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.
