具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例提供的一种终端的结构示意图，该终端可以为手机、平板电脑、笔记本电脑、UMPC(Ultra-mobile Personal Computer，超级移动个人计算机)、上网本、PDA(Personal Digital Assistant，个人数字助理)、计算机、智能手表等终端设备，本发明实施例以终端为智能手表为例进行说明，图1示出的是与本发明各实施例相关的终端的部分结构的框图。
本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对智能手表的结构造成限定。例如，该智能手表还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
如图1所示，该终端包括：存储器101、处理器102、多媒体组件103、电源组件104、输入\输出接口105。下面结合图1对终端的各个构成部件进行具体的介绍：
存储器101可用于存储数据、软件程序以及模块，存储器101主要包括存储程序区和存储数据区。其中，存储程序区可存储操作系统、至少一个功能所需的应用程序，比如声音播放功能、图像播放功能等；存储数据区可存储根据终端的使用所创建的数据，比如音频数据、图像数据、电话本等。此外，存储器101可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器102是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，通过运行或执行存储在存储器101内的软件程序和/或模块，以及调用存储在存储器101内的数据，执行终端的各种功能和处理数据，从而对终端进行整体监控。可选的，处理器102可包括多个处理单元，比如，包括应用处理器，或者包括应用处理器和微处理器；优选的，处理器102可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器102中。
多媒体组件103在终端和用户之间的提供一个输出接口的屏幕，该屏幕可以为触摸面板，且当该屏幕为触摸面板时，屏幕可以被实现为触摸屏，以接收来自用户的输入信号。触摸面板包括一个或多个触摸传感器以感测触摸、滑动和触摸面板上的手势。所述触摸传感器可以不仅感测触摸或滑动动作的边界，而且还检测与所述触摸或滑动操作相关的持续时间和压力。
电源组件104用于为终端的各个组件提供电源，电源组件105可以包括电源管理系统，一个或多个电源，及其他与终端生成、管理和分配电力相关联的组件。
输入\输出接口105为处理器102和外围接口模块之间提供接口，比如，外围接口模块可以包括但不限于物理键盘、功能键(比如音量控制按键、电源开关按键等)、轨迹球、鼠标、操作杆等中的一种或多种。
尽管未示出，终端还可以包括传感器、音频组件和通信组件等，比如，音频组件包括麦克风，通信组件包括WiFi(wireless fidelity，无线保真)模块、蓝牙模块等，本发明实施例在此不再赘述。
图2为本发明实施例提供的一种模式切换方法的流程示意图，该方法应用于终端，该终端中设置有第一作业系统和第二作业系统，当该终端处于省电模式时，第二作业系统处于运行状态，当该终端处于正常模式时，第一作业系统处于运行状态，参见图2，该方法包括以下几个步骤。
步骤201：当该终端处于省电模式时，若接收到第一切换指令，检测是否存在镜像文件；其中，第一切换指令用于将该终端由省电模式切换至正常模式；镜像文件包括该终端处于第一作业系统时的内存状态信息。
