基于SOPC的便携式示波器设计

Design of portable oscillograph based on SOPC

随着军队院校教学改革的不断推进,实践教学的地位得到进一步加强,如何设计综合性实践教学案列,培养学生综合运用电子技术知识解决实际问题的能力,成为制约电子技术实践教学效果进一步提升的关键。将部队常用的便携式测试设备中的通用功能＂数据采集与显示＂提炼为实践教学案例,基于SOPC设计便携式示波器,通过多通道模数转换实现数据采集,通过FPGA设计交叉采样同步存储、门限检测等片上逻辑,以NiosII为软核构建片上系统实现波形显示。

Along with advancing of educational reform in military school,status of practical teaching is more important,how to design comprehensive case for practice teaching to develop students＇ ability to analysis and solve practical matters,has been the key to further improve the teaching effect of practical teaching in electronics.Portable test equipment is common in troops,and ＂data sampling and display＂is the general module,which is the basement to design practice teaching case.Portable oscillograph is desighed based on SOPC,data sampling is accomplished in multichannel,synchronizing storage of time-interleaved is designed based on FPGA as well as detection threshold,waveform display is realized by SOPC with the softcore of NiossII.
