"终端 /智能卡总线控制器，，负责新的体系机构下，接收来自各种用户接口设 备的中断信号， 如来自麦克风、 键盘、 手写笔、 触摸屏的中断信号， 并将所有 需要的数据， 转交给智能卡上的操作系统进行处理。 具体而言， 当用户使用这 些外部设备时， 如按键， 书写或点击触摸屏时， 这些设备产生中断信号， "终端 /智能卡总线控制器"中的 "输入 /输出集中控制器"接收到中断信号和相关的数 据， 并把他们传递给智能卡上的操作系统， 操作系统根据中断类型和相关的数 据， 进入相应的中断服务例程， 处理用户的请求。 "输入 /输出集中控制器"负责 将智能卡操作系统命令、 数据或地址信息， 传递给相应的用户接口设备， 比如 将多媒体相关数据传递给扬声器。
"终端 I智能卡总线控制器"中的 "存储集中控制器"主要协调移动终端所带 各种存储区， 和智能卡所带各种存储区的协调工作， 进行地址 /数据 /命令的解 释、 存取和控制； 存储设备具体包括外部扩展的 ROM, RAM或 FLASH, 以及用户 可以自由插拔的各种存储卡， 如 ScanDi sk, MMC ( Mul tiMedia Card ), U-Di sk 等等。 "存储集中控制器"可以接收通过 "智能卡集中控制器 "传来的， 来自智能 卡上的操作系统的命令、 数据或地址信息， 对各种存储设备进行数据访问和控 制， 并根据以上命令， 将访问到的数据和控制信息， 通过"智能卡集中控制器" 传递给智能卡上的操作系统。
"终端 /智能卡总线控制器"中的 "智能卡集中控制器"负责智能卡与其他几 个集中控制器之间的通信和控制。 具体而言， "智能卡集中控制器 "把智能卡与
"基带处理"之间的通信和控制信息， 比如 DPRAM的地址 /数据和协议转递给"基 带集中控制器，，或从"基带集中控制器，，得到相应的地址 /数据和协议信息； "智能 卡集中控制器 "得到来自 "输入 /输出集中控制器"的中断信号和相关数据， 并把 它们传递给^ ^载在智能卡上的操作系统。 "智能卡集中控制器"也将来自智能卡 上的操作系统的控制输入 /输出设备的数据传递给"输入 /输出集中控制器"； "智 能卡集中控制器，，还把来自智能卡上的操作系统的对外部存储设备进行操作和 控制的数据传递给"存储集中控制器"， 并把来自 "存储集中控制器"的数据传递 给智能卡上的操作系统。
总之， 作为总线控制器， 它协调控制每一个连接在总线上的设备， 包括承 载操作系统的智能卡， 保障命令、 数据和地址信息的畅通流动。
"终端 /智能卡总线控制器，，的初始化由每次移动终端开机上电后进行，由新 的体系结构下的移动终端的启动程序 （BootLoader )控制。
本发明中的移动终端的上电启动工作流程：
本发明中的移动终端的上电启动由终端上的启动程序 （BootLoader )来完 成， 其主要任务是对终端的各种硬件部件进行初始化， 测试软硬件协同并把相 关的终端的软件和硬件参数传递给承载终端操作系统和主要应用系统的智能 卡。
具体而言， 本发明中的移动终端的启动程序的流程由图 4所示， 包括以下 步骤：
步骤 S1 , 检查所述移动终端的硬件和固件设置；
步骤 S2 , 装载设置中断服务程序和装置驱动程序；
步骤 S3, 初始化所述移动终端的总线控制器， 并进行电源管理； 步骤 S4, 在上述过程中， 同时将检查、 装载的相关信息在系统中显示； 步驟 S5 , 将检测到的装置的信息传送给所述终端的智能卡， 将控制权交给 所述智能卡。
其主要功能包括对存储设备、 显示设备、 键盘或其他输入设备， 承载操作 系统的智能卡， "基带处理"部分等等的检查和测试， 并把相关信息传递给承载 终端操作系统和主要应用系统的智能卡， 其中对各种存储设备的检测包括： 类 型、 容量、 速度,对显示器设备的检测包括显示模式（单 /彩显）、 显示分辨率、 频率界限等等。 在这一过程结束后， 卡上的操作系统就会了解系统所处的外部 设备环境， 从而可以自动配置驱动程序， 当不能发现相应的驱动程序时， 会提 醒用户通过网上下载；
初始化上述各种设备及其他相关控制器；
提供基本的硬件中断服务控制功能；
支持各种外部设备的即插即用；
支持来自用户的设置， 比如用户可以将设备的类型等信息固定下来，或把 "即插即用，，和"自动设备检测"关闭， 这样移动终端不会再花时间做设备检测， 而已使用户有更短移动终端启动时间；
支持启动程序本身的动态更新。
在上述检查和测试、 驱动程序配置过程中， 也可以同时将相关信息进行显 示， 以方便用户了解设备启动的过程信息。
以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领 域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则 之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的权利要求范 围之内。
