基于ARM的汽车综合信息记录仪的研究

Study on Synthetical Information Recorder of Automobile Based on ARM

介绍一款基于32位处理器——ARM的新型汽车综合信息记录仪。从实际应用出发,利用运算速度较快的ARM作为该系统的控制中心,负责系统的运算、控制、管理等工作,其中涉及到操作系统的移植和系统电源的设计。该记录仪的整个系统设计分成LCD液晶驱动控制、语音报警功能、FLASH数据存储器以及USB接口、CAN总线、系统电源、系统保护功能6个模块的设计。以ARM的系统设计为主,从这6个模块与主芯片的接口论述整个系统的架构。

In this paper,a new type synthetical information recorder of automobile is introduced, which is based on 32 bit processor ARM. The thesis based on reality uses the fast calculation ARM as the control center, to in charge of the calculation, control, and management of the system, the transplant of operating system and the design of power supply are referred to. The complete system design of recorder is divided into six module design, that is the drive control of LCD, the function of voice alarm, FLASH data storage and the USB interface,CAN bus, system power supply, the function of system protection. The thesis gives priority to the system design of ARM, and discusses the whole structure of the system from the interface between the six module and the main chip. Partial programme is offered.
