摘　　要：面向为航空航天、舰船等移动高端装备提供受限条件下的高算力,嵌入式云、天基超算等集成多样化异构资源的集中式计算平台逐渐成为新一代高端装备电子信息系统的研究热点.现有商用以太网交换芯片面向数据中心、园区网等大规模高性能网络组网需求设计,难以满足移动高端装备集中式计算平台在能效、散热、业务优化等方面的敏捷交换需求.面向为移动高端装备中异构计算资源提供高能效、低功耗的敏捷连接能力,国防科技大学计算机学院提出了端到端敏捷交换解决方案,并自主研发了系列化银河衡芯敏捷交换芯片,是现有国产以太网交换芯片的有力补充.其中,YHHX-DS40嵌入式敏捷交换芯片面向数据流交换,集成4个万兆以太网接口和4个千兆以太网接口,支持应用层精细交换和异构资源统一连接,具有全线速交换能力,典型功耗仅为1.6W.Centralized computing platforms integrate diverse heterogeneous resources and provide high computing power under limited conditions,which now becomes a research hotspot of the new generation of electronic information system.Existing commercial ethernet switching chips are designed for large-scale and high-performance networks such as data center,which cannot meet the requirements of centralized computing platform.In order to provide high-efficiency and low-power agile connection capability for mobile high-end equipment,the College of Computer Science and Technology,National University of Defense Technology proposes an end-to-end agile switching solution,and independently developes YHHX(Yin He Heng Xin)-DS40 agile switching chip,which is a powerful supplement to the existing domestic Ethernet switching chips.YHHX-DS40 integrates four 10 Gigabit Ethernet interfaces and four Gigabit Ethernet interfaces with full line-speed switching capability.Besides,application layer fine-grained switching and unified connection of heterogeneous resources are supported only with 1.6W typical power consumption.
