摘要
基于FPGA的数字存储示波器,以可编程逻辑器件ACEX1K30TC144-3和89c51单片机为核心,由通道输入调整、数据采集、数据处理、波形显示和操作面板等功能模块组成。系统中的数据采集及数据处理模块,采用了FPGA内制的RAMIP核,使系统的工作频率基本不受外围器件影响,经maxplusII延时分析,其内核频率可以达到40MHz以上,这对于数据处理速度和实时性要求比较高的应用领域具有重要的意义。
The digital storage oscilloscope based on FPGA, with PLC ACEX1K30TC144-3 and 89c51 microprocessor as the core, consists of functional modules, such as input channel adjustment, data acquisition,data processing, waveform display and operation panel. In this system, the data acquisition and data processing modules which adopt RAMIP core build-in FPGA protect the service frequency of the system from peripheral device.The kernel frequency may be over 40MHZ by maxplus II time-delay analyzing,and it is significant for the influence caused by the speed of data processing and the application area which requires higher practicability.