其中，第一作业系统和第二作业系统是不同的两个操作系统，且该终端的省电模式运行在第二作业系统上，该终端的正常模式运行在第一作业系统上。该操作系统是管理终端硬件资源，控制其他程序运行并为用户提供交互操作界面的系统软件的集合，负责管理与配置内存、决定系统资源供需的优先次序、控制输入与输出设备、操作网络与管理文件系统等基本任务。操作系统的种类很多，各种终端安装的操作系统可从简单到复杂。目前，流行的现代操作系统主要有Android、BSD、iOS、Linux、Mac OS X、Windows、Windows Phone和z/OS等。
该终端处于省电模式是指该终端的部分功能被限制使用，也即是，该终端处于省电模式时，该终端的一部分功能可以使用，另一部分被限制的功能则无法使用。
需要说明的是，该终端处于省电模式时被限制的部分功能可以由用户进行设置，也可以由终端进行默认设置。可选的，将终端中一些比较次要的功能设置为被限制使用的功能，而保留一些比较重要的功能可以在省电模式下使用。
比如，以智能手表为例，智能手表比较重要的功能可以包括时间显示、通话、发送和接收短信息等，比较次要的功能可以包括音视频播放、GPS定位、蓝牙连接等，因此，系统默认设置被限制使用的功能时可以将音视频播放、GPS定位、蓝牙连接等功能设置为被限制使用的功能。
另外，第一切换指令可以由用户触发，也可以由终端触发。当第一切换指令由用户触发时，用户可以通过第一指定操作进行触发，第一指定操作可以为按压操作、点击操作、滑动操作等等，比如，用户可以按压指定物理按键进行触发，或者通过点击或滑动正常模式切换区进行触发；当第一切换指令由终端触发时，终端可以在电池电量低于预设阈值时进行触发，也可以在时间处于指定时间范围时进行触发，也即是，当终端满足预设的第一触发条件时，终端可以触发第一切换指令。
再者，该镜像文件可以为该终端处于正常模式下的第一状态或者第二状态时的镜像文件，第一状态为该终端在本次开机之前的任一次开机后的初始状态，第二状态为 该终端在本次开机之前的任一次关机前的终止状态。
比如，以本次开机之前的上一次开机和关机为例，第一状态可以为该终端在本次开机之前的上一次开机后的初始状态，该初始状态是指该终端完成开机过程，且用户未开始使用时的状态；第二状态可以为该终端在本次开机之前的上一次关机前的终止状态，该终止状态是指用户使用结束，且该终端将执行关机过程之前的状态。
步骤202：若存在镜像文件，该终端终止第二作业系统的运行。
为了快速地将该终端由省电模式切换至正常模式，该终端可以检测是否存在镜像文件，并在存在镜像文件的情况下，可以直接根据镜像文件，快速地将该终端切换至正常模式，从而无需按照现有技术重新执行一次开机过程，缩短了切换时间，进而提高了用户体验。
具体的，当该终端检测并确定存在镜像文件时，该终端可以终止第二作业系统的运行，也即是，该终端停止运行在第二作业系统上的应用以及与第二作业系统相关的硬件，该应用包括运行在第二作业系统上的终端自身的进程、第三方应用等等。
步骤203：该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态。
其中，该终端在确定存在镜像文件之后，为了保证该终端中的一些器件在该终端的状态恢复之后可以正常使用，该终端还可以先对该终端中的一些器件进行初始化之后，再根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态，以将该终端由省电模式切换至正常模式。
该终端中的器件可以包括以下至少一个：蓝牙模块、wifi模块、多媒体组件、传感器、触摸面板、GPS定位芯片等等。预设器件可以事先进行设置，且预设器件可以是该终端中包括的器件中的至少一个，本发明实施例对此不作具体限定。
需要说明的是，当该终端检测不存在镜像文件时，该终端可以根据现有技术重新执行一次开机过程，将该终端切换至正常模式。
进一步的，在步骤203之前，该方法还包括步骤204。
步骤204：该终端判断该镜像文件的镜像形态，该镜像形态包括第一状态和第二状态。
