Nucleus RTOS is a real-time operating system (RTOS) and full-featured toolset created by the Embedded Systems Division of Mentor Graphics for various CPU platforms. Nucleus RTOS is part of a complete embedded solution with a full complement of embedded middleware available.

Development is typically done on a "host" machine running Windows or Linux. Target applications can be compiled to run on various "target" CPU architectures and tested using the actual target boards, simulators or via the "host" using EDGE SimTest.

The Nucleus RTOS is designed for embedded applications including consumer electronics, set-top boxes, cellular phones, and other portable and handheld devices. For limited memory systems Nucleus RTOS can be scaled to a footprint as small as 13 KB for both code and data.

The small footprint is the main reason for using Nucleus. Nucleus RTOS is a proven Operating syetem.
