Apple first introduced M-series coprocessors in 2013. The M-series coprocessors collect sensor data from accelerometers, gyroscopes and compasses and offload the processing of these data from the main CPU to reduce battery drain. Today, Macrumors reported that Apple is planning to introduce ‘R-series’ coprocessor starting with the upcoming iPhones. Apart from the sensor data support by the current M-series coprocessors, the R1 coprocessor can process new types of data including inertial measurement unit (IMU), Bluetooth 5.1 features (Angle of Arrival and Angle of Departure), ultra-wideband (UWB) and camera (including motion capture and optical tracking).
The R1 coprocessor in the upcoming iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max will enable advanced AR features including People Occlusion and support for Apple Tags. Through Apple Tags and R1 coprocessor, you will be able to find your lost items in AR mode.
