摘　　要：在兼容维修早期生产的一款基于PC/104总线的近红外光谱仪,在设计新的工控板时,增加了PCI Express总线转PC/104总线的设计。重点介绍了架构设计、PEX8311桥接芯片的直从工作模式和FPGA的控制时序,当PEX8311本地时钟频率为16.5 MHz时,测试的实际传输速率达到6.5 MB/s,能够满足仪器的需求。In the early production of a compatible service-based PC/104 bus near-infrared spectrometer, in the design of new industrial control board, increasing the PCI Express bus transfer PC/104 bus design. Focuses on the architectural design, PEX8311 bridge chip straight from work mode and FPGA to control the timing, when PEX8311 local clock frequency is 16.5 MHz, the actual transfer rate test reached 6.5 MB/s, to meet the needs of the instrument.
