The Design Of Wireless Gateway Based On Multi-core SoC Processors

With the development of network technology and embedded technology and theapplication of wireless network technology, the habits of the people’s work and living aregoing to change. The growing demand of the need of networking and mobility for dataservices on wireless networks become more and more urgent. However, the singleapplication scenarios and the simple features of traditional embedded gateway device makeembedded gateway is only suitable for home or small office, which don’t meet the needs oflarge enterprises and carriers. Traditional wireless network, has also been unable to meetthe growing requirements of the people on the mobile business. New developmentcharacteristics of embedded technology and Wi-Fi technology can be a good solution to thedrawbacks of traditional embedded gateway,which is an important trend for the futuredevelopment of embedded systems and WLAN.With understand the current development of embedded products and the gatewaydevice background,this paper analyzes the development status of the current wirelessgateway core technology at home and abroad, as well as the future direction firstly. Then,the paper research the overall requirements and objectives of the wireless gateway, anddesign the the wireless gateway hardware and software platform and system functions. Thedevelopment of the wireless gateway be based on embedded Linux operating system, andthe hardware is TI’s PUMA5and network processor RTL8198which merge Wi-Fitechnology. Them are based on the multi-core processor technology and SoC and. Wirelessgateway system hardware platform based on the research and design of the core functionsof the wireless gateway, seeks discussed in detail in the dual-architecture design based onthe design of the software. Meanwhile, the network performance of the design has beentest. Finally, it is summarized and discussed some of the experience and inadequate designprocess.In this paper, the design of wireless gateway implements a wired LAN and wirelessLAN network seamlessly links, and provide efficient Wi-Fi access and network packet data processing, and improve the main processor business response rate. The design is based onthe new features and advantages of the embedded technology and Wi-Fi technology, adual-processor architecture work together to build a new scalable, multi-purpose andhigh-performance embedded wireless gateway system.
