GPS汽车便携式导航仪设计

In this paper based on the high-performance 32-bit ARM kernel S3C44B0X microprocessor, system hardware design. Hardware center plate reserves running an ARM systems necessary to expand the basic circuit, some common interface. System for portable portable equipment, in order to improve the reliability of the hardware equipments, it is compact, lightweight core processor with rich interface, so as to reduce outside circuit. A speech recognition system design module, which can realize human-machine conversation, humanization and intelligent. This device can obtain the real-time GPS module for further design parameters, portable GPS navigators provide basic muti _ function of data and information. Through the updated information, accurate positioning, vehicle navigation, improving the quality of the traffic safety.
