PCILeech FPGA Summary:

PCILeech FPGA contains software and HDL code for FPGA based devices that may be used together with the PCILeech Direct Memory Access (DMA) Attack Toolkit and MemProcFS - The Memory Process File System. FPGA based hardware provides full access to 64-bit memory space and may also send raw PCIe Transaction Layer Packets TLPs - allowing for more specialized research.

Supported Devices:

PCILeech currently supports multiple FPGA based devices with most recent firmware versions - please see the table below:

*) PCILeech FPGA uses PCIe x1 even if more PCIe lanes are available hardware-wise. This is sufficient to deliver neccessary performance.

Select the FPGA setup that best suits your needs from the above list. If performance and value for money is key the Screamer PCIe Squirrel is currently recommended. If performance is key alone ZDMA is a good pick.

Check out the individual FPGA projects in the table above for more information about the purchase, usage, building and flashing of the devices. Each device have different advantages and disadvantages.

A special Thank You 💖 to the project hardware sponsors!

Thank You CaptainDMA, LightingZ and Enigma-X1 for supporting the PCILeech and MemProcFS projects 💖

  • Top row: CaptainDMA 100T and ZDMA.
  • Middle row: CaptainDMA M2, CaptainDMA M2 100T and LeetDMA.
  • Bottom row: NeTV2, SP605 and AC701.

Older Devices:

PCILeech also supports multiple FPGA based devices that may not have the most recent firmware available for download, but will still work with some limitations. If purchasing a new device it's recommended to get a currently supported device rather than a legacy device.
