基于FPGA的实时数据采集系统设计
Design of Real-time Data Acquisition System Based on Field Programmable Gate Array
摘要
Abstract
Real-time measurement and control under mega data condition and with long-term stability is a hard task for a computer with Windows operating system. The current electronic control part in the reflectance difference spectrometer meets the same problem. To improve its real-time capability, a design based on Field Programmable Gate Array(FPGA) development board is proposed. The technique of NiosII softcore from Altera is used to build a control platform for performing high speed USB communications among FPGA board, computer, and detector. Functions for synchronizing the working point between detector and encoder and reading data from encoder are realized in a Verilog Hardware Description Language(VHDL) file, which is integrated in the softcore platform as a module. Experimental results show that the new controller meets the requirements of real-time capability and multi-task control. A frame with softcore processors and self-programmed functional modules is a reasonable solution for on-board control in scientific instruments.关键词
