介绍了基于现场可编程门阵列(FPGA)技术实现波形显示的两种方法,同时针对波形显示中出现的不稳定性提出了一种稳定显示波形的策略。首先利用高速A/D转换器将采集的波形信号进行波形稳定控制,然后存进FPGA片内的RAM中,最后以VGA方式实时地显示出来。给出了两种方法的VGA波形显示图,并对比分析了两种方法的特点。

Two methods of realizing waveform display based on FPGA (Field Programmable Gate Array) technology were introduced, and meantime proposed a strategy of stable showing waveform aiming at appeared instability of waveform display. Using high-speed A/D, the acquisition signals were firstly stably controlled for waveform stability, and then stored them into the FPGA on-chip RAM, finally displayed in real-time VGA (Video Graphics Array) mode. Also gave two VGA method waveform diagrams and analysized in contrast the characteristics of the two methods.
