Device

Virtex-7 XC7VX690T-2FFG1761C FPGA

Configuration

FPGA configuration is determined by DIP switch SW11.

Config mode 1 2 3 4 5
Master BPI Note 4 Note 4 0 1 0
JTAG (independent) X X 1 0 1

Notes:

  1. X = don’t care
  2. 0 = OFF position
  3. 1 = ON position
  4. Switches 1 and 2 are A25 and A24 respectively and determine which of 4 bitstreams is booted from the Linear BPI flash

Comparison of 7 Series FPGA boards for PCIe

Comparison of 7 Series FPGA boards for PCIe
One of my most common customer requests is to speed up execution of a software application using FPGA hardware acceleration. If the application runs on a PC or server, you can achieve impressive performance gains by using off-the-shelf FPGA development boards for PCI Express. Here is a comparison of the available 7 Series FPGA boards for PCI Express applications: AC701 Artix-7 KC705 Kintex-7 VC707 Virtex-7 VC709 Virtex-7 $1295 $1695 $3495 $4995 XC7A200T-2FBG676C XC7K325T-2FFG900C XC7VX485T-2FFG1761 XC7VX690T-2FFG1761C 4-lane Gen2 PCIe 8-lane Gen2 PCIe 8-lane Gen2 PCIe 8-lane Gen3 PCIe 1GB DDR3 SODIMM 1GB DDR3 SODIMM 1GB DDR3 SODIMM 4GB DDR3 SODIMM x2 8Kb EEPROM 8Kb EEPROM 8Kb EEPROM 1KB EEPROM No BPI Flash 128MB BPI Flash 128MB BPI Flash 32MB BPI Flash 32MB Quad SPI 16MB Quad SPI 16MB Quad SPI No Quad SPI Flash SD Card slot SD Card slot SD Card slot No SD No LPC FMC 1x LPC FMC No LPC FMC No LPC FMC 1x HPC FMC (*) 1x HPC FMC (*) 2 x HPC FMC 1x HPC FMC (*) 1x SFP 1x SFP+ 1x SFP+ 4x SFP/SFP+ 1GB Ethernet 1GB Ethernet 1Gb Ethernet No Ethernet No USB No USB No USB No USB UART over USB UART over USB UART over USB UART over USB HDMI out HDMI out HDMI out No Video XADC header XADC header AMS port No Analog (*) Note: These HPC FMC connectors are only partially populated which means that they wont be able to support all standard FMCs.
