Description

数据处理方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及数据处理方法及装置。
背景技术
随着通信技术的快速发展，基于电容式触摸屏的移动终端得到了广泛应用，移动终端上越来越多的应用程序也使用触摸操作替代传统的按键，比如，输入法，游戏按键等等。
由于电容式触摸屏的响应时间大约在100ms，当用户滑动屏幕，通过触摸操作替代游戏按键的时候，用户期望操作就像现实拖动的感觉，也就是说，用户期望移动终端显示界面的显示图像可以随着用户的触摸操作进行实时的变化显示。
目前，当触摸屏将报点数据发送给移动终端的应用处理器进行数据处理时，应用处理器通常是采用中断的方式，且由于中断的数量有限性，通常是多个通用输入输出GPIO共享一个中断，因此触摸屏的报点数据很有可能被其他的中断锁定，或者在某一中断对应的工作队列WQ中等待处理，因此，导致报点数据的处理存在延迟响应的问题。另外，由于报点数据的上报速率与显示器的显示速率不是倍数关系，因此每一个上报点与显示器的帧不能完全同步，且每一个点的延迟都不相同，从而导致图像显示时出现拖动不均匀的问题。
发明内容
本发明的实施例提供一种数据处理方法及装置，解决了现有技术中终端对报点数据进行处理时响应速度慢、以及拖动不均匀的问题。
为达到上述目的，本发明的实施例采用如下技术方案：
第一方面，提供一种数据处理方法，该方法应用于终端，该终端中设置有触摸屏、微处理器和应用处理器，该方法包括：触摸屏生成报点数据，并根据预设报点上报率上报该报点数据至微处理器，该报点数据中包括触摸屏被触摸时的触点信息；微处理器接收该报点数据；微处理器接收应用处理器发送的帧同步信号，帧同步信号为与显示帧率同步的周期信号；微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的报点数据，并将第二数量的报点数据传输至应用处理器，第二数量小于第一数量；应用处理器接收第二数量的报点数据，并根据第二数量的报点数据生成显示图像帧。
第二方面，提供一种数据处理装置，该装置包括：检测单元，用于生成报点数据，根据预设报点上报率上报该报点数据至第一处理单元，该报点数据中包括检测单元被触摸时的触点信息；第一处理单元，用于接收该报点数据；第一处理单元，还用于接收第二处理单元发送的帧同步信号，帧同步信号为与显示帧率同步的周期信号；第一处理单元，还用于根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的报点数据，并将第二数量的报点数据传输至第二处理单元，第二数量小于第一数量；第二处理单元，用于接收第二数量的报点数据，并根据第二数量的报点数据生成显示图像帧。
第三方面，提供一种终端，该终端包括：触摸屏、微处理器和应用处理器；其中，触摸屏，用于生成报点数据，根据预设报点上报率上报该报点数据至微处理器，该报点数据中包括触摸屏被触摸时的触点信息；微处理器，用于接收该报点数据；微处理器，还用于接收应用处理器发送的帧同步信号，帧同步信号为与显示帧率同步的周期信号；微处理器，还用于根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的报点数据，并将第二数量的报点数据传输至应用处理器，第二数量小于第一数量；应用处理器，用于接收第二数量的报点数据，并根据第二数量的报点数据生成显示图像帧。
上述技术方案中，对于第一数量的报点数据是根据帧同步信号，并以并行处理方式对第一数量的报点数据包括的多个报点数据进行处理，而不是通过中断的方式进行处理，因此，避免了对报点数据的处理存在中断延迟和工作队列延迟的问题，同时也解决了显示图像拖动不均匀的问题。
可选的，基于第一方面，微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的第二报点数据，包括：
微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据。
