摘要
以Altera公司的DE2实验板作为硬件平台,采用SOPC嵌入式系统设计技术,基于QuartusⅡ软件,设计并开发了一个能够产生正弦波、方波、三角波,且频率、幅值在一定范围内可调的波形发生器实验。完成了SOPC片上系统及片外信号处理电路的构建,用VerilogHDL设计了DDS模块,用C语言程序进行波形参数的读取及显示。该实验涉及硬件描述语言逻辑电路设计、微机系统构成、硬件电路设计及C语言编程等知识的运用,知识综合性强,设计技术新、难度大,对提高学生的知识综合运用能力、动手能力和创新能力具有重要的促进作用。
With the hardware platform of DE2 experimental board of Altera company,using the SOPC technology based on embedded system design and Quartus Ⅱ software,a waveform generator which can produce a sinusoidal,triangle,square waves and frequency,amplitude adjustable within a certain range,has been designed and developed. System on chip and signal process circuit peripheral SOPC construction have been completed during this experiment,DDS module is designed with Verilog HDL,the waveform parameters has been read and displayed with C language. Hardware description language logic circuit design,computer system,the hardware circuit design and the C programming language knowledge are involved in this experiment. Important action are produced for the improving the students＇ comprehensive ability and knowledge of practical ability and creative ability because of the comprehensive knowledge,new technology design,design difficulty of the experiment.