由于该镜像文件的镜像形态可以包括第一状态和第二状态，且当该镜像文件的镜像形态为第一状态或者第二状态时，该终端根据步骤203恢复该终端的状态时会有所不同，因此，针对该镜像文件不同的镜像形态，分别进行阐述。
第一种情况、当该镜像文件的镜像形态为第一状态时，该内存状态信息包括关于至少一个硬件的硬件状态信息、以及关于至少一个应用的应用状态信息。
其中，该至少一个硬件是指该终端处于第一状态时，处于开启状态的硬件；硬件状态信息是指至少一个硬件在该终端处于第一状态时具体的状态参数。至少一个应用是指该终端处于第一状态时，处于开启状态的应用，该应用不仅可以包括终端系统自身的应用，还可以包括该终端中安装的应用。应用状态信息是指至少一个应用在该终端处于第一状态时具体的状态参数。
可选的，至少一个硬件的硬件状态信息可以为至少一个硬件的硬件标识，以及与每个硬件标识对应的状态参数；同理，至少一个应用的应用状态信息可以为至少一个 应用的应用标识，以及与每个应用标识对应的状态参数。
比如，以智能手表为例，当智能手表处于第一状态时，在硬件方面，若蓝牙模块开启，且与蓝牙BT-A0连接，则至少一个硬件包括蓝牙模块，当蓝牙模块的标识为ID1时，蓝牙模块的硬件状态信息可以为：ID1开启，且连接BT-A0；在应用方面，若邮箱开启，且处于收件箱页面，则至少一个应用包括邮箱，当邮箱的标识为ID2时，邮箱的应用状态信息可以为：ID2开启，且处于收件箱页面。
相应的，步骤203中，该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至内存状态信息所指示的状态，具体为步骤203a：该终端根据内存状态信息，将至少一个硬件恢复至硬件状态信息所指示的状态，以及将至少一个应用恢复至应用状态信息所指示的状态。
也即是，该终端根据镜像文件包括的内存状态信息，将该终端的至少一个硬件和至少一个应用，恢复至该终端在第一状态时至少一个硬件和至少一个应用所处的状态。
进一步的，参见图3，在步骤203a之后，该方法还包括：步骤205。
步骤205：该终端根据第一作业系统时的用户使用信息，将该终端的用户状态恢复至用户使用信息所指示的状态。
当该镜像文件的镜像形态为第一状态时，由于第一状态是该终端在本次开机之前的任一次开机后的初始状态，也即是，该终端完成开机过程，且用户还未使用的状态，所以内存状态信息中没有包括关于用户状态的用户使用信息，因此，在该终端按照上述步骤203a恢复之后，为了将该终端中的用户状态恢复至用户之前使用时的状态，该终端可以根据第一作业系统时的用户使用信息，将该终端的用户状态恢复至用户使用信息所指示的状态。
其中，用户使用信息可以是存储在终端中关于用户的信息，比如，可以存储在终端的存储器中，且用户使用信息可以包括用户对应终端的设定信息、用户开启或使用应用的信息，以及用户档案信息等等。比如，用户设定信息可以包括用户对终端的显示背景、应用图标位置、开关机时间、情景模式等等；用户开启或使用应用的信息可以包括用户开启的应用信息、以及开启的应用处于何种状态的信息等等；用户档案信息可以包括用户账号、密码、指纹、图像等等。
以智能手表为例，若用户使用信息包括：关机时间6:00、邮箱开启且处于收件箱页面、用户账号123456、密码abc，则主处理器根据上述用户使用信息，将该终端的关机时间设置为6:00，将邮箱开启并显示在收件箱页面，并在用户档案中记录用户账号为123456，密码为abc。
第二种情况、当该镜像文件的镜像形态为第二状态时，该内存状态信息包括关于至少一个硬件的硬件状态信息、关于至少一个应用的应用状态信息、以及用户使用信息。
相应的，步骤203中，该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统时的状态，具体为步骤203b：该终端根据内存状态信息，将至少一个硬件恢复至硬件状态信息所指示的状态，将至少一个应用恢复至应用状态信息所指示的状态、以及将该终端的用户状态恢复至用户使用信息所指示的状态。
