摘　　要：从高性能计算技术看,其发展主要受限于网络性能。在通信速度方面,面向存储及计算的网络,其发展都要比CPU落后一些。多功能芯片是一款用于航空领域的实现域内域间通信及分布式计算的嵌入式芯片,因此对芯片间的通信网络性能提出了新的要求。该文从多功能芯片应用需求出发,针对蒙皮系统对多功能芯片的组网要求,先简单介绍了自组网和分布式计算的概念和特点;然后从概念、协议、特点、性能等方面对当前主流的无线组网方式ZigBee、蓝牙、802.11ac、802.11ad(WiGig)、802.11ax和有线组网方式10G以太网、FC网络、InfiniBand、RapidIO、1394、Myrinet、Quadrics等进行了详细介绍,并比较了其特性和优缺点;最后根据多功能芯片对组网性能的需求,重点比较了WiGig无线组网方式和InfiniBand有线组网方式,得出WiGig无线组网方式符合蒙皮系统对多功能芯片的组网要求。Network performance has been a bottleneck restricting the development of high performance computing technology.The development of communication speed is far behind the development of CPU in both computation-oriented network and storage-oriented network.Multi-function chip is an embedded chip used in aviation to realize intra-domain communication and distributed computing.Therefore,new requirements are put forward for the performance of inter-chip communication network.Based on multi-functional chip application requirements,based on networking requirements for multi-functional chip skin system,we firstly introduce the concept and characteristics of networking and distributed computing,and then from concept,protocol,characteristics,performance and other aspects,discuss the current mainstream wireless networking mode including ZigBee,Bluetooth,802.11ac,802.11ad(WiGig),802.11ax and cable networking mode including 10G Ethernet,FC network,InfiniBand,RapidIO,1394,Myrinet,Quadrics in detail and compare their features and advantages and disadvantages.At last,WiGig wireless networking method and InfiniBand wired networking method are compared according to the multi-function chip’s demand for networking performance,and it is concluded that WiGig wireless networking method meets the multi-function chip networking requirements of skin system.
