Building on the Nucleus RTOS (real-time operating system), Mentor Graphics has released the third generation version which provides built-in power management capabilities claimed to seamlessly use hardware features such as DVFS (dynamic voltage and frequency scaling), for power-conscious, battery- powered applications. New connectivity features are a certified IPv6 Ready networking stack and security protocols. There are also Wi-Fi, Bluetooth, and Zigbee wireless communications options to speed time-to-market in developing connected devices. The RTOS also supports ARM, MIPS, Power PC, Stellaris, and SuperH architectures and processor families, as well as DSPs and soft processor cores on FPGAs. There is also a new configuration technology to customise system requirements. Through single API calls, application developers can use the power management to change system states or switch operating points in a portable and re-usable way. This inclusion means that there is no implementing of or need to maintain complex scenarios within the application code. The RTOS is part of the Embedded Nucleus ReadyStart platform, integrating software IP, developer tools, and services. It includes Embedded Sourcery CodeBench technology, GNU-based IDE, and the company's Embedded Inflexion UI tool to dynamically create a 2D or 3D user interface.
