基于DSP的高速数据采集与存储系统设计

Design of High-Speed Data Acquisition and Memory System Based on DSP

提出一种基于DSP的高速数据采集与存储系统的设计方法。以TMS320F28335为核心控制器,通过内部ADC完成模拟信号的采集转换,使用DMA模块将转换后的数据高速传送到DSP外扩的SRAM中。以DMA方式传送数据,可降低CPU资源消耗,提高传送效率。经测试该方法能够有效可靠地进行数据采集与存储,为后续的数据处理工作奠定基础。

Designs a high-speed data acquisition and memory system based on DSP. This system adopts TMS320F28335 as the core controller chip, the date was acquired by ADC of DSP, and the converted date is transmitted to external SRAM by high-speed DMA. This system uses DMA to transmit date, which can reduce CPU resource consumption and improve the transmission efficiency of data. Experiments show that this system is stable and reliable to accomplish data acquisition and memory, and can be applied to data processing later.
