| 摘 要： | 介绍了基于USB接口的嵌入式Linux音频设备及图像采集的硬件系统结构,给出了驱动程序的设计方案及相关驱动程序的下载、配置、编译等过程,提出了一个用Philips公司的USB接口控制芯片ISP1161实现的低成本音频输出和视频采集嵌入式系统.由于ISP1161是一个既带主机控制器（HC）又带设备控制器（DC）的单片USB接口芯片,使系统用HC的向下端口能够与任何USB设备和有向上端口的USB集线器连接,用DC的向上端口能够与任何USB主机和有向下端口的USB集线器连接,这使得一个微处理器同时控制USB HC和USB DC成为可能,给他所在的系统带来了高度的灵活性.

| Abstract: | An USB interfacebased hardware system architecture which is embedded in Linux audio device and image acquisition.The design solution of driven programs and the process of download,dispute,compile of relative driven programs are given,and the achievement of a low cost audio output and video collecting embedded system that use the USB interface control chip: Philips ISP1161 are proposed.The ISP1161 is a single chip Universal Serial Bus(USB) Host Controller(HC) and Device Controller(DC).The downstream ports for the HC can be connected with any USB compliant USB devices and USB hubs that have USB upstream ports.The upstream port for the DC can be connected to any USB compliant USB host and USB hubs that have USB downstream ports.This makes it possible for a microprocessor to control both the USB HC and the USB DC at the same time.ISP1161 brings high flexibility to the systems. |
