The paper further realizes a hardware accelerate boundary-scan controller to improve the performance of the remote experiment system. The controller can realize the process of "configuration" and "verify"automatically without the control of CPU. The controllers operation in the remote experiment system can reach the expected goal. By performance analysis, we conclude that hardware accelerate boundary-scan controller is significant faster than that realized with software.
