I. Overview of boards

The high-performance PCIe signal processing board based on V7 chooses the Virtex7 series FPGA XC7VX690T-2FFG1761C of Xilinx Company as the processing chip. The board provides two standard FMC slots, which is suitable for high-performance acquisition, playback and related processing in the fields of electronic countermeasures or radar signals. By connecting different FMC daughter cards, different forms of functional modules of data acquisition, playback and processing can be realized. The schematic diagram of the board is shown in the following figure:

Second, the main functions of the board

1. Main APIs

8-way optical fiber SFP+,1 QSFP+, can support 2.5Gbps10Gbps and other transmission rates.

1 PCIe X4 connector electric port, connector is molex interface, can support optical fiber transmission in use. 1 PCIe X8 standard interface, supporting V2.0 and V3.0 specification, 1 gigabit network.

2. Indication display

Eight LED FPGA working status indicators are yellowish green, one fault red light (pulled to the FPGA), one power supply light yellow (indicating + 12V), and one reset light. Six LED lights are yellowish green for indicating the working status of the optical module.

3. Control button

8 Swtich, 4 push button buttons, and one reset button.

4. Card caching

FPGA plug-in 2 groups of DDR3 SDRAM, each group of capacity 4GB, bit width 64bit, working rate 1333MHz.

5. Extend the interface

The board provides two FMC HPC interfaces, which can be connected to FMC daughter boards, such as AD,DA and optical fiber interface cards.

III. Application of board

Radio, radar, 10 Gigabit accelerated computing, with CPU motherboard can complete the product development.
