacture.

2.) Circuit Board/Module Test: The fully assembled circuit board or module is tested before it is embedded in the final product. Thermal transfer issues can be identified by the use of infrared, optical, and or sensors. Repairs are expensive for problems found here but, it is still far less costly than having the product failing downstream.

3.) Highly Accelerated Life Testing (HALT): This is one last type of testing process that might have mitigated AMD and Quanta’s issue at either the packaged device, module/circuit board or completely assembled product stage. The unit being tested is put through extreme levels of hot and cold cycles while also experiencing other stresses such as vibration and g-forces. In this way, a myriad of potential production issues can be detected before the product ends up in customer hands and/or is in a mission critical role that embedded computers are frequently placed in.


In closing, HALT testing is an almost de-facto step in Military products let alone ones that might be launched into space. In Quanta’s case, you would never do this with all of the units but certainly at least a sample of them. If Quanta did not do this, the brand owner should have.  It does seem like a mystery to me about why this case is happening. It should be interesting to find out where the process became broken or which steps were skipped. If something interesting does come to light in the future we will surely revisit this case.

Quanta Case versus AMD Underscores Importance of Component/Assembly Testing - Part 1

This week I read of the lawsuit filed by Quanta Computer Inc. against AMD and its ATI division. The lawsuit alleges that components that they sold Quanta turned out to have heat tolerance related issues that caused the laptops they were used in to fail. It seems a little strange to me that Quanta is the only company with the problem unless they are buying a unique product or batch of products from AMD/ATI. Even so, with a multi-layered testing process the type of problem claimed by Quanta should not happen. The facts of the case will no doubt be revealed if additional claimants come forward and/or the case goes to trial.


Quanta is a Taiwanese contract manufacturer of notebook computers. Since they are a contract manufacturer this means that most of the finished goods they produce are someone else’s brand. They compete on the basis of cost and reliability/quality to get business from the owner of that brand. The damages they are seeking would be from their production losses from needing to repair or scrap finished products and/or subsequent damage to the perception of their own corporate brand.


This case has great relevance to the embedded hardware markets we cover and underscores the importance of a multi-tiered testing process. Therefore, I thought I would share some insights from my 30 year experience in the automatic test industry. I can safely say that despite the perception that testing increases cost, the costs of failure go up significantly at each step of the process between wafer creation and when the finished consumer/industrial product is completed. As one might understand, the absolute worst case is when the manufacturing/design failure occurs in the finished product when it is in the hands of the end customer. How can this be avoided? In this blog, I will look at the manufacturing process for semiconductor devices and, in next week’s follow up, I will look at what happens on the product manufacturing side.


1.) Raw Silicon Wafer: Optical checks are used to look for impurities and surface imperfections before the wafer goes through the extensive chemical/photo process that creates the semiconductor product. This test is very fast and it can save you the cost of chemicals and lost production time.


2.) Wafer Test: The semiconductor devices are still on the round wafer. The wafer is tested by using a probe mechanism that makes temporary contact with all of its contact pads. The tester than makes fairly extensive tests to make sure that the device is worth packaging. Tests can be made at various temperatures as part of this test cycle. In some cases, higher temperatures are used to speed up testing.


3.) Package Device Tests:

  • Quick continuity and resistance tests are made to make sure the wire bonding/connecting process between the individual semiconductor dies and the package were good and that the device does not have any major faults.
  • More detailed tests are then made to ensure the device works perfectly. Several cycles may be involved with the devices being subjected to high or low heat and less than optimal input voltages. The ultimate goal is to subject to the device to similar conditions to what it will see when it is installed in the finished product.

If the device passes through all of these testing steps, it is then further packaged for safe transport and easy assembly into the circuit board by the company like Quanta.In next week's follow up, we will look at what happens on the product manufacturing side.

Is Embedded Hardware Even Safe from Anonymous?

The recent hacking of security firm Stratfor’s website as well as Specialforces.com by hacker group Anonymous has led to questions of how secure large firms are against data theft. One can logically extend the question to the embedded world as well. A prime example in the embedded context is the Stuxnet worm that set back Iran’s nuclear ambitions. As the number of connected devices increases exponentially, the quality of security incorporated into them can only become more paramount. With groups like Anonymous quick to exploit weaknesses, it will likely be a continuous quest to avoid embarrassing security failures at the embedded level.

The needs for this security are evident on many levels. On one hand, as embedded devices are increasingly connected, there are all manners of confidential data that may begin to pass through these embedded systems. For instance, as hospitals begin to incorporate more embedded technology, will patient records become increasingly vulnerable to hacking? Undoubtedly yes. On the other hand, there is the issue of intellectual property in the embedded device itself.  An example is the on-chip memory in a processor which holds valuable code and possibly important data. Both the confidential data packets and the processor IP will require innovative security in the coming years. 

So, what is the embedded industry doing about it? While power, price, and performance have been the classical drivers in the embedded market, there is no doubt that embedded designers are beginning to take security very seriously. The areas of virtualization, encryption, deep packet inspection, etc. are all technical areas that offer potential solutions to security concerns.  As an example, embedded processor supplier Intel’s McAfee division has developed a technology called DeepSAFE, that functions beneath the operating system to protect against stealth rootkits and ATPs.  This kind of technology offers a new level of protection for embedded hardware.  In all likelihood however, as we move into 2012, new technologies will offer new weaknesses for hackers to exploit and for embedded security to defend against such attacks.

