Next Generation iPhones to Get New R1 Coprocessor Codenamed 'Rose'

Apple is planning to add a new R1 coprocessor, codenamed 'Rose', to its next generation iPhones, reports MacRumors.

A leaked internal build of iOS 13 reveals that the R1 coprocessor is similar to the M-series motion coprocessor. It helps inform iOS about where the iPhone is located and where it's headed, offloading the task from main system processor. However, the R1 integrates many more sensors to produce a more accurate location. These include the compass, gyroscope, accelerometer, barometer, and microphones.

The Rose coprocessor will add support for an inertial measurement unit (IMU), Bluetooth 5.1 features, ultra-wideband (UWB) and camera (including motion capture and optical tracking) sensor data to not only tell where the device is but also fuse this sensor data together to find lost Apple Tags and aid in the processing of People Occlusion from ARKit. Given the overlap in sensor data collection and processing the Rose coprocessor may replace the M-series motion coprocessor.


By combining data from the R1 and the Angle of Arrival (AoA) and Angle of Departure (AoD) features of Bluetooth 5.1, Apple will likely be able to find Apple Tags with a high degree of accuracy.

Apple is set to unveil next generation iPhones and the new A13 processor at a press event tomorrow. Please follow iClarified on Twitter, Facebook, or RSS for updates.
