The device driver is so critical to linux os that its wrong could cause the system breakdown . this dissertation analyzes the elementary operating principle of the device driver in linux , expatiates on the memory management , interrupt processing , i / o port and dma processing Linux设备驱动程序在linux操作系统中至关重要,它的缺陷严重时可以直接导致系统的崩溃。论文分析了linux设备驱动程序的基本工作原理,讨论了开发中经常会碰到的内存管理、中断处理、 i o端口、以及dma处理等问题。
In the first step , the author introduces the rtxc real time operation system and illustrate in detail the boot code design of arm processor , secondly , the author offers a whole structure under this operation system and explains the function of this software in terms of four relative tasks , in which the signal processing module , interface interrupt processing module , system operation measuring and controlling module and rc & lc information processing module are illustrated at length 先介绍了实时操作系统rtxc ,详细阐述了arm处理器启动代码程序的设计,然后给出了在此操作系统下软件设计的整体结构,分四个任务分别阐述此软件功能,其中详细介绍了信令处理模块、接口中断处理模块、系统运行监测模块和rc消息lc消息处理模块。
During the design of vxi - bus serial controller module , the functions of vxi - bus including time - sequence for vxi interface , resource management , interrupt process , bus arbitration , are accomplished . to advance the performance and stability , the fpga technic is used to implement the kerneled code including serial bus time - sequence switching to vxi interface time - sequence , the uart , the parameterized baud generator and “ pipeling frame ” . the handle type of data transfer bus for vxi - bus is researched thoroughly , and the format of serial data transfer is designed 在vxi总线串行控制器设计中,实现了vxi总线控制器的基本功能,包括vxi总线接口时序、总线仲裁、超时处理等;同时利用先进的fpga技术实现了串行总线时序向vxi总线时序的转换、通用异步收发器( uart ) 、参数化波特率发生器、流水线结构等功能模块;在设计中还深入研究了vxi总线数据传输的各种操作类型,制定了串行数据传输的编码格式。
Firstly , this paper briefly describes the pda " s bsp , and summarizes the xgw system , including program schedule , memory management characterfe graphic output , then concentrates on perfecting the xgw system for meeting with the pda specific application requirements , including soft _ keyboard input , handwriting input and gui graphic modules . at the same time , the pda " s software structure , the answers to problems and pda " s interrupt process are given in details 文章首先介绍了本pda系统的bsp模块,而后概述了xgw平台系统,包括程序调度、内存管理和字符图形输出,重点阐述了针对本pda系统的具体应用需求,对xgw原有平台的完善,主要是软键盘输入、手写体输入、 gui图形控件的开发;同时给出本pda系统的软件结构以及难点问题的解决方法和系统中的中断处理。