可选的，基于第二方面，第一处理单元具体用于：根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据。
可选的，基于第三方面，微处理器具体用于：根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据。
上述可选的技术方案中，通过帧同步信号对预设时间内接收的第一数量的报点数据进行采样，使得帧同步信号的每个周期内都对应第二数量的报点数据中的一个采样点，保证了报点数据和显示的同步。
可选的，基于第一方面，微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样之前，该方法还包括：微处理器确定第一数量的报点数据的精度是否小于目标采样精度；若确定第一数量的报点数据的精度小于目标采样精度，微处理器对第一数量的报点数据进行插值处理，得到第三数量的报点数据，第三数量大于第一数量；相应的，微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据，包括：微处理器根据帧同步信号对插值处理后的第三数量的报点数据进行采样，得到第二数量的报点数据。
可选的，基于第二方面，第一处理单元还用于：确定第一数量的报点数据的精度是否小于目标采样精度；若确定第一数量的报点数据的精度小于目标采样精度，对第一数量的报点数据进行插值处理，得到第三数量的报点数据，第三数量大于第一数量；相应的，第一处理单元具体用于：根据帧同步信号对插值处理后的第三数量的报点数据进行采样，得到第二数量的报点数据。

上述可选的技术方案中，当第一数量的报点数据的精度小于目标采样精度时，代表第一数量的报点数据不足以根据帧同步信号进行采样，因此微处理器需要先对该报点数据进行内插值处理，然后再根据该帧同步信号对处理后的报点数据进行采样。
可选的，基于第一方面，微处理器得到第二数量的报点数据之后，该方法还包括：微处理器确定第二数量的报点数据所对应的用户动作，并将确定结果传输至应用处理器，用户动作包括触摸动作或滑动动作。
可选的，基于第二方面，第一处理单元还用于：确定第二数量的报点数据所对应的用户动作，并将确定结果传输至第二处理单元，用户动作包括触摸动作或滑动动作。
可选的，基于第三方面，微处理器还用于：确定第二数量的报点数据所对应的用户动作，并将确定结果传输至应用处理器，用户动作包括触摸动作或滑动动作。
上述可选的技术方案中，由微处理器确定第二数量的报点数据所对应的用户动作，并将确定结果传输至应用处理器，提高了应用处理器根据第二数量的报点数据生成显示图像帧的速率。
可选的，基于第一方面，触摸屏生成报点数据，根据预设报点上报率上报该报点数据至微处理器之前，该方法还包括：触摸屏接收应用处理器发送的显示帧率；触摸屏根据显示帧率确定预设报点上报率。
可选的，基于第二方面，检测单元还用于：接收第二处理单元发送的显示帧率；根据显示帧率确定预设报点上报率。

上述可选的方案中，通过根据接收的显示帧率确定预设报点上报率，可以使预设报点上报率与图像显示时的显示帧率一致，这样，每一次上报的报点数据都会表现在显示的图像中，从而与现有技术中触摸屏按照固定频率传输报点数据相比，避免了因固定频率传输报点数据而生成显示图像的浪费问题，同时也减少了终端的一部分功耗。
可选的，基于第一方面，当触摸屏在预设时间段内没有检测到触摸操作时，应用处理器停止向微处理器发送帧同步信号。
可选的，基于第二方面，第二处理单元还用于：当检测单元在预设时间段内没有检测到触摸操作时，停止向第一处理单元发送帧同步信号。
可选的，基于第三方面，应用处理器还用于：当触摸屏在预设时间段内没有检测到触摸操作时，停止向微处理器发送帧同步信号。
上述可选的技术方案中，当检测不到触摸操作时，可以停止发送帧同步信号，可以减少发送帧同步信号给该终端带来的功耗。
可选的，基于第一方面，微处理器将第二数量的报点数据传输至应用处理器之前，该方法还包括：微处理器对第二数量的报点数据进行低通滤波处理。
