After Google's unveiling of its pending VR platform, it would follow that the major players in the technology field would toss various hats into the ring. We saw Intel announce a reference head mounted VR system at IDF last month called Project Alloy. Today Qualcomm takes the covers off its own reference head unit, creatively called VR820.
The reference platform is built on exactly what you would expect: a Qualcomm Snapdragon 820 SoC with the Adreno 530 graphics subsystem in place to handle 3D rendering. Thanks to the heterogeneous computing capability of the QC platform, the VR820 integrates an impressive array of data input including the standard gyro and accelerometer. VR820 adds in dual front-facing cameras to allow for spacial tracking and 6-degrees of freedom for movement (left/right, up/down and forward/backward, pitch, yaw and roll) and to integrate see-through or augmented reality applications. Most interesting to me is that the VR820 is among the first platforms to integrate internal eye tracking, ostensibly to allow for tricks like foveated rendering that allow the system to dynamically change quality levels based on where the users' eyes are actually focused.
The VR820 is a reference platform so you'll likely never see a Qualcomm-branded device on the market. Instead VR820 will be available to OEM out for product and resale as early as Q4 of this year, meaning there is a SLIGHT chance you'll see something based on this for the holiday.
Despite being built on what is essentially a smartphone, the VR820 will allow for higher performance on the CPU and GPU courtesy of the looser thermal constraints and the larger battery that will be built into the device. Qualcomm stated that they expect the device to allow for "a couple of hours" of use in it's current implementation. That doesn't mean a partner wouldn't decide to implement a larger battery to expand that time frame.
The current display in this device is a 2560x1440 single screen, though the SD820 and Adreno 530 could address two independent displays should a partner or future reference design call for it. Looks like Qualcomm switched up and implemented a 1440x1440 display per eye in this reference platform. It is an AMOLED display so you should see amazing color depth though I am a bit concerned by the 70Hz refresh rate it peaks at. Both the HTC Vive and the Oculus Rift are targeting 90Hz as the minimum acceptable frame rate for a smooth and high quality user experience. Though I will need hands-on time with the product to decide either way, I am wary of Qualcomm's decision to back off from that accepted standard.
That being said, with the low latency AMOLED screen, Qualcomm tells me the VR820 will have an 18ms "motion to photon" latency which comes in under the theoretical ~20ms maximum for an immersive experience.
The current iteration of VR820 is running Android, though other operating systems like Microsoft's Holographic OS should be compatible if the ecosystem buys in.
It's clear that the goal of untethered VR/AR is the target for mass market experiences. I personally have doubts about the capability of something like VR820 or Intel's Project Alloy to really impact the VR gaming market without being attached to much higher end processing like we see with the Rift and Vive today. More mainstream activities like movies, conferencing and productivity are within the grasp of a processor like the Snapdragon 820. But how well will it handle games that try to emulate Job Simulator or Eve: Valkyrie? Will eye tracking capability allow for higher effective resolution gaming?
There is still a lot to learn about Qualcomm's entry into the dedicated VR space with the VR820, and though pricing will obviously depend on the specifics of the OEM that licenses the design and what modifications may occur, QC thinks the reference platform as we see it here should be in the $500 ballpark.

Ever wonder how efficiently a major venue operates when it's only full of fans on game days? It turns out they don't operate all that efficiently, and the overhead is very expensive. This is where Qualcomm and OSIsoft step in, collaborating on a new “Smart Ballpark” project for San Diego's Petco Park.
“The San Diego Padres are utilizing edge intelligence gateways, powered by Qualcomm Snapdragon processors, to collect data from critical infrastructure systems and stream it in real-time to OSIsoft’s PI System in order to monitor utilities, improve operating efficiencies and drive sustainability across the team’s entire Petco Park ballpark.”
With usage monitoring for utilities (electrical and gas energy, potable and non-potable water) the Padres - San Diego’s Major League Baseball team that calls Petco Park home - see the potential to save more than 25% in the next five years.
“The edge intelligence gateways, using Snapdragon processors, connect to sensors and legacy systems throughout the ballpark using a broad range of communication methods, including wired and wireless technologies, analog and digital inputs and multiple communication protocols. These edge intelligence gateways acquire, store and stream data in real-time to the OSIsoft PI System which then presents the data to the Padres’ facilities managers using OSIsoft’s Visualization Suite and analytics, providing the operations team with deep situational awareness of everything happening in the venue.”
This is a mammoth implementation of IoT (Internet of Things), with OSIsoft’s PI system a major player on the industrial side. Qualcomm naturally needs no introduction, as the smartphone SoC maker found in so many devices across virtually all brands. Qualcomm has also worked on improving mobile data performance in large venues such as ballparks, with products like the X16 modem (expected in products starting in the second half of 2016) offering improved connections via carrier and link aggregation, and use of unlicensed spectrum.

Announced today, the Snapdragon 821 offers a modest CPU frequency increase over the Snapdragon 820, with clock speeds of up to 2.4 GHz compared to 2.2 GHz with the Snapdragon 820. The new SoC is still implementing Qualcomm's custom quad-core "Kryo" design, which is made up of two pairs of dual-core CPU clusters.
"What isn’t in this announcement is that the power cluster will likely be above 2 GHz and GPU clocks look to be around 650 MHz but without knowing whether there are some changes other than clock relative to Adreno 530 we can’t really estimate the performance of this part."
Specifics on the Adreno GPU were not mentioned in the official announcement. The 650 MHz GPU clock reported by Anandtech would offer a modest improvement over the SD820's 624 MHz Adreno 530 GPU. Additionally, the "power cluster" will reportedly move from 1.6 GHz with the SD820 to 2.0 GHz with the SD821.
No telling when this updated SoC will find its way into consumer devices, with the Snapdragon 820 currently available in the Samsung Galaxy S7/S7 Edge, LG G5, OnePlus 3, and a few others.

The only good news about this particular decryption hack requires physical access to your phone and as you should be aware once someone has your device in their hands all bets about security are off. The vulnerability exists on ARM-compatible Snapdragon system-on-chips and the TrustZone, a secure part of the chip which runs outside of the operating system and passes information pertaining to the encryption on your phone via the Qualcomm Secure Execution Environment.
It is possible to to exploit an Android kernel security vulnerability to load your own QSEE application which can then query the TrustZone for your unencrypted blob and RSA key. From there it is simply a matter of brute forcing the phones PIN or password which then allows you access to all the encrypted data on the device. The Register explains not only the vulnerability but also how TrustZone and KeyMaster work on your devices in this article.
"Essentially, if someone seizes your Qualcomm Snapdragon-powered phone, they can potentially decrypt its file system's contents with a friendly Python script without knowing your password or PIN."

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.
