Nucleus RTOS is a real-time operating system (RTOS) offered by the Embedded Software Division of Mentor Graphics for various central processing unit (CPU) platforms. Nucleus RTOS is embedded software and is in an estimated 2.11 billion devices worldwide.
Development is typically done on a host computer running Windows or Linux. Applications are cross compiled to run on various target CPU architectures and tested using the actual target boards or in simulation environment.
The Nucleus RTOS is designed for deeply embedded systems applications including consumer electronics, set-top boxes, cellular phones, and other portable and handheld devices. For limited memory systems Nucleus RTOS can be scaled down to a memory footprint as small as 13 KB for both code and data.