可选的，基于第二方面，第一处理单元还用于：对第二数量的报点数据进行低通滤波处理。
可选的，基于第三方面，微处理器还用于：对第二数量的报点数据进行低通滤波处理。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供的数据处理方法可以由终端执行，该终端可以为手机、平板电脑、笔记本电脑、UMPC(Ultra-mobile Personal Computer，超级移动个人计算机)、上网本、PDA(Personal Digital Assistant，个人数字助理)等等。图1示出的是与本发明各实施例相关的终端的部分结构框图。如图1所示，该终端10包括：应用处理器101、微处理器102和触摸屏103。
其中，应用处理器101和微处理器102是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，且具有数据处理功能，应用处理器101主要处理操作系统、用户界面和应用程序等，微处理器102可以代替应用处理器101执行一部分指令或具有应用处理器101的部分功能。同时，应用处理器101和微处理器102之间还可以进行通信，即应用处理器101和微处理器102之间可以进行数据传输，且该数据传输可以是双向传输。当然，应用处理器101与微处理器102可以集成到处理器中，也可以单独设置。该微处理器可以是功耗较小的处理芯片，比如，该微处理器可以是具有软件编程功能的单片机MCU、数字信号处理芯片DSP、传感器中心SensorHub、或者是可编程逻辑器件等，该微处理器的价格便宜，功耗也比较小。比如，该微处理器可以为美国德州仪器开发的微处理器MSP430、 恩智浦半导体公司开发的LPC18A1、或者STM32L151RB等。
另外，触摸屏103可以分为触摸屏感应器和触摸屏控制器，触摸屏感应器用于检测用户触摸触摸屏时的触点信息，用户触摸触摸屏时的用户动作可以是触摸动作，也可以是滑动动作。触摸屏感应器接收触点信息后将相应的指令发送给触摸屏控制器，触摸屏控制器的主要作用是从触摸屏感应器上接收触点信息，并将它转换成触点坐标，再发送给终端的处理器，该处理器包括应用处理器101和微处理器102，它同时能接收终端的处理器发来的命令并加以执行。
进一步的，参见图2，该终端还可以包括存储器104、传感器组件105、电源组件106、以及输入\输出接口107等。
其中，存储器104可用于存储数据、软件程序以及模块；主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序等；存储数据区可存储根据终端的使用所创建的数据等。此外，存储器104可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
传感器组件105包括一个或多个传感器，用于为终端提供各个方面的状态评估。其中，传感器组件105可以包括加速度传感器，陀螺仪传感器，磁传感器，压力传感器或温度传感器等，通过传感器组件可以检测到终端的加速/减速、方位、打开/关闭状态，组件的相对定位，或终端的温度变化等。此外，传感器组件还可以包括光传感器，如CMOS或CCD图像传感器，用于在成像应用中使用。

尽管未示出，终端还可以包括音频组件、多媒体组件和通信组件等，比如，音频组件包括麦克风，多媒体组件包括摄像头，通信组件包括WiFi(wireless fidelity，无线保真)模块、蓝牙模块等，本发明实施例在此不再赘述。
本领域普通技术人员可以理解，图1、图2所示的硬件结构仅为示意，其并不对中终端的结构造成限定。该终端还可包括比图1、图2中所示更多或者更少的组件，或者具有与图1、图2所示不同的配置。
图3为本发明实施例提供的一种数据传输方法的流程示意图，参见图3，该方法应用于图1或图2所示的终端，该方法包括以下几个步骤。
步骤201：触摸屏生成报点数据，根据预设报点上报率上报该报点数据至微处理器，该报点数据中包括触摸屏被触摸时的触点信息。
