机载数据总线ARINC 429在当代的运输机和相当数量的民用客机中有着广泛的应用。目前国内的专用ARINC 429信号处理芯片一般路数有限,要实现多通道的信息处理,就需要多块类似的芯片,从而体积就会变的比较庞大,非常不灵活。,因此利用FPGA和DSP相结合,设计和研制的ARINC 429总线信号处理板,成为目前飞机机载总线接口研究的重点,具有非常重要的现实意义和应用前景。

-The airborne data bus, ARINC 429 has a wide range of modern transport aircraft and a considerable number of civil aircraft applications. Domestic dedicated ARINC 429 signal processing chips are generally large ones limited to multi-channel information processing, you need to block similar chip, so the volume will become relatively large, and very flexible. , So the use of FPGA and DSP combination of design and development of ARINC 429 bus signal processing board, become the focus of the aircraft airborne bus interface has a very important practical significance and application prospects.
