iPhone 11’s A13 Chip Will Feature New ‘Rose’ Coprocessor With Additional Sensors

Apple’s upcoming A13 series chip which will power the iPhone 11 series will feature a new coprocessor codenamed “Rose” and “R1.”

There’s no word on what the final name of the chip will be for marketing purposes, though it is possible that Apple could refer to it as R13. The R1 coprocessor is similar to the M-series motion coprocessor like the M12 found inside the A13 Bionic chip.

The motion coprocessor processes data received from compass, gyroscope, accelerometer, and other similar sensors to identify an iPhone’s location in space. The R1 coprocessor will go a step ahead and support inertial measurement unit (IMU), ultra-wideband, camera sensor data, and more. It will use this data to more accurately identify the iPhone’s location as well as use the data from the other sensors to find lost Apple Tags.

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.

Since the Rose coprocessor is in many ways an advanced version of the motion coprocessor, it is possible that Apple has ditched the latter from its A13 Bionic chip to free up die space.

The Rose/R1 coprocessor will rely on certain Bluetooth 5.1 features like Angle of Arrival and Angle of Departure to find Apple Tags. Thus, it is possible that advanced tracking for lost Apple Tags is only available on the iPhone 11 series as older iPhones only support Bluetooth 5.0 or lower.

The A13 chip inside the upcoming iPhone 11 series will be based on TSMC’s enhanced 7nm+ EUV process. It is expected to be more efficient than TSMC’s current 7nm foundry on which the A12 Bionic is fabricated.

Apple will be unveiling the iPhone 11 series alongside the Apple Watch Series 5 and more at its ‘By Innovation Only’ event tomorrow. You can find all the details on how to watch the 2019 iPhone 11 event live over here. You can find the local start time of the iPhone 11 event here.
