Last April, Rockchip published a roadmap to 2020 with processors such as RK3588 Cortex-A76/A55 or RK3530 quad-core Cortex-A55 SoCs. Part of the roadmap was also Rockhip RK2108 Arm Cortex-M4 microcontroller with an Audio DSP which did not get as much coverage.
The company has now announced RK2108 based smart docks that convert tablets into smart display / speakers so that they can be waken-up and controlled by voice commands.
Rockchip RK2108 audio MCU supports A/D audio interface, MIPI DSI/MCU LCD interface and USB2.0 interface, and comes with the following key features:
- Built-in audio DSP for voice/audio signal processing
- Audio pre-processing, active noise reduction, AEC, etc… for improved voice recognition
- Customizable wake-up words and offline instructions
- Ultra-low power consumption in both standby and operating modes
The RK2108 smart dock pictured above connects to compatible Android tablets over USB or Bluetooth, and turns those into smart display products that can handle voice commands more accurately and at lower power.
If you’d like more details about RK2108 MCU and the smart dock solution, there isn’t really more information online. So if you have a product idea you’d need to contact Rockchip or one of their distributors.
I had never seen this type of smart audio dock for tablets, but it turns out Lenovo Smart Tab P10 2-in-1 tablet & smart dock with Amazon Alexa does something similar based on another solution. You can watch what to expect from this type of product in the video below.
