摘要
文中提出基于PCI局部总线DSP通用数据采集系统设计方案,该方案采用TMS320VC5416作为外围核心处理单元,PCI2040作为PCI桥芯片,TLV1572作为数据转换器通过软件开发实现数据采集,具有高速度,低成本的优点。给出PCI接口硬件设计方法及关键点,介绍基于Windows2000操作系统的WDM驱动程序的结构及原理,驱动程序的基本功能的实现方法及应用程序与驱动程序的通信技术,介绍了实现DSP自启动的方式。
The article presents a universal system of data acquisition and processing based on PCI bus and digital signal processor. In this system, TMS320VC5416 is applied as a peripheral processing unit, PCI2040 as PCI-DSP is used as bridge, and TLV1572 as analog-to-digital converter (ADC). Data acquisition is achieved by software program. It has many characteristics, such as high speed and low cost. Design of PCI interface is introduced. It focus on the WI)M's framework and principle, the implementation way of the basic function of the device driver and the communication between the application program and device driver based on Windows2000 operating system.
