Google today revealed the Pixel Visual Core, a custom-designed co-processor that is built into every Pixel 2 and Pixel 2 XL smartphone. The Image Processing Unit has eight cores, each with 512 arithmetic logic units (ALUs) that can handle some three trillion calculations per second. Google claims the Pixel Visual Core with HDR+ can run five times faster and at less than one-tenth the energy than running directly on the application processor. The Pixel Visual Core is laying dormant for the time being, but Google says it will turn the co-processor on soon. Google created advanced software to manage the Pixel’s ability to capture rich photos and it wants to extend that to other photo apps. The Pixel Visual Core will eventually allow third-party apps to use the Pixel’s HDR+ technology. Google plans to enable the Pixel Visual Core as a developer option in the developer preview of Android Oreo 8.1 (MR1) in the coming weeks. Later, Google will let third-party camera apps access it using the Android Camera API, giving them access to the Pixel 2’s HDR+ technology. The end result should be much better photos on the Pixel 2 and Pixel 2 XL when using photo apps other than the stock camera.
