A Formal Specification of Reusable Framework of Embedded System

Abstract

Because embedded system is combined system of hardware and software, we should design by considering elements such as real-time, reactive, small size, low weight, safe, reliable, harsh environment, low cost, and so on. However, those are poorly reflected on current embedded system development. Especially, there is few existed framework-based embedded system development. As a result, there are many internal codes which is not related with system operation in currently developed embedded system, and reusability or variability is not considered into embedded system development. Therefore we propose a formal specification technique using Z language to guarantee completeness or consistency of design of reusability framework proposed for improving reusability of embedded system. Also we assure correctness of framework design by checking Z model through Z-Eves Tool.
