基于FPGA的高速数据处理系统设计

针对光纤微扰动传感器的高速数据处理问题,设计一种以XC4VSX25为核心,具有数据采集功能、存储功能、LCD显示功能和USB通信功能的系统。利用XC4VSX25带有的XtremeDSPTM IP核,通过并行运算解决高速实时数据处理问题,并且通过Verilog HDL语言设计串行结构和并行结构,并在ModelSim中对两种结构进行仿真比较。结果表明,本系统中并型结构的计算速度是正比于并行度的,可以提高系统处理速度。

Design of high speed signal process system based on FPGA

Aiming at high speed data processing of fiber-optic vibration sensor,a system was designed based on the core controller XC4VSX25 and combined with data acquisition,storage,LCD display and USB communication function.Using XtremeDSPTM IP core of XC4VSX25,real-time high speed data processing was implemented by parallel process of FPGA.The serial structure and parallel structure were implemented with Verilog HDL,and then simulated on ModelSim.It turns out that the computation speed of parallel structure is direct ratio to the concurrency degree,and the parallel structure can improve the process speed.
