摘　　要：为了实现ADIS16355数据采集与导航运算的并行处理，本文设计了基于TMS320C6713的高精度数据采集系统。利用TMS320C6713的多通道缓冲串口（McBSP）对ADIS16355测量结果进行采集，采用增强型直接存储器访问控制器（EDMA）方式和乒乓缓冲技术进行数据传输和存储，减少了外围电路，提高了导航系统的实时性和稳定性。In order to simultaneously complete data collecting and navigation calculating of ADIS16355, a high precision data collecting system based on TMS320C6713 is designed. The ADIS16355 signal is collected by using the McBSP of TMS320C6713 and the data is transferred by the manner of EDMA and registered by the technique of Ping - Pong Buffering. The data acquisition system obviously simplifies peripheral circuit and improves the timeliness and stability of the navigation system.
