The ARINC664 AFDX Terminal IP Core is a fully compliant FPGA-based IP module designed according to the ARINC664 Part 7 specification. Supporting two configurable ARINC664 ports with data rates of 10/100/1000 Mbps, this IP core enables rapid development of ARINC664 terminal network interface cards. By integrating the complete ARINC664 protocol stack within the IP core, it minimizes CPU workload, ensuring real-time performance, determinism, high reliability, and system stability.

With its compact footprint and low resource consumption, the IP core is ideally suited for embedded systems with stringent requirements for power, size, and reliability. It allows developers to accelerate system design, reduce risk, and shorten time-to-market. The core has already been validated on leading FPGA platforms from AMD (Xilinx) and Intel (Altera), as well as compatible domestic alternatives, making it highly versatile for avionics, automotive, and maritime applications.
