| Abstract: | Based on the constant requirement of speed and stability for data transmission in measure ment and control system,a high-speed I/O card of multiple digital channels is designed and developed by combining serial communication standard LVDS and serial communication specification SPI.The designed card is implemented by the ALTERA FPGA chip EP3C16Q240C8.The programming and simulation of this card is developed in QuartusII.The proposed card has being applied in monitoring and control system successfully.Results shows that the card is reliable and stable in operation to meet the real needs. |
