High-performance digital processing module (2-FPGA Xilinx Kintex 7, PCIe x4)
The high-performance digital processing module is a digital hardware platform, made in the PCI Express form factor and includes in structure:
- Two FPGAs Xilinx Kintex 7 XC7K325T;
- Three connectors for SFP and SFP+ modules;
- SMA connector for receiving and transmitting high-speed serial digital signal;
- Module slot for DDR3 memory in the SO-DIMM form factor;
- High-speed SSRAM memory QDR-II + type of 18 Mbps;
- Five general purpose connectors for the expansion modules (to increase the amount of memory, input digitized analog signals, installation of digital signal processors, ASICs and data processing, etc.).
The image of the module is given in figure 1, the block diagram is submitted in figure 2.

For data input and output the module has three SFP+ connectors, providing up to 10 Gbit/s bandwidth each (including interface specifications according to Ethernet), as well as two pairs of SMA connectors for connection via high-speed serial differential interfaces. Maximum speed data input and output via SMA connectors is also 10 Gbit/s.
The module supports PCI Express rev. 1 interface with x4 bus width and with 10 Gbit/s maximum bandwidth that allows to use it in conjunction with a personal computer and to make prototyping of embedded systems.
The possibility of data storage with fast access time to the memory chip QDR-II+ (maximum clock frequency of the interface is 400 MHz), or with a largHigh-performance digital processing module (2-FPGA Xilinx Kintex 7, PCIe x4)e data storage (up to 8 GB with a clock frequency up to 1066 MHz) in the DDR3 SO-DIMM module is provided.
Large set of connectors for expansion modules allows flexible configuration of peripheral devices of each FPGA. Input-output interfaces with supply voltages 3.3 V (297 pins in one FPGA and 100 on another) and 1.8 V (150 pins), including differential are provided. Additionally, high-speed signals bidirectional serial interfaces are brought to these connectors with a total bandwidth of up to 70 Gbit/s.
FPGA Kintex 7 XC7K325T connected by a line of high-speed communication between the FPGA total bandwidth of up to 80 Gbit/s. This computing diversity allows the effective sharing of computing power of both chips.
