技术领域
本发明涉及通信技术领域, 尤其一种芯片能耗控制的方法、 装置和系统。 背景技术
随着通信技术的不断发展, 网络设备的处理能力越来越强大, 数据处理 速度越来越高, 随之而来的问题是网络设备的功耗也越来越大, 增加了工程 设计的难度以及运营成本, 因此, 通信设备的能耗控制需求日益迫切。
通信芯片的能耗控制一般是通过使芯片或芯片内部功能模块进入节能模 式来实现。 在节能模式下, 系统会切断芯片或芯片内部功能模块的电源, 或 者关闭芯片或芯片内部功能模块的时钟信号, 以达到节能的效果。 现有的通 信芯片能耗控制方法是根据芯片或芯片内部功能模块与当前工作系统之间物 理连接的通断来控制其向节能模式的切换。 例如系统检测到某一芯片或芯片 内部功能模块与其之间物理连接断开, 那么系统就会向电源电路和 /或时钟电 路发出控制信息, 切断所述芯片或芯片内部功能模块的电源和 /或时钟信号, 从而所述芯片或芯片内部功能模块切换至节能模式。

具体实施方式
为了解决现有芯片能耗控制技术节能效率不高的问题, 本发明实施例提 供了一种芯片能耗控制的方法、 装置和系统。
如图 1所示, 一种芯片能耗控制方法, 包括:
101、 监测是否有报文传输至芯片;
102、 如果没有报文传输到芯片, 将所述芯片切换到节能模式。 所述节能模式是指给芯片下电。 本发明实施例首先判断芯片是否接收报 文; 如果检测到芯片没有接收报文, 则使所述芯片处于节能模式。 解决了芯 片与系统保持着物理连接, 此时虽然没有用户数据传输, 却无法使所述芯片 切换到节能模式的问题, 从而提高了节能的效果。
对于不同工作机制的芯片或者芯片的内部模块应釆取不同的能耗控制策 略。 例如, 对于动态随机存储器(DRAM) , 由于其需要周期性的动态刷新, 因 此即使没有报文传输到所述动态随机存储器时, 也不能对其下电或关闭其时 钟。 如果监测到有报文传输到芯片, 就将芯片切换回工作模式。 当芯片接收到的报文数量较少, 或者报文传输速率较小时, 如果芯片一 直处于工作模式进行处理的话, 也在一定程度上浪费了能量, 因此可以先将 报文存储于緩存当中, 等緩存当中的报文数量积攒到一定程度时, 再将芯片 切换回工作模式, 对所述 文进行统一处理。
如图 2 所示、 根据緩存内存储的报文数量, 来改变芯片的工作模式, 其 主要步骤包括:
201、 为芯片设置高切换阔值和低切换阔值;
202、 监测是否有报文传输至芯片;
203、 如果有报文传输到芯片, 将所述报文存储于緩存当中;
当有报文传输到芯片, 将所述报文存储于緩存当中, 芯片暂时先不对所 述报文进行处理, 实时监测緩存当中的报文数量。
204、 当緩存当中报文的数量达到所述高切换阔值时, 将所述芯片切换到 工作模式;
当报文数量不断增多, 达到所设定的高切换阔值时, 将芯片切换到工作 模式, 芯片开始对报文进行处理。
205、 当緩存当中报文的数量低于所述低切换阔值时, 将所述芯片切换回 节能模式。
一般来讲, 芯片处理报文的速度要高于报文的传输速度, 随着芯片的处 理, 緩存当中的报文数量不断减少, 当緩存当中报文的数量低于所述低切换 阔值时, 将所述芯片切换回节能模式。
如图 3所示, thl与 th2为设置的高切换阔值和低切换阔值, 某种业务的数 据在 T1到 T5期间一直以较低的平均速率到达, T1到 T2, 期间芯片中相应的业 务处理模块对报文不进行处理, 而是先把报文暂存在报文緩存里, 到 Τ2, 时 刻, 緩存中的报文数量达到 thl , 这时, 报文检测装置根据緩存的填充水平控 制业务处理模块以时钟频率 f l进行处理报文, 到 T2时刻, 緩存中的报文数量 下降到 th2 , 业务处理模块将被切换回节能模式, 具体实现时也可使业务处理 模块处于极度节能模式。 图 3中 T2到 T5期间业务处理模块的模式转换可以参考 T1到 T2期间的能耗转换过程。
