具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
游戏的流畅运行需要电子设备的SOC的及时充分供给,其中，SOC可以包括中央处理器(central processing unit，CPU)、图形处理器(graphics processing unit，GPU)、双倍速率同步动态随机存储器(double data rate，DDR)。在大多数场景下，Android系统当前的SOC调度采用基于负载的调度算法，但是该调度算法的调度周期长、调度策略保守，没有针对游戏场景的资源需求特点进行及时充分的调度，因此采用该调度算法，也会出现帧率波动。在一些特殊场景(例如发热严重)下，SOC的频率被限制，无法保证SOC及时充分供给，如果仍然要求比较高的帧率，这样也会出现帧率大幅波动。
在现有技术方案中，为了保障SOC的及时充分供给，在进入游戏应用之后，将游戏进程迁移到CPU大核，将CPU、GPU、DDR的工作频率锁定在一个比较高的频率。但是，由于每个场景对SOC的需求不同，如果在所有场景下将CPU、GPU、DDR的工作频率都锁定在一个比较高的频率，这样会导致功耗浪费，引起手机发热，仍然会出现帧率大幅波动。同时，这种简单的保障方式无法解决游戏突发高负载时的资源供给，依然会出现帧率陡然下降的情况。此外，温度过高也会导致CPU、GPU、DDR的工作频率受到限制。

下面结合图1所示的电子设备的结构以及图2所示的软件结构框图，对本申请实施例频率调整方法进行详细说明。在一些实施例中，当电子设备检测到游戏启动时，开启频率动态调整的功能，对SOC的工作频率进行调整。在另一些实施例中，电子设备监测到游戏启动后，会弹出提示框，提示用户是否使用频率动态调整的功能。本申请实施例对频率动态调整的功能的启动方式不做限定。
以下通过具体实施例进行介绍。
请参考图3，图3是本申请实施例提供的一种应用于终端的频率调整方法的流程示意图。如图所示，本申请实施例中的步骤至少包括：
S301，监测实际帧率。
启动频率动态调整的功能后，电子设备开始监测电子游戏画面的实际帧率。在一些实施例中，电子设备开始获取游戏场景的实际帧率，通过实际帧率得到每帧图像的实际绘制时长。其中，帧率可以表示每秒绘制图像的帧数。例如，假设当前实际帧率为80fps(每秒传输帧数)，则当前每帧图像的实际绘制时长为1000ms/80＝12.5ms。
S302，确定每帧图像的实际绘制时长是否超过理论绘制时长。
如果每帧图像的实际绘制时长没有超过理论绘制时长，则跳转到S301，继续监测实际帧率。如果每帧图像的实际绘制时长超过理论绘制时长，则执行步骤S303。
其中，理论绘制时长可以由目标帧率计算得到，目标帧率可以为游戏设计的最高帧率。例如，对于最高帧率为60fps的游戏，每帧图像的理论绘制时长为1000ms/60＝16.6ms。
S303，按照预设周期统计多帧图像的绘制时长,判断多帧图像的帧率变化情况是否处于相对稳定状态。
具体实现中，可以循环获取N帧的实际绘制时长(在第1个周期内获取N帧图像的绘制时长，在第2个周期内获取另一N帧图像的绘制时长，……)。其中，N可以为3、4或5等等。然后分别比较多个N帧图像的绘制时长是否相同或者近似相同，如果多个N帧图像的绘制时长相同或者近似相同，则说明多帧图像的帧率变化情况处于相对稳定状态，即帧率没有出现大幅波动，执行步骤S304。如果多个N帧图像的绘制时长之间的差值很大，或者不断递增，则说明多帧图像的帧率变化情况处于不稳定状态，即帧率出现大幅波动。在此情况下，可以进行单帧脉冲调频或帧率控制，具体方法可以参见以下实施例中的详细说明。
