TizenRT lightweight RTOS for low-end IoT devices (Intro)
TizenRT is a lightweight RTOS-based platform to support low-end IoT devices. It has been commercialized in smart TV, smartphone, wearable devices (Gear S, Gear Fit), and smart home appliances. However, low-end and low-cost IoT devices, such as home appliances without display and wearable bands with a small LCD, have received less attention. The goal of TizenRT is to extend the Tizen platform device coverage to these kind of low-end devices. It is an RTOS-based lightweight platform fitting in these devices, which are typically equipped with Cortex-M/R processors with MPU, less than 2 MB RAM, and less than 16 MB Flash.
TizenRT was kicked off with TinyAra project, which was based on the NuttX kernel, in 2015. NuttX is a real-time operating system (RTOS) with an emphasis on standard compliance and a small footprint. While maintaining the kernel architecture, TizenRT has grown by building up the IPv4/IPv6 network stack, file system, lightweight database called AraStorage, device monitor, and IoT protocols, such as OCF and LWM2M. The combination of AraStorage and IoT protocols allows TizenRT to collect, store, and deliver IoT sensor data easily.
TizenRT has been commercialized in smart home appliances and various IoT devices without display since 2017. Now, TizenRT is looking forward to some intelligent features such as voice services.
