System specification of wireless multimedia engines: a data fusion approach

This paper presents a pragmatic approach to the specification of wireless multimedia terminals, covering the requirement capture, functional specification, and system architecture selection phases of wireless engines. The emphasis is on the definition of the system architecture for the wireless engine platform. The accurate technology evolution estimates and technology planning is regarded as the main driving force in the long-term, continuous technology development. Well-defined technology roadmaps shorten the time used for requirement capture process. An “application based” approach concentrating on the most demanding, new terminal sub-systems is suggested for functional specification of open, multi-system terminal platforms. Also, an interactive and semi-automatic “data fusion” process is proposed for the engine architecture selection. In the data fusion process, advanced EDA tools are seen as design assistants, serving the decision making towards a feasible system architecture, but not dominating or restricting the specification and design of multimedia driven engine platforms
