TrendMicro discovered vulnerabilities in the Qualcomm Snapdragon 800 series, including the 800, 805 and 810 on devices running a 3.10-version kernel. They have privately discussed the issue with Google who have since pushed out updates to resolve these issues on their phones, preventing attackers from gaining root access with a specially crafted app. Unfortunately that is the tip of the iceberg as according to Qualcomm more than a billion devices use Snapdragon processors or modems, many of them IoT devices which have not had this update. With the already fragmented market getting worse as everyone and their dog are now creating IoT devices the chances are very good that your toaster, fridge and other random internet connected devices are vulnerable and will remain so.
You should think twice when considering the balance of convenience and security when you are purchasing internet connected household appliances and other IoT devices. You can see what Slashdot readers think about this here if you so desire.
"Security experts at Trend Micro have discovered a vulnerability in Qualcomm Snapdragon-produced SoC devices. In fact, it is the same vulnerability that cropped up earlier in the month, affecting Nexus 5, Nexus 6, Nexus 6P and Samsung Galaxy Edge Android handsets. This in itself is concerning as these are devices that are no longer in line for security updates, but more concerning is the fact that the same chips are used in IoT devices."

The new LG G5 flagship smartphone offers a unique combination of form factor, performance and modularity that no previous smartphone design has had. But will you want to buy in?
I had a feeling that the Snapdragon 820 SoC from Qualcomm would make an impression at Mobile World Congress this year and it appears the company has improved on the previous flagship processor quite a bit. Both Samsung and LG have implemented it into the 2016 models, including the new G5, offering up a combination of performance and power efficiency that is dramatically better than the 810 that was hindered by heat and process technology concerns.
Along with the new processor, the G5 includes 4GB of RAM, 32GB of on-board storage with micro SD expansion, a 2,800 mAh battery and Android 6.0 out of the box. The display is 5.3-in and uses LG IPS technology with a 2560x1440 resolution, resulting in an impressive 554 PPI. LG has updated the USB connection to Type-C, a move that Samsung brushed off as unnecessary at this time.
The phones design is pretty standard and will look very familiar to anyone that has handled a G4 or similar flagship smartphone in recent months. It was bigger in the hand than the iPhone 6s but considering the panel size differences, it was more compact than expected.
Modularity is the truly unique addition to the G5 though. The battery is replaceable by sliding out a bottom portion of the phone, released with a tab on the left side. This allows LG to maintain the metal body construction but still offer flexibility for power users that are used to having extra batteries in their bag. This mechanism also means LG can offer add-on modules for the phone.
The first two available will be the LG Cam Plus and the LG Hi-Fi Plus. The Cam Plus gives the phone a camera grip as well as dedicated buttons for the shutter, video recording and zoom. Including an extra 1,200 mAh of battery is a nice touch too. The Hi-Fi Plus module has a DAC and headphone amplifier enbeded in it and can also be used connected to a PC through the USB Type-C connection; a nice touch.
I was overall pretty impressed with what LG had to offer with the G5. Whether or not the modular design gains any traction will have to be seen; I have concerns over the public's desire to carry around modules or affect the form factor of their phones so dramatically.

Earlier this month, Qualcomm announced the creation of the Snapdragon Wear platform and the Snapdragon Wear 2100 SoC, the very first in a new family of products built to address consumer wearables market. Even though the Snapdragon 400 series of processors had already found its way into a large majority (65% according to Qualcomm) of all of the currently shipping Android Wear watches, Qualcomm hopes that the improvements in the Snapdragon Wear 2100 will further the company's market share and improve on the experiences that users have with wearable products.
Snapdragon Wear 2100 offers several advantages over the Snapdragon 400 series of SoCs:
Utilizing Qualcomm Technologies’ expertise in connectivity and compute, the Snapdragon Wear platform consists of a full suite of silicon, software, support tools, and reference designs to allow mobile, fashion, and sports customers to bring a diverse range of full-featured wearables to customers quickly. Available in both tethered (Bluetooth® and Wi-Fi®) and connected (4G/LTE and 3G) versions, Snapdragon Wear 2100 innovates along four wearables core vectors:
- Smaller Size – 30 percent smaller than the popular Snapdragon 400, Snapdragon Wear 2100 can help enable new, thinner, sleeker designs
- Lower Power – 25 percent lower power than the Snapdragon 400 across both tethered and connected use cases, allowing for longer day of use battery life
- Smarter Sensors – With an integrated, ultra-low power sensor hub, Snapdragon Wear 2100 enables richer algorithms with greater accuracy than the Snapdragon 400
- Always Connected – Next-generation LTE modem with integrated GNSS, along with low power Wi-Fi and Bluetooth delivers an always connected experience
There is no direct mention of comparative performance though, something I am looking to get answered this week.
