摘　　要：无线投影机网关是投影机的附属设备,在PC与投影机之间建立无线连接,将PC的屏幕图像传输到投影机上,从而使PC摆脱与投影机之间的连线束缚。该网关设备在设计中采用的GX533是AMD的一款嵌入式x86处理器,GX533在机顶盒、网络终端、瘦客户机、廉价电脑等领域有着广泛的应用。分析了GX533处理器及其南桥控制器的结构原理,在此基础上介绍无线投影机网关的系统设计。Wireless gateway of projector is a type of accessory of projector, which builds a wireless connection between PC and projector and receives image data from PC on wireless LAN and sends image to projector. Thus PC can break away from the bondage of wire when connected to a projector. This device is designed with GX533 which is a x86 embedded processor from AMD. GX533 is widely used in top-set boxes, terminals, thin clients and low-price personal computers, The structure of GX533 is studied, and then the system design of the wireless oatewav is introduced.
