 the requirements of Internet of Things (IoT) devices and other embedded
 devices. These requirements include a very low memory footprint (on the order
 of a few kilobytes), high energy efficiency, real-time capabilities, support
 for a wide range of low-power hardware, communication stacks for wireless and
 communication stacks for wired networks.