This week's announcement from Qualcomm is the addition of three new partners for the Snapdragon Wear platform, on top of the launch partner LG. The new names might not be household brands but they will offer a strong growth segment for Qualcomm as more vendors enter the wearables markets through ODMs.
- Borqs – A global leader in software and products for IoT providing customizable, differentiated and scalable Android-based smart connected devices and cloud service solutions, Borqs is offering connected (3G/4G) and tethered (Wi-Fi®/Bluetooth®) smartwatch and kid watch reference designs based on Snapdragon Wear 2100.
- Compal – A global manufacturer of notebook PCs, smartphone, tablet and display products and smart wearable devices, Compal is delivering reference designs and device production based on Snapdragon Wear 2100 supporting both Android Wear and Android operating systems and targeting connected (3G/4G) and tethered (Wi-Fi/Bluetooth) use cases.
- Infomark – An early innovator in the emerging kid watch segment, where the company has previously launched two generations of products (JooN1, JooN2) based on Qualcomm Technologies, Infomark is offering a reference design based on Snapdragon Wear 2100 targeting kid and elderly watch segments.
I should be getting hands-on with hardware built on the Snapdragon Wear 2100 SoC from LG and these three new partners this week while at Mobile World Congress 2016, so stayed tuned for more coverage!

As we prepare for the onslaught of new mobile devices and technologies being announced at Mobile World Congress in Barcelona, the low-level Vulkan API begins its campaign to take hold in the PC and mobile spaces, superceding the OpenGL standard that exists today in hopes of providing a more efficient use of compute resources across the industry.
Qualcomm announced official support for the Vulkan API on its Adreno 530 GPU and the Snapdragon 820 processor. Vulkan API support will be coming for upcoming other unannounced Adreno 5xx series GPUs and currently shipping Adreno 4xx GPUs, allowing us to wonder if Vulkan support will find its way into currently shipping handsets.
As Qualcomm points out in its press release on the news, the Vulkan API will bring some important and groundbreaking changes to the mobile space.
- Explicit control over GPU operation, with minimized driver overhead for improved performance;
- Multi-threading-friendly architecture to increase overall system performance;
- Optimal API design that can be used in a wide variety of devices including mobile, desktop, consoles, and embedded platforms;
- Use of Khronos’ new SPIR-V intermediate representation for shading language flexibility and more predictable implementation behavior;
- Extensible layered architecture that enables innovative tools without impacting production performance while validating, debugging, and profiling;
- Simple drivers for low-overhead efficiency and cross vendor portability.
Vulkan API support is being added to Qualcomm's development tools suite this week as well.
“We are pleased to have contributed to the definition of Khronos’ new Vulkan API. Qualcomm Technologies will be among the first to ship conformant Vulkan drivers, starting with Snapdragon 820’s embedded Adreno 530 GPU, and subsequently with our Adreno 4xx series GPUs. Vulkan enables the next generation of graphics performance by adding multi-threaded command buffer generation and explicit control of advanced graphics capabilities within Adreno GPUs,” said Micah Knapp, director of product management, Qualcomm Technologies, Inc. “In the coming days, we anticipate supporting Vulkan in the Snapdragon developer tools including Snapdragon Profiler and the Adreno SDK, to help application developers take advantage of this outstanding new API when creating graphics and compute applications for smartphones, tablets, VR HMDs and a variety of other types of devices that use Snapdragon processors.”
A quick look at the Khronos page listing companies with Vulkan conformant drivers shows Qualcomm on the short list, meaning it has provided the standards body with a driver that has passed its first level of certification. With its emphasis on efficiency, the Vulkan API and Qualcomm's early integration could be the most important place that the API ends up. In a technology field where battery life and performance must balance unlike anywhere else, getting this new implementation of graphics and compute could push mobile devices forward quickly.

