摘要
针对高校实验考核过程中存在的设备成本高与监考工作量大等难题,采用Raspberry Pi(树莓派)和FPGA相结合,通过PCI-e2.0协议实现异构高速双向通信,多功能仪器设备一体化设计,同时采用DMA传输模式,减少CPU资源占用,完成数据高速采集,通过Linux与数据库实现实验考核在线系统设计,大大提高了高校教育信息化在高校实验考核的信息化程度。
In view of high equipment cost and invigilation workload in the process of college experiment assessment,the paper uses the combination of Raspberry Pi and FPGA to realize heterogeneous high-speed two-way communication through the PCI-e2.0 protocol,multi-functional instrument integration design,adopts DMA transmission mode,reduces CPU resource usage,and completes data acquisition;by this way an online system design of experimental assessment is realized through Linux and database.It has greatly improved the degree of college education informatization in college experimental assessment.
