摘要
针对软件GPS接收机的实时数据采集需求,提出一种基于TMS320C6416McBSP、EDMA、中断和外部扩展SDRAM的GPS实时数据采集方案;重点阐述射频前端NJ1006AK、TMS320C6416构成的硬件接收电路,以及McBSP、SDRAM、EDMA乒乓缓存的采集配置过程。该方案不仅满足了GPS软件接收机信号采集严苛的实时性要求,而且增强了处理器实时处理能力。
A solution is proposed for reai-time data acquisition of GPS signai based on TMS320C6416 McBSP, EDMA, interrupt and SDRAM. The hardware receiver circuit based on NJIOO6AK and TMS320C6416, and the configurations of McBSP, SDRAM and EDMA ping-pang huller operation are described. Strict real time requirement of the software defined GPS receiver is satisfied, and the real time processing capacity of the processer is enhanced.
