Abstract :
A fault-tolerant system architecture for medical applications in which the processors and software interactions are treated in a unified manner is proposed. An overview of the requirements of such a system, which includes fully testable processors that are self-checking and which can execute multiversion software in parallel, is provided. The system will facilitate the interactions and provide for performance and fault monitoring, adjudication of outputs, and dynamic system reconfiguration. An implementation plan for the processor is presented