为了取得更高的节能效率, 还可以对处于工作模式下的芯片进行更细致 的管理。 芯片进入工作模式之后, 根据为其提供的工作时钟频率进行工作, 工作时钟频率越高, 芯片运转速度越快, 能耗也就越大; 工作时钟频率越低, 芯片运转速度越慢, 能耗也就越小。 因此, 可以根据芯片所负载的流量状况 为芯片选择适当的工作时钟频率, 对芯片进行能耗管理。
本发明实施例可以分别根据芯片处理业务所要求的服务质量等级或者报 文传输到芯片的平均速率, 来改变芯片的工作时钟频率, 下面将分别进行详 细描述:
如图 4 所示, 根据芯片处理业务所要求的服务质量等级来改变芯片的工 作时钟频率, 其主要步骤包括:
401、 为所述芯片或芯片内部不同的功能模块设置至少两种工作时钟频 率;
根据芯片处理业务类型对服务质量等级的要求来为芯片或芯片内部不同 的功能模块设置不同的工作时钟频率; 业务要求的服务质量等级较高, 工作 时钟频率就要设置的较高; 业务要求的服务质量等级较低, 工作时钟频率就 可以设置的较低。
402、 如果有报文传输到芯片, 获取当前传输到芯片的报文的业务类型, 并获取业务类型所需要的服务质量等级;
根据传送来的报文, 来分析业务的类型, 从而获得业务所需要的服务质 量等级。
403、根据业务所需要的服务质量等级,为芯片选取相应的工作时钟频率。 如果芯片处理的业务中, 既包含服务质量等级要求较高的业务, 如实时 业务, 又包含服务质量等级要求较低的业务, 可首先对报文流进行分类, 然 后再对芯片进行节能控制, 即将实时业务的报文流分离出来, 统一汇聚到芯 片中指定的业务处理模块进行处理, 对所述指定模块不进行能耗控制或选取 较高的工作时钟频率, 而对处理其余服务质量等级要求较低业务的处理模块, 可选取较低的时钟频率进行能耗控制。
如图 5 所示, 根据报文传输到芯片的平均速率来改变芯片的工作时钟频 率, 其主要步骤包括:
501、 为所述芯片设置至少两种工作时钟频率;
根据传输到芯片的报文平均速率来设置不同的工作时钟频率; 报文传输 到芯片的平均速率较高, 工作时钟频率就要设置的较高; 报文传输到芯片的 平均速率较低, 工作时钟频率就可以设置的较低;
502、 设置至少一个报文传输速率阔值;
报文传输速率阔值的设置是为了给报文传输的平均速率划分等级, 不同 的等级对应着不同的工作时钟频率;
503、 如果有报文传输到芯片, 获取报文传输的平均速率;
504、 将所述报文传输的平均速率与设置的报文传输速率阔值相比较, 并 根据比较结果控制芯片釆用相应的工作时钟频率; 即通过将当前报文传输平 均速率与设置的报文传输速率阔值进行比较, 获得当前报文传输平均速率所 对应的平均速率等级, 进而根据所述等级为芯片选取工作时钟频率。
如图 6所示,图中的 f l , f2代表为芯片设置的两种不同的工作时钟频率, R1为设置的报文传输速率阔值。 在 T1到 T2时间段内, 报文传输的平均速率 低于 R1 , 为芯片设置较低的工作时钟频率 f2; 在 T2到 T3时间段内, 报文传 输的平均速率高于 R1 , 则调整业务处理功能电路的时钟频率为较高的工作时 钟频率 f l。
在上述实施例中, 只设置了一个报文传输速率阔值 R1 , 在实际应用中可 以根据需要, 设置多个阔值以及阔值对应的工作时钟频率, 从而实现对芯片 更精细的能耗管理。
本发明实施例芯片能耗控制装置, 如图 7所示, 包括:
监测报文模块 701 , 用于监测有无报文传输至芯片;
模式切换模块 702 ,用于所述监测报文模块的监测结果是没有报文传输至 芯片, 将所述芯片切换到节能模式。
可选地, 所述模式切换模块还用于所述监测报文模块的监测结果是有报 文传输到芯片时, 将所述芯片切换到工作模式。
可选地, 所述模式切换模块, 包括:
阔值设置单元, 用于对应芯片不同的工作模式, 设置不同的切换阔值; 例如, 为芯片的节能模式设置一低切换阔值, 为芯片的工作模式设置一高切 换阔值;
