具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
实施例
图1为本申请实施例提供的程序升级方法的流程图，本实施例可适用于在电子设备在正常工作时，电子设备中的应用程序进行升级的情况，该方法可以由本申请实施例提供的程序升级装置来执行，该装置可采用软件和/或硬件的方式实现，并一般可集成电子设备中。如图1所示，具体包括：
S110，运行第一应用程序组。
其中，第一应用程序组是电子设备实现正常工作所需的应用程序的集合。可以包括至少一个应用程序。
具体的，电子设备为电源设备，可以是由一个或多个电源模块集成的电源设备。电源设备用于为通讯设备供电。
在一个示例性实施方式中，所述运行第一应用程序组，包括：运行所述第一应用程序组中的第一主应用程序。
其中，应用程序组包括主应用程序和至少一个非主应用程序。其中，主应用程序用于实现电子设备的功能。主应用程序在运行的过程中需要获取至少一个非主应用程序的运行结果(可以是运行的最终结果，也可以是运行的中间结果)，才能正常运行，或者继续运行。主应用程序的运行与应用程序组中的其他非主应用程序相关联。
可以理解的是，运行第一应用程序组，实际是指从第一应用程序组中第一主应用程序的首地址开始运行，更具体的是，将第一主应用程序加载在处理器(Central Processing Unit，CPU)的内存中开始运行。同时在第一主应用程序的运行过程中可能会涉及第一应用程序组除第一主应用程序之外的第一非主应用程序的运行或历史运行提供的运行结果。
具体的，运行第一应用程序组的过程中，第一主应用程序一直在运行，并等待触发信号进行响应，触发信号可以是第一非主应用程序发出的。其中，一次响应结束可以认为是第一主应用程序的当前轮次任务执行完成。
示例性的，主应用程序为反馈式控制输出设定直流电压功能的控制程序，其中，主应用程序需要获取反馈值，并将反馈值进行处理，得到相应的控制指令，并发送至至少一个外设设备，以控制各外设设备实现升高或下降电路中的电压，从而保证电压稳定在目标直流电压值，其中，反馈值是非主应用程序运行得到的。此外，主应用程序和非主应用程序是在不同时刻运行的。但非主应用程序的升级会影响到主应用程序运行的结果或者运行的过程，仅有非主应用程序的升级，现有技术中的电源模块同样需要重新启动，无法实现电源模块正常工作过程中进行程序在线升级。从而仅有非主应用程序的升级，同样需要重新开始运行主应用程序，才能保证升级后的非主应用程序关联到主应用程序的运行的结果或者运行的过程上，以保证主应用程序的输出(如反馈控制指令)的准确。
相应的，主应用程序的当前轮次任务执行完成可以是指一次反馈控制输出完成，例如，当负载电路的负载电压出现瞬态变化时，主应用程序需要根据该瞬态变化产生的反馈值，发送相应控制指令，控制外设设备对该瞬态变化进行响应，可以理解的是，发出控制指令的时候可以认为一次反馈控制输出完成，即主应用程序的当前轮次任务执行完成；或者可以在负载电路的负载电压重新稳定在目标直流电压值时，认为一次反馈控制输出完成，即主应用程序的当前轮次任务执行完成。此外，还有其他情况，可以根据需要进行设定，对此，本申请实施例不作具体限制。
在一个示例性实施方式中，所述应用程序组存储区用于存储主应用程序和非主应用程序，所述主应用程序通过加载到内存中运行，所述非主应用程序和所述引导加载程序通过加载到所述内存中运行，或者在所述第一存储区和所述第二存储区形成的存储区域中运行。
主应用程序加载在内存中运行，可以提高主应用程序的实时性。非主应用程序和引导加载程序的实时性要求不高，可以选择加载在内存中运行，或者直接在闪存(Flash)中运行。此外，存储区中除了存储应用程序之外，还存储应用程序所需的数据或者应用程序输出的运行结果等。
通过配置应用程序在内存中运行，可以提高应用程序的实时性，通过将除主应用程序以外的应用程序配置在Flash中运行，可以合理分配计算资源，减少内存的负担，以及减少IO次数，进而提高运行在内存中的主应用程序的实时性。
