    HX-DS09: A Customized Low Power Time Sensitive Networking Chip for High-End Equipment

    • 摘要: 时间敏感网络(time sensitive networking, TSN)作为一种可提供高带宽、高确定性传输服务的新型网络技术,近几年获得了国内外学术界和工业界的广泛关注与研究.然而,由于面向场景的TSN芯片定制困难,目前国内的TSN设备大多采用国外芯片或者基于国外核心IP通过FPGA实现,还没有全自主的TSN芯片可用于核心装备的网络升级换代.为此,OpenTSN项目组基于开源TSN芯片设计方法,面向高端装备的中小型数据交换网络需求,研制了一款低功耗的TSN芯片“枫林一号”.该芯片可提供亚微秒级时钟同步精度、单跳数据传输延迟(头进头出)和抖动保障能力,支持端、交换和交换端3种工作模式,功耗小于0.5W,可满足高端装备多样化的确定性组网需求.

       

      Abstract: As a new network technology that can provide high-bandwidth, high-deterministic transmission services, time sensitive networking (TSN) has received extensive attention and research from academia and industry in recent years. However, most domestic TSN devices currently use foreign TSN chips or hardware IP. There is no autonomous TSN chip available for network upgrading of core equipment. To this end, the OpenTSN team has developed a low-power TSN chip HX-DS09 for networks in high-end equipment. The chip can provide sub-microsecond synchronization accuracy, single-hop data transmission delay and jitter. HX-DS09 can work under endpoint, switching and switching endpoint mode, and its power consumption is less than 0.5W. It can satisfy the diversified deterministic networking needs of high-end equipment.
