The PCIe with FMC Hardware Platform category refers to FPGA or SoC-based carrier boards designed as standard PCI Express cards while featuring one or more FMC (VITA 57.1) or FMC+ (VITA 57.4) connectors.
Instead of being stuck with fixed on-board ports, these boards act as customizable processing engines. The onboard FPGA links high-speed external I/O (via the FMC card) directly to a host PC or server CPU (via the PCIe bus).
