LXI多功能仪器资源管理器设计

Design of resource manager of LXI multi-function instruments

本文使用M模块总线开发一种多功能LXI仪器,以ARM9处理器和Linux为核心设计了LXI接口载板,载板除提供完整的LXI接口功能和用于对多个M模块控制的接口控制器,还开发了对仪器内部的服务和各种资源管理的资源管理器。通过对资源的分类,资源管理器被划分为服务管理器、私有资源管理器、公有资源管理器和信息存储管理器四个组件。通过这四个组件协作,可以合理地管理仪器内部的服务和各种资源,同时为用户提供了简单友好的应用接口,极大地简化了仪器的操控、扩展及维护等方面的应用,为构建系统级的应用提供便利。

In this paper, a multi-function LXI instrument based on M module is designed and implemented. The ARM9 processer and Linux are the core to design LXI interface carrier board, providing the resource manager for the internal services and various kinds of resources, except the complete LXI interface functions and interface controller supporting multiple M modules. According to the types of oriented resources, the resource manager is divided into 4 components： services manager, private resource manager, public resource manager and information storage manager. Through the collaboration of the four components, all kinds of internal services and resources can be rationally managed. In addition, the user friendly interfaces are provided. Our design can greatly simplify the operation, extension and maintenance of the LXI instruments, meanwhile provide the facilitation for applications at system level