例如，可以每隔3帧统计一次，统计多个3帧图像的绘制时长，计算每个3帧图像的绘制时长的平均值，根据每个3帧图像的绘制时长的平均值，计算每个3帧图像的帧率。平均值越大，帧率越小；平均值越小，帧率越大。然后对多个3帧图像的绘制的平均值进行比较，确定帧率是否出现大幅波动。如图4(A)所示，图4(A)是本申请实施例提供 的一种帧率波动的示意图，随着绘制时间的推移，帧率在某些时间点上出现大幅波动，处于不稳定状态。又如图4(B)所示，图4(B)是本申请实施例提供的一种帧率稳定的示意图，随着绘制时间的推移，帧率波动幅度较小，处于相对稳定状态。
需要说明的是，在执行S301之后，可以直接执行S303，通过统计多帧图像的实际绘制时长，确定多帧图像的帧率变化情况。
S304，获取SOC的当前温度或SOC的当前负载。或者，获取SOC的当前温度以及SOC的当前负载。
具体实现中，可以将SOC运行时一段时间内的平均温度作为GPU的当前温度。可以获取当前SOC的所处理的任务数量，然后将该任务数量除以SOC能够处理的最大任务数，计算得到SOC的当前负载。
S305，根据当前温度和当前负载，确定是否存在提升帧率的可能性。
具体实现中，如果当前温度超过第一预设阈值或者SOC的当前负载超过第二预设阈值，则确定不存在提升帧率的可能性，跳转到S301，继续监测帧率。如果当前温度没有超过第一预设阈值或者SOC的当前负载没有超过第二预设阈值，则确定存在提升帧率的可能性。或者，当前温度没有超过第一预设阈值以及SOC的当前负载没有超过第二预设阈值，则确定存在提升帧率的可能性。若存在提升帧率的可能性，则执行S306。其中，第一预设阈值可以为保持帧率稳定时SOC的最高温度，例如第一预设阈值可以为40摄氏度或39摄氏度，第二预设阈值为SOC的最大负载数量，例如第二预设阈值可以为70％或80％。
S306，在保障帧率稳定的前提下，提升SOC的工作频率，以便增加SOC的及时供给。
具体实现中，可以将SOC的工作频率锁定到一个较高的稳态(例如理论最高频率)，持续一段时间后恢复为调整前的工作频率。其中，该一段时间可以为4ms，也可以是理论绘制时长，例如，对于最高帧率为60fps的游戏，该理论绘制时长可以为16.6ms。在完成调整工作频率之后，跳转到S302，确定下一帧图像的实际绘制时长是否超过理论绘制时长。
在本申请实施例中，在帧率稳定的情况下，可以根据当前温度或者当前负载，确定是否存在提升帧率的可能性。如果存在提升帧率的可能性，则在保障帧率稳定的前提下，提升SOC的工作频率，以便增加SOC的及时供给，提升帧率到一个相对较高的稳定状态。
请参考图5，图5是本申请实施例提供的另一种应用于终端的频率调整方法的流程示意图。如图所示，本申请实施例中的步骤至少包括：
S501，监测实际帧率。
具体实现中，可以监测当前实际帧率，根据实际帧率计算M帧图像中每帧图像的实际绘制时长，其中，所述M为大于等于1的整数。帧率可以表示每秒绘制图像的帧数。例如，假设当前实际帧率为80fps(每秒传输帧数)，则每帧图像的实际绘制时长为1000ms/80＝12.5ms。
S502，确定每帧图像的实际绘制时长是否超过理论绘制时长。如果未超过，则跳转到S501，继续监测实际帧率。如果超过，则执行S503。
其中，理论绘制时长可以由目标帧率计算得到，该目标帧率可以为游戏设计的最高帧率。例如，对于60fps的游戏，每帧图像的理论绘制时长为1000ms/60＝16.6ms。
S503，确定SOC的当前温度是否超过第一预设阈值。若当前温度超过第一预设阈值，则执行S504，若当前温度没有超过第一预设阈值，则执行S505。其中，第一预设阈值可以为保持帧率稳定时SOC的最高温度，例如第一预设阈值可以为40摄氏度或39摄氏度。
