Overview

HW-RTOS is a hardware real-time OS. HW-RTOS realizes excellent real-time performance with low overhead compared to conventional software RTOS implementations. It supports semaphore, event flags, and about 30 other standard APIs, and enables fast, consistent execution time and interrupt response. This enables a worst-case execution time to be specified, which facilitates the design of real-time systems.
