Service Based Component Design Approach for Flexible Hardware/Software Interface Modeling

This paper describes a service-based model enabling systematic design and global simulation environments for SoC design. This model, called Service Dependency Graph (SDG) allows modeling of complex, customized (application-specific) interfaces. We also present a model generator that can automatically build hardware/software interfaces based on service and resource requirements described by the SDG. This approach has been applied successfully on the design of a Software Defined Radio application. The results show the effectiveness of the proposed approach in modeling complex interfaces. Additionally the SDG seems to be an excellent intermediate representation for the design automation of hardware software interfaces.
