附图说明
图1为本公开实施例1提供的一种系统级芯片的结构示意图。
图2为本公开实施例1提供的一种系统级芯片的工作模式管理方法的流程图。
具体实施方式
下面通过实施例的方式进一步说明本公开，但并不因此将本公开限制在所述的实施例范围之中。
实施例1
图1是用于示出一种系统级芯片的结构示意图。本实施例提供的系统级芯片的工作模式管理方法可以应用于图1所示的系统级芯片。如图1所示，系统级芯片包括主控子系统、副控子系统以及多个功能子系统。其中，主控子系统和副控子系统分别通过中断线与所述功能子系统连接，主控子系统与副控子系统通过中断线连接。
本实施例提供一种系统级芯片的工作模式管理方法，如图2所示。
在工作模式下，执行以下步骤：
步骤S100、所述主控子系统控制所述功能子系统执行相应的功能，并响应所述功能子系统以及所述副控子系统的中断信号。
本实施例中，不同的功能子系统用于实现不同的功能，功能子系统仅在需要时才打开进行工作，不需要时则进入休眠状态，只保持微弱的待机电流，甚至需要断电，以彻底节省功耗。例如无线Modem子系统包括无线Modem，用于实现接听/拨打电话、移动数据网络等功能。无线Modem一般由基带处理、调制解调、信号放大和滤波、均衡等几部分组成，用于将数据通信的数字信号在具有有限带宽的模拟信道上进行无线传输。蓝牙子系统用于实现与短距离内的外部设备进行无线通信功能。Wi-Fi(无线通信技术)子系统用于实现无线上网功能。GPS(Global Positioning System，全球定位系统)子系统用于实现在全球范围内实时定位、导航的功能。相机子系统包括摄像头，用 于捕获静态图像或视频。
步骤S101、判断主控子系统在一段时间内是否接收到任何功能子系统发送的数据，若是，则返回步骤S100，若否，则切换至休眠模式。其中，一段时间可以根据具体情况进行设置，例如设为1分钟。
在休眠模式下，执行以下步骤：
步骤S200、所述副控子系统响应所述功能子系统的中断信号，所述主控子系统禁止响应所述功能子系统的中断信号。在具体实施的一个例子中，将主控子系统与各个功能子系统连接的中断口禁止使能，从而使主控子系统无法响应各功能子系统发送的中断信号。
步骤S201、判断所述副控子系统是否检测到所述功能子系统的中断信号，若是，则切换至工作模式，若否，则执行步骤S202；
步骤S202、判断是否满足预设条件，若是，则切换至超低功耗模式，若否，则返回步骤S200。
在可选的一种实施方式中，上述预设条件为系统时间达到预设时间。在一个具体的例子中，预设时间为凌晨两点。在休眠模式下，若系统时间达到凌晨两点，则切换至超低功耗模式。
在可选的一种实施方式中，所述副控子系统与外部传感器连接，上述方法还包括：所述副控子系统接收所述外部传感器的检测数据。
在可选的另一种实施方式中，上述预设条件为外部传感器的检测数据低于一定值。在一个具体的例子中，副控子系统与心率传感器连接，若心率传感器检测的心率数据低于60次/分钟，则切换至超低功耗模式。
在超低功耗模式下，执行以下步骤：
步骤S300、所述主控子系统掉电，所述副控子系统响应所述功能子系统的中断信号。
在步骤S300可选的一种实施方式中，为了节省更多的功耗，主控子系统先控制部分功能子系统掉电，例如向其电源域输出预设电平，然后再自行 掉电。在超低功耗模式的一个例子中，无线Modem子系统处于掉电状态，即无法进行接听/拨打电话。
在可选的一种实施方式中，所述主控子系统、所述副控子系统以及所述功能子系统均具有独立的电源域，也就是说，各个子系统可以独立上电或掉电，互不影响。在一个具体的例子中，主控子系统向功能子系统的电源域输出预设电平信号，以控制功能子系统的上电或掉电。在另一个具体的例子中，副控子系统向主控子系统的电源域输出预设电平信号，以控制主控子系统的上电。
步骤S301、判断是否所述副控子系统检测到所述功能子系统的中断信号或不满足所述预设条件，若是，则控制所述主控子系统上电，并切换至工作模式，若否，则返回步骤S300。
在可选的一种实施方式中，在超低功耗模式下，若所述副控子系统检测到外部传感器的检测数据异常，则控制所述主控子系统上电，并切换至工作模式。在一个具体的例子中，副控子系统与心率传感器连接，若副控子系统检测到心率数据超过120次/分钟，则控制主控子系统上电，并切换至工作模式。
在可选的一种实施方式中，上述主控子系统和所述副控子系统均与外部操作设备连接。
在工作模式下，将上述步骤S101替换为以下步骤S101’：
步骤S101’、判断所述主控子系统在一段时间内是否接收到任何功能子系统发送的数据或者用户在所述外部操作设备上的操作，若是，则返回步骤S100，若否，则切换至休眠模式。
在休眠模式下，将上述步骤S201替换为以下步骤S201’：
步骤S201’、判断所述副控子系统是否检测到所述功能子系统的中断信号或者用户在所述外部操作设备上的操作，若是，则切换至工作模式，若否，则执行步骤S202。
在超低功耗模式下，将上述步骤S301替换为以下步骤S301’：
步骤S301’、判断是否所述副控子系统检测到所述功能子系统的中断信号、用户在所述外部操作设备上的操作或不满足所述预设条件，若是，则控制所述主控子系统上电，并切换至工作模式，若否，则返回步骤S300。
在一个例子中，外部操作设备包括触摸屏，用户可以在触摸屏上执行点击、触摸、滑动等操作。在工作模式下，主控子系统用于接收用户在触摸屏上的触摸操作，在休眠模式和超低功耗模式下，副控子系统用于接收用户在触摸屏上的触摸操作。
在另一个例子中，外部操作设备还包括按键，用户可以对按键执行按下一次、按下两次、短按或者长按等操作。在工作模式下，主控子系统用于接收用户对按键的操作，在休眠模式和超低功耗模式下，副控子系统用于接收用户对按键的操作。
本实施方式中，主控子系统可完成复杂的多媒体系统应用，并能完整的响应用户操作，甚至能执行复杂的用户应用程序。副控子系统主要用于主控子系统休眠时的AOD显示和各种外部传感器的控制。因此，主控子系统中MCU(Micro Control Unit，微控制单元)的主频、内存消耗以及功耗均高于副控子系统中MCU的主频、内存消耗以及功耗。
本实施例中，通过主控子系统和副控子系统交替响应功能子系统的中断信号，为系统级芯片提供了三种模式，具体为工作模式、休眠模式以及超低功耗模式，在满足系统级芯片正常功能需求的前提下，最大限度地节省了系统级芯片的功耗。
