Abstract

Aiming at the increasingly stringent requirements for reliability, intelligence, and high-precision data acquisition in airborne systems, this paper deeply studies the working principles and hardware composition of Fudan Microelectronics' FMQL series chips, and develops an avionics data acquisition system platform based on Fudan Microelectronics' FMQL SoC chip and the Linux system. In the design, the JFMQL100T900-N chip is used as the processor. The PS (Processing System) core processing unit, primarily built around the FPGA, is responsible for controlling and processing signals from external devices, as well as data storage tasks. The PL (Programmable Logic) interface unit mainly handles Ethernet communication. For Ethernet data transmission, AXI DMA (Advanced eXtensible Interface Direct Memory Access) is employed to transfer data. Communication and data exchange between the PS and PL units are facilitated through the AXI general-purpose communication interfaces.
