环境实时监测中基于PCI总线的数据采集系统的应用
The Application of Data Acquisition System Based on PCI Bus in Real Time Inspecting System of Surroundings
【摘要】 设计一个基于PCI总线进行高速数据采集的环境实时监测系统,该系统利用S5933的FIFO实现高速数据采集,最大限度利用PCI总线的带宽和其高速传输能力.采集的数据以DMA方式直接存入指定的主机存储区,在这过程中不需要CPU干预,提高了CPU的效率.
【Abstract】 A real time inspecting system of surroundings based on PCI bus is given in this article. It can gather data with high speed by using the FIFO of S5933.The bandwith and high transfer speed of PCI bus are maximum used.The data gathered is stored to the appointed depository by DMA mode without the intervention of CPU.So the efficiency of CPU is improved.
