Software updating scheme study for a telemetry intelligent terminal equipment with dual-CPU architecture system
For a telemetry intelligent terminal equipment with dual-CPU architecture system,a system software up-grade scheme based on Inotify mechanism and network file system(NFS)was formulated.Inotify is a mechanism for real-time monitoring file system changes in the Linux operating system.NFS is a network file system permitting us-ers to share files and storage resources between different computers or nodes.A detailed introduction was made on the design and realization of the upgrade scheme.The performance of the scheme was analyzed and evaluated.The results of test demonstrate the scheme has high real-time performance and reliability,and is able to effectively im-prove the upgrade efficiency of multi-CPU architecture of telemetry intelligent terminal equipment.
