摘要:

设计了一种基于FPGA的多仪表合一的实现方案。系统应用32位Nios软核,以SOPC配置灵活的优势在DE2板上定制了硬件系统,并在Nios IDE环境下编程实现了数字示波器、函数信号发生器的功能。该系统避免了控制单元与时序单元的分立设计,具有较好的可移植性。测试结果表明,该设计能较好地实现示波器和函数信号发生器并行工作。

关键词: FPGA, 仪表合一, 数字示波器, 函数信号发生器

Abstract:

The implementation scheme for the all-in-one instrument based on FPGA is proposed.It applies the 32bits NIOS processor and customizes the hardware system on DE2 Development based on the flexible allocation of SOPC.The function of digital oscilloscopes and function signal generator is realized through programming in the NIOS IDE environment.This system makes the control unit and timing unit designed on one chip and therefore achieves good portability.The experimental results show that the oscilloscopes and generator can work in parallel.

Key words: FPGA,the union of one more instruments,digital oscilloscopes,function signal generator
