Rapid Software Driven Design of Arm Based Embedded Shipborne Communication Device

This paper presents the details and experiences gained in software driven design of the shipborne communication device. Prior to codesign techniques emerged in 1990's the traditional embedded design methodology involved problem specification, separate hardware and software specification, and integration and the system test as the final step in the embedded device design. Such an approach can potentially lead to numerous iterations and increased cost of the development cycle because some tests cannot be performed without fully functioning software. Codesign techniques, on the other hand, involve steps such as co- specification, co-synthesis and co-verification of hardware and software. Furthermore, it is well known that when designing embedded device the most working hours are spent on software design. However, nowadays there is a large number of freely-available software tools and libraries available which greatly facilitate the software design. Therefore, it is suitable time for new paradigm shift where design of hardware is completely dictated by the design of software and the design of hardware is simply the matter of selecting proper components available on the market. In this paper we present an example of software and hardware design of ship's communication device using this software driven design strategy. By the end of this paper, it will be shown that such an approach not only decreases the possibility of design errors but it allows rapid prototype design, as well.