S120，在所述第一应用程序组运行的过程中，获取待升级应用程序的升级包，并根据所述升级包更新第二应用程序组中的待升级应用程序，所述第一应用程序组与所述第二应用程序组相同，所述第一应用程序组位于第一存储区，所述第二应用程序组位于第二存储区。
待升级应用程序是指应用程序组中需要升级的应用程序。升级包用于对至少一个待升级应用程序进行升级，包括至少一个待升级应用程序对应的更新数据。在对第二应用程序组中的待升级应用程序进行升级的过程中，第一应用程序组始终保持正常运行。也即第一应用程序组的运行和第二应用程序组中的待升级应用程序的升级是同时进行的。
第一应用程序组与第二应用程序组相同，表明第一应用程序组和第二应用程序组可以实现相同的功能，电子设备可以替换运行第一应用程序组和第二应用程序组，均可以实现正常工作，例如，为通讯设备正常供电。示例性的，第一应用程序组和第二应用程序组均用于电源设备基于反馈式控制实现输出设定直流电压转换功能，以为通讯设备提供目标直流电压。第一应用程序组和第二应用程序组在电源设备出厂时相同，同时，每次更新完毕后，第一应用程序组和第二应用程序组相同。
第一应用程序组位于第一存储区，第二应用程序组位于第二存储区，表明第一应用程序组和第二应用程序组分别存储在不同位置。第一存储区和第二存储区均为存储区域中的区域，且存储的数据相同。存储区域实际为Flash上的区域。
在一个示例性实施方式中，如图2所示，所述第一存储区和所述第二存储区均分别包括引导加载程序存储区和应用程序组存储区，所述第二存储区与所述第一存储区相同，应用程序组位于所述应用程序组存储区，引导加载程序位于所述引导加载程序存储区，所述引导加载程序用于根据升级包更新待升级应用程序，以及引导加载应用程序组。
具体的，引导加载程序(Bootloader)为在操作系统内核运行之前运行的程序，用于初始化硬件设备和建立内存空间的映射图等，以搭建操作系统内核运行所需的软硬件环境，以便在该环境中正确调用操作系统内核。而应用程序组的应用程序均以操作系统为运行环境。引导加载程序是在应用程序组运行之前运行，具备对应用程序组进行升级的权限，从而引导加载程序用于根据升级包更新待升级应用程序。
第一存储区和第二存储区均存储有引导加载程序和应用程序组，也即单独获取每个存储区中的存储数据均可以实现独立正确运行应用程序组，从而实现电子设备的正常运行。可以理解的是，第一存储区和第二存储区不仅互为备份，每个存储区中存储的都是可正常运行的程序。
通过配置两个存储区，每个存储区均存储有应用程序组和引导加载程序，保证每个存储区中的程序可以独立正常运行，而且，保持两个存储区的程序同步，保证两个存储区中的程序可以相互替换运行，从而保证应用程序组中的程序在线升级。
在一个示例性实施方式中，所述应用程序组存储区包括至少一个功能单元区，不同功能单元区分别存储所述应用程序组中不同应用程序，不同功能单元区分别存储在不同Flash区。
示例性的，对应用程序组存储区按照应用程序进行划分，具体如图3所示，可以建立应用程序与功能单元区的对应关系，方便识别待升级应用程序的存储位置，从而，可以实现仅对待升级应用程序对应的功能单元区进行更新，减少程序升级的工作量，提高程序升级的效率。示例性的，一个功能单元区为一个Flash区，具体是Flash扇区。可以为每个Flash区分配唯一数字编号，一个Flash区可能是一个Flash物理扇区或多个Flash物理扇区，即功能单元区与Flash区的数字编号存在单一映射关系。应用程序组 存储区包括下述至少一项：存储主应用程序的功能单元区、存储外设初始化程序数据的功能单元区和存储任务调度程序数据的功能单元区等。
其中，升级包中包括应用程序组存储区中全部功能单元区的数据，既包括不需要更新的功能单元区的数据，同时还包括需要更新的功能单元区的数据。其中，不需要更新的功能单元区的数据与应用程序组存储区中相应功能单元区的数据相同，需要更新的功能单元区的数据与应用程序组存储区中相应功能单元区的数据不同。可以直接将升级包中的数据写入到应用程序组存储区，由此，应用程序组存储区中需要更新的功能单元区的数据发生更新，而不需要更新的功能单元区的数据没有变化，从而实现对应用程序组的程序进行升级。
