Document Table of Contents Programming Multiple FPGA Devices

If you install multiple FPGA devices in your system, you can direct the host runtime to program a specific FPGA device by modifying your host code.

Linking your host application to FCD allows you to target multiple FPGA devices from different Custom Platforms. However, this feature has limited support for Custom Platforms that are compatible with SDK versions prior to 16.1.

You can present up to 32 FPGA devices to your system in the following manner:

  • Multiple FPGA accelerator boards, each consisting of a single FPGA.
  • Multiple FPGAs on a single accelerator board that connects to the host system via a PCIe® switch.
  • Combinations of the above.

The host runtime can load kernels onto each and every one of the FPGA devices. The FPGA devices can then operate in a parallel fashion.
