This thesis adopts the embedded module of DIMM according to application and demand of the intellectual equipment, offer a kind of new thinking for the fact that the electron tube instrument is designed with the adoption of the key part in the course control system design.In recent years, in common use computer system represented by PC make the development at full speed from hardware and software, the speed of operation of the processor has already been up to the orders of magnitude of 1 billion times per second .As computer system too from single task, users' DOS only,character of interface central operating system, develop into multi-user , Windows 98 ,Windows NT ,Windows2000 , WindowsXP of many tasks with figure interface. The equipment with more and more demand for development of new developing IT industry has the characteristics that miniaturized , intelligent. In order to adapt to this development trend , have developed a kind of special system in the course of application of the computer system --Embedded computer system, namely embedded system. Embedded module from Germany created to accuse of belong to and just introduce at home, it is not still very extensive to use, but it has wide development space. After secondary development, offer various kinds of interface for intellectual equipment, such as combining mouth , one bunch of mouths , IDE , floppy drive , character liquid crystal , LCD ,etc..
Key words: Embedded System ; DIMM Module ; Interface Circuit