应理解，在SOC供给较高或温度较高情况下，如果继续采用较高的帧率绘制图像，温度会持续上升，引发SOC的工作频率被限制，导致帧率大幅波动。例如，CPU的最大主频是2.6GHz，当前CPU主频已经到达2.6GHz，此时已经没有提供资源供给的空间。或者，当前温度已经超过39摄氏度，如果继续提升CPU的主频，会导致CPU耗电增大，温度快速上升，引起帧率大幅波动。
S504，降低SOC的工作频率或者当前负载。
具体实现中，可以通过控制所述每帧图像的实际绘制时长，降低所述SOC的工作频率。进一步的，可以确定所述多帧图像中K帧图像的实际绘制时长的中间值；然后将每帧图像的实际绘制时长调整到所述中间值。或者，可以按照预设的档位时长增加所述每帧图像的实际绘制时长。其中，K可以为3、4或5等等。
例如，在SOC的温度较高时，可以统计3帧图像的实际绘制时长，计算出该3帧图像的实际绘制时长的中间值，然后在接下来的游戏应用与系统接口交互过程中进行帧率控制。如果某帧图像的实际绘制时长小于该中间值，则将该帧图像的实际绘制时长调整到中间值，从而降低帧率。如果某帧图像的实际绘制时长不小于该中间值，由于当前温度较高或当前负载较高，可以维持该实际绘制时长，对该帧图像的实际绘制时长不进行调整。在经过上述调整后，再次统计3帧图像的实际绘制时长，如果帧率仍然不够稳定，可以按照1ms的档位时长增加每帧图像的实际绘制时长，继续降低帧率，控制温度上升直到帧率达到稳定。其中，帧率可以设置最低值。例如在对每秒60帧的游戏进行帧率控制时，帧率的最低值可以设置为每秒45帧，调整后的帧率不能低于45帧。
又如，可以通过以下方式进行帧率控制：游戏应用在绘制每帧图像时需要调用系统接口，系统接口绘制完成图像之后会通知游戏应用，游戏应用接收到通知后，再进行下一帧图像的绘制。因此，可以在这个系统接口处插入代码，系统接口绘制完成图像之后延迟通知游戏应用，例如在某一帧图像绘制完成后，系统接口延迟1ms通知游戏应用，相当于按照1ms的档位时长增加每帧图像的绘制时长，这样每帧图像的实际绘制时长调整到16.6ms+1ms。
如图6(A)所示，上部分曲线为温度变化曲线，下部分曲线为帧率变化曲线。随着温度的升高，帧率开始大幅波动。在图6(A)所示的帧率波动情况下，平均帧率为51.89，帧率方差为6.36，GPU平均温度为52.92，CPU平均温度为53.84，电池平均温度为39.45，帧数比值为32.49％，波动率为5.84。其中，帧率方差可以表示每帧图像的实际绘制时长之间的方差，帧数比值可以表示每秒钟内帧率小于45的帧数所占每秒绘制总帧数的比值，波动率可以根据帧率的波动情况确定。又如图6(B)所示，上部分曲线为温度变化曲线，下部分曲线为帧率变化曲线。在图6(B)所示的帧率稳定情况下，平均帧率为48.38，帧率方差为1.37，GPU平均温度为49.47，CPU平均温度为51.06，电池平均温度为37.04， 帧数比值为2.75％，波动率为1.81。可以看出，在控制平均帧率从51.89fps降低到48.38fps时，GPU、CPU以及电池的温度全部下降，帧率方差、帧数比值和波动率也都相应下降，此时帧率处于相对稳定状态。
S505，提升SOC的工作频率。
具体实现中，可以通过单帧脉冲调频将SOC的所述工作频率调整为预设的最高频率。例如，可以将SOC的工作频率锁定为理论最高频率，持续一段时间后恢复为调整前的工作频率，其中，该一段时间可以为4ms，也可以是理论绘制时长，例如，对于最高帧率为60fps的游戏，该理论绘制时长为16.6ms。
在一种可选的方式中，可以在每帧图像绘制过程中，判断每帧图像的实际绘制时长是否超过理想的绘制时长，如果超过，则开始单帧脉冲调频，并在单帧图像绘制完成时，结束单帧脉冲调频，然后进行下一帧图像的绘制。
例如，假设每帧图像的理论绘制时长(也可以称为刷新屏幕周期)为16.6ms，如果每帧图像的实际绘制时长超过16.6ms，则图像绘制的速度赶不上屏幕刷新的速度，因此无法绘制完成图像并提供给屏幕显示，因而导致丢帧。在此过程中，为了避免丢帧，可以在每帧图像绘制到15ms还未结束时，获取当前CPU和DDR的当前负载，如果CPU或DDR的当前负载大于80％，可以进行单帧脉冲调频。