The mobile processors that were previously known as the Snapdragon 618 and the Snapdragon 620 are now known as Snapdragon 650 and Snapdragon 652, respectively. This is not how we typically see products rebranded. Normally, such as the desktop GPU market, individual products are carried between generations, and their model number is incremented to reflect that. This case is the exact opposite: Qualcomm feels that the new products are numbered too similar to existing models, so they're widening the gap between them.
An SoC is only useful if it is installed in a compelling device, though. While I would hope that these sorts of branding changes influence consumers more than device manufacturers, there exists a part of me that wonders how much this rebranding will affect their amount of design wins. You would think that bumping a model number up a few digits wouldn't affect experimentation at Samsung, LG, or other phone companies. Yet, it might, and that would be interesting to see. Either way, it should affect the semi-enthusiast phone users who buy based on breakdowns of tech specs.
Introduction and CPU Performance
We had a chance this week to go hands-on with the Snapdragon 820, the latest flagship SoC from Qualcomm, in a hardware session featuring prototype handsets powered by this new silicon. How did it perform? Read on to find out!
As you would expect from an all-new flagship part, the Snapdragon 820 offers improvements in virtually every category compared to their previous products. And with the 820 Qualcomm is emphasizing not only performance, but lower power consumption with claims of anywhere from 20% to 10x better efficiency across the components that make up this new SoC. And part of these power savings will undoubtedly come as the result of Qualcomm’s decision to move to a quad-core design with the 820, rather than the 8-core design of the 810.
So what exactly does comprise a high-end SoC like the Snapdragon 820? Ryan covered the launch in detail back in November (and we introduced aspects of the new SoC in a series of articles leading up to the launch). In brief, the Snapdragon 820 includes a custom quad-core CPU (Kryo), the Andreno 530 GPU, a new DSP (Hexagon 680), new ISP (Spectra), and a new LTE modem (X12). The previous flagship Snapdragon 810 used stock ARM cores (Cortex-A57, Cortex-A53) in a big.LITTLE configuration, but for various reasons Qualcomm has chosen not to introduce another 8-core SoC with this new product.
The four Kryo CPU cores found in the Snapdragon 820 can operate at speeds of up to 2.2 GHz, and since is half the number of the octo-core Snapdragon 810, the IPC (instructions per clock) of this new part will help determine how competitive the SD820's performance will be; but there’s a lot more to the story. This SoC design placed equal emphasis on all components therein, and the strategy with the SD820 seems to be leveraging the capability of the advanced signal processing (Hexagon 680) which should help offload the work to allow the CPU to work with greater efficiency, and at lower power.
Cat 12 Modem, Wi-Fi Adaptive Calling
If you have been following PC Perspective over the last several months it would be hard to miss news about the upcoming release of Qualcomm's latest flagship SoC for smartphones and tablets, the Snapdragon 820. Beginning in early August with discussion of the Adreno 5xx GPU architecture, followed by information covering the Hexagon 680 DSP (digital signal processor) and then details on the LTE modem in the SoC (the X12), and ending with information on the Kryo CPU cores, the release of the Snapdragon 820 processor has been drawn out if nothing else.
The emphasis on distribution of data was likely at attempt to rebuild trust with the enthusiast consumer, media and even the OEMs, as the launch of the Snapdragon 810 was troubled by overheating concerns and second revisions. Several high impact flagship smartphone used the SoC,
including the LG G4 (correction: G4 shipped with the Snapdragon 808, while the HTC One M9, OnePlus 2, Sony Xperia Z5 and others use the 810) but with Samsung moving away from Qualcomm parts to its own designs, the processor didn't see nearly the ubiquitous adoption that we had expected and witnessed in previous generations.
Qualcomm invited some media and analysts out to New York this week to take the cover off of the Snapdragon 820 completely, at least as far as features are concerned. We still were not able to get to the meat of the details surrounding the CPU / Kryo implementation or architectural improvements, but we are promised those would be coming closer to product availability in 2016. Instead, Qualcomm wanted to show off the consumer benefits that phones and tablets based on Snapdragon 820 could feature (based on OEM implementation); that means lots of demos, lots of time with product and feature managers.
