针对研究生课程“实时数字信号处理”教学中存在的难题，本文讨论了增强型直接内存访问（EDMA）传输机制对于系统实时性的影响，提出了一种基于乒乓双缓存的数据流结构。为方便开展课堂教学，本文以 DSK6416硬件实验板为平台，提出了一种系统实时性定量测量方法，通过测量结果给出了满足实时性的最佳参数组合，有效弥补了理论教学在阐述 EDMA 机制流程方面的不足。

In order to solve the teaching puzzle in the Real-time Digital Signal Processing course,the EDMA mech-anism and effect on real-time system is investigated. A double buffering framework based on Ping-Pong buffer and EDMA is proposed;Consider about the convenience of teaching and learning,the measurement of system real time based on DSK6416 hardware platform is also discussed. It shows that optimal combination of parameters can be ob-tained from measure results. This method is a significant supplementary of theoretical teaching about EDMA mecha-nism.
