Abstract: The problem of resources and energy is increasingly getting public attention because of the development of science and technology. In this case, people have a higher demand of the portable and power-saving devices. In the postPC era, the embedded-system devices came into being. Since the research of any problem should follow “from the whole to the part, from the simple to the complex, from the shallow to the deep” rule, embedded systems structurethe predominant topicis worthy of exploration before handling its related issues. Despite the past research on the structure by scholars and technologists, this paper demonstrates that the social development and people's learning process should follow “naturalness” and “the theory of process”from the perspective of philosophy.
