| Abstract: | In order to collect real-time flight parameters accurately,the design of a multi-channel data acquisition system was proposed using FPGA as the core.The system hardware design was described.Pipeline sampling and data communication between FPGA and DSP were both realized by Finite State Machine described in VerilogHDL,and the design modules were simulated by Modelsim.Experiment proved that this design simplifies the complexity of the hardware circuit and makes the data acquisition system possess a flexible a... |