此外，还可以通过升级包获取需要更新的功能单元区的信息，并仅对应用程序组存储区中需要更新的功能单元区进行更新，实现增量更新程序。
在一个示例性实施方式中，所述根据所述升级包更新第二应用程序组中的待升级应用程序，包括：获取与所述升级包匹配的至少一个待更新功能单元区；通过位于所述第一存储区的引导加载程序区中的函数或功能接口，对所述第二存储区中各所述待更新功能单元区中数据进行擦除，以及将所述升级包写入。
其中，待更新功能单元区存储待升级应用程序，也即待更新功能单元区是应用程序组存储区中需要进行更新的功能单元区。一个待更新功能单元区对应存储一个待升级应用程序。待更新功能单元区的信息用于确定待更新功能单元区，具体的，可以是指待更新功能单元区的标识信息，例如在存储区域中的存储位置或待更新功能单元区的区编号等。
待升级应用程序升级实际是将升级包中对应的更新数据更新到存储待升级应用程序升级的待更新功能单元区中，具体的，是对该待更新功能单元区进行擦除，并将升级包中对应的更新数据写入。
可以理解的是，当前运行的程序为第一应用程序组，也即此时第一应用程序组的运行环境为第一存储区的引导加载程序搭建的，而应用程序组的升级是由引导加载程序实现。函数或功能接口用于实现应用程序组存储区的擦除和写入等功能。可以通过调用引导加载程序存储区中的功能接口或函数，实现运行引导加载程序对各个待更新功能单元区中数据进行擦除，以及将升级包写入，从而实现对各待更新功能单元区中存储的待升级应用程序进行升级。
通过为仅对需要更新的待更新功能单元区进行更新，从而实现增量升级，避免对全部应用程序组存储区进行更新，导致更新工作量大，效率低的情况，从而提高应用程序组存储区更新的效率，以及提高应用程序升级速度。
在一个示例性实施方式中，所述获取与所述升级包匹配的至少一个待更新功能单元区，包括：接收与所述升级包匹配的至少一个待更新功能单元区的信息；或者根据所述升级包和所述应用程序组，确定与所述升级包匹配的至少一个待更新功能单元区的信息。
具体的，可以直接接收与电子设备通信的升级交互单元发送的待更新功能单元区的信息，其中，升级交互单元可以通过有线或者无线与电子设备通信。升级交互单元可以接收存储有应用程序组存储区中存储数据的.out文件或hex文件，用于存储应用程序组对应的代码数据，以及升级包文件，进行比对，查询存在差异的功能单元区，确定升级包匹配的至少一个待更新功能单元区的信息，例如可以通过有线(如U盘传输)或无线网络传输等方式接收文件。
或者，由电子设备直接对应用程序组存储区中存储数据的.out文件或hex文件，以及升级包文件进行比较，查询存在差异的功能单元区，确定升级包匹配的至少一个待更新功能单元区的信息。
通过将升级包与应用程序组存储区中存储数据进行对比，从而确定需要更新的待更新功能单元区，可以准确确定待更新功能单元区，从而实现增量升级，避免对全部应用程序组存储区进行更新，导致更新工作量大，效率低的情况，从而提高应用程序组存储区更新的效率，以及提高应用程序升级速度。
在一个示例性实施方式中，内存中包括主应用核心信息固定区和主应用核心信息预留区，所述主应用核心信息固定区用于存储主应用程序运行所需的当前核心参数，所述主应用核心信息预留区用于存储主应用程序运行所需的扩展核心参数，各核心参数的内存地址固定，所述核心参数用于第一主应用程序和第二主应用程序使用。
其中，当前核心参数可以是指应用程序组中主应用程序所需的静态变量或全局变量。主应用核心信息固定区用于存储当前核心参数。扩展核心参数可以是指应用程序组中主应用程序当前不需要的数据，但未来所需的静态变量或全局变量，例如，可以是在升级之后主应用程序所需的静态变量或全局变量，该扩展核心参数的初始值为0，待后续需要进行赋值。主应用核心信息预留区用于存储扩展核心参数。当前核心参数和扩展核心参数均用于第一主应用程序和第二主应用程序使用。
