Nucleus RTOS

Nucleus OS is a real-time operating system (RTOS) and toolset created by the Embedded Systems Division of Mentor Graphics for various central processing unit (CPU) platforms. Nucleus OS is part of an embedded solution with a 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.

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