Description

调频方法和相关设备
本申请要求于2021年12月30日提交中国国家知识产权局、申请号为202111658322.1、发明名称为“调频方法和相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及芯片技术领域，尤其涉及一种调频方法和相关设备
背景技术
当前有些厂商为了节约芯片生产成本，在制作两个及以上个频率可调模块时，会采用共用电压的方式。在采用共用电压的场景中，若其中一个频率可调模块的频率变化引起共用的电压升高，而共用的电压升高并未使得其他频率可调模块的频率发生调整或频率调整不及时，致使其他频率可调模块出现电压浪费或者不能满足负载的情况，从而其他频率可调模块存在能效较低、性能不足等问题。
比如，在中国台湾联发科技股份有限公司(MediaTek.Inc，MTK)的芯片中，小核中央处理器(Central Processing Unit，CPU)和三级缓存(level 3 cache，简写为l3 cache)共用电压；当大核CPU工作负载过高时，可能会升高三级缓存的频率，进而可能引起共用的电压升高，而小核CPU未能及时升高频率、继续在低频率下工作，致使小核CPU出现浪费高电压或者不能满足负载的情况，从而小核CPU存在能效较低、性能不足等问题。
发明内容
本申请提供一种调频方法和相关设备，共用电压的频率可调模块的频率可以联动调整，确保能效较高、性能充足。
根据第一方面，本申请涉及一种调频方法，应用于电子设备，所述电子设备包括第一频率可调模块和第二频率可调模块；所述方法包括：若所述第一频率可调模块的频率升高导致所述第一频率可调模块和所述第二频率可调模块共用的电压升高，则获取所述第二频率可调模块在第一公共电压下的第一目标频率，所述第一公共电压为所述第一频率可调模块的频率升高后所述第一频率可调模块和所述第二频率可调模块共用的电压；根据所述第二频率可调模块的负载确定是否将所述第二频率可调模块的频率升高为所述第一目标频率。其中，第一目标频率可以为第二频率可调模块在第一公共电压下的任意频率，优选为第二频率可调模块在第一公共电压下的最小频率。
在本申请实施例中，电子设备中的第一频率可调模块和第二频率可调模块共用电压，当第一频率可调模块的频率升高导致共用的电压升高时，获取第二频率可调模块在升高后的共用的电压下的第一目标频率，然后根据第二频率可调模块的负载确定是否将第二频率可调模块的频率升高为第一目标频率。如此，共用电压的第一频率可调模块和第二频率可调模块的频率可以联动调整，也即第一频率可调模块的频率升高导致共用的电压升高时，第二频率可调模块的频率也可以及时升高，避免第二频率可调模块出现电压浪费或者不能满足负载的情况，从而确保能效较高、性能充足。并且，第一频率可调模块和第二频率可调模块的频率联动调整还是按需进行调整，也即第一频率可调模块的频率升高时，根据第二频率可调模块的负载来确定是否联动第二频率可调模块的频率升高；例如，若第二频率可调模块不需要升高 频率即可满足负载，则不升高第二频率可调模块的频率；若第二频率可调模块需要升高频率才可满足负载，则升高第二频率可调模块的频率；从而做到非必要不升高第二频率可调模块的频率，降低频繁调频带来的额外开销。
在一种可能的实现方式中，所述根据所述第二频率可调模块的负载确定是否将所述第二频率可调模块的频率升高为所述第一目标频率，包括：若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载不大于第一预设阈值，则不将所述第二频率可调模块的频率升高为所述第一目标频率；若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载大于所述第一预设阈值且不大于第二预设阈值，则根据所述第二频率可调模块的能效或所述电子设备的能效确定是否将所述第二频率可调模块的频率升高为所述第一目标频率；若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载大于所述第二预设阈值，则将所述第二频率可调模块的频率升高为所述第一目标频率。