该触摸屏可以包括触摸屏感应器和触摸屏控制器，触摸屏感应器用于检测触摸操作，并将触摸操作对应的触摸信息发送给触摸屏控制器，当触摸屏控制器接收到该触摸信息时，将该触摸信息转换成对应的报点数据，以及根据预设报点上报率将该报点数据上报给微处理器。其中，该报点数据包括的触摸屏被触摸时的触点信息可以为触点坐标。另外，该触摸屏感应器检测的用户动作可以为触摸操作，比如，单击、双击、长按等操作，也可以为滑动操作，比如，上下滑动、左右滑动等。
需要说明的是，预设报点上报率是指触摸屏在预设报点向微处理器上报报点数据的频率，该预设报点上报率可以事先进行设置，在可以在触摸屏上报该报点数据 之前进行设置，本发明实施例对此不作限定。
比如，当用户在触摸屏上通过滑动操作作为游戏按键使用的时候，用户可以通过上下滑动、左右滑动等不同的触摸操作触发不同的控制指令，当触摸屏在检测到该触摸操作时，可以生成与该触摸操作对应的报点数据，并按照预设报点上报率将该报点数据上报至微处理器，其中，该报点数据包括与用户的滑动操作对应的触点信息。
步骤202：微处理器接收报点数据，该报点数据中包括触摸屏被触摸时的触点信息。
其中，步骤202中的报点数据与步骤201中的报点数据一致，本发明实施例在此不再赘述。
步骤203：微处理器接收应用处理器发送的帧同步信号，该帧同步信号为与显示帧率同步的周期信号。
其中，显示帧率是用于测量显示帧数的量度，即每秒显示帧数。帧同步信号为与显示帧率同步的周期信号，是指该帧同步信号是一个周期信号，且周期的取值与显示帧率有关，且帧同步信号的开始时间和帧显示的开始时间相关。比如，该显示帧率为每秒60帧，则显示一帧的时长约为16ms，则该帧同步信号的周期取值为16ms。
比如，如图4所示，应用处理器根据显示帧率在时间轴t上进行图像显示时的状态如(I)所示，则该帧同步信号可以如(II)或(III)所示。其中，当该帧同步信号如(II)所示时，该帧同步信号在有帧显示时为高电平，没有帧显示时为低电平，即该帧同步信号的高低电平变化的状态与根据显示帧率进行图像显示时的状态相同；当该帧同步信号如(III)所示时，该帧同步信号在有帧显示时为低电平，没有帧显示时为高电平，即该帧同步信号的高低电平变化的状态与根据显示帧率进行图像显示时的状态相反。帧同步信号的具体形态在此不作限定。
相应的，在步骤201中触摸屏生成报点数据，并根据预设报点上报率上报该报点数据至微处理器之前，该方法还可以包括：触摸屏接收应用处理器发送的显示帧率，并根据该显示帧率确定预设报点上报率。当该预设报点上报率确定之后，触摸屏就可以根据确定的预设报点上报率，将生成的报点数据上报至微处理器。
也即是，使触摸屏的预设报点上报率与图像显示时的显示帧率一致，这样，触摸屏每一次上报的报点数据都会表现在显示的图像中，从而与现有技术中触摸屏按照固定频率传输报点数据相比，避免了因固定频率传输报点数据而生成显示图像的浪费问题，同时也减少了终端的一部分功耗。
步骤204：微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的报点数据，并将第二数量的报点数据传输至应用处理器，第二数量小于第一数量。
当微处理器接收到触摸屏上报的报点数据，以及接收到应用处理器发送的帧同步信号时，微处理器可以根据该帧同步信号对预设时间内接收的第一数量的报点数据进行处理，该处理过程可以为：微处理器根据该帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据，该第二数量小于第一数量，在处理得到第二数量的报点数据时，微处理器可以将该第二数量的报点数据传 输至应用处理器。
具体的，如图5所示，当微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样时，由于该帧同步信号是方波周期信号，微处理器可以在该帧同步信号每个周期的方波的上升沿获取一个采样点，从而得到第二数量的报点数据。如图5所示，第一数量的报点数据为A，该帧同步信号为B，第二数量的报点数据为C，这样，该帧同步信号的每个周期内都对应第二数量的报点数据中的一个采样点。
