Describes the [mu]ITRON 3.0 Specification, the latest version of the ITRON (Industrial) specification for use on real-time embedded systems. The book focuses on the many noteworthy features of the ITRON specification operating system but also concentrates on its open specification that achieves both real-time performance and wide adaptability. This specification will meet the need for strict cost requirements and limited hardware resources for low-end applications. The operating systems advantages lie in its maintenance and ease of expansion, allowing for its software resources to be reused effectively. The ITRON specification OS is designed to solve the usual problems and is developed for implementation on bare-bones hardware configurations. It brings to the world of low-cost embedded computer systems a revolutionary new approach to software configuration.
