Nucleus Operating System

Reduce your bill of materials costs

Like all of Nucleus operating system, the Nucleus Kernel source code is provided at no additional cost. Its small size does not stress system resources (memory, cache, and CPU cycles) so you can minimize hardware costs while maximizing performance.

Designed-in deterministic, real-time response

Real-time execution requires deterministic, fast interrupt response and fast context switching. Nucleus Kernel utilizes a two-layer interrupt mechanism that minimizes the amount of time spent in critical section.

Develop with familiar APIs

ANCI C, POSIX real-time extensions, C++ for real-time, and micro-ITRON APIs are all available.

Guaranteed real-time responsiveness in multicore systems

Suitable for asymmetric, symmetric, and threaded architectures, Nucleus Inter-Processor Communications (IPC) is a flexible, high-speed, zero-copy mechanism for synchronization and communication on multicore chips.

A memory management unit (MMU) at your fingertips

Increase quality and eliminate embarrassing recalls by finding bugs early. Nucleus MMU enables the MMU hardware and allows for a wide variety of services to be protected, from tasks to system objects to the entire kernel. Reduce your time-to-market by using Nucleus MMU as a debugging tool during development as well as for protection in your final product. As with all Nucleus products, Nucleus MMU applications are highly portable to any new CPU architecture.

Dynamically load, unload, and execute your application on a running target

The Nucleus RTOS DDL API allows you to easily introduce new sections of code into your existing application from a remote development host. It also provides for software updates in your product after deployment. Using Dynamic Download, you can speed up your download time and eliminate the overhead associated with rebuilding and linking your entire application.

Maximize team productivity

This full-featured, yet flexible operating system offers multiple services in an easy-to-use modular format. You only use what you need, minimizing overhead. Then, complete your design with EDGE, Mentor’s integrated, Eclipse-based tool suite that allows you to work in a single environment, streamlining the development process to final completion.

Mitigate risks and reduce design complexity

Mentor’s complete portfolio of solutions eliminates the need to integrate a collection of software from different vendors. Plus, technical support will be swift and efficient, and complications vastly reduced.

Reduce time to market

Get to market faster with a better product by using Nucleus RTOS's proven portfolio of embedded tools. By building on the foundation of an application-ready platform, your developers can focus on the value-add that differentiates your product in the marketplace.

Improve your ROI

Delivering a quality product to market within the prescribed time horizon is one thing; doing it under budget is another. Nucleus solutions are tuned for superior performance in resource-constrained environments. Nucleus delivers an optimal experience to end users without having to super-size a processor and/or memory. You get a superior product at lower cost with higher margins.

Cost-effective licensing

The Nucleus licensing model is the most cost-effective option for adding a quality, commercial operating system to your offering.

APIs are easy to learn and use

Nucleus RTOS offers APIs that are consistent, intuitive, easy to use, and easy to learn. You’ll receive complete documentation to ensure that you’re productive from day one.