需要说明的是，该预设时间可以事先进行设置，且该预设时间可以是固定不变的，也可以是时常变化的，本发明实施例对此不作限定。
进一步的，在微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据之前，该方法还包括：微处理器确定第一数量的报点数据的精度是否小于目标采样精度；若确定第一数量的报点数据的精度小于目标采样精度，则微处理器对第一数量的报点数据进行插值处理，得到第三数量的报点数据，第三数量大于第一数量。
相应的，微处理器根据帧同步信号对预设时间内接收的第一数量的报点数据进行采样，得到第二数量的报点数据，具体为：微处理器根据帧同步信号对插值处理后的第三数量的报点数据进行采样，得到第二数量的报点数据。
也即是，在对第一数量的报点数据在采样之前，可以先判断第一数量的报点数据的精度是否满足采样时所需的精度，即第一数量的报点数据的精度是否小于目标采样精度。若小于目标采样精度，代表第一数量的报点数据不足以根据帧同步信号进行采样，因此微处理器需要先对该报点数据进行内插值处理，然后再根据该帧同步信号对处理后的报点数据进行采样。若第一数量的报点数据的精度较高，即第一数量的报点数据的精度大于等于目标采样精度时，微处理器无需对该报点数据进行内插值处理，可以直接对第一数量的报点数据进行采样，得到第二数量的报点数据。
其中，当第一数量的报点数据的精度小于目标采样精度时，微处理器对第一数量的报点数据进行插值处理过程与现有技术一致，具体参见相关技术，本发明实施例在此不作阐述。
需要说明的是，目标采样精度可以事先进行设置，也可以在微处理器对该第一数量的报点数据进行处理时进行设置，本发明实施例对此不作限定。
本发明实施例中微处理器对第一数量的报点数据包括的多个报点数据是同时进行处理的，也即是，以并行处理方式对该第一数量的报点数据包括的多个报点数据进行处理。而现有技术中应用处理器对该第一数量的报点数据进行处理时是通过中断的方式进行处理，即将第一数量的报点数据包括的多个报点数据放在中断对应的工作队列中，按照工作队列的顺序依次进行处理，也即是，现有技术中应用处理器是以串行处理方式对该第一数量的报点数据包括的多个报点数据进行处理。因此，本发明实施例解决了现有技术中应用处理器对报点数据的处理存在中断延迟和工作队列延迟的问题，同时也提高了报点数据的处理速度。
进一步的，在微处理器对第一数量的报点数据进行处理，得到第二数量的报点数据的过程中，该微处理器还可以对采样后得到的第二数量的报点数据进行低通滤波处理，从而滤掉该第二数量的报点数据中的噪声，从而提高数据的信噪比。
具体的，由于该第二数量的报点数据在传输和处理的过程中，不可避免的加入了一些噪声，而通常这些噪声的频率都比第二数量的报点数据的频率要高，因此，微处理器可以通过低通滤波的处理方式，滤除该第二数量的报点数据中加入的噪声，从而提高数据的信噪比。其中，低通滤波是一种过滤方式，是指低频率的信号能正常通过，超过设定临界值的高频率的信号则被阻隔、减弱，所以第二数量的报点数据中的噪声可以通过低通滤波进行滤除。
步骤205：应用处理器接收第二数量的报点数据，并根据第二数量的报点数据生成显示图像帧。
当应用处理器接收到第二数量的报点数据时，由于该第二数量的报点数据是微处理器处理后的数据，因此，应用处理器无需对该第二数量的报点数据进行处理，可以直接根据该第二数量的报点数据生成显示图像帧，进而可以将生成的显示图像帧传输至该终端的最前端的应用程序，也即是，用户触发触摸操作的应用程序，该应用程序可以根据该显示图像帧进行显示，从而使得用户在进行触摸操作而产生显示图像帧发生变化时，该终端能够根据生成的显示图像帧快速地对显示画面进行更新和调整，进而提高用户体验。
进一步的，参见图6，在步骤204之后，该方法还包括：
步骤206：微处理确定第二数量的报点数据所对应的用户动作，并将确定结果传输至应用处理器，该用户动作包括触摸动作或滑动动作。
