Abstract


Combining with the avionics data processing system at home and abroad, the development situation of design of a set of data acquisition, processing, control and transmission in an avionics processing system. This article first a deep research on the principle of adaptive filter, this paper analyzes the LMS algorithm performance, emphatically from the factors of influence algorithm performance, through the analysis of the simulation, the improved algorithm, improve the algorithm performance, the simulation results are analyzed, and applied to the design of the system; Secondly introduces the ARINC - 429 air bus and the RS - 422 serial bus information standards and transmission format. On this basis, based on the FPGA design to solve the avionics system data acquisition, filtering processing, control transmission and complicated nonlinear operation integration implementation scheme. Choose XILINX company FPGA, realized the avionics data acquisition, transmission and control, integrated the ARINC - 429 and RS - 422 two kinds of communication interface, realize the bus redundancy, and realized data filtering and the corresponding algorithm processing. Finally, in the laboratory environment, for each module separately carried on the hardware and software testing.