在本实现方式中，当第一频率可调模块的频率升高，导致第一频率可调模块和第二频率可调模块共用的电压升高后，如果第二频率可调模块的负载不大于第一预设阈值，说明第二频率可调模块的负载较低，没有必要升高第二频率可调模块的频率即可满足负载要求，则不将第二频率可调模块的频率升高为第一目标频率；从而非必要不升高第二频率可调模块的频率，降低频繁调频带来的额外开销。如果第二频率可调模块的负载大于第二预设阈值，说明第二频率可调模块的负载较高，需要升高第二频率可调模块的频率才可满足负载要求，则将第二频率可调模块的频率升高为第一目标频率；从而做到及时升高第二频率可调模块的频率，避免电压浪费以及不能满足负载。如果第二频率可调模块的负载大于第一预设阈值且不大于第二预设阈值，说明第二频率可调模块的负载不是太低，也不是太高，第二频率可调模块的频率处于可以升高，也可以不升高的情况下，则根据第二频率可调模块的能效或所述电子设备的能效确定是否将第二频率可调模块的频率升高为第一目标频率；从而避免第二频率可调模块的频率升高后，第二频率可调模块的能效或电子设备的能效降低太多。
在一种可能的实现方式中，所述根据所述第二频率可调模块的能效或所述电子设备的能效确定是否将所述第二频率可调模块的频率升高为所述第一目标频率，包括：若将所述第二频率可调模块的频率升高为所述第一目标频率，所述第二频率可调模块的能效或所述电子设备的能效降低第三预设阈值，则不将所述第二频率可调模块的频率升高为所述第一目标频率；否则，将所述第二频率可调模块的频率升高为所述第一目标频率。
在本实现方式中，如果将第二频率可调模块的频率升高为第一目标频率，第二频率可调模块的能效或所述电子设备的能效降低第三预设阈值，说明升高第二频率可调模块的频率，第二频率可调模块的能效或电子设备的能效会降低太多，则不将第二频率可调模块的频率升高为第一目标频率，从而可以确保第二频率可调模块的能效或电子设备的能效较高，性能也是足够的；否则，说明将升高第二频率可调模块的频率，第二频率可调模块的能效或电子设备的能效不会降低太多，则将第二频率可调模块的频率升高为第一目标频率，从而可以确保第二频率可调模块的性能充足，第二频率可调模块的能效或电子设备的能效也较高。
在一种可能的实现方式中，所述方法还包括：在监测所述第一频率可调模块的频率升高的情况下，获取频率升高后的所述第一频率可调模块的频率；若所述频率升高后的所述第一频率可调模块的频率大于第二目标频率，则确定所述第一频率可调模块的频率升高导致所述第一频率可调模块和所述第二频率可调模块共用的电压升高，所述第二目标频率为所述第一频率可调模块在第二公共电压下的最大频率，所述第二公共电压为所述第一频率可调模块的 频率升高前所述第一频率可调模块和所述第二频率可调模块共用的电压。
在本实现方式中，在监测第一频率可调模块的频率升高的情况下，获取升高后的第一频率可调模块的频率；如果升高后的第一频率可调模块的频率大于第一频率可调模块在升高前的共用的电压下的最大频率，说明第一频率可调模块的频率升高会导致第一频率可调模块和第二频率可调模块共用的电压升高。如此，能够及时监测到第一频率可调模块的频率升高，并及时发现第一频率可调模块和第二频率可调模块共用的电压升高，缩短升高后的共用的电压浪费时长，降低获取第二频率可调模块对应的第一目标频率的时间。

具体实施方式
首先，对本申请实施例中的一些技术术语进行介绍，以便于本领域技术人员理解本申请。
(1)能效：是指为终端用户提供服务理论上发挥作用的能量与实际消耗的总能源量之比，也称为能效比。
(2)能效比曲线：一般由芯片厂商提供或者通过实验室可测得，可以反映出频率、电压和能效比之间的关系。
(3)三级缓存(level 3 cache，简写为l3 cache)：中央处理器(Central Processing Unit，CPU)读取数据过程为：先从缓存文件中查找，在缓存文件中找到之后会自动读取，再输入到CPU进行处理；当然如果没有在缓存中找到对应的缓存文件的话，那么就会从内存中读取并传输给CPU处理。三级缓存是为读取二级缓存后未命中的数据设计的一种缓存，其中，一级缓存内置在CPU内部并与CPU同速运行，以有效提高CPU的运行效率；二级缓存是为了协调一级缓存和内存之间的速度而设计的一种缓存。