如图7所示，图7是本申请实施例提供的一种单帧脉冲调频的示意图。第一行为屏幕刷新的时间进度条，假设每帧图像的理论绘制时长为16.6ms，电子设备按照16.6ms周期进行屏幕刷新。第二行为图像绘制的时间进度条，从第二行的第1段时间看出，绘制完成单帧图像需要的实际绘制时长是20ms，已经超过刷新屏幕周期16.6ms，因此在单帧图像绘制到15ms时，判断单帧图像是否绘制完成，如果没有绘制完成，则在单帧图像的绘制到15ms(最理想的绘制时长)时，进行单帧脉冲调频，提高帧率，缩短单帧图像的绘制时长。从第二行的第2段时间看出，绘制完成单帧图像需要的实际绘制时长是16.6ms，该实际绘制时长等于刷新屏幕周期，可以不进行单帧脉冲调频。从第二行的第3段时间看出，绘制完成单帧图像需要的实际绘制时长是20ms，已经超过刷新屏幕周期16.6ms，因此在单帧图像绘制到15ms时，判断单帧图像是否绘制完成，如果没有绘制完成，则在单帧图像的绘制到15ms(最理想的绘制时长)时，进行单帧脉冲调频，提高帧率，缩短单帧图像的绘制时长。从第二行的第4段时间和第5段时间看出，绘制完成单帧图像需要的实际绘制时长都是15ms，均小于刷新屏幕周期16.6ms，因此不需要进行单帧脉冲调频。对于接下来各帧图像，如果实际绘制时长超过理论绘制时长，都可以按照上述方法进行单帧脉冲调频。
在另一种可选的方式中，电子设备连续绘制多帧图像(第1帧、第2帧、第3帧、第4帧、……)，如果确定第1帧图像的实际绘制时长超过理论绘制时长，则在第2帧图像绘制到理论绘制时长时，开始单帧脉冲调频，并在第2帧图像绘制完成时，结束单帧脉冲调频，然后确定第3帧图像的实际绘制时长是否超过理论绘制时长，如果超过，则在第4帧图像绘制到理论绘制时长时，开始单帧脉冲调频，并在第4帧图像绘制完成时，结束单帧脉冲调频，以此类推。
S506，确定每帧图像的实际绘制时长是否缩短到合理水平。若是，则说明每帧图像 的实际绘制时长没有超过理论绘制时长，跳转到S501，继续监测实际帧率。若否，则执行S507。
具体实现中，可以在提升SOC的工作频率之后，确定每帧图像的实际绘制时长是否位于合理区间。例如，假设理论绘制时长为16.6ms，在提升SOC的工作频率之前，每帧图像的实际绘制时长是20ms，在提升SOC的工作频率之后，每帧图像的实际绘制时长缩短到15ms，由于实际绘制时长15ms位于合理区间、且为最理想的绘制时长，因此可以确定每帧图像的实际绘制时长已经缩短到合理水平。
S507，执行确定突发资源高需求流程。具体方式可以参考如下实施例。
在本申请实施例中，在帧率出现大幅波动的情况下，结合当前温度和实际绘制时长，调整SOC的工作频率，以便控制帧率的稳定。
请参考图8，图8是本申请实施例提供的又一种应用于终端的频率调整方法的流程示意图。如图所示，本申请实施例中的步骤至少包括：
S801，监测实际帧率。具体实现方式可以参考S301，本步骤不再赘述。
S802，确定每帧图像的实际绘制时长是否超过理论绘制时长。如果没有超过，则跳转到S801，继续监测实际帧率。如果超过，则执行S803。
S803，按照预设周期统计多帧图像的实际绘制时长，确定多帧图像的帧率变化情况是否处于相对稳定状态。若是，则跳转到S802，执行S802的步骤。若否，则执行S804。具体实现方式可以参考S303，本步骤不再赘述。
S804，获取SOC的的当前温度。
S805，确定当前温度是否超过第一预设阈值。若超过，执行S806。若没有超过，则执行S807。其中，第一预设阈值可以为,保持帧率稳定时SOC的最高温度，例如第一预设阈值可以为40摄氏度或39摄氏度。
