DSP多路同步数据采集板设计

Designing a Multipath Synchronous Data Acquisition Board Based on Digital Signal Processing

介绍基于DSP的同步采集与处理系统 ,分析并给出设计思想及原理框图 .该分析内容包括DSP板卡中DSP存储空间的具体配置 ,CPLD在DSP数据采集与处理系统中的逻辑控制方法 ,DSP片上串口与PC机RS2 32串行通讯的方法 ,以及DSP与虚拟仪器相结合 ,采用虚拟仪器进行DSP辅助信息处理的方法 .

Based on digital signal processing (DSP), the authors present a system for synchronous data acquisition and processing; and analyse and give design considerations and lock principle diagram. The analysis includes: the arrangement of memory space in DSP card, the logic control of CPLD in DSP data aequisition and processing system, the method of RS232 serial communication between DSP and personal computer, and also the combination of DSP and virtual instruments. The virtual instruments are adopted for carrying out DSP auxiliary information processing.
