Real-Time OS deployed on more than 3 billion devices
The Nucleus® RTOS is deployed in over 3 billion devices and provides a highly scalable micro-kernel based real-time operating system designed for scalability and reliability.System reliability can be improved using lightweight memory partitioning support that can function with or without MMU/MPU assisted protection in systems spanning the range of aerospace,industrial,and medical applications.Developers can make full use of multi-core solutions across the spectrum of Microcontroller and Microprocessor SoCs using SMP and AMP configurations to integrate multiple operating systems.To meet the power requirements of todays advanced designs,engineers can ease development with integrated power management in Nucleus that includes support for DVFS,deep sleep modes,and power/clock gating.
Key RTOS Features and Benefits
- Stable deterministic kernelwith a small memory footprint (as low as 2 kb)
- Process modelfor memory partitioning to increase product reliability with and without MMU
- Power management APIsfor low-power design
- Connectivity (CAN,I2C,SPI)
- USB 2.0 and USB 3.0
- Multicore Supportincludes xAMP and SMP support with rpmspg over virtIO and MCAPI for inter-process communication
Nucleus RTOS is available in the following configurations:
