Qualcomm Intros SD845-Based Mobile VR Reference Design

Snapdragon VR reference design 1

Qualcomm has just introduced its VR headset reference design, ahead of the Mobile World Congress (MWC) in Barcelona. This new reference design is based on the company’s most powerful processor to date, the Snapdragon 845, which was announced at the end of last year. This new system will bring a couple of new features to the table, including room-scale tracking and foveted rendering, both of which will probably come in handy to both developers and VR gadget manufacturers, and we’ll talk about both of those in a minute.

Thanks to the company’s Snapdragon 845 processor, this new system is 30 percent faster and uses 30 percent less power than the Snapdragon 835-based version. The Snapdragon 835 is currently being used in a number of VR headsets, like the HTC Vive Focus and the Lenovo Mirage Solo, for example, and the Snapdragon 845 will probably fuel a number more in 2018, though it remains to be seen which OEMs will take advantage of it. By utilizing the Snapdragon 845, VR devices will be able to support even higher-res displays, Qualcomm actually said that the Snapdragon 845 has “more than twice as much display throughput compared to the Snapdragon 835 mobile platform,” which is a considerable upgrade, no matter what way you’re looking at it. What does this mean for VR headsets? Well, it means that VR headset manufacturers will basically be able to include two 2K displays in a single VR headset, and a single Snapdragon 845 chip will be able to fuel them both without a problem.

The reference design Qualcomm introduced comes with four cameras, and two of those cameras are facing backwards, to the face of the person using the VR headset, in order to track its pupils. Based on the collected info, the Snapdragon 845’s GPU renders higher quality graphics at the points the user is looking towards, in real time, of course. This is actually called ‘Adreno Fovetation’, by the company, in case you were wondering. Qualcomm’s new platform will also support Roomscale tracking, by using the 6-DoF (Degrees of Freedom) tracking with SLAM (Simultaneous Localization and Mapping). In plain terms, the new platform will pay attention to your body and the room you’re in, and it will help you detect obstacles in front of you.
