| 摘 要： | TI公司C6x系列数字信号处理器（DSP）所具有的增强型直接存储器访问方式（EDMA）,相比于DMA配置更加灵活,通道更加丰富。分析了增强型直接存储器访问EDMA2和EDMA3两种传输机制,验证了EDMA3在传输性能上的优势,并将EDMA3方式应用于航迹片段规划系统对大量数据的传输和处理。通过控制EDMA3不仅提高了数据传输速率,而且充分发挥了DSP中央处理单元的快速计算能力。

| Abstract: | EDMA on the C64x DSP is programmed more flexibly and contains more channels compared with DMA.The transfer principle of EDMA is analyzed and the advantage on transfer performance of EDMA3 is testified by experiments.EDMA3 is applied to transfer and process of massive data in route segment planning system.The results show that using EDMA3 not only improves the efficiency of data transfer but also exerts the high speed performance of DSP completely. |
