"Linux on ITRON": a hybrid operating system architecture for embedded systems

The hybrid operating system approach which is to combine a general-purpose operating system with a real-time operating system is a promising approach to satisfy the real-time property, which is usually required or embedded systems. The paper describes a hybrid operating system architecture called "Linux on ITRON," which is a combination of Linux and a real-time kernel based on the /spl mu/ITRON Specification. A problem raised in the design of "Linux on ITRON" and its solutions are also discussed.
