When using a real-time operating system in a safety system, we need to ensure the correct function. The way and depth for proving of the functional behavior depend on the target market of the safety system. Each primary market has definitions and rules for the way to prove the correct behavior, written in standards:

The next uC/OS generation

Cesium RTOS is a full-featured embedded operating system that was originally forked from Micrium µC/OS.
The codebase is strictly developed and maintained by Weston Embedded Solutions.
It features support for TCP/IP, USB Host/Device, and Modbus, as well as a robust file system.

Real-Time Kernels

At the core of the Cesium RTOS are the Cs/OS2 and Cs/OS3 real-time kernels; highly portable, scalable, preemptive, real-time, deterministic, multitasking kernels for microprocessors, microcontrollers, and DSPs.

Offering unprecedented ease of use, the Cs/OS kernels are delivered with complete 100% ANSI C source code and in-depth documentation. They run on a huge number of processor architectures, with ports available for download.

The Cs/OS kernels allow you to adjust your system’s memory footprint based on your design requirements, saving valuable memory space.

Weston Embedded Solutions – WES, is here to help. Our team of former Micrium and Silicon Labs engineers has accumulated over 25 years of experience with the design and support of the µC/OS software suite. Weston Embedded Solutions is the embedded software expert for Micriµm’s µC/OS family of products.

Since it’s founding in 1999 as a private company, Micriµm™ and its team of engineers have offered world-class embedded software components for the most critical and demanding real-time applications. Recognized as having some of the cleanest code in the industry, with easy to understand documentation, the Micrium real-time kernels and software components have successfully been deployed in thousands of products worldwide across a broad range of industries. Micrium’s µC/OS™ kernel has been certified for use in safety-critical applications and remains a respected favorite in the medical, aerospace and industrial markets. It continues to be the RTOS of choice for engineers requiring the most reliable and trusted solution for their mission-critical applications.

In 2016 Micrium was acquired by Silicon Labs to bring RTOS expertise to the company and to integrate Micrium’s embedded software components with Silicon Labs’ wireless and MCU devices. Throughout this time, Silicon Labs continued to make available and directly support Micrium’s µC/OS embedded components across all industry embedded platforms.

Beginning in 2020, Silicon Labs made the Micrum µC/OS products available under an open-source license and discontinued externally supporting the products. With this new phase in the evolution of the Micrium µC/OS product life, WES recognizes that an open-source license creates many new product application opportunities that require a reliable, robust RTOS. We also realize that countless established and successful users of the Micrium products may require assistance with their applications.
