本发明的较佳实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。
图1为本发明的调频参数的调节方法实施例一的流程图。如图1所示,本实施例的调频参数的调节方法,具体可以包括如下步骤:
100、获取采用governor调频模式对CPU调频时,CPU运行预设代码所对应的归一化数值;
首先,本实施例的预设代码为一段较为复杂的程序,其中包括加减乘除与或非等等运算。这段程序在启动若干时间之后(假设时间为Time)会使得CPU处在最高频率点上。也就是说,采用governor调频模式对CPU调频时,在启动到运行预设代码之后,CPU频率会动态变化直到稳定到最高频率进行高强度的计算,只有进行高强度计算耗费的时间才能判别此governor调频模式的效率。本实施例中,CPU运行预设代码所对应的归一化数值即是在该条件下所对应的归一化数值。
101、判断归一化数值是否大于预设归一化阈值;当归一化数值大于预设归一化阈值,执行步骤102;否则当归一化数值等于预设归一化阈值,暂不执行任何操作。
本实施例中的预设归一化阈值为使CPU以维持移动终端基本性能运行所需频率,运行预设代码所对应的归一化的数值位。也就是说,该预设归一化阈值为保证移动终端最基本性能运行所对应的值。只要能够保证该预设归一化阈值,即能够保证用户的体验度,不影响用户对移动终端的基本使用。
当归一化数值等于预设归一化阈值,此时说明CPU已处于最低性能,仅保证移动终端的基本功能,也就是说移动终端目前处于不影响用户体验的最低能耗状态,最省电状态下。本实施例中,不存在归一化数值小于预设归一化阈值的情况,因为预设归一化阈值已经为不影响用户体验的最小的归一化数值位,不可能存在更低的不影响用户体验的归一化数值位。
102、调节governor调频模式的调频参数,使得归一化数值靠近预设归一化阈值,以调节CPU的能耗。
由于本实施例中的预设归一化阈值为移动终端的不影响用户体验的最低能耗状态,最省电状态下对应的数值位,当归一化数值大于预设归一化阈值时,说明移动终端的工作状态还可以调整,以达到不影响用户体验,能耗
最佳的最省电状态。本实施例中,通过调节移动终端的CPU的频率的调频器的governor调频模式的调频参数进行调节,使得归一化数值靠近预设归一化阈值,以调节CPU的能耗,使得CPU在保证不影响用户体验的前提下,能耗最低,最省电,从而也就增强了移动终端的续航能力。
本实施例的调频参数的调节方法,通过获取采用governor调频模式对CPU调频时,CPU运行预设代码所对应的归一化数值,判断归一化数值是否大于预设归一化阈值;当归一化数值大于预设归一化阈值,调节governor调频模式的调频参数,使得归一化数值靠近预设归一化阈值,以调节CPU的能耗,从而使得CPU在保证不影响用户体验的前提下,能耗最低,最省电。本实施例的调频参数的调节方案,通过对移动终端的调频器的governor调频模式的调频参数的调节,可以使得移动终端的CPU的性能处于不影响用户体验的最佳状态,且能够保证移动终端的CPU的功耗最小,最省电,因此,可以有效地增强了移动终端电池的续航能力,且经过Linux kernel或者google提供的CPU的governor调频模式对本实施例的方案进行验证,可以发现采用本实施例的方案,可以为移动终端的电池增加至少百分之五的平均续航时间。
图2为本发明的调频参数的调节方法实施例二的流程图。如图2所示,本实施例的调频参数的调节方法在上述图1所示实施例的技术方案的基础上,以CPU单核时为例来描述本发明的技术方案。如图2所示,本实施例的调频参数的调节方法,具体可以包括如下步骤:
200、在CPU运行预设代码过程中,采用governor调频模式对CPU调频时,获取CPU运行预设代码所需的第一平均时间;
本实施例中,在CPU运行预设代码过程中,采用governor调频模式对CPU调频时,可以让CPU运行多次该预设代码,例如根据实际应用场景,可以运行20次或者30次等次数,然后统计运行多次该预设代码的总时间,并用总时间处于运行的总次数得到CPU运行该预设代码依次的平均时间,即第一平均时间。本实施例中,为了保证第一平均时间的准确性,本实施例通过让CPU运行多次该预设代码,得到更加准确的数值。具体预设次数还可以根据实际需求设置为其他数值,在此不做限定。