需要说明的是，第二种情况中的至少一个硬件的硬件状态信息、至少一个应用的 应用状态信息、以及用户使用信息，与上述第一种情况中的至少一个硬件的硬件状态信息、至少一个应用的应用状态信息、用户使用信息一致，具体参见上述描述，本发明实施例在此不再赘述。
进一步的，参见图4，该方法还包括：步骤206-步骤209。
步骤206：当该终端处于正常模式时，若接收到第二切换指令，该终端检测是否存在镜像文件；其中，第二切换指令用于将该终端由正常模式切换至省电模式。
其中，第二切换指令可以由用户触发，也可以由终端触发。当第二切换指令由用户触发时，用户可以通过第二指定操作进行触发，第二指定操作与第一指定操作不同，且第二指定操作可以为按压操作、点击操作、滑动操作等等，比如，用户可以按压指定物理按键进行触发，或者通过点击或滑动省电模式切换区进行触发；当第而切换指令由终端触发时，终端可以在电池充电的电量高于等于预设阈值时进行触发，也可以在时间处于指定时间范围时进行触发，也即是，当终端满足预设的第二触发条件时，终端可以触发第二切换指令。
步骤207：若存在该镜像文件，该终端终止第一作业系统的运行。
当该终端检测存在镜像文件时，该终端无需制作镜像文件，即无需对第一作业系统下的内存状态信息进行镜像，可以直接终止第一作业系统的运行，也即是，该终端停止运行在第一作业系统上的应用以及与第一作业系统相关的硬件，该应用包括运行在第一作业系统上的终端自身的进程、第三方应用等等。
步骤208：若不存在该镜像文件，对该终端在第一作业系统下的内存状态信息进行镜像，得到镜像文件，并终止第一作业系统的运行。
为了保证该终端在下一次由省电模式切换至正常模式时，可以根据镜像文件，快速地进行切换，因此，若该终端检测不存在该镜像文件，该终端可以在切换至省电模式之前，对该终端在第一作业系统下的内存状态信息进行镜像，得到镜像文件，之后，再终止第一作业系统的运行。
其中，对该终端在第一作业系统下的内存状态信息进行镜像，得到镜像文件，可以包括：该终端清除内存状态信息中关于预设硬件的硬件状态信息，和/或关于预设应用的应用状态信息；对清除后的内存状态信息进行镜像，得到镜像文件。
也即是，该终端在制作镜像文件时，可以先将一些不必要的预设硬件和/或预设应用的状态信息进行清除，以使预设硬件和/或预设应用对应的状态信息处于闲置状态，从而只保留该终端处于正常模式时所需的最小内存状态信息，以减小镜像文件的容量大小。
进一步的，该终端对该终端在第一作业系统下的内存状态信息进行镜像之前，为了降低该终端的功耗，还可以将该终端的显示调整为暗屏状态，从而在暗屏状态下对内存状态信息进行镜像，得到镜像文件。
可选的，在得到镜像文件之后，该终端还可以对镜像文件进行压缩，以节省存储空间；相应的，该终端在需要根据镜像文件对该终端的状态进行回复时，可以再对镜像文件进行解压缩。
步骤209：该终端运行第二作业系统，以将该终端由正常模式切换至省电模式。
其中，将该终端切换至省电模式时，该终端可以关闭该终端处于省电模式时被限 制使用的功能，并负责管理处于省电模式时可以正常使用的功能。
需要说明的是，将该终端切换至省电模式的过程与现有技术一致，具体的切换过程可以参考相关技术，本发明实施例对此不作详细阐述。
需要说明的是，上述步骤206-步骤209与步骤201-步骤205不分先后顺序，该终端可以按照上述步骤201-步骤205，将该终端由省电模式切换至正常模式；或者，该终端按照上述步骤206-步骤209，将该终端由正常模式切换至省电模式。
进一步的，在上述步骤201-步骤209的过程中，若满足预设更新条件，该终端对该镜像文件进行更新；其中，预设更新条件包括以下至少一个：系统版本升级、镜像文件不完整或错误、镜像文件满足更新周期。