A third primary processor
As the Hot Chips conference begins in Cupertino this week, Qualcomm is set to divulge another set of information about the upcoming Snapdragon 820 processor. Earlier this month the company revealed details about the Adreno 5xx GPU architecture, showcasing improved performance and power efficiency while also adding a new Spectra 14-bit image processor. Today we shift to what Qualcomm calls the “third pillar in the triumvirate of programmable processors” that make up the Snapdragon SoC. The Hexagon DSP (digital signal processor), introduced initially by Qualcomm in 2004, has gone through a massive architecture shift and even programmability shift over the last 10 years.
Qualcomm believes that building a balanced SoC for mobile applications is all about heterogeneous computing with no one processor carrying the entire load. The majority of the work that any modern Snapdragon processor must handle goes through the primary CPU cores, the GPU or the DSP. We learned about upgrades to the Adreno 5xx series for the Snapdragon 820 and we are promised information about Kryo CPU architecture soon as well. But the Hexagon 600-series of DSPs actually deals with some of the most important functionality for smartphones and tablets: audio, voice, imaging and video.
Interestingly, Qualcomm opened up the DSP to programmability just four years ago, giving developers the ability to write custom code and software to take advantages of the specific performance capabilities that the DSP offers. Custom photography, videography and sound applications could benefit greatly in terms of performance and power efficiency if utilizing the QC DSP rather than the primary system CPU or GPU. As of this writing, Qualcomm claims there are “hundreds” of developers actively writing code targeting its family of Hexagon processors.
The Hexagon DSP in Snapdragon 820 consists of three primary partitions. The main compute DSP works in conjunction with the GPU and CPU cores and will do much of the heavy lifting for encompassed workloads. The modem DSP aids the cellular modem in communication throughput. The new guy here is the lower power DSP in the Low Power Island (LPI) that shifts how always-on sensors can communicate with the operating system.

Despite the success of the Snapdragon 805 and even the 808, Qualcomm’s flagship Snapdragon 810 SoC had a tumultuous lifespan. Rumors and stories about the chip and an inability to run in phone form factors without overheating and/or draining battery life were rampant, despite the company’s insistence that the problem was fixed with a very quick second revision of the part. There are very few devices that used the 810 and instead we saw more of the flagship smartphones uses the slightly cut back SD 808 or the SD 805.
Today at Siggraph Qualcomm starts the reveal of a new flagship SoC, Snapdragon 820. As the event coinciding with launch is a graphics-specific show, QC is focusing on a high level overview of the graphics portion of the Snapdragon 820, the updated Adreno 5xx architecture and associated designs and a new camera image signal processor (ISP) aiming to improve quality of photos and recording on our mobile devices.
A modern SoC from Qualcomm features many different processors working in tandem to impact the user experience on the device. While the only details we are getting today focus around the Adreno 530 GPU and Spectra ISP, other segments like connectivity (wireless), DSP, video processing and digital signal processing are important parts of the computing story. And we are well aware that Qualcomm is readying its own 64-bit processor architecture for the Kryo CPU rather than implementing the off-the-shelf cores from ARM used in the 810.
We also know that Qualcomm is targeting a “leading edge” FinFET process technology for SD 820 and though we haven’t been able to confirm anything, it looks very like that this chip will be built on the Samsung 14nm line that also built the Exynos 7420.
But over half of the processing on the upcoming Snapdragon 820 fill focus on visual processing, from graphics to gaming to UI animations to image capture and video output, this chip’s die will be dominated by high performance visuals.
Qualcomm’s lists of target goals for SD 820 visuals reads as you would expect: wanting perfection in every area. Wouldn’t we all love a phone or tablet that takes perfect photos each time, always focusing on the right things (or everything) with exceptional low light performance? Though a lesser known problem for consumers, having accurate color reproduction from capture, through processing and to the display would be a big advantage. And of course, we all want graphics performance that impresses and a user interface that is smooth and reliable while enabling NEW experience that we haven’t even thought of in the mobile form factor. Qualcomm thinks that Snapdragon 820 will be able to deliver on all of that.
