| Abstract: | 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 WDM'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. |