(4)负载：是指一段时间内模块运行时间占该段时间的比值。
(5)功耗：是指单位时间中所消耗的能源的数量。
(6)丢帧率：是指一段时间内丢帧数占理论总帧数的比率。
其次，对电子设备中的两个频率可调模块共用电压场景的相关技术进行介绍，以便于本 领域技术人员理解本申请。
(1)相关技术一：有些厂商在面对两个频率可调模块共用电压场景时，设置其中一个频率可调模块的频率是固定值，进而共用的电压被限制不能动态调整。如图1所示，第二频率可调模块的频率固定，从而限制第一频率可调模块与第二频率可调模块的共用的电压限制为最高值。
相关技术一存在以下问题：会导致安装有第一频率可调模块和第二频率可调模块的电子产品的整机功耗升高，从而续航能力变差，影响用户体验。
(2)相关技术二：有些厂商在面对两个频率可调模块共用电压场景时，设置两个频率可调模块的频率都可以单独调整，但是其中一个频率可调模块的频率调整引起共用的电压升高，并不能联动另一频率可调模块的频率调整。如图2所示，第一频率可调模块的频率调整，导致共用的电压升高，但并不会联动第二频率可调模块的频率调整，使得第二频率可调模块存在电压浪费。
相关技术二存在以下问题：两个频率可调模块不能联动的频率调整，存在电压性能不能完全发挥、性能损耗的情况，使得两个频率可调模块的频率无法达到能效最优对应的组合。
(3)相关技术三：有些厂商在面对两个频率可调模块共用电压场景时，并不关注共用的电压，而是直接按照两个频率可调模块各自的最大频率的同一比例做联动调整。
相关技术三存在以下问题：虽然频率变化是保持同一比例，但是各个频率可调模块之间的频率对应的电压变化并不是同一比例，如图3和图4所示，其中，图3和图4的横坐标均表示频点序号，表示第几组；图3的纵坐标表示频率(单位：MHz)，图4的纵坐标表示电压(单位：uV)；如此，当频率调整时，必然存在无需升高的电压被迫调高，导致功耗增大。有些频率可调模块的频率可能并不需要升高便能满足性能需求，但是在同比例联动时，必然导致该频率可调模块频繁调频，无故的升频必然导致功耗的浪费。
需要说明的是，虽然上述仅介绍了两个频率可调模块共用电压场景的相关技术，但该相关技术同样也适用于频率可调模块为两个以上的共用电压场景。
综合上述相关技术存在的缺点，本申请要解决的技术问题包括：在共用电压的场景下，如何使得充分利用功耗，提升性能。
针对本申请要解决的技术问题，本申请提供以下技术方案：多个频率可调模块共用电压场景中，当其中一个频率可调模块的频率调整导致共用的电压升高时，按需选择是否联动调整其他频率可调模块的频率，以达到充分利用功耗，提升性能，降低丢帧率的目的。
下面结合具体实施方式对本申请提供的技术方案进行详细的介绍。
请参阅图5，图5为第一频率可调模块与第二频率可调模块共用电压的场景示意图，第一频率可调模块与第二频率可调模块的频率都可以单独调整，当其中一个频率可调模块的频率调整引起共用的电压升高时，可以联动另一频率可调模块的频率调整。如图5所示，当第一频率可调模块的频率调整(例如频率升高)，导致第一频率可调模块和第二频率可调模块共用的电压升高时，联动第二频率可调模块的频率升高。并且，在联动第二频率可调模块的频率升高的过程中，并不是按照两个频率可调模块各自的最大频率的同一比例做联动调整的，而是根据第二频率可调模块的负载和第二频率可调模块的能效或电子设备的能效等实际需求，来选择是否联动调整第二频率可调模块的频率。其中，具体的联动调整频率的过程如图6所示。
请参阅图6，图6是示出根据本申请一种实施例的调频方法的过程600的流程图。过程600描述为一系列的步骤或操作，应当理解的是，过程600可以以各种顺序执行和/或同时发生，不限于图6所示的执行顺序。过程600可由电子设备执行，该电子设备包括第一频率可调模块和第二频率可调模块；过程600包括但不限于如下步骤或操作：
步骤601：若所述第一频率可调模块的频率升高导致所述第一频率可调模块和所述第二频率可调模块共用的电压升高，则获取所述第二频率可调模块在第一公共电压下的第一目标频率，所述第一公共电压为所述第一频率可调模块的频率升高后所述第一频率可调模块和所述第二频率可调模块共用的电压。