主应用核心信息固定区和主应用核心信息预留区的存储位置固定，且其中存储的每个核心参数(包括当前核心参数和扩展核心参数)的内存地址也固定。其中，扩展核心参数的初始值为0，主应用程序需要新增一个核心参数，该核心参数为当前核心参数(如x)的数值加1，可以对扩展核心参数赋值为x+1，由此，扩展核心参数作为主应用程序的静态变量或全局变量在主应用程序运行过程中使用。
具体的，为了保证应用程序组切换前后的应用程序组关联的核心参数的连续性，也即为了切换前的应用程序组关联的核心信息能被切换后的应用程序组使用，在本申请实施例中即为了第一应用程序组关联的核心参数能被第二应用程序组使用，需要将这些核心参数存储在固定的预设内存中的存储位置，以便第一应用程序组和第二应用程序组均可以从该预设内存中的存储位置处获取。将核心参数直接配置与内存中，可以提高核心参数的获取速度，从而提高主应用程序切换运行的速度。
通过预先配置主应用核心信息固定区和主应用核心信息预留区，以便第一应用程序组关联的核心参数能被第二应用程序组使用，保证在第一应用程序组和第二应用程序组切换运行过程中核心参数的连续性，从而保证电子设备稳定工作。
S130，所述第二应用程序组中的待升级应用程序更新完毕，则运行更新后的第二应用程序组，并根据所述升级包更新所述第一应用程序组中的待升级应用程序。
第二应用程序组中的待升级应用程序更新完毕，表明本次程序升级完成，本次程序升级需要升级的至少一个待升级应用程序均已升级完成。
运行更新后的第二应用程序组，即电子设备由运行第一应用程序组，变为运行更新后的第二应用程序组，实际是由运行升级前的应用程序组变为运行升级后的应用程序组，从而实现在线升级程序。
将升级包继续更新第一应用程序组中的待升级应用程序，保证更新后的第一应用程序组与更新后的第二应用程序组相同，以进行后续再次升级。
本申请实施例所提供的程序升级方法、装置、电子设备及存储介质，通过在运行第一应用程序组时，对与第一应用程序组相同的第二应用程序组进行更新，并在第二应用程序组更新完毕后，运行第二应用程序组，实现应用程序组可以在工作时升级，解决了现有技术中应用程序在升级时无法正常工作的问题，实现应用程序组可以实时升级，并在升级的同时保证正常工作，从而提高配置应用程序组的设备的可靠性和稳定性，而且无需配置多个硬件设备以实现程序在线升级，降低程序升级的成本，并提高程序升级的效率。
在一个示例性实施方式中，所述运行更新后的第二应用程序组，包括：对更新后的第二应用程序组进行校验；如果计算得到的校验码与所述升级包匹配的校验码相同，则校验通过，并运行更新后的第二应用程序组。
具体的，更新后的程序需要经过校验。校验用于判断第二应用程序组是否正确升级。其中，与升级包匹配的校验码可以是与升级包一起下发的数据。校验通过，表明保证第二应用程序组已根据升级包正确升级。
其中，校验方式可以是获取第二应用程序组的数据进行循环冗余校验码(Circulating Redundancy Code，CRC)计算，并与升级包匹配的校验码进行比较。如果计算得到的校验码与升级包匹配的校验码相同，则校验通过；否则，校验失败。如果确定校验失败，则继续运行第一应用程序组，并反馈校验失败消息，之后可以继续更新第二应用程序组，或者，将第一应用程序组写入第二存储区中应用程序组存储区，以使第二应用程序组退回未升级状态，保持与第一应用程序组相同。
通过对第二应用程序组进行校验，并在第二应用程序组正确升级之后，运行更新后的第二应用程序组，保证第二应用程序组正确升级之后开始运行，从而实现电子设备正常运行，提高系统工作的稳定性。
在一个示例性实施方式中，在获取待升级应用程序的升级包之后，还包括：更新升级标志位为升级； 所述运行更新后的第二应用程序组，包括：如果确定所述升级标志位为升级，则判断所述第二应用程序组中的第二主应用程序是否为待升级应用程序；如果是，则在所述第一主应用程序的当前轮次任务执行完成时，运行更新后的第二主应用程序，并将所述升级标志位更新为非升级；否则，运行所述第二主应用程序，并将所述升级标志位更新为非升级。
