Real-Time operating systems (RTOSes), popularized in the 1990s, provide technical benefits for a wide range of embedded andrealtime products. Some of the most important benefits include fast and small code footprint, deterministic function, broad semiconductor support, structured design approaches, and software reuse through encapsulation.
RTOSes typically have a microkernel design where the scheduler plays a central role. Building on a simple yet effective real-time scheduler enables system design precision. The decision-making factors for production systems extend beyond the technical basics. Product teams must make business, software engineering, and long-term viability considerations when choosing an RTOS.
