Embodiment
[0041] as attached figure 1 As shown, this embodiment provides a high-speed data selection system based on FPGA, the structure of which includes a high-speed data selection board, the high-speed data selection board includes an FPGA module, peripheral electronic device equipment and a PCB board, and the peripheral electronic device equipment includes SFP Optical module, EEPROM memory and RS232 interface. The SFP optical module is used to convert the optical signal input by the optical fiber into an electrical signal and input it to the FPGA module; the EEPROM memory is used for pre-stored data selection information; the FPGA module is used to receive the SFP optical module. After inputting the data, read the data selection information pre-stored in the EEPROM memory, and perform data decoding and selection processing; the RS232 interface is used to output the FPGA module selection data result to the PC terminal.
[0042] The peripheral electronic devices of the high-speed data...
Embodiment 2
[0059] as attached figure 1 As shown, this embodiment provides a high-speed data selection method based on FPGA, and the method is as follows:
[0060] S1. The user inserts the input optical fiber interface into the high-speed data selection board, and uses the RS232-CH340 data cable to connect the RS232 interface to the PC;
[0061] S2. Turn on the power switch of the high-speed data selection board, install the Vivado software in the computer system to be tested, and program the bit file of the FPGA data selection project to the board FPGA module through the JTAG data line;
[0062] S3. Open the running software of the upper computer installed on the PC, and view the selection result of the high-speed data selection on the optical fiber input signal through the visual interface. The user can save the data as needed or perform the next application as needed.
[0063] as attached figure 2 As shown, in step S3 in this embodiment, the user saves the data as needed or performs...
