ARINC 429 Receiver

ARINC 429 Receiver

The ARINC 429 RX is a soft IP for a single receiver for serial communication in airborne applications. It has been developed in compliance with the requirements and objectives of the DO-254 DAL A. As a COTS IP, it can be instantiated as many times as required within a SoC to have multiple ARINC 429 receivers. This IP has the following technical characteristics:

  • Automatic detection of the ARINC429 bus bit rate: high speed or low speed.
  • Decoding of the serially received data through data_high and data_low inputs
  • Received frames format check (Bit rate, Frame width, Inter-frame gap) and parity errors checks
  • Errors are highlighted to the user through external status/flags outputs and erroneous frames are discarded
  • Error free frames are stored in a FIFO within the ARINC429-RX IP
    • FIFO size is configurable by the user (from 2 to 512 words)
  • User performs read accesses to the FIFO through 32-bit interface to retrieve the received frames
