Design patterns, which encapsulate common solutions to the recurring design problems, have contributed to the increased reuse, quality and productivity in software design. We argue that hardware design patterns could be used for customizing and integrating the Intellectual Property (IP) components into Systemon-Chip designs. We formulate the role of design patterns in HW design, and describe their implementation using metaprogramming. We propose a Wrapper design pattern for adapting the behavior of the soft IPs, and demonstrate its application to the communication interface synthesis.

Abstract:We discuss the application of the metaprogramming techniques for soft IP design. Two metaprogramming paradigms are considered: the internal (using capabilities of the single language) and external (based on the usage of the target language and external metalanguage simultaneously) ones. The novelty of our approach is that we apply the concept of the multi-dimensional separation of concerns implemented via metaprogramming for the design of parameterized soft IPs for embedded systems in order to achieve higher flexibility, reusability and customizability.
