| Abstract: | This paper is about the concept, operational theory and principal structure of Boundary Scan. The JTAG controller based on boundary scan is designed and implemented. According to the functional implementation of the JTAG controller based on boundary scan, a certain kind of chip and the corresponding instructions are taken as an example. The research result of this paper provides foundation to the future embedded boundary-scan test research work. |