5 Keys to Winning and Holding Embedded Computer Share in the Semiconductor Test Market

With respect to Embedded Integrated Computer Systems (EICSs) the semiconductor test market has some unique attributes that may not be immediately obvious or logical to outsiders. The recent VDC report on EICSs used in the industrial automation market estimated 2010 revenues of ~$210 Million for semiconductor processing making it an attractive market to enter. Embedded computing suppliers that thrive here are likely to follow these 5 key rules.


Make it small: Floor space is at a premium in wafer fabrication/semiconductor test facilities. These facilities are often very carefully controlled for dust, static, electrical interference, vibration, temperature, and humidity and therefore represent some of the most expensive square footage in the industrial automation market with respect to operating costs. Computers that can be embedded inside or flexibly mounted to take advantage of available niches in test cells and or test equipment are well received.


Make it Fast: Reducing test times for a given device by even a few milliseconds or having the ability to test many devices in parallel are keys to winning the tester sale. EICSs in addition to deeply embedded Digital Signal Processing (DSP), Field Programmable Gate Arrays (FPGAs) and Application Specific Integrated Circuits (ASICs) are often used in high quantity to achieve this goal. It is important to remember that a semiconductor tester has to be faster than the state of the art devices it is testing. In this blog, I am focusing on EICSs but many of the 5 keys are applicable to deeply embedded computing components as well.


Make it easy/fast to service: Semiconductor testers are extremely expensive with it being quite easy for a well configured unit to cost several million dollars. Even so, the return on investment can be made in only a few weeks to the owner. Therefore, any downtime is very visible and Mean Time to Repair (MTTR) is expected to be in minutes, not hours. Suppliers should design EICSs to have very high reliability but also with easy to access mounts, enclosures, and internal components that allow them to be serviced while wearing a clean room suit and gloves.


Make a flexible configuration: The EICS that is required for a semiconductor tester varies depending on the role it is asked to perform. A production tester needs only a simple Human Machine Interface (HMI) but one that is used for test program development and debugging will need more memory depth and graphics capability to allow the engineer to see and manipulate test patterns as well as analyze the data that is captured while tests are run.


Make it exactly the same – for a long time: A semiconductor test platform will usually be actively sold for at least 5 years but often needs to be supported for at least 10 years and sometimes even longer. Once a tester platform is discontinued a market can develop for the used ones and, in some cases for them can be equal to or even exceeding their original factory price. This can happen when the demand for some legacy semiconductor devices becomes higher than expected. Once a test program has been written and specialized probe cards for wafers and/or interface boards for packaged device handlers have been designed it is extremely expensive process to move them to another tester platform.

Throughout the entire tester platform lifecycle, any changes in embedded computers can require that thousands of hours be spent to re-certify test programs and debug them if problems are seen. Faster computers will often be problematic if, for example, the programmer did not have enough settling time after an instrument was set up before making the measurement.
Changes to an EICS can also lead to increased inventory costs. Because of the MTTR concerns discussed earlier, caches of spare parts are stocked in globally dispersed warehouses and even right at customer sites to allow instant or very quick availability should a failure occur. Changes to an EICS can require multiple sets of slightly different inventory to be stocked.


In summary, a key to winning an embedded hardware product sale to a semiconductor tester company is being active in the design phase and then executing a commitment to provide a stable product through the entire tester product lifecycle. The surprise can be that a newer, faster, or cheaper EICS product will typically not unseat the incumbent unless the original supplier falters in one of the 5 key areas.

An Innovative Application for EICS in Petroleum Product Market Saves Transportation Costs

As part of a VDC project on level sensors I had a very interesting conversation with a UK based distributor of level sensing products. This distributor provides level sensors to oil/kerosene tank manufacturers. During the conversation he mentioning a trend away from from simple sight glass gauges to more expensive electronic level sensing units. Despite the higher price of the new technology it allows several benefits to the end users of petroleum products and the companies that sell and deliver them. By using an Embedded Integrated Computer Systems (EICS) in a telematic/networked monitoring application, a petroleum product delivery company could derive several benefits including lower transportation costs.  Let me provide a little background and explain how this connected process works:


Price Contracts: Small business and residential customers can be severely affected by rising prices. A small disruption like Iran’s activities in the Straits of Hormuz, political unrest in an oil producing country, or changes in weather patterns can cause prices to spike. On the other hand, government intervention, warmer weather and/or lower demand can cause prices to fall. As a result of this uncertainty home, small business, and farm owners will often contract with the local supply/delivery company on a fixed price basis.


Transportation/Delivery: Petroleum products like heating oil usually have to be delivered to these types of customers by truck. Often times these locations are outside urban areas and therefore the heating oil deliveries are more difficult to do efficiently because of distance and customers being less concentrated geographically. The most efficient and cost saving process is to load the truck to the exact level needed to correctly serve all the customers in a selected area and, upon doing so, return to the facility completely empty.


How the Process Works: On the end customer side the electronic level sensor connects to the delivery company’s EICS powered application via a phone or network connection and provides data on the current level of the product in the tank. By doing this the following benefits are seen:

 

  • The delivery company can ensure the customer never runs out even if there is an unexpected surge in usage.
  • The delivery company can efficiently set up truck loads for given sections in its service area.
  • The delivery company can top off tanks when prices are low and let them run lower when prices are high - confident that they will not let customers run out.
  • The customer can get a lower price particularly if they sign the contract.
  • The delivery company can make sure that customers do not break an exclusive contract by taking deliveries from a lower priced competitor. If customers did this, the level sensor would inform the delivery company of an unexpected rise in level in their customer's tank.


And there you have it.  Networked tank level sensors and an EICS controlled application can actually decrease transportation and other costs for petroleum product delivery firms as well as their customers.