其中，电子设备可以及时获取共用电压的任意一个频率可调模块的频率变化情况，当某个频率可调模块的频率调整导致共用的电压升高时，电子设备可以获取升高后的共用的电压的大小，从而进一步获取共用电压的其他频率可调模块在升高后的共用的电压下的第一目标频率。可选地，该第一目标频率可以为其他频率可调模块在升高后的共用的电压下的任意频率，优选为其他频率可调模块在升高后的共用的电压下的最小频率。
例如，电子设备中的第一频率可调模块和第二频率可调模块共用同一电压，电子设备可以及时获取第一频率可调模块和第二频率可调模块的频率变化情况，若第一频率可调模块的频率升高，并且导致第一频率可调模块和第二频率可调模块共用的电压升高时，电子设备可以获取到升高后的共用的电压的大小，也即电子设备可以获取到第一公共电压的大小，从而进一步获取第二频率可调模块在第一公共电压下的第一目标频率。可选地，第一目标频率可以为第二频率可调模块在第一公共电压下的任意频率，优选为第二频率可调模块在第一公共电压下的最小频率。
步骤602：根据所述第二频率可调模块的负载确定是否将所述第二频率可调模块的频率升高为所述第一目标频率。
其中，当某个频率可调模块的频率调整导致共用的电压升高时，能被电子设备及时获取到，从而能够联动调整其他频率可调模块的频率；而在调整其他频率可调模块的频率的过程中，能够根据其他频率可调模块的负载来确定是否调整其他频率可调模块的频率。
例如，第一频率可调模块的频率升高，并且导致第一频率可调模块和第二频率可调模块共用的电压升高时，电子设备获取到了第二频率可调模块对应的第一目标频率，从而根据第二频率可调模块的负载来确定是否将第二频率可调模块的频率升高为该第一目标频率。
在本申请实施例中，电子设备中的第一频率可调模块和第二频率可调模块共用电压，当第一频率可调模块的频率升高导致共用的电压升高时，获取第二频率可调模块在升高后的共用的电压下的第一目标频率，然后根据第二频率可调模块的负载确定是否将第二频率可调模块的频率升高为第一目标频率。如此，共用电压的第一频率可调模块和第二频率可调模块的频率可以联动调整，也即第一频率可调模块的频率升高导致共用的电压升高时，第二频率可调模块的频率也可以及时升高，避免第二频率可调模块出现电压浪费或者不能满足负载的情况，从而确保能效较高、性能充足。并且，第一频率可调模块和第二频率可调模块的频率联动调整还是按需进行调整，也即第一频率可调模块的频率升高时，根据第二频率可调模块的负载来确定是否联动第二频率可调模块的频率升高；例如，若第二频率可调模块不需要升高频率即可满足负载，则不升高第二频率可调模块的频率；若第二频率可调模块需要升高频率才可满足负载，则升高第二频率可调模块的频率；从而做到非必要不升高第二频率可调模块的频率，降低频繁调频带来的额外开销。
需要说明的是，电子设备中共用同一电压的模块可能有两个或两个以上，第一频率可调 模块和第二频率可调模块可以为共用该同一电压的任意两个模块。应理解，当共用该同一电压的模块只有两个时，其中一个模块的频率升高导致该同一电压升高，则联动另一模块按需升高频率，故第一频率可调模块为其中频率升高而导致该同一电压升高的模块，第二频率可调模块为被联动按需升高频率的另一模块；当共用该同一电压的模块为两个以上时，其中一个模块的频率升高导致该同一电压升高，则联动其他模块中的每个模块按需升高频率，故第一频率可调模块为其中频率升高而导致该同一电压升高的模块，第二频率可调模块为被联动按需升高频率的其他模块中的任意一个模块。
在一种可能的实现方式中，所述根据所述第二频率可调模块的负载确定是否将所述第二频率可调模块的频率升高为所述第一目标频率，包括：若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载不大于第一预设阈值，则不将所述第二频率可调模块的频率升高为所述第一目标频率；若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载大于所述第一预设阈值且不大于第二预设阈值，则根据所述第二频率可调模块的能效或所述电子设备的能效确定是否将所述第二频率可调模块的频率升高为所述第一目标频率；若所述第一频率可调模块和所述第二频率可调模块共用的电压升高后，所述第二频率可调模块的负载大于所述第二预设阈值，则将所述第二频率可调模块的频率升高为所述第一目标频率。