为了保证该终端可以根据新鲜且完整的镜像文件，及时地对该终端处于第一作业系统下的状态进行恢复，该终端可以检测镜像文件是否满足预设更新条件，并在镜像文件满足预设更新条件时，对镜像文件进行及时的更新。
其中，当该终端检测镜像文件是否满足系统版本升级时，可以检测该终端的操作系统是否进行了版本升级，若确定该终端进行了系统升级，则更新镜像文件。
另外，当该终端检测镜像文件是否不完整或错误时，该终端可以通过随机循环校验CRC码进行检测，和/或检测镜像文件的档头和档尾是否完整，和/或检测镜像文件在压缩和解压缩时的加密和解密是否正确，和/或检测镜像文件的长度、分段、总容量大小是否正确，和/或检测镜像文件的版本是否正确等等。
需要说明的是，镜像文件的版本与现有技术中软件的版本类似，可以通过版本号进行标识，或者通过镜像时间进行标识等等，本发明实施例对此不作具体限定。
再者，当该终端检测镜像文件是否满足更新周期时，是指该终端可以周期性的对镜像文件进行更新，每隔一个更新周期，对镜像文件进行一次更新，该更新周期可以事先进行设置。
上述图2-图4所示的模式切换方法的实施例中，该终端可以只包括一个处理器，该处理器器可以是应用处理器，该终端通过该应用处理器即可实现省电模式和正常模式之间的切换。
本发明实施例提供的模式切换方法，通过在接收第一切换指令时，检测是否存在镜像文件，并在存在镜像文件时，根据镜像文件将该终端的状态恢复至第一作业系统时的内存状态信息所指示的状态，从而将该终端快速地由省电模式切换至正常模式，减小了切换时间，并提高了用户体验。
图5为本发明实施例提供的一种模式切换方法的流程示意图，该终端中设置有主处理器和微处理器。当该终端处于省电模式时，微处理器处于运行状态，也即是，第二作业系统处于运行状态；当该终端处于正常模式时，主处理器处于运行状态，也即是，第一作业系统处于运行状态，参见图5，该方法包括以下几个步骤。
步骤301：当该终端处于省电模式时，若微处理器接收到第一切换指令，微处理器向主处理器发送第一唤醒指令；其中，第一切换指令用于将该终端由省电模式切换至正常模式。
具体的，该终端的主处理器与微处理器之间电性连接，比如，微处理器通过通用输入输出GPIO与主处理器的控制电源连接，当微处理器向主处理器发送第一唤醒指 令时，微处理器通过控制主处理器的电源信号的方式，向主处理器发送第一唤醒指令以开启主处理器的电源。
步骤302：基于第一唤醒指令的触发，主处理器执行上电流程。
当微处理器向主处理器发送第一唤醒指令之后，基于第一唤醒指令的触发，主处理器执行上电流程，也即是，基于第一唤醒指令的触发，为主处理器进行供电，使主处理器进行启动处于运行状态。
步骤303：主处理器检测是否存在镜像文件，该镜像文件包括该终端处于第一作业系统时的内存状态信息。
步骤304：若存在镜像文件，主处理器根据内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态。
具体的，当主处理器上电之后，为了快速地将该终端由省电模式切换至正常模式，主处理器可以检测是否存在镜像文件，在存在镜像文件的情况下，主处理器可以直接根据镜像文件包括的内存状态信息，快速地将该终端切换至正常模式，从而无需按照现有技术重新执行一次开机过程，缩短了切换时间，进而提高了用户体验。
进一步的，在步骤304之前，该方法还包括步骤305。
步骤305：主处理器判断该镜像文件的镜像形态，该镜像形态包括第一状态和第二状态。
由于该镜像文件的镜像形态可以包括第一状态和第二状态，且当该镜像文件的镜像形态为第一状态或者第二状态时，主处理器根据步骤304恢复该终端的状态时会有所不同，因此，针对该镜像文件不同的镜像形态，分别进行阐述。
