With Eclipse Foundation as the new home, Azure RTOS becomes Eclipse ThreadX. For more information, see the following pages:
ThreadX is an advanced Real-Time Operating System (RTOS) designed specifically for deeply embedded applications. Among the multiple benefits ThreadX provides are advanced scheduling facilities, message passing, interrupt management, and messaging services. ThreadX has many advanced features, including its picokernel architecture, preemption-threshold scheduling, event-chaining, and a rich set of system services.