其中，电子设备在获取到共用电压的其他频率可调模块在升高后的共用的电压下的第一目标频率之后，需要判断该第一目标频率是否可以设置；第一目标频率是否可以设置的判断条件包括负载判定条件和能效判定条件。分别如下描述：
(1)负载判定条件为：其中一个频率可调模块的频率升高，导致共用的电压升高后，如果其他频率可调模块的负载不大于第一预设阈值，则说明其他频率可调模块的负载较低，升高频率对其他频率可调模块的性能几乎无影响，故不需要升高其他频率可调模块的频率，也即其他频率可调模块的频率不用设置为第一目标频率；如果其他频率可调模块的负载大于第二预设阈值，则说明其他频率可调模块的频率不能满足负载，故需要升高其他频率可调模块的频率，也即其他频率可调模块的频率可以设置第一目标频率；如果其他频率可调模块的负载大于第一预设阈值且不大于第二预设阈值，则通过能效判定条件判断。
其中，第一预设阈值和第二预设阈值的大小可以根据频率可调模块的实际应用场景来选择；就第二预设阈值而言，如果需要高性能可以把该第二预设阈值设置的低点，相反可以把该第二预设阈值设置的高点。例如，将第一预设阈值设置为满负载的30％，当频率可调模块的实际工作负载不超过满负载的30％时，即认为该频率可调模块的频率较低，升高频率对该频率可调模块的性能几乎无影响；将第二预设阈值设置为满负载的60％，当频率可调模块的实际工作负载超过满负载的60％时，即认为该频率可调模块的频率不能满足负载。
(2)能效判定条件为：其中一个频率可调模块的频率升高，导致共用的电压升高，且获取到其他频率可调模块在升高后的共用的电压下的第一目标频率，如果将其他频率可调模块的频率设置为该第一目标频率，其他频率可调模块的能效或电子设备的能效降低第三预设阈值，则说明升高其他频率可调模块的频率会使得其他频率可调模块的能效或电子设备的能效降低太多(或劣化严重)，降低程度(或劣化程度)不能接受，故不将其他频率可调模块的频率设置为该第一目标频率；否则，说明升高其他频率可调模块的频率并不会使得其他频率可调模块的能效或电子设备的能效降低太多，降低程度可以接受，故可以将其他频率可调模块的频率设置为该第一目标频率。
其中，第三预设阈值的大小可以根据频率可调模块的实际应用场景或电子设备的的实际 应用场景来选择；如果追求性能，可以将第三预设阈值设置为较大值；如果追求长续航，可以将第三预设阈值设置为较小值。例如，在追求长续航时，将第三预设阈值设置为0。此外，频率可调模块对应的第三预设阈值和电子设备对应的第三预设阈值，可以相同，也可以不同。
其中，能效判定可以基于能效比曲线实现，能效比曲线可以反映出频率、电压和能效之间的关系，如此，当获取到升高后的共用的电压(例如第一公共电压)，以及获取到第一目标频率后，可以基于能效比曲线中频率、电压和能效之间的关系，确定在该升高后的共用的电压(例如第一公共电压)下将其他频率可调模块的频率设置为该第一目标频率后，该其他频率可调模块的能效或电子设备的能效的大小，从而判断出其他频率可调模块的能效或电子设备的能效的降低程度。
在本实现方式中，当第一频率可调模块的频率升高，导致第一频率可调模块和第二频率可调模块共用的电压升高后，如果第二频率可调模块的负载不大于第一预设阈值，说明第二频率可调模块的负载较低，没有必要升高第二频率可调模块的频率即可满足负载要求，则不将第二频率可调模块的频率升高为第一目标频率；从而非必要不升高第二频率可调模块的频率，降低频繁调频带来的额外开销。如果第二频率可调模块的负载大于第二预设阈值，说明第二频率可调模块的负载较高，需要升高第二频率可调模块的频率才可满足负载要求，则将第二频率可调模块的频率升高为第一目标频率；从而做到及时升高第二频率可调模块的频率，避免电压浪费以及不能满足负载。如果第二频率可调模块的负载大于第一预设阈值且不大于第二预设阈值，说明第二频率可调模块的负载不是太低，也不是太高，第二频率可调模块的频率处于可以升高，也可以不升高的情况下，则根据第二频率可调模块的能效或所述电子设备的能效确定是否将第二频率可调模块的频率升高为第一目标频率；从而避免第二频率可调模块的频率升高后，第二频率可调模块的能效或电子设备的能效降低太多。
