【摘要】 本文介绍了以TI公司新一代高效率、低功耗数字信号处理器TMS320VC5510为核心实现的便携式测试设备的软硬件设计，以等效采样技术实现采样宽频谱周期信号对采样定理的要求，在CPLD内集成完整的LCD控制核代码，并以CPLD作为LCD控制器取代专用控制器，以STN彩色LCD作为终端显示设备，该方案具有功耗低、集成度高、良好的人机接口等特点，适合新一代便携式测试设备的发展需求。最后给出了系统在200MSPS数字存储示波器(DSO)上的实施结果。更多还原

【Abstract】 The software and hardware design of portable digital testing equipment based on TMS320VC5510 are presented, which is the newly efficient and low power consuming DSP of TI corporation. The system realizes the requirement of sample theorem when sampling the wide spectrum signal with an equivalent sample technology, integrates the LCD control core in CPLD and makes CPLD as LCD controller instead of specific LCD controller, and makes the colorful STN-LCD as terminal displaying facility. The system suits the development requirement of the new portable digital testing equipment with the specialities of low power consuming, high integration and good displaying interface. At last, the implement results of the system on the DSO having 200MSPS are presented.更多还原
