摘要
结合运用NIOSⅡ嵌入式处理器的SOPC技术,选用CycloneⅡ系列的EP2C35F672C6N作为目标芯片,对函数发生器进行设计,完成了SOPC片上系统以及片外处理电路的构建,用VHDL设计了DDS模块,用C语言程序进行波形参数的读取及显示,用QuartusⅡ设计软件,实现函数信号发生器的功能。不仅可以产生用户通常需要的波形信号,而且波形的频率和幅度在范围内可调,用户还可自行通过对自定义组件的添加和系统进程的添加来实现系统功能的扩展。更好地实现了设计的数字化、集成化、微型化、智能化。
Combined with NIOS II embedded processor SOPC technology, using Cyclone II series EP2C35F672C6N as the target chip, design the function generator.Systemon chip and signal process circuit peripheral SOPC construction have been completed during this experiment.DDS module is designed with VHDL,the waveform parameters has been read and displayed with C language.The function of signal generator is attained using QuartuslIsoftware.not only produce the useful waveform by users often need,but also the frequency and amplitude ofwaveform in the range of adjustable, users can also automatically through the custom component is added and the system process to add to realization of system function extension. In order to realize the digital, integration, miniaturization, intelligence.
