Hardware/Software Partitioning for Automotive Multiplex Systems

When integrating Class B multiplexing into automotive systems, cost-effective solutions will require an optimal partitioning of the multiplex protocol between hardware and software. The system designer is confronted with making tradeoffs based upon application through-put requirements, device availability, and cost goals. This report discusses a model for determining the system software/hardware partitioning. The model is then applied to a sensor node application to provide further insight.
