Design And Development Of Arinc 429 Protocol

ARINC is the major company that develops and operates systems and services to ensure the efficiency, operation and performance of aviation and travel industries. ARINC 429 specification defines how the avionics equipment and systems should communicate with each other. It employs a unidirectional data bus standard known as Mark 33 Digital Information Transfer Systems. ARINC 429 bus operates at 12.5 or 100 kilobits per second. The top level architecture of the ARINC 429 protocol has 4 modules ARINC 429 transmitter, ARINC 429 receiver, Transmit and Receive 512*32-bit FIFO to store and fetch the data and ARINC 429 clock generation. In this proposed work ARINC 429 protocol is designed and developed using Hardware Descriptive Language (HDL). The continuous data stream is stored in a 512*32-bit FIFO. The encoder module at ARINC 429 transmitter converts a continuous data stream into Bipolar Return to Zero format. This encoded data is decoded at the receiver. The decoded data is stored in the ARINC 429 Receive FIFO. The design and development is done using Xilinx software. Keywords— ARINC 429, DITS, BPRZ encoding, FIFO, VHDL
