When it is integrated with communication and network technology, it will enhance the ability and intelligent of instruments and devices’network and communication. With the constantly developing of the information technology and increasing of the requirement of users, the Embedded System is entering into all kinds of fields of national product gradually and used extensively. The development of the electronic measurement instrument and device based on the embedded system will enforce the ability of communication, intercommunion, data procession and so on, at same time it can extent the application. The paper aims to study a design of the universal electronic measurement instrument software platform based on embedded system. The design of logic architecture for embedded system is studied based on the basic function and feature of universal electronic measurement instruments. The feature and development of embedded system based on ARM processor is studied. μC/OS-II embedded operating system is chose for t
