The ARINC-429 IP Core is a multi-channel ARINC 429 transmitter and receiver core for serial communication in airborne applications. The IP is developed, validated & licensed by Oxytronic.
This IP Core has been developed according to the RTCA/DO-254 ED-80 guidelines. These guidelines are required by the Airworthiness Certification Authorities (EASA and FAA) for hardware developments that need to be certified for the use in commercial aircraft equipment.
The IP Core incorporates various state-of-the-art CPU interfaces which can easily be connected to your required interface. Each individual channel can be configured according to your specifications.
Each channel contains a specific buffer (FIFO), incorporated in the IP. This allows efficient data transfer between CPU and the IP.
