Co-Design at Work: the Ethernet Bridge Case Study

The aim of this document is to present a hardware-software co-design methodology, working through a case study of an Ethernet bridge. This co-design process starts with a system level specification based on the LOTOS formal description technique. The hardware-software partitioning approach is characterized by coarse granularity, a clustering algorithm and a cost function based on estimates at different abstraction levels. Validation accompanies each design stage.
