The Research And Design Of Vehicle System Based On ARM And Windows Embedded CE 6.0

Nowadays automobiles have been an extension of our everyday life, the demands for safety and entertainment increase fast, automotive information system has changed from radio and tape drive to a powerful multimedia system which includes video and audio playback, TV reception, DVD player, Web browser, and many other functions. The research objective of this paper is automotive system, through the analysis and comparison of the existing embedded operating systems, embedded microprocessor, and combined with the specific applications requirements, the paper designs a automotive information system platform which is based on ARM architecture and Windows CE embedded operating system to achieve the main functions including GPS navigation, audio and video playback, Bluetooth communications, 3G wireless Internet access, and reversing camera. Through the modular design approach, the system is customizable and scalable.To meet speed, real-time, security, scalability and other numerous requirements of the embedded automotive system, this paper adopts a two-system solution (the major part and the minor part). The major system uses an ARM11 core S3C6410X MCU which is produced by Samsung, running Windows CE 6.0 embedded operating system; the minor system uses ST Microelectronics's STM32 family of chips within ARM Cortex-M3 core, and running the uC/OS-II RTOS system. According to their characteristics, every functional module is mounted in the two systems which using a serial interface for communication.At first, this paper introduced the background and development of the subject; then given an overview of embedded systems, and completed the choice of processors and operating systems; after that, was the description of the overall design and construction methods for hardware platform and software platform, including the core hardware module chip selection, circuit design and system migration; at last, was the introduction of several main modules's hardware and software design.In the test, the system functions can be normal operation, according with the main design desired.As the project involves a relatively wide, in addition to personnel and time constraints, some of the software and hardware modules are integrated with existing modules, at where the paper will be comment.
