With the advent of VLSI system level integration and system-on-chip, the center of gravity of the computer industry is now moving from personal c- puting into embedded computing. Embedded software and systems are incre- ingly becoming a key technological component of all kinds of complex technical systems, ranging from vehicles, telephones, aircraft, toys, security systems, to medical diagnostics, weapons, pacemakers, climate control systems, etc. The ICESS 2005 conference provided a premier international forum for - searchers, developers and providers from academia and industry to address all resulting profound challenges; to present and discuss their new ideas, - search results, applications and experience; to improve international com- nication and cooperation; and to promote embedded software and system - dustrialization and wide applications on all aspects of embedded software and systems.