具体的，升级标志位用于判断是否存在程序升级。获取升级包之后，会对应用程序组中程序进行升级，此时可以通过配置升级标志位，表示应用程序组处于升级状态。
升级标志位为升级，表明应用程序组中存在未运行的已升级的应用程序组。升级标志位为非升级，表明应用程序组中不存在已升级的应用程序组，或者已升级的应用程序组已经运行。
第二主应用程序为第二应用程序组中的主应用程序。运行第二应用程序组实际是将第二主应用程序加载在内存中，从第二主应用程序的首地址开始运行。
第一主应用程序可以包括循环子程序，或者中断响应子程序。第一主应用程序的当前轮次任务执行完成，可以是指循环子程序运行完成，或者中断响应子程序运行完成。示例性的，第一主应用程序为反馈控制输出恒定直流电压的程序，第一主应用程序的当前轮次任务执行完成可以是指当前反馈控制任务执行完成，即响应反馈值调整电压输出控制指令，直至电路中直流电压调整为目标直流电压，也即响应子程序运行完成。
如果第二主应用程序进行升级，则在第一主应用程序运行完成时，运行更新后的第二主应用程序。如果第二主应用程序未进行升级，则可以由运行第一主应用程序直接替换为运行第二主应用程序。可以理解的是，第一主应用程序和未升级的第二主应用程序是相同的，由此，在第二主应用程序未升级时，可以直接替换运行，而且运行过程中可以直接使用第一主应用程序的中间结果，不会影响程序执行的完整性，也不会影响系统的稳定性。当第二主应用程序升级后时，和第一主应用程序不同，若在第一主应用程序运行过程中，直接替换为第二主应用程序，导致第一主应用程序的未完整执行，而且，第二主应用程序可能无法得到与第一主应用程序相同的结果，甚至是相反的结果，导致系统运行出现问题。
将升级标志位更新为非升级，表明升级后的应用程序组已运行，可以重新接收升级包进行下一次升级。
通过配置升级标志位，以及根据升级标志位的状态判断是否有进行过程序升级，若有程序升级时，进一步判断主应用程序是否升级，如果没有升级可以直接运行升级后的应用程序组中的主应用程序，如果升级，需要等待未升级的主应用程序的当前轮次任务运行完成后，替换运行升级后的应用程序组中的主应用程序，保证程序运行的完整性，避免程序当前轮次任务未完成，导致系统出错的情况，从而提高系统稳定性。
在一个示例性实施方式中，在将所述升级标志位更新为非升级之后，还包括：将所述第二存储区的区标识由升级存储区更新为运行存储区，并将所述第一存储区的区标识由运行存储区更新为升级存储区；所述程序升级方法，还包括：如果确定所述升级标志位为非升级，则运行位于区标识为运行存储区的应用程序组中主应用程序。
区标识用于标识位于其中的应用程序组是否待运行。区标识为运行存储区，表明位于该存储区中的应用程序组为当前运行的应用程序组。区标识为升级存储区，表明位于该存储区中的应用程序组为待升级的应用程序组，也即该存储区为待更新的存储区。
升级标志位的判断通常是在运行应用程序组之前。在运行应用程序组之前，判断升级标志位，如果升级标志位为升级，则表明当前时刻处于应用程序组升级并运行的过程中，如果升级标志位为非升级，则表明当前时刻处于上电过程中。示例性的，升级标志位为字符串，例如，0x5555AAAA为升级，0为非升级。
在上电过程中，对所有外设模块进行初始化，运行区标识为运行存储区上的应用程序组。
如图4-图5所示，运行存储区运行应用程序，并通过引导加载程序对升级存储区中的待更新功能单元区进行擦除和写入。示例性的，如图4-图5所示，待更新功能单元区为分区2(存储主应用程序)和分区4(存储应用程序1)。在升级存储区中的待更新功能单元区更新完毕后，也即应用程序组升级完毕后，将运行存储区和升级存储区进行互换，图4所示的运行存储区变为图5所示的升级存储区，图4 所示的升级存储区变为图5所示的运行存储区。再通过引导加载程序将运行存储区中的更新后的待更新功能单元区中存储数据同步到变换后的升级存储区中，从而升级后的运行存储区和升级存储区的数据仍然保持一致。
