Description
本发明涉及智能手机技术,尤其涉及一种智能手机系统及其启动方法。
在手机芯片技术和电池技术飞速进步的带动下,带有操作系统(operation
system,OS)的开放式智能手机得到了飞速的发展。特别是以Apple公司推出的iPhone和Google公司推出的Android系统,以及老牌公司如Nokia的symbin
和微软的windows mobile等嵌入式操作系统,真正形成了智能手机操作系统三足鼎立的模式。各操作系统在定位上也有不同,如 Windows mobile
定位于商务应用而Android更着重于娱乐。
但是,现有的技术只能实现这些操作系统(软件)以单一方式存储并运行于手机设备(硬件),使智能手机只能运行单系统,而不能像个人电脑那样可以存储并运行多个不同的操作系统,在使用上有一定的局限,没法满足用户对多种操作系统及其使用习惯的需求。

图2为本发明智能手机系统较佳实施方式中双操作系统的安装流程图;
图3为本发明智能手机系统启动方法较佳实施方式的流程图。
以下将结合附图,对本发明的具体实施方式加以详细说明。
参考图1,本发明的较佳实施方式提供了一种双操作系统的智能手机系统,其内存(flash)包括以下分区:引导区(mini
Boot),用于系统硬件加电时的初始化和启动程序(bootloader)的加载,其存储地址段为0x0至0x40000;第一操作系统的启动程序区(OS1
bootloader),存储用于启动第一操作系统的bootloader,其存储地址段为0x4000至0x140000;第一操作系统的二进制代码区(OS1),用于存放第一操作系统OS1的二进制代码(binary
code),其存储地址段可由用户自定义;第一操作系统的用户数据区(OS1 user data),
用于存放第一操作系统的用户数据,其存储地址段可由用户自定义;操作系统的文件系统共享区(share
filesystem),用于多操作系统的共享文件存放,需要相同的文件系统,在本发明的较佳实施方式中使用FAT文件格式,其存储地址段可由用户自定义;第二操作系统的启动程序区(OS2

BBT),其存储地址段为0xCE00000至0xF040000;保留区(reserved),其存储地址段为0xF040000至0xFFFFFFF。
在本发明的较佳实施方式中,所述内存为NAND
flash,所述第一操作系统为Android,第二操作系统为Windows
Mobile,继续参考图2,将下载启动程序和双系统二进制代码到内存对应分区的步骤具体描述如下: S11、通过XDB(一种专用二进制下载工具)将NAND
flash格式化并建立好块表、坏块表和备份表;S12、通过XDB将BOLB文件(引导程序)下载到flash中的mini
boot区,以便在系统启动后进行bootloader的启动和加载;S13、启动mini
boot下载Android的3个二进制文件,分别是:zimage(Android的系统和驱动区)、system.img(Android的UI和资源文件存储区)以及userdata.img(用户数据的分区);S14、使用XDB下载Windows
Mobile的bootloader到flash中;S15、通过WM(Windows Mobile)的bootloader下载Windows
Mobile的OS。
参考图3是本发明智能手机系统启动方法的流程图,包括以下步骤:S21、智能手机系统上电开机后,在启动显示菜单选则要启动的操作系统类型;S22、如果用户选择了Android操作系统,就直接将Android的系统和驱动二进制代码(zimage
binary code)拷贝到指定的RAM(random access memory
随机存储器)中跳转到相应的地址,启动Android操作系统;S23、如果用户选择Windows
Mobile,其bootloarder就将WM系统启动程序(IPL binary code,WM
boot二进制代码)拷贝到指定的RAM,设置好CPU的跳转状态后直接跳转到RAM,启动Windows Mobile操作系统。
本发明有以下几大特点:1、操作系统随意切换,在系统启动时可以随意选择启动的操作系统类型,用户可以通过启动选择画面来选择需要启动的操作系统;2、成本低,双系统完全公用一套硬件,无需增加硬件成本;3、适用性强,手机用户可以按照自己的需求来选择自己喜欢的系统,如需要阅读商务文件Word就可以选择WM操作系统,需要娱乐性更强就可以选择Android系统;4、可扩展性强,可以通过本发明的智能手机系统来启动不同的操作系统,可以在任意双操作系统之间或是多个操作系统之间选择性启动。
本发明的较佳实施方式详述了Windows
Mobile和Android的双操作系统如何加载和启动,基于相同的原理可以扩展为其他双操作系统启动,例如Windows
mobile和OMS、Symbian和Android等,也可以扩展到多个操作系统选择性启动。
应当理解的是,对本领域普通技术人员来说,可以根据上述说明加以改进或变换,而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
