In this paper, we propose to implement hybrid operating systems based on two-level hardware interrupts. We analyze and model the worst-case real-time interrupt latency for RTAI and identify the key component for its optimization. Then, we propose our methodology to implement hybrid operating systems with two-level hardware interrupts by combining the real-time kernel and the time sharing OS (Operating...
In this paper, we propose to implement hybrid operating systems based on two-level hardware interrupts. To separate real-time and non-real-time hardware interrupts by hardware, we show that it is easier to build up hybrid systems with better performance. We analyze and discuss the key issues for implementing a hybrid system based on this and implement a hybrid system called RTLinux-THIN (Real-Time...
