| Abstract: | This paper proposes a design scheme of DMA mode high - speed real - time data acquisition system based on FPGA. Bottom layer microcontroller provides precise data sampling timing sequence to ensure ADC sampling throughout.Data sampling mechanism under DMA mode supports PCI interface protocol,which ensures systematic high real-time performance.The scheme has excellent portability,can be applied in the data acquisition system which requires high sampling rate,large amount of data and high real-time performance. |
