摘要
基于DSP技术设计出一种工作状态可控的信号采集系统。系统采用DSP+CPLD结构,DSP对数据进行处理,并对外设进行控制,CPLD对DSP及外设芯片间的控制信号进行协调。AD模块对模拟信号进行采样,Flash保存DSP的运行程序和数据,从而实现系统的脱机运行。该设备运行稳定可靠,工作方式灵活可控,具有巨大的市场潜能。
The controllable signal acquisition system is based on DSP. This system is able to achieve high-speed analog signal acquisition. It adopts the DSP ＋ CPLD structure. The process and calculation of data is realized by DSP. CPLD is in charge of the AD and other equipments. The external Flash saves the code and data. So the system can run without the assistance of computer. This system runs stably and accurately in the test. The technology and methods adopted in the system are worthy of using abroad.
