Cesium RTOS
Cesium RTOS represents an evolutionary leap from its predecessor, Micrium µC/OS RTOS, propelling real-time operating systems into the next generation. Cesium RTOS introduces cutting-edge advancements and enhanced capabilities, empowering embedded systems with increased performance, improved efficiency, and seamless integration.
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.

Commercial License
All Cesium RTOS components are commercially licensed. All commercial licenses are a one-time purchase that are perpetual for the life of your product and royalty-free. We use the same simple licensing model as did Micrium, based on your end-product's deployment, for establishing the commercial license costs. The following types of licenses are available for purchase:
Single Product License
A Single Product License allows you to embed a Cesium RTOS software component into one customer end-product. There is no limitation on the number of end-customer products deployed. This license is specific to the processor used and the specific name and model of the customer end-product.
Product Line License for Single CPU
A Product Line License for a Single CPU allows you to embed a Cesium RTOS software component into any number of customer end-products within a given product family. You may use only a single and specific processor type within the product family. You may deploy an unlimited number of these customer end-products within the product family.
Product Line License
A Product Line License allows you to embed a Cesium RTOS software component into any number of customer end-products within a given product family, and to deploy an unlimited number of these customer end-products within the product family.
CPU (Platform) License
A CPU-Type License allows you to embed a Cesium RTOS software component into any number of customer end-products using a single and specific processor type. You may deploy an unlimited number of these customer end-products.
Site License
A Site License allows you to embed a Cesium RTOS software component into any number of customer end-products that use any CPU, as long as the products are designed at a single site. There are no restrictions on design or quantity.
