Based On The Au1200 Car Multimedia Navigation System Hardware Design

With the development of modern information technology and its application in vehicle, various kinds of automobile navigation and multimedia player products come into being. Nowadays, there are so many kinds of automible electric application system, which have different functions. How to combine these functions such as GPS navigation, DVD player, wilreless Internet, drive monitoring and backcar radar in one more powerful system has been a problem to solve at present time.First, following automobile navigation & multimedia system's development trend and the requirement of users, an all-around solution is proposed in this paper, which is based on AU1200 processor, and an ADI DSP BF533 is used in system for vedio and audio processing. The main functions of the system include GPS navigation, DVD player, FM radio, drive monitoring and backcar radar, and so on. Main task of this thesis is system hardware design and debugging, which is under the environment of Cadence Allegro and Microsoft Platform Builder.The whole design flow includes: functional specification definition, general structure design, schematic design, PCB simulation design and system debugging.Chapter 1 gives a general description about the subject design of automobile multimedia & navigation system.Chapter 2 discusses the basic theory of realizing the design.Chapter 3 discusses functional specification definition and general structure design.Chapter 4 discusses the schematic design.Chapter 5 discusses PCB layout, simulation and system debugging.Chapter 6 summarizes the work and the technical trend.
