				Summary The objective of the proposed experiment is twofold: first to develop a low-power co-design methodology for safety critical applications and a supporting design environment and second to develop, using the proposed methodology and design environment, a low power Application Specific Instruction set Processor (ASIP) that realises the control unit of a portable infusion pump system, used in regulated continuous infusion of medicines in patient. The ASIP will lead to improved features demanded by the market and at the same time it will reduce the overall power consumption of the infusion pump system (including the motor consumption). The proposed methodology aims mainly at a) the analysis of safety standards requirements and the determination of the safety mechanisms that will be implemented, b) the development of strategies for implementation of safety mechanisms, c) the introduction of power optimisation techniques for both hardware and software implementation of safety critical tasks and d) the development of strategies for power-efficient assignment of safety-critical mechanisms to hardware or software components of heterogeneous architectures. The COSAFE co-design methodology will be exploited in the development of both the ASIP and the application software, aiming at the minimisation of the overall system power consumption and therefore enhancing the features of next-generation infusion pumps. Objectives The determination of safety mechanisms and their hardware/software implementation The development of strategies for power efficient assignment of safety critical mechanisms to hardware or software The establishment of a co-design environment for low-power safety-critical designs The design and implementation of a low-power, safety-critical ASIP which realises the control unit of a portable infusion pump system Participants Micrel Ltd.
