摘　　要：为了实现任意波信号发生器的协调工作,提出了发生器控制系统的硬件和软件的设计方案。硬件部分以HMS30C7202微处理器为核心,FLASH和SDRAM作为存储设备,从矩阵键盘接受输入,并在LCD上显示相应内容。软件分为底层驱动程序和上层控制程序两部分设计,系统上电后首先能够设置系统模式和时钟、初始化存储器。进入主流程后上层控制程序不断查询是否有键按下,若有键按下,则执行相应的任务,LCD显示相应内容。In order to realize the harmonious work for Arbitrary Waveform Generator, the design blue print of control system that have hardware and software were put forward. The microprocessor ARMHMS30C7202 is core, FLASH and SDRAM are storage, matrix keyboard is input and it is displayed on the LCD in hardware. There ware two part in software those are rock-bottom driving and topper control programmer, when the current is put on, the pattern and clock are intercalated at once. The bond isn＇t pressed is inspected ceaselessly by the topper control programmer when it has gone to the flow main programmer. If the key has done, the content is displayed on LCD.