在一种可能的实现方式中，所述根据所述第二频率可调模块的能效或所述电子设备的能效确定是否将所述第二频率可调模块的频率升高为所述第一目标频率，包括：若将所述第二频率可调模块的频率升高为所述第一目标频率，所述第二频率可调模块的能效或所述电子设备的能效降低第三预设阈值，则不将所述第二频率可调模块的频率升高为所述第一目标频率；否则，将所述第二频率可调模块的频率升高为所述第一目标频率。
具体地，根据能效比曲线判断，如果在第一公共电压下将第二频率可调模块的频率升高为第一目标频率，第二频率可调模块或电子设备的能效为多少，从而判断第二频率可调模块的能效或所述电子设备的能效是否会降低第三预设阈值；如果会降低第三预设阈值，则不将第二频率可调模块的频率升高为第一目标频率；如果不会降低第三预设阈值，则可以将第二频率可调模块的频率升高为第一目标频率。
在本实现方式中，如果将第二频率可调模块的频率升高为第一目标频率，第二频率可调模块的能效或所述电子设备的能效降低第三预设阈值，说明升高第二频率可调模块的频率，第二频率可调模块的能效或电子设备的能效会降低太多，则不将第二频率可调模块的频率升高为第一目标频率，从而可以确保第二频率可调模块的能效或电子设备的能效较高，性能也是足够的；否则，说明将升高第二频率可调模块的频率，第二频率可调模块的能效或电子设备的能效不会降低太多，则将第二频率可调模块的频率升高为第一目标频率，从而可以确保第二频率可调模块的性能充足，第二频率可调模块的能效或电子设备的能效也较高。
在一种可能的实现方式中，所述方法还包括：在监测所述第一频率可调模块的频率升高的情况下，获取频率升高后的所述第一频率可调模块的频率；若所述频率升高后的所述第一频率可调模块的频率大于第二目标频率，则确定所述第一频率可调模块的频率升高导致所述 第一频率可调模块和所述第二频率可调模块共用的电压升高，所述第二目标频率为所述第一频率可调模块在第二公共电压下的最大频率，所述第二公共电压为所述第一频率可调模块的频率升高前所述第一频率可调模块和所述第二频率可调模块共用的电压。
其中，电子设备可以及时获取共用电压的任意一个频率可调模块的频率变化情况，当某个频率可调模块的频率调整时，例如某个频率可调模块的频率升高时，电子设备还可以获取该频率可调模块频率升高后的频率，并判断该升高后的频率是否超过该频率可调模块在当前公共电压下所允许的最大频率；若超过当前公共电压所允许最大频率，则会触发公共电压升高。
例如，电子设备监测到第一频率可调模块的频率升高时，获取第一频率可调模块频率升高后的频率，并判断第一频率可调模块频率升高后的频率是否大于第一频率可调模块频率在第二公共电压下的最大频率；如果大于，则说明第一频率可调模块的频率升高会导致第一频率可调模块和第二频率可调模块共用的电压升高。
在本实现方式中，在监测第一频率可调模块的频率升高的情况下，获取升高后的第一频率可调模块的频率；如果升高后的第一频率可调模块的频率大于第一频率可调模块在升高前的共用的电压下的最大频率，说明第一频率可调模块的频率升高会导致第一频率可调模块和第二频率可调模块共用的电压升高。如此，能够及时监测到第一频率可调模块的频率升高，并及时发现第一频率可调模块和第二频率可调模块共用的电压升高，缩短升高后的共用的电压浪费时长，降低获取第二频率可调模块对应的第一目标频率的时间。
需要说明的是，过程600描述的一系列的步骤或操作，还可以对应参照图5所示实施例的相应描述。
下面通过图7至图11所示的具体示例对图6所示的过程600进一步描述。

其中，应用层则是用户可以直接感知的一些应用程序(Applicatio，APP)等。
其中，内核层位于应用层和芯片层之间，向上可以为应用层提供部署和运行环境，向下可以设置物理硬件类型的芯片层参数，内核层是软件实现的。内核层包括调频装置，调频装置包括调频监听器、负载判定模块、能效判定模块和频率设置模块(图7中未示出)。