第一种情况、当该镜像文件的镜像形态为第一状态时，步骤,304中主处理器根据该镜像文件，将该终端的状态恢复至内存状态信息所指示的状态，具体为步骤304a：主处理器根据该镜像文件，将至少一个硬件恢复至硬件状态信息所指示的状态，以及将至少一个应用恢复至应用状态信息所指示的状态。
进一步的，在步骤304a之后，该方法还包括：步骤306。
步骤306：主处理器根据第一作业系统下的用户使用信息，将该终端的用户状态恢复至用户使用信息所指示的状态。
第二种情况、当该镜像文件的镜像形态为第二状态时，步骤304中主处理器根据内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态，具体为步骤304b：主处理器根据内存状态信息，将至少一个硬件恢复至硬件状态信息所指示的状态，将至少一个应用恢复至应用状态信息所指示的状态、以及将该终端的用户状态恢复至用户使用信息所指示的状态。
需要说明的是，图5所示的实施例中的内存状态信息与上述图2-图4所示的实施例中的内存状态信息一致，具体参见上述描述，本发明实施例在此不再赘述。
具体的，以智能手表为例，若主处理器为ACPU，微处理器为MCU，智能手表由省电模式切换至正常模式的过程如图6所示，图中的内核为ACPU内核，图中包括的MCU环节、内核环节、操作系统环节为现有技术中按照重新开机的方式，将智能手表由省电模式切换至正常模式。本发明是在内核环节中的内核驱动初始化以后，即开始检测镜像文件，然后根据镜像文件进行硬件恢复、应用恢复，以及根据用户使用信息 对用户状态进行快速恢复。
进一步的，参见图7，该方法还包括：步骤307-步骤311。
步骤307：当该终端处于正常模式时，若主处理器接收到第二切换指令，主处理器向微处理器发送第二唤醒指令；其中，第二切换指令用于将该终端由正常模式切换至省电模式。
需要说明的是，当主处理器向微处理器发送第二唤醒指令时，与上述步骤301中微处理器向主处理器发送第一唤醒指令的方法类似，具体参见上述步骤301中的描述，本发明实施例在此不再赘述。
步骤308：主处理器检测是否存在镜像文件。
步骤309：若存在该镜像文件，主处理器执行下电流程。
当主处理器检测存在镜像文件时，主处理器无需制作镜像文件，也即是，无需对内存状态信息进行镜像，主处理器可以直接执行下电流程。具体的，当主处理器执行下电流程时，主处理器可以先对该终端的预设器件进行下电，之后，主处理器对自身和内存进行下电。
步骤310：若不存在该镜像文件，主处理器对该终端在正常模式下的内存状态信息进行镜像，得到镜像文件，主处理器执行下电流程。
为了保证该终端在下一次由省电模式切换至正常模式时，可以根据镜像文件，快速地进行切换，因此，若主处理器检测不存在该镜像文件，主处理器可以在切换至省电模式之前，对该终端在正常模式下的内存状态信息进行镜像，得到镜像文件，之后，主处理器执行下电流程。
其中，主处理器对该终端在正常模式下的内存状态信息进行镜像，得到镜像文件，可以包括：主处理器清除内存状态信息中关于预设硬件的硬件状态信息，和/或关于预设应用的应用状态信息；主处理器对清除后的内存状态信息进行镜像，得到镜像文件。
进一步的，主处理器对该终端在正常模式下的内存状态信息进行镜像之前，主处理器也可以将该终端的显示调整为暗屏状态，从而在暗屏状态下对内存状态信息进行镜像，得到镜像文件。
可选的，在得到镜像文件之后，主处理器还可以对镜像文件进行压缩，以节省存储空间；相应的，主处理器在需要根据镜像文件对该终端的状态进行回复时，可以再对镜像文件进行解压缩。
步骤311：基于第二唤醒指令的触发，微处理器将该终端切换至省电模式。
当主处理器将第二唤醒指令发送给微处理器时，基于第二唤醒指令的触发，微处理器开始运行，并将该终端切换至省电模式。其中，微处理器将该终端切换至省电模式时，微处理器可以关闭该终端处于省电模式时被限制使用的功能，并负责管理处于省电模式时可以正常使用的功能。
