摘　　要：由于嵌入式设备应用的特定环境,在实时系统运行时产生的关键数据很难捕捉。为了更好地组织和分析系统参数,研发了一种既能挂载到嵌入式计算机系统总线,又能方便地支持调试设备下载数据的基于USB和PC I双接口电子存储设备,能使维护人员准确地把握设备的动态信息,从而进一步提高设备运行的稳定性。On account of the special condition of embed equipment application, it＇s hard to get the keydata of real- time system in course. In order to organize and analyze system parameters, a dual- interface electronic storage device that both can be mounted in embed- computer system bus,and supports debug equipment to download data is researched for the maintenance personnel can accurately grasp the dynamic information of equipment, and enhance the stability of equipment. This article describes the implementation of the dual- interface electronic storage device based on PCI and USB.
