摘　　要：针对Internet与WSN这两种网络协议转换时网关的传输带宽受限问题,设计了一种多核嵌入式网关.使用双口RAM存储器CY7C026作为公共存储区域、ATmega128(L)单片机作为处理器模块、RTL8019AS网络控制器作为网卡模块、CC2420射频收发芯片作为无线通信模块;采用具有精简网络协议栈的Nut/OS实时操作系统作为软件平台.通过多个处理器并行处理数据方式,最终实现Internet与WSN无缝连接.实验表明,系统能够稳定运行,并有效地提高传输带宽.Focusing on the bandwidth limitation of transmission between Internet and WSN （wireless sensor network）, a multi-core embedded gateway was designed. The gateway was designed using dual-ported memory CY7C026 as the public memory block, ATmega128 （L） as the processor module, RTLS019AS as the full-duplex Internet controller, and CC2420 RF chip as the wireless communication module. Nut/OS was utilized to reduce network protocol. Using multiple chips for parallel processing, seamless link could be enforced between Internet and WSN. The experimental results show that the system can provide high stability and improve the transmission bandwidth.
