An operating system (OS) is software that supports essential computer functions by managing software and hardware in a computer system. An embedded OS is typically tailored for a specific system and is usually as small as is necessary to do its job. You can find OSes in smartphones, routers, smart watches, game consoles, Alexa/Google Home, and many other devices. Zephyr™ is a microcontroller OS that has been developed primarily for the Internet of Things (IoT) and supports multiple architectures. Zephyr has roots in a Real-Time OS (RTOS) created by Wind River in 2015, called the “Rocket OS,” which was designed for resource-constrained systems. In 2016, WindRiver transferred Rocket OS into the Zephyr project managed by the Linux Foundation as open source.
