摘要
针对载机任务单元多通道数据采集记录的需求,设计了一种基于高速浮点运算数字信号处理器(DSP)TMS320C6713的机载数据采集记录系统。利用TMS320C6713处理器芯片集成的增强型直接存储器存取(EDMA)和同步多通道缓冲串行口(M cBSP)模块实现对存储芯片的直接连接和数据操作,简化了硬件接口设计,避免了总线冲突,提高了处理器的工作效率。系统在某型数字化对抗训练系统中的实际应用表明该设计实用可行,并在实时数据采集记录应用中具有较好的通用性和扩展性。
Aiming the demand of aviation task units multi-channel data acquisition and record,this paper designs aerial data acquisition and record system based on high-speed data signal processing（DSP） TMS320C6713.The system realizes the direct connection and data operation to memory chip through McBSP and EDMA modules integrated in TMS320C6713,which simplifies hardware interface design,avoids bus corruption and improves CPU work efficiency.Its successful implementation in one digital counterwork training system proves that the design is feasible and practical.The design is a universal and expandable example which applies to the realm of real-time data acquisition and record.