其中，芯片层中包括共用电压的模块，例如包括共用电压的第一频率可调模块和第二频率可调模块，第二频率可调模块只是象征性代表与第一频率可调模块共用电压的其中一个模块，实际上可能会存在多个与第一频率可调模块共用电压的模块。
当应用层中第一频率可调模块相应的负载升高或者其他原因导致第一频率可调模块升频时，调频监听器可以及时获取第一频率可调模块将要升频到的频率。在此情况下，调频监听器还可以及时获知第一频率可调模块升频是否导致第一频率可调模块和第二频率可调模块共用的电压升高；若第一频率可调模块升频导致共用的电压升高，也即共用的电压升高为第一公共电压，则调频监听器可以及时获取第二频率可调模块在第一公共电压下的第一目标频率(例如最小频率)。调频监听器获取到第一目标频率后，但是并非一定将第二频率可调模块的频率设置为该第一目标频率，调频装置能够按需确定是否将第二频率可调模块的频率设置为该第一目标频率。具体地，需要负载判定模块根据第二频率可调模块的负载进行判定，以及能效判定模块根据第二频率可调模块的能效或电子设备的能效进行判定，以确定是否将第二频率可调模块的频率设置为该第一目标频率。
其中，负载判定模块判断：第二频率可调模块的频率能否满足负载，以及第二频率可调模块的负载是否低到升高频率对第二频率可调模块的性能几乎无影响。如果负载判定模块判断到第二频率可调模块的频率不能满足负载，则频率设置模块可以直接将第二频率可调模块的频率设置为该第一目标频率；如果负载判定模块判断到第二频率可调模块的负载较低，升高频率对第二频率可调模块的性能几乎无影响，则频率设置模块不将第二频率可调模块的频率设置为该第一目标频率；否则，进一步通过能效判定模块进行判定。
其中，能效判定模块根据能效比曲线判断：如果将第二频率可调模块的频率设置为第一目标频率后，是否会导致第二频率可调模块的能效劣化严重或导致电子设备的能效比劣化严重。如果能效判定模块判断到将第二频率可调模块的频率设置为第一目标频率后，导致第二频率可调模块的能效劣化的劣化程度或导致电子设备的能效劣化的劣化程度可以接受，则频率设置模块将第二频率可调模块的频率设置为第一目标频率，也即将第二频率可调模块的频率升高为第一目标频率，进而提升应用层的用户体验；否则，频率设置模块不将第二频率可调模块的频率设置为第一目标频率。
综上描述，图7所示的电子设备设置调频监听器监听各个频率可调模块的频率变化情况，能够及时的获取共用的电压的变化情况，进而计算出共用电压下其他频率可调模块的第一目标频率。相比于不能监听到共用电压的某一频率可调模块的频率升高，且不能判断到共用的电压的变化情况，图7所示的电子设备可以尽早发现共用的电压的变化情况，缩短共用的电压升高后的浪费时长，降低获取其他频率可调模块的第一目标频率的时间。
进一步地，当某一频率可调模块的频率升高导致共用的电压升高后，图7所示的电子设备可以获取其他频率可调模块的负载情况，判断其他频率可调模块的频率是否满足负载，不满足则将其他频率可调模块的频率设置为第一目标频率；否则，再根据能效比曲线判断在升高后的共用的电压下将其他频率可调模块的频率设置为第一目标频率，是否会导致能效劣化严重；若能效劣化程度可以接受，且其他频率可调模块的负载处于一个较高但其频率满足负载的位置时，则可以将其他频率可调模块的频率设置为第一目标频率；否则，不将其他频率可调模块的频率设置为第一目标频率。相比于在获取到第一目标频率后，直接将其他频率可调模块的频率设置为第一目标频率，图7所示的电子设备能够有效按需调整其他频率可调模块的频率；一方面做到非必要不设置，降低频繁调频带来的额外开销；另一方面做到能效劣化可接受则设置，不会出现能效劣化严重而功耗异常增大的情况。

需要说明的是，图8所描述的步骤或操作可以对应参照图7所示的实施例的描述。
请参阅图9，图9为本申请实施例提供的另一种电子设备的组件架构示意图；该电子设备可以为图6所示的实施例中的电子设备，该电子设备包括应用层、内核层和芯片层；其中，图9所示的电子设备的应用层和内核层分别与图7所示的电子设备的应用层和内核层相同，可直接参照图7所示的描述，此处不再重复描述。