S806，降低SOC的工作频率或者当前负载。具体实现方式可以参考S504，本步骤不再赘述。若执行完毕，则可以跳转到S802，继续执行S802的步骤。
S807，获取SOC的当前负载。
具体实现中，可以获取当前SOC的所处理的任务数量，然后将该任务数量除以SOC能够处理的最大任务数，计算得到SOC的当前负载。
S808，确定多帧图像的实际绘制时长的变化趋势。
具体实现中，可以统计所述多帧图像中每N帧图像的实际绘制时长之和，所述N为大于等于1的整数；然后根据多个所述N帧图像的所述绘制时长之和，确定所述绘制时长之和的增长量；最后根据所述绘制时长之和的增长量，确定所述多帧图像的所述实际绘制时长的所述变化趋势。例如，可以每隔5帧图像统计一次，每次统计5帧图像的实际绘制时长，确定多个5帧图像的实际绘制时长的变化情况。
S809，根据SOC的当前负载以及多个N帧图像的实际绘制时长的变化趋势，确定是否为突发资源高需求。如果是，则执行S810，如果否，则跳转到S803。
具体实现中，可以确定SOC的当前负载是否超过第二预设阈值、每个N帧图像的实际绘制时长减去理论绘制时长的差值是否大于第三预设阈值、且多个N帧图像的实际绘制时长之间的增长量是否大于第四预设阈值，确定是否为突发资源高需求。其中，第二预 设阈值可以SOC的最大负载数量，例如第二预设阈值70％或80％，第三预设阈值可以为理论绘制时长16.6ms，第四预设阈值也可以为理论绘制时长16.6ms等等。以上各个参数均可以根据具体场景进行设置。如果SOC的当前负载超过第二预设阈值、每个N帧图像的实际绘制时长减去理论绘制时长的差值大于第三预设阈值、且多个N帧图像的实际绘制时长之间的增长量大于第四预设阈值，则确定为突发资源高需求。
例如，假设每帧图像的理论绘制时长为16.6ms。实时监控5帧图像的实际绘制时长，将该5帧图像的实际绘制时长与5帧图像的理论绘制时长进行比较，如果5帧图像的实际总绘制时长减去5帧图像的理论绘制时长的差值大于16.6ms，可以确定为资源高需求。同时，可以将监控到的5帧图像的实际绘制时长与之前监测到的5帧图像的实际绘制时长进行对比，如果该5帧图像的实际绘制时长大于之前监测到的5帧图像的实际绘制时长，且二者之间的增长值大于16.6ms，并且SOC的当前负载大于80％，则确定为突发资源高需求。
S810，提升SOC的工作频率，提供短时高资源供给。在执行完成后，跳转到S803，执行S803的步骤。
具体实现中，SOC可以包括CPU、DDR和GPU，每个调频组合包括CPU对应的频率、DDR对应的频率以及GPU对应的频率。可以预先按照不同的档位设置多个调频组合，并按照每个调频组合的能效比对多个调频组合进行排序，其中，随着档位提升，能效比依次递增。当需要提升SOC的工作频率时，可以提升调频组合的一个档位，然后监控5帧图像的实际绘制时长，确定该5帧图像的实际绘制时长是否降低到5帧图像的理论绘制时长内，如果降低到5帧图像的理论绘制时长内，则可以在连续2个调频周期内提升SOC的工作频率后结束。如果在提升一个档位之后5帧图像的实际绘制时长仍然超过5帧图像的理论绘制时长，则可以再次提升一个档位，依次类推。本申请实施例中的调频周期可以为一个理论绘制时长(如16.6ms)，也可以为预设时间段(如4ms)，本申请实施例不做限定。
在本申请实施例中，在帧率出现大幅波动的情况下，结合实际绘制时长、SOC的当前负载以及当前温度，判断是否为突发资源高需求。在判断突发资源高需求的情况下调整SOC的工作频率，保障SOC的及时充分供给，从而减小功耗以及帧率的大幅波动。

S1004，确定SOC的当前负载是否大于第二预设阈值，若大于，则执行S1005，若不大于，则跳转到S1002，执行S1002的步骤。其中，第二预设阈值可以为70％。
