摘要
随着国家加快国产化系统软件的普及速度,越来越多的先进技术在国产平台上得到应用,其中在中标操作系统上使用SRIO串行总线进行路由配置及高速数据传输就是其中之一。在VPX通用平台,利用国产中标麒麟操作系统对桥芯片TSI721、交换芯片CPS1848和单片机互相配合,对平台内的所有具有SRIO总线的芯片进行路由配置,实现高速、灵活的数据传输。通过单片机实现上电后对板卡内SRIO速率,交换芯片端口复位等功能的配置,麒麟操作系统利用维护包进行路由配置实现对VPX平台下板内及板间的SRIO路由配置,并对SIRO端口速率、状态及各节点芯片间速率进行了详细地测试。
As the country accelerates the popularization of localized system software,more and more advanced technologies are applied on domestic platforms.Among them is the use of SRIO serial bus for routing configuration and high-speed data transmission on the NeoKylin operating system.The VPX universal platform is studied.The domestic NeoKylin operating system is used to bridge chip TSI721,switching chip CPS1848 and single-chip microcomputer to cooperate with each other,routing all the chips with SRIO bus in the platform to achieve high-speed,flexible data transmission.Configuration of the SRIO rate in the board and the switch chip port reset function after power-on is realized.The NeoKylin operating system uses the maintenance package to perform routing configuration to implement SRIO routing configuration within boards and between boards on the VPX platform.The SIRO port rate,status and inter-chip rate are tested in detail.
