高速数据采集技术──FIFO和双DMA通道在高速数据采集中，无间隔大数据量连续采集和中断引起的丢数是一个难题，其原因是每页DMA（64K）的容量限制，页与页之间切换，内存与硬盘之间的数据传输都需要时间，以及中断使采集动作暂停的时间。吉时利（KEITHLEY）仪器公司的高速多通
High-Speed Data Acquisition ──FIFO and Dual DMA Channels In high-speed data acquisition, the continuous collection and interruption of large amounts of data without gaps is a challenge due to the capacity limitation of pages per page (64K), pages and pages Switch between the memory and hard disk data transfer takes time, as well as interrupt the acquisition action suspended time.