其中，图9所示的电子设备的芯片层为MTK的天玑1000芯片，该电子设备可以为使用MTK的天玑1000芯片的手机；在天玑1000芯片中，三级缓存和小核CPU共用电压，也即三级缓存对应上述第一频率可调模块，小核CPU对应上述第二频率可调模块。当应用层启动的进程较多导致负载增加时，天玑1000芯片中的大核CPU的频率增加，从而伴随着数据流的增加，为了满足高数据流的需求，三级缓存的频率也会被升高。三级缓存的频率升高可能会导致三级缓存和小核CPU共用的电压升高。为了高效使用升高后的共用的电压，提升整机性能和用户体验，电子设备会执行以下步骤或操作：
(1)设置调频监听器。
设置调频监听器的主要目的在于：监听三级缓存的频率变化情况，当三级缓存的频率需要升高时，能够被调频监听器及时获取；进而根据三级缓存将要升高到的频率判断是否会引起三级缓存与小核CPU共用的电压升高，如果会引起三级缓存与小核CPU共用的电压升高，则获取小核CPU在升高后的共用的电压下的第一目标频率(例如最小频率)；否则，调频监听器继续监听下一次三级缓存的升频情况。
请参阅图10，图10为图9所示的电子设备执行的一种频率获取方法的流程示意图；该频率获取方法包括但不限于如下步骤或操作：
步骤1001：设置调频监听器。
步骤1002：系统正常工作。
步骤1003：监听到三级缓存将要升频。
其中，电子设备可以通过调频监听器监听到三级缓存将要升频。
步骤1004：判断三级缓存升频是否导致三级缓存与小核CPU共用的电压升高。
其中，电子设备可以通过调频监听器判断三级缓存升频是否导致三级缓存与小核CPU共用的电压升高；若三级缓存升频导致三级缓存与小核CPU共用的电压升高，则执行步骤1005；否则，返回执行步骤1002。
步骤1005：获取小核CPU在升高后的共用的电压下的第一目标频率。
其中，电子设备可以通过调频监听器获取第一目标频率(例如最小频率)。
(2)共用的电压升高后，判断是否需要升高小核CPU的频率。
当获取到小核CPU对应的第一目标频率(例如最小频率)后，还需要判断该第一目标频率是否可以设置。判断的条件有两个：一个是小核CPU的负载情况，另一个是根据能效比曲线。
请参阅图11，图11为图9所示的电子设备执行的一种调频方法的流程示意图；该调频方法包括但不限于如下步骤或操作：
步骤1101：判断小核CPU的频率是否满足负载。
其中，电子设备可以通过负载判定模块判断小核CPU的频率是否满足负载；若小核CPU的频率已经无法满足负载，则执行步骤1104；否则，执行步骤1102。
其中，可以设定当小核CPU的负载大于60％时，认为小核CPU的频率无法满足负载。
步骤1102：判断小核CPU的负载是否较低。
其中，电子设备可以通过负载判定模块判断小核CPU的负载是否较低，也即判断小核CPU频率是否低到不需要升高频率；若小核CPU的负载较低，则执行步骤1105；否则，执行步骤1103。
其中，可以设定当小核CPU的负载不大于30％时，认为小核CPU的负载较低。
步骤1103：判断将小核CPU的频率设置为第一目标频率后，能效劣化程度是否可接受。
其中，电子设备可以通过能效判定模块判断将小核CPU的频率设置为第一目标频率后，能效劣化程度是否可接受；若能效劣化程度可接受，则执行步骤1104；否则，执行步骤1105。
其中，可以将能效劣化是否可以接受的程度设置得很保守，例如只要能效劣化大于0，则认为不能接受。
步骤1104：将小核CPU的频率设置为第一目标频率。
其中，电子设备可以通过频率设置模块将小核CPU的频率设置为第一目标频率。
步骤1105：不将小核CPU的频率设置为第一目标频率。
综上所述，现有技术中无法使小核CPU和三级缓存之间根据共用的电压升高来联动调整频率，最多也就达到小核CPU和三级缓存两个模块之间相互独立设置频率，这样就会导致共用的电压升高后发生浪费。而本申请能够及时发现三级缓存的频率升高导致的共用的电压升高情况，进而按需决定是否升高小核CPU频率，从而可以解决电压浪费、提频缓慢的问题，达到快速提频、提升产品整机性能的效果。当本申请的电子设备为手机时，可以降低手机的丢帧率，显著提升用户体验，测试结果表明：手机滑动性能从0.0855％的丢帧率，降低到0.0658％的丢帧率，性能提升20％以上。
