High-Performance Data Preprocessing Platform with Multi-FPGA PCIe Bus Architecture Based on 5 K7 FPGAs

• Onboard FPGA Real-time Processor: XCKU060-2FFVA1517
• 2 QSFP+ Optical Interfaces, supporting up to 10Gbps/lane
• Onboard DMA Controller for high-speed bidirectional DMA transfers
• Supports x8 PCIe Host Interface, system bandwidth 5GByte/s
• 1 RJ45 Adaptive Gigabit Ethernet Port
• 1 FMC+ Daughter Card Expansion Interface

This high-performance data preprocessing FMC carrier board is based on a PCIe bus architecture. The board features 1 FMC+ (HPC) interface, 1 PCIe x8 host interface, 1 RJ45 Gigabit Ethernet port, and 2 QSFP+ 40G optical fiber interfaces. It utilizes Xilinx's high-performance Kintex UltraScale series FPGA as a real-time processor to enable FMC interface data acquisition, processing, and backplane interface interconnection. The board includes two independent 72-bit DDR4 SDRAM large-capacity caches. By integrating various FMC daughter cards, this board can quickly establish server-based data acquisition, real-time processing, and high-performance storage platforms. It can be widely applied in scenarios such as radar and IF signal acquisition, and video image acquisition.
