Constructing a heterogeneous real-time system

The construction of a real-time system on heterogeneous hardware platforms, forces one to make choices on which programming language, operating system, development process and application programmers interface to use. The application (a micro-satellite) requirements state that the system must be dependable in a remote and harsh environment such as space. This paper details the choices made and the experience gained from living with the choices made in the development of a micro-satellite and its associated ground support. The emphasis is on simple solutions throughout. The simple solution is important for the verification and validation of the complete system.<