以智能手表为例，当微处理器将智能手表切换至省电模式时，微处理器关闭智能手表的GPS定位、蓝牙连接等功能，并负责管理智能手表的时间显示功能和通话等，具体的，智能手表由正常模式切换至省电模式过程可以参考图8所示。
需要说明的是，微处理器将该终端切换至省电模式的过程与现有技术一致，具体的切换过程可以参考相关技术，本发明实施例对此不作详细阐述。
需要说明的是，上述步骤307-步骤311与步骤301-步骤306不分先后顺序，该终端可以按照上述步骤301-步骤306，将该终端由省电模式切换至正常模式；或者，该终端按照上述步骤307-步骤311，将该终端由正常模式切换至省电模式。
进一步的，在上述步骤301-步骤311的过程中，若满足预设更新条件，主处理器对该镜像文件进行更新；其中，预设更新条件包括以下至少一个：系统版本升级、镜像文件不完整或错误、镜像文件满足更新周期。
需要说明的是，主处理器对该镜像文件进行更新时的预设更新条件与上述终端未同时包括主处理器和微处理器时所述的预设更新条件一致，具体参见上述描述，本发明实施例在此不再赘述。
本发明实施例提供的模式切换方法，通过微处理器接收第一切换指令，并向主处理器发送第一唤醒指令，使得主处理器基于第一唤醒指令的触发执行上电流程，之后，主处理器检测是否存在镜像文件，并在存在镜像文件时，根据镜像文件将该终端的状态恢复至内存状态信息所指示的状态，从而将该终端快速地由省电模式切换至正常模式，减小了切换时间，并提高了用户体验。
图9为本发明实施例提供的一种快速开机方法的流程示意图，参见图9，该方法包括以下几个步骤。
步骤401：当该终端接收到正常模式的开机指令时，该终端检测是否存在镜像文件，该镜像文件包括该终端处于第一作业系统时的内存状态信息。
其中，正常模式的开机指令可以由用户触发，用户可以通过指定操作进行触发。比如，以笔记本电脑为例，用户可以先打开电源开关，并在提供的几种开机方法中选择正常模式开机，从而使笔记本电脑接收到正常模式的开机指令。
另外，该镜像文件可以为该终端处于正常模式下的第一状态或者第二状态时的镜像文件，第一状态为该终端在本次开机之前的任一次开机后的初始状态，第二状态为该终端在本次开机之前的任一次关机前的终止状态。
步骤402：若存在该镜像文件，该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态。
具体的，为了快速地将该终端以正常模式进行开机，该终端可以检测是否存在镜像文件，在存在镜像文件的情况下，该终端可以直接根据镜像文件，快速地将该终端的状态恢复至至正常模式，从而无需按照现有技术的开机过程进行开机，从而可以缩短开机时间，进而提高用户体验。
需要说明的是，当该终端检测不存在镜像文件时，该终端可以根据现有技术执行一次开机过程，将该终端以正常模式进行开机。
进一步的，在步骤402之前，该方法还包括：步骤403。
步骤403：该终端判断该镜像文件的镜像形态，该镜像形态包括第一状态和第二状态。
由于该镜像文件的镜像形态可以包括第一状态和第二状态，且当该镜像文件的镜像形态为第一状态或者第二状态时，该终端根据步骤402恢复该终端的状态时会有所不同，因此，针对该镜像文件不同的镜像形态，分别进行阐述。
第I种情况、当该镜像文件的镜像形态为第一状态时，该内存状态信息包括关于 至少一个硬件的硬件状态信息、以及关于至少一个应用的应用状态信息。
其中，该至少一个硬件是指该终端处于第一状态时，处于开启状态的硬件；硬件状态信息是指至少一个硬件在该终端处于第一状态时具体的状态参数。至少一个应用是指该终端处于第一状态时，处于开启状态的应用，该应用不仅可以包括终端系统自身的应用，还可以包括该终端中安装的应用。应用状态信息是指至少一个应用在该终端处于第一状态时具体的状态参数。
可选的，至少一个硬件的硬件状态信息可以为至少一个硬件的硬件标识，以及与每个硬件标识对应的状态参数；同理，至少一个应用的应用状态信息可以为至少一个应用的应用标识，以及与每个应用标识对应的状态参数。