201、在CPU运行预设代码过程中,采用performance调频模式对CPU调频时,获取CPU运行预设代码所需的第二平均时间;
本实施例中,performance调频模式具体为让将CPU的频率调为最高频率。同理,本实施例中也可以在CPU以最高频率运行对该预设代码运行预设次数,具体也可以为20次或者30次,以得到更加准确的第二平均时间。
另外,本实施例中步骤200和步骤201可以没有先后顺序限制。
202、根据第一平均时间和第二平均时间,并以第二平时时间为基准,计算CPU运行预设代码所对应的归一化数值;
具体地,CPU运行预设代码所对应的归一化数值具体可以采用如下公式来表示:X*100/Y,其中X表示第一平均时间,Y表示第二平均时间,将整体归一化为100,所以又乘以100。
本实施例的步骤200-202为上述图1所示实施例的步骤100的一种具体实现方式。
203、判断归一化数值是否大于预设归一化阈值;当归一化数值大于预设归一化阈值,执行步骤204;否则当归一化数值等于预设归一化阈值,暂不执行任何操作。
具体地,在该步骤203之前,还可以包括计算预设归一化阈值。该预设归一化阈值(可以表示为N)的具体计算过程,与上述归一化数值的获取过程相似,具体可以采用如下方式:关闭governor调频模式,获取维持移动终端最基本性能运行所对应的最低频率,并使得CPU在该频率下运行该预设代码预设次数C1,统计该CPU运行该预设代码预设次数的总时间T1,得到该CPU在该频率下运行该预设代码的时间平均值X1=T1/C1;然后让CPU在Performance模式下运行该预设代码预设次数C2,即使得CPU在最高频率下运行该预设代码预设次数C2,此时统计该CPU运行该预设代码预设次数的总时间T2,得到该CPU在该频率下运行该预设代码的时间平均值Y1=T2/C2;然后根据公式N=X1*100/Y1,从而可以计算得到预设归一化阈值N。
204、调节governor调频模式的调频参数,使得归一化数值靠近预设归
一化阈值,以调节CPU的能耗。
例如,本实施例中调节governor调频模式的调频参数,具体包括如下至少一种:
调节governor调频模式的采样周期;
调节governor调频模式的升高频率的门限;
调节governor调频模式的降低频率的门限;
调节CPU是否接受突发大负载的响应;以及
调节CPU处于最高频率的持续时间。
需要说明的是,governor调频模式的调频参数并不仅仅限制为以上几种,实际应用中,还可以包括类似的其他的调频参数,在此不再一一举例赘述。本实施例的步骤203和步骤204的其他具体实现方式可以参考上述图1所示实施例的步骤101和步骤102的记载,在此不再赘述。

同理,步骤300和步骤301无先后时序限制。
302、根据第三平均时间和第四平均时间,并以第四平时时间为基准,计算CPU运行预设代码所对应的归一化数值;
本步骤的具体实现方式与上述图2所示实施例的步骤202的实现方式相同,详细可以参考上述实施例的相关记载,在此不再赘述。
本实施例的步骤300-302为上述图1所示实施例的步骤100的一种具体实现方式。
303、判断归一化数值是否大于预设归一化阈值;当归一化数值大于预设归一化阈值,执行步骤204;否则当归一化数值等于预设归一化阈值,暂不执行任何操作。
304、调节governor调频模式的调频参数,使得归一化数值靠近预设归一化阈值,以调节CPU的能耗。
本实施例的步骤303和步骤304可以参考上述图2所示实施例的步骤203和步骤204的具体实现方式,详细参考上述实施例的相关记载,在此不再赘述。
本实施例的调频参数的调节方法,通过采用上述方案对governor调频模式的调频参数进行调节,可以使得归一化数值靠近预设归一化阈值,以调节CPU的能耗,从而使得CPU在保证不影响用户体验的前提下,能耗最低,最省电。本实施例的调频参数的调节方案,通过对移动终端的调频器的
