Title The design of multi-channel fiber data acquisition
Abstract card with PCIe bus
In conventional digital array and active phased array radar system, high speed data transmission of multi-channel high-speed signal acquisition and DBF adaptive processing system, and signal processing systems are increasingly using multi-channel fiber data transmission technology. In this paper, the multi-channel fiber optic data acquisition card, based on the Xilinx company Kintex-7 series FPGA, using the PCIe bus, optical fiber and DDR3 data storage technologies etc., is designed to achieve higher performance to meet the general requirements.
In this paper,design core of the multi-channel fiber data acquisition card is PCIe protocol and Aurora protocol, specific research work is as follows:
1、During the design of the entire multi-channel data acquisition card, study the FPGA design flow, PCIe interface protocol, optical fiber transmission protocol and DDR3 cache technology.
2、After analyzing the design requirements of the system, study the design of each sub-module hardware, and describes the specific implementation methods.
3、Using FPGA design to implement the logic design of each sub-module, such as PCIe interface logic, design DDR3 cache logic, fiber optic transmission protocol, as well as top-level logic design.
4、Do some functional simulation for each sub-modules and the entire system, and test some important performance indicator of the system.