通过配置区标识，区分运行存储区和升级存储区，而且在程序升级后进行同步，保证运行存储区和升级存储区中的数据始终一致，而且在运行应用程序组之前判断升级标志位，并在升级标志位为非升级时，确定处于设备上电过程中，可以直接从默认的引导地址运行运行储存区中的应用程序组，减少易失性数据存储和读取，提高应用程序组运行效率，并根据接收到的升级包更新升级存储区中的应用程序组，实现准确区分上电过程的应用程序组运行过程和工作过程的升级后的应用程序组运行过程，从保证设备正常上电以及正常工作。
在一个示例性实施方式中，电子设备可以包括至少一个处理器，例如，单处理器或者双处理器，应用程序组中主应用程序均加载在内存中运行，而非主应用程序可以加载在内存中运行，也可以在Flash中运行。如图6-图9所示，图6为单处理器，且非主应用程序和引导加载程序在Flash中运行；图7为双处理器，且非主应用程序和引导加载程序在Flash中运行；图8为单处理器，且非主应用程序和引导加载程序在内存中运行；图9为双处理器，且非主应用程序和引导加载程序在Flash中运行。其中，非主应用程序存储区和主应用程序存储区构成应用程序组存储区。
在一个示例性实施方式中，所述程序升级方法应用的电子设备包括一个处理器，所述运行更新后的第二主应用程序，包括：关闭中断；将所述更新后的第二主应用程序加载在内存中，并运行；打开中断。
可以理解的是，在由第一应用程序切换到更新后的第二应用程序运行时，如果存在中断，则会导致CPU自动暂时停止当前运行的第一主应用程序的执行转而执行处理更新后的第二主应用程序，当第二主应用程序覆盖第一主应用程序拷贝在内存并运行时，CPU会返回断点继续执行第一主应用程序。实际上，而此时第一主应用程序已经被覆盖掉，无法正常运行，导致系统运行存在问题。所以为了避免发生中断而产生不可预知的错误，需要预先关闭中断，保证第二主应用程序完整运行。
打开或关闭中断可以通过中断控制指令实现。
通过在切换运行更新后的第二主应用程序之前关闭中断，并在运行更新后的第二主应用程序之后打开中断，保证CPU切换到更新后的第二主应用程序持续运行，避免暂时切换的情况，从而实现准确运行更新后的第二主应用程序。
在一个示例性实施方式中，所述程序升级方法应用的电子设备包括至少两个处理器，所述运行更新后的第二主应用程序，包括：将所述更新后的第二主应用程序加载在第一处理器对应的内存区域中，并运行；关闭中断；将所述第一处理器运行所述更新后的第二主应用程序的运行结果，替换第二处理器运行所述第二主应用程序的运行结果，作为目标运行结果，所述第一处理器与所述第二处理器不同；打开中断；将所述更新后的第二主应用程序加载在除所述第一处理器之外的至少一个处理器分别对应的内存区域中，并运行。
其中，至少两个处理器并行运行主应用程序组，在运行过程中，各处理器共享扩展核心参数和当前核心参数。可以选择任意一个处理器的运行结果作为目标运行结果，进行后续处理。可以通过输出选择单元选择和切换一个处理器的运行结果作为目标运行结果。同时，每个处理对应一个内存区域，不同处理器对应的内存区域不同。示例性的，若处理器的数量为两个，两个处理器可以包括至少两个CPU或者一个CPU和控制律加速器(Control Law Accelerator，CLA)。
第二处理器为目标运行结果的来源处理器，即第二处理器运行主应用程序的运行结果作为目标运行结果。而第一处理为除第二处理器之外的任意一个处理器。
在至少两个处理器开始运行更新后的第二主应用程序时，先选择除目标运行结果的来源处理器之外的任意一个处理器，将更新后的第二主应用程序加载在匹配的内存区域中，并运行。同时关闭中断，选择该处理器的运行结果作为目标运行结果，再开中断。之后将更新后的第二主应用程序分别加载在除第一处理器之外的处理器对应的内存区域中，并运行，从而实现全部处理器对应的内存区域中均加载更新后的第二主应用程序，并运行，保证各个处理器均运行升级后的应用程序组。其中，此时中断开关用于保证在运行结果来源处理器切换时正确切换，避免暂时切换导致返回断点前的运行结果来源。
