Based on the Construction of National Computer Experiment Teaching Demonstration Center, this paper focused on some problems existing in the experiment teaching for computer hardware series, built experiment teaching architecture for computer hardware series of "Two levels, Three Steps and One Technology Roadmap" with engineering characteristics, updated the idea of experiment teaching and improved experiment teaching method and means, established a wide range of experiment teaching system. Practice shows that the experiment teaching system and mechanism could greatly improve the students’ practice and innovation abilities.
