Avionics full-duplex switched Ethernet (AFDX) technology enables deterministic Ethernet networking for avionics and aircraft systems. The 100 Mbit/s AFDX LFT End System card supports rate-constrained traffic shaping to ensure bounded latency and jitter for deterministic Ethernet networking, as described in ARINC standards. The card can be used for production system integration and provides high-integrity redundancy management as well as an IP/UDP profiled communication layer fully implemented in hardware.

ZYNQ is an ARM SoC based FPGA from Xilinx. It includes Dual-core ARM A9 CPU, high-speed transceiver for PCIe support and 2x Tri-mode Gigabit Ethernet make it suitable candidate for AFDX implementation.

The host communicates with AFDX Card via a dedicated driver. The driver uses DMA for fast data transfers between the host and the AFDX Card. The on-board ARM processor in ZYNQ runs the AFDX protocol stack offloading the host-processors executing user applications. For efficient protocol processing, all IP/UDP are implemented in programmable logic fabric of ZYNQ. The receive and transmit buffers may be configured to operate as either sampling ports or queuing ports. A sampling port utilizes a single message buffer while a queuing port contains storage for multiple messages in a FIFO configuration.