通过对多个处理器对应的内存区域同步更新后的第二主应用程序，保证运行的均为最新的主应用程序，有助于保持系统稳定工作，同时，直接在内存区域中进行同步，提高升级后的应用程序组的运行效率，提高在线升级的效率。
在一个示例性实施方式中，所述电子设备包括至少两个处理器，在所述第二存储区中对各所述待更新功能单元区中数据进行擦除之前，还包括：如果第二主应用程序为待升级应用程序，则将第二处理器运行第一主应用程序的运行结果，替换第一处理器运行第一主应用程序的运行结果，作为目标运行结果。
实际上，在未根据升级包进行升级之前，可以将第一处理器运行第一主应用程序的运行结果，作为目标运行结果，并在确定第一主应用程序需要升级时，切换至将第二处理器运行第一主应用程序的运行结果作为目标运行结果。从而在第一处理器运行第二主应用程序时，切换到将第一处理器运行第二主应用程序作为目标运行结果，实现多处理器并行运行主应用程序，在线升级，以及目标运行结果的正确切换。
在一个示例性实施方式中，在判断所述第二应用程序组中的第二主应用程序是否为待升级应用程序之前，还包括：如果外设初始化程序为待升级应用程序，则运行升级后的外设初始化程序，所述外设初始化程序用于在主应用程序运行之前，对外设模块进行初始化。
其中，外设初始化程序用于对外设模块进行初始化。外设模块是指电源设备(如电源芯片)内部用于与外部设备连接的接口电路和总线等。
如果外设初始化程序不是待升级应用程序，则直接运行第二主应用程序。
通过在外设初始化程序升级时，运行升级后的外设初始化程序，对外设模块的数据更新，从而保证第二主应用程序在更新后的外设模块的数据下正常运行。
在一个示例中，如图10所示电子设备为电源设备，包括2级，具体为电源设备前级PFC(Power Factor Correction，功率因数校正)，电源设备后级DC(Direct Current，直流)。实际上，电源设备后级DC为直流电路，而电源设备前级PFC为交流电路。电源设备的每级均可以独立实现本申请实施例提供的任一项所述的程序升级方法。电源设备的每级均包括通讯单元、输出选择单元、主应用运行单元和共享内存单元等。
其中，升级交互单元为电源设备以外的独立设备，例如可以是通信系统中的主控制系统，用于监控电源设备是否正常运行等。升级交互单元获取升级包以及该电源设备的升级前文件，其中，升级前的文件中包括第一存储区和第二存储区中存储的数据。升级交互单元根据升级包以及升级前文件，确定待更新功能单元区，并和升级包一起发送至通讯单元中。电源设备的每级都具备通讯单元，用于相互通信，以及分别和升级交互单元通信，接收升级交互单元发送的待更新功能单元区的信息和升级包；或者还可以其中一级和升级交互单元通信，另外一级通过通讯单元获取升级交互单元接收到的信息，例如，电源设备后级DC和升级交互单元交互，电源设备前级PFC的升级数据(包括升级包和待更新功能单元区的信息等)通过与电源设备后级DC进行通信，以接收电源设备后级DC从升级交互单元获取的升级数据。
电源设备的每级均包括一个或两个处理器，输出选择单元用于在存在至少两个处理器时选择主应用程序的目标运行结果的来源处理器，即将哪个处理器运行哪个主应用程序的运行结果作为目标运行结果。
需要说明的是，电源设备中的同级中的不同存储区存储的数据相同，不同级中的存储区存储的数据不同，也即电源设备中的同级中的不同处理器运行的应用程序组相同，不同级中的不同处理器运行的应用程序组中非主应用程序可以不同也可以相同，但主应用程序不同。
主应用程序运行单元用于运行主应用程序，每个处理器对应一个主应用程序运行单元，不同处理器对应不同主应用程序运行单元。
电源设备的同级中的两个处理器彼此之间通过共享内存单元实现核心参数的共享，以及实现升级后主应用程序切换时的数据平滑过渡，保证了电源模块在切换过程中的输出稳定。
输出选择单元根据目标运行结果进行处理，并向电信主设备提供电源输出。
相应的，如图11-图12所示，程序升级方法，应用在电源设备DC级中，可以包括：
S201，升级交互单元接收升级前文件和升级包。

S212，电源设备判断校验是否通过，如果是，则执行S213；否则，执行S214。
