Nucleus RTOS
Encyclopedia
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 an embedded software solution and is in an estimated 2.11 billion devices worldwide.
Development is typically done on a host computer running Windows or Linux. Applications are 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 embedded systems applications including consumer electronics, set-top box
es, 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.
Example devices using Nucleus products are as follows:
Real-time operating system
A real-time operating system is an operating system intended to serve real-time application requests.A key characteristic of a RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is jitter...
