摘要
针对图像处理中数据采集与处理的现状,介绍了基于DSP和PCI控制器的高速数据的实时采集、存储和处理的方法,并分别对电路原理图的硬件设计和PCI接口的软件设计做了阐述。该系统主要采用了DSP芯片来实现各种数字信号处理的算法程序,PCI总线控制器来实现PCI总线接口,以及CPLD作为控制DSP与PCI之间能够正常进行数据传输的枢纽,从而实现了数据的高速、高精度处理,为图像采集与处理提供了新的方法。
For the present situation of data acquisition and processing in image processing,this paper introduces a method for acquisition, storage and processing of high-speed data based on DSP and PCI controller. The hardware design of circuit schematic diagram and the software design of the PCI interface are discussed in detail. This systenl implements various algorithms of data signal processing by using DSP. PCI controller S5933 is used to realize the interface with PCI local bus and CPLD functions as a joint terminal of DSP and PCI controller, making this system transmit data correctly. As a resuh,a data acquisition and processing system fea- turing high-speed, and high precision is implemented and a new method for image acquisition and processing is provided.
