FPGA Implementation of High-Speed Avionics Bus Protocol AS5643

The high-deterministic and reliable AS5643 protocol is introduced and analyzed.In order to release the processors from complex protocol,the implementation of AS5643 protocol based on FPGA(Field Programmable Gate Array) is proposed,and the system design and VHDL(Very-High-Speed Integrated Circuit Hardware Description Language) implementation of the protocol module are explained in detail.Experiments show that the realized module based on FPGA is in accordance with the AS5643 protocol standard.This module can be used in integrated avionic systems which require high-performance serial bus.
