Windows CE
Windows CE, optimized for devices that have minimal storage means basically that a kernel may run in under a megabyte of memory. Devices are often configured without disk storage, and may be configured as a “closed” system that does not allow for end user extension, meaning that it can be burned into the devices ROM. Windows CE conforms to the definition of a real-time operating system, with a deterministic interrupt latency. It supports 256 priority levels and uses priority inheritance for dealing with priority inversion. The fundamental unit of execution is the thread. This helps to simplify the interface and improve execution time. That being said, you cand find versions of it working on various devices, small phones, and pocket pc's.
