Aviation data controller based on FPGA

Abstract

The invention discloses an aviation data controller based on an FPGA. Real-time sampling, conversion and management of aviation communication protocol ARINC825 and TTP data can be efficiently completed. The controller is composed of an ARM module, an FPGA protocol processing core module, a CMOS level and ARINC825 level conversion module and a CMOS level and TTP level conversion module. The FPGA protocol processing core module performs parallel processing and accurate time sequence control on protocol data, so that high-speed analysis and switching of two aviation bus protocols are realized, and the stability and response speed of data transmission are remarkably improved. Through unified acquisition and scheduling of different protocol data, the data interface design of an avionics system is simplified, the integration level and reliability of the system are improved, and the system is especially suitable for multi-protocol cooperative communication control in a complex aviation application scene.
