Research on Embryonic System and Its Key Technologies

Embryonic system is a kind of bio-inspired robust fault-tolerant hardware, which can acquire self-diagnosing and self-repairing capabilities. A brief introduction is given on the concept, merit, applications and implementation methods of embryonic system. A detailed review is given on the key technologies, e. g. framework, design methods, mechanism of fault tolerance, etc. of embryonic system. A simple application of an octal counter is given to demonstrate the design method of embryonic system. Now there are many difficulties in the research of embryonic system, e. g. simple fault-tolerant mechanisms, cell-circuit structure and design methods. And some ways and means, such as error detection based on immune mechanism, hierarchical fault-tolerance and IP core based circuit designing, are given. In addition, exploring new fault-tolerant mechanisms and various bio-inspired circuit system structures as well as developing commercial and special embryonic system chips are also the key to the study.
