Signal processing platform based on CPCI architecture and FPGA

The invention discloses a signal processing platform based on a CPCI (compact peripheral component interconnect) architecture and an FPGA (field programmable gate array), which comprises a board card, three FPGA chips and a CPCI connector are carried on the board card, the CPCI connector comprises a J1 interface, a J2 interface and a J3 interface, the three FPGA chips are respectively an FPGA (field programmable gate array) A1, an FPGA A2 and an FPGA A3, the FPGA A1 is connected with the J3 interface through a PCIEx4 bus, the FPGA A2 is connected with the J2 interface through the PCIEx4 bus, the FPGA A3 is connected with the J1 interface through the PCIEx4 bus, and the J1 interface is connected with the J2 interface through the PCIEx4 bus. And every two FPGAs are connected through a group of 4XAURORA and 12 pairs of LVDS (Low Voltage Differential Signaling). The CPCI signal processing platform is higher in universality, richer in external interface and richer in extensible function, can meet various project r
