Characteristics of embedded systems are listed, with a stress on their dedication, the non-separability of their hardware and software, and their being constrained to respond in real time. The design process of embedded systems is described. The process cannot be a process of hardware design alone or of software design alone, but must be one of concurrent co-design. The gap existing between critical-systems engineering and best-effort engineering is explained and its effect on the design of embedded systems is pointed out. The history of progress of semiconductor integrated circuits technology is outlined, and the goal of this progress is identified as the placement of a full system on a single chip. There is a paradigm shift from the design of application-specific integrated circuits to platform-based design. This latter type of design was adopted for integrated circuits after it had achieved dramatic successes in many other engineering disciplines. The vulnerabilities of embedded systems are listed, and their quantitative study via fault trees is briefly explained. Methods of evaluating and upgrading the reliability of embedded systems are also pointed out. Finally, the paper proposes the generalization of the reliability algorithms of partially redundant systems by relaxing the assumption of statistically-independent components, thereby allowing these algorithms to model the reliability of embedded systems. Another proposal of future work asks for the exploration of potential applications of reverse engineering in embedded systems.  Conference Name : Second Conference of the Association of Egyptian Engineers in Riyadh  Publishing Year : 1431 AH 2010 AD  Number Of Pages : 21  Article Type : Article  Conference Place : Riyadh, Kingdom of Saudi Arabia  Organizing Body : The Association of Egyptian Engineers in Riyadh  Added Date : Saturday, June 4, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email محمود علي رشدي Rushdi, Mahmoud Ali Investigator Master mahmoud.rushdi@gmail.com علي محمد رشدي Rushdi, Ali Muhammad Researcher Doctorate arushdi@kau.edu.sa Files File Name Type Description  29836.pdf pdf النظم المطمورة: خصائصها وتصميمها ومعوليتها Back To Researches Page
