Parallel Computing and Optimization Techniques

Many embedded, realtime operating systems are commercially available, but most are targeted at the capabilities of a particular CPU, and were designed according to the ideas of a particular implementer. Some are handicapped by inadequate functionality, others are loaded with functions in such abundance that their performance suffers. Users seeking a suitable realtime OS for a planned application system are frequently forced to develop ad hoc solutions of their own. The ITRON specification1–8 was created in answer to this situation. It specifies a realtime, multitasking OS architecture for embedded industrial applications. It was designed so that it can be implemented on a variety of microprocessors, and can fully exploit the capabilities of each. This paper discusses the design philosophy, purpose, and functions of the ITRON specification, and describes an OS developed to conform with this specification.