相应的，步骤402中，该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统运行时的状态，具体为步骤402a：该终端根据内存状态信息，将至少一个硬件恢复至硬件状态信息所指示的状态，以及将至少一个应用恢复至应用状态信息所指示的状态。
也即是，该终端根据镜像文件包括的内存状态信息，将该终端的至少一个硬件和至少一个应用，恢复至该终端在第一状态时至少一个硬件和至少一个应用所处的状态。
进一步的，参见图10，在步骤402a之后，该方法还包括：步骤404。
步骤404：该终端根据第一作业系统时的用户使用信息，将该终端的用户状态恢复至用户使用信息所指示的状态。
当该镜像文件的镜像形态为第一状态时，由于第一状态是该终端在本次开机之前的任一次开机后的初始状态，也即是，该终端完成开机过程，且用户还未使用的状态，所以内存状态信息中没有包括关于用户状态的用户使用信息，因此，在该终端按照上述步骤402a恢复之后，为了将该终端中的用户状态恢复至用户之前使用时的状态，该终端可以根据第一作业系统时的用户使用信息，将该终端的用户状态恢复至用户使用信息所指示的状态。
其中，用户使用信息可以是存储在终端中关于用户的信息，比如，可以存储在终端的存储器中，且用户使用信息可以包括用户对应终端的设定信息、用户开启或使用应用的信息，以及用户档案信息等等。比如，用户设定信息可以包括用户对终端的显示背景、应用图标位置、开关机时间、情景模式等等；用户开启或使用应用的信息可以包括用户开启的应用信息、以及开启的应用处于何种状态的信息等等；用户档案信息可以包括用户账号、密码、指纹、图像等等。
第II种情况、当该镜像文件的镜像形态为第二状态时，该内存状态信息包括关于至少一个硬件的硬件状态信息、关于至少一个应用的应用状态信息、以及用户使用信息。
相应的，步骤402中，该终端根据第一作业系统时的内存状态信息，将该终端的状态恢复至第一作业系统运行时状态，具体为步骤402b：该终端根据内存状态信息，将至少一个硬件恢复至硬件状态信息所指示的状态、将至少一个应用恢复至应用状态信息所指示的状态、以及将该终端的用户状态恢复至用户使用信息所指示的状态。
需要说明的是，第II种情况中的至少一个硬件的硬件状态信息、至少一个应用的应用状态信息、以及用户使用信息，与上述第I种情况中的至少一个硬件的硬件状态 信息、至少一个应用的应用状态信息、用户使用信息一致，具体参见上述描述，本发明实施例在此不再赘述。
进一步的，在上述步骤401-步骤404的过程中，若满足预设更新条件，该终端对该镜像文件进行更新；其中，预设更新条件包括以下至少一个：系统版本升级、镜像文件不完整或错误、镜像文件满足更新周期。
需要说明的是，该终端检测镜像文件是否满足预设更新条件的方法，与上述实施例提供的一种模式切换方法中的操作一致，具体参见上述实施例中的描述，本发明实施例在此不再赘述。
可选的，该终端包括主处理器和微处理器，主处理器用于运行第一作业系统，微处理器用于运行所述第二作业系统。可选的，该终端的主处理器与微处理器之间电性连接，比如，微处理器通过通用输入输出GPIO与主处理器连接。
本发明实施例提供的快速开机方法，通过在接收到正常模式的开机指令时，检测是否存在镜像文件，并在存在镜像文件时，根据镜像文件将该终端的状态恢复至内存状态信息所指示的状态，从而快速地将该终端以正常模式进行开机，减小了开机时间，并提高了用户体验。
图11为本发明实施例提供的一种模式切换装置的结构示意图，该装置中设置有第一作业系统和第二作业系统，当该装置处于省电模式时，第二作业系统处于运行状态，当该装置处于正常模式时，第一作业系统处于运行状态，参见图11，该装置包括：检测单元501、终止单元502和恢复单元503。
