Abstract: DSP(Digital Signal Processor) technology is a comprehensive course which involves engineering technology and practice.Hence,helping the students to develop engineering utility capability stands the main position in DSP experiment course.The system components and the main features of TMS320VC5502 experimental platform were introduced,and then some useful exploration and practice based on this platform,including DSP experiment teaching,open experiment and subject competition,were described in detail.Furthermore,some specific applications in DSP experiment teaching were illustrated.It shows that the new reform is useful to further stimulate students’ learning initiativity and creativity,so their comprehensive knowledge utilization ability is enhanced simultaneously.
