µ-velOSity RTOS Description
The u-velOSity RTOS, the smallest member of Green Hills Software's range of real-time operating system families, is called "the u-velOSity RTOS". It is a C library that can be easily port to many target architectures. It is simple to use and has a clean design. u-velOSity provides a concise API that makes it easier to develop products and reduces time. This allows you to reduce costs and speed up time-to-market. Developers who want to move from standalone or no OS configurations. u-velOSity is more compatible with on-chip memory due to its compact design and minimal footprint. The execution speed is dramatically increased by removing the need to access offchip memory. u-velOSity was created to reduce the number of CPU clock cycles required to boot embedded devices that have very fast boot times. u-velOSity is the ideal RTOS for embedded devices that have high power requirements.

RTX
The Keil RTX operating system is royalty-free and deterministic. It's designed for ARM or Cortex-M devices. It allows you to create programs which perform multiple functions simultaneously and helps you create applications that are more structured and easier to maintain. Source code, royalty-free, deterministic and deterministic RTOS. Although it is possible to create real time programs without an operating system (by running one or more functions in Super-loop), there are many scheduling, maintenance and timing issues that an operating system like the Keil RX can solve. An RTOS is a better alternative to Super-loop. High-Speed real time operation with low interrupt latency. Resource constrained systems require a small footprint. Unlimited number of tasks, each with 254 priority levels. Unlimited number of mailboxes, semaphores and mutex. Multithreading and thread-safe operation support.

SCIOPTA
SCIOPTA architecture was specifically designed to deliver high real-time performance with a small footprint. High-quality optimizations have been made to optimize internal data structures, memory management, and interprocess communication. SCIOPTA is a preemptive real-time kernel. Interrupts can be handled at any time, even within the kernel. SCIOPTA, a message-based real-time operating platform, is available. To manage the resources, a powerful set of system calls can be used. Clear system designs are possible thanks to standard processes and interprocess communication. They are easy to understand, write and maintain. SCIOPTA systems can be used to facilitate teamwork in large projects because they communicate with clearly defined messages. This will dramatically reduce the time-to-market. SCIOPTA uses a message-based architecture that allows for direct message passing between processes. Messages are used mainly for interprocess communication and synchronization.
