The launch of Snapdragon VR SDK creates a first-class virtual reality experience

A few weeks ago, the White House posted a photo of US President Obama experiencing VR on Instagram. In the photo, President Obama looked up at the sky and visited Yosemite National Park in virtual reality. One of his assistants was still Work at the desk on the side. This photo quickly became popular on the Internet, with an instant hits of 600,000 times, making more people fascinated by this technology, which shows that VR is the hottest topic.

With the emergence of more and more VR terminal devices, VR is no longer the unattainable future in our mouth, and better VR experiences are gradually coming into our lives. As a leading company in mobile terminal chips, Qualcomm's Snapdragon chips are also continuing to follow up in the VR field, using solid technology to promote VR towards an immersive and mobile future. The following author will take you to reveal the VR black technology of this Xiaolong core. With these black technologies, the existing VR experience may be just the tip of the VR iceberg.

Snapdragon core heterogeneous design

Take the Snapdragon 820 processor as an example. This chip has built-in Adreno 530 GPU, Hexagon 680 DSP and Kryo CPU. The performance of the three is in the leading position in the industry, and together they form a heterogeneous computing unit. This heterogeneous design coordinates the division of labor between the three through the underlying system, and each part can conduct effective data exchange, effectively reduce processing delays, improve computing efficiency, and bring a more stable and reliable immersive VR experience.

With the development of VR today, the pursuit of high resolution is the main trend, especially when the distance between the human eye and the screen is only a few centimeters, 4K resolution can meet our visual needs, but high resolution brings The data processing pressure is huge, and extremely high requirements are put forward for the performance of the GPU. The built-in Adreno 530 GPU of the Snapdragon 820 has outstanding performance and can achieve high frame rate insertion under 4K to ensure smooth pictures. In addition, Adreno 530 GPU also integrates advanced image enhancement technology to effectively improve image quality through algorithms such as noise reduction, resolution interpolation, and HDR processing.

In addition to the pursuit of realistic visual effects, more important is the coordination of the senses. For example, when we make an action, the sensor can capture data in time, the picture in front of us can be switched smoothly, and the sound in the ear can be changed accordingly to achieve an immersive experience. Behind this series of actions, Hexagon 680 DSP contributed a lot. It is mainly responsible for processing the digital signal of the sensor, working in conjunction with the virtual rendering of the Adreno 530 GPU, making the sensor, image, and sound effects parallel processing, effectively reducing the delay, and making the VR immersive more outstanding.

Obvious advantages of wireless transmission

With the development of VR, the mobility of VR has also become another trend. People hope to wear VR glasses to experience the charm of VR anytime and anywhere. After all, no one wants to experience VR while dragging a long braid behind. However, the amount of data of several gigabytes of VR resources at every turn puts forward higher requirements on the transmission rate and delay, which requires advanced wireless transmission solutions to solve, and this is the strength of Qualcomm Snapdragon. The Snapdragon 820 supports 802.11ad, which is Wi-Fi in the 60GHz frequency band. This technology can expand the bandwidth to an astonishing 7Gbps, increase the transmission rate while effectively reducing the delay. In addition, MU-MIMO non-congestion Wi-Fi technology is also supported accordingly, so as to achieve faster Wi-Fi connections. This means that the wireless VR device powered by the Snapdragon 820 has an experience that is definitely not inferior to traditional devices.

At present, such a product is already available. Domestic manufacturer Pico Xiaoniao released the first Snapdragon 820 VR all-in-one machine-Pico Neo in April this year. Just past IFA 2016, Qualcomm also announced the launch of the Snapdragon VR820 VR headset. These devices are different from current products. They contain a lot of advanced hardware in a compact size. They rely on the performance of the Snapdragon 820 to protect them. Without other hosts and peripherals, you can experience the fantasy virtual world by wearing VR glasses.

Snapdragon VR SDK launched

In March of this year, Qualcomm launched the Snapdragon VR SDK. The Snapdragon VR SDK supports a number of critical new technologies for the best VR user experience, including: DSP sensor fusion, fast photon movement, stereo rendering with lens correction, VR layers, and power management. Among them, the DSP sensor fusion technology allows developers to use the Hexagon 680 DSP built in the Snapdragon 820 to obtain sensor data, and then perform predictive head position processing to create an immersive experience with better responsiveness. Fast photon movement technology provides fast 3D image rendering through asynchronous time warping and single-display buffering, which can reduce latency by up to 50%.

The launch of the Snapdragon VR SDK creates a first-class virtual reality experience

It is foreseeable that the launch of the Snapdragon VR SDK enables developers to fully tap the potential of the Snapdragon core and create a first-class virtual reality experience. In addition, Qualcomm, as an upstream company in the industry, will also open up key information such as the reference design, hardware design, and software drivers of Snapdragon VR devices, thereby simplifying the design steps and development costs of VR devices, allowing developers to focus more on VR content. The research and development of Snapdragon will give more fresh and interesting experiences to Snapdragon VR, and jointly build a prosperous mobile VR ecosystem.

Promote the development of mobile VR

As mobile terminals play an increasingly important role in life, VR is also shifting from mainframes and PCs to mobile phones and VR all-in-ones. Qualcomm Snapdragon has played an active role in it. First of all, Qualcomm Snapdragon processor has absolute performance, so that the mobile terminal VR experience is not compromised. Secondly, thanks to Qualcomm's advanced communication technology, VR equipment is not bound by wires, and the experience is better. Finally, the Snapdragon processor has a high level of integration, and Qualcomm has also disclosed its VR design, making it easier to build mobile VR devices, and the cost is better controlled. Consumers can get an excellent VR experience at a relatively low cost. . In the future, in gaming, 360-degree video, interactive education, and entertainment scenarios, we look forward to more surprises in mobile VR led by Qualcomm Snapdragon.

85W Macbook Charger

The 85W Macbook Charger MagSafe 1 or MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.

When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.

Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.

This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
