中文摘要：

以TMS320 DM6437为主控芯片,讨论一种基于DSP/BIOS类/微型驱动模型的图像采集与视频图形阵列（VGA）显示系统设计方法.在类/微型驱动模型中将驱动模型分为与硬件无关（类驱动）和与硬件相关（微型驱动）的两层,应用程序通过调用类驱动来间接调用微型驱动函数,从而达到控制图像采集及VGA显示的目的.实验结果表明：系统可以很好地实现DM6437的图像采集与VGA显示,达到了理想效果.

英文摘要：

In this system,TMS320 DM6437 is taken for the master chip.A method which based on DSP/BIOS class/mini driver model is discussed,so the image acquisition and display in video graphics array（VGA） monitor is realized.The class/mini driver is divided into two layers.One is device-independent layer（class driver） and the other is device-specific layer（mini driver）.In order to control the image acquisition and display in VGA monitor,class driver API is used to call the mini driver function indirectly.The results of the experiments based on DM6437 system are shown that the method can achieve ideal effect of image acquisition and display in VGA monitor.