当微处理器得到第二数量的报点数据时，微处理器可以对第二数量的报点数据所对应的用户动作进行确定，也即是，当第二数量的报点数据是由于触摸动作上报的报点数据时，确定该报点数据对应触摸动作，当第二数量的报点数据是由于滑动动作上报的报点数据时，确定该报点数据对应滑动动作，并将确定的结果发送给应用处理器，使得应用处理器在生成显示图像帧时，可以根据相应的图像生成规则，生成对应的显示图像帧。
需要说明的是，步骤206中，微处理也可以确定第一数量的报点数据所对应的用户动作，并将确定结果传输至应用处理器，当微处理根据第一数量的报点数据确定对应的用户动作时，步骤206与步骤203和步骤204可以不分先后顺序，步骤206只需在步骤202之后，在步骤205应用处理器生成显示图像帧之前即可，本发明实施例对此不作限定。
相应的，步骤205中，应用处理器根据第二数量的报点数据生成显示图像帧时，也可以根据确定结果的不同，生成不同的显示图像帧，具体如下所述。
(1)、当该报点数据对应触摸事件时，应用处理器根据触摸图像生成规则，生成第二数量的报点数据中第一个报点数据对应的显示图像帧，之后，应用处理器可以直接根据该触摸图像生成规则，按照第二数量的报点数据中除第一个报点数据以外的其他报点数据的顺序，依次生成除第一个报点数据以外的其他报点数据对应的显示图像帧。
其中，触摸图像生成规则是指生成的显示图像帧不是整个显示区域的显示图像帧，只是与触摸事件对应的触摸区域的显示图像帧。
也即是，当应用处理器根据第二数量的报点数据包括的多个报点数据生成显示图像帧时，应用处理器只需要在生成第一个报点数据对应的显示图像帧时，确定该 报点数据对应的触摸事件或滑动事件，若为触摸事件，则应用处理器在生成第二数量的报点数据中除第一个报点数据以外的其他报点数据对应的显示图像帧时，可以直接以触摸图像生成规则生成对应的显示图像帧。
(2)、当该报点数据对应滑动事件时，应用处理器根据滑动图像生成规则，生成第二数量的报点数据中第一个报点数据对应的显示图像帧，之后，应用处理器可以直接根据滑动图像的生成规则，按照第二数量的报点数据中除第一个报点数据以外的其他报点数据的顺序，依次生成除第一个报点数据以外的其他报点数据对应的显示图像帧。
其中，滑动图像生成规则是指生成的显示图像帧是整个显示区域的显示图像帧。另外，应用处理器根据第二数量的报点数据包括的多个报点数据生成显示图像帧时，与上述触摸事件时一样，应用处理器只需要在生成第一个报点数据对应的显示图像帧时，确定该报点数据对应的触摸事件或滑动事件，在生成第二数量的报点数据中除第一个报点数据以外的其他报点数据对应的显示图像帧时，可以直接按照第一个报点数据的生成规则生成其他报点数据对应的显示图像帧，而无需每个报点数据都确定一次触摸事件或滑动事件。
进一步的，参见图7，该方法还包括：
步骤207：当触摸屏在预设时间段内没有检测到触摸操作时，应用处理器停止向微处理器发送帧同步信号。
当触摸屏在预设时间段内没有检测到触摸操作时，可以确定用户未对该终端的触摸屏进行触摸操作，从而当触摸屏检测不到触摸操作时，应用处理器可以停止向微处理器发送帧同步信号，即应用处理器关闭帧同步信号或者屏蔽掉该帧同步信号，从而可以在触摸屏未检测触摸操作时，减小该终端的功耗。
其中，该触摸操作可以由用户触发，用户可以通过单击、双击、长按、滑动等多种不同的触摸操作进行触发。
在本发明实施例中，触摸屏、微处理、以及应用处理器之间的交互过程如图8所示，触摸屏和微处理器属于低功耗区域，应用处理器属于高功耗区域，图8中的ASRC是指微处理根据帧同步信号对报点数据进行处理的过程，具体的ASRC过程如图9所示。
需要说明的是，触摸屏生成报点数据，将该报点数据上报至微处理器的过程、微处理接收并处理该报点数据的过程、以及应用处理器根据第二数量的报点数据生成显示图像帧的过程，在时间上存在部分重叠的关系，具体如图10所示。
本发明实施例提供的数据处理方法中，触摸屏生成报点数据，根据预设报点上报率上报该报点数据至微处理器，由微处理器接收该报点数据和应用处理器发送的帧同步信号，以及根据帧同步信号对预设时间内接收的第一数量的报点数据进行处理，得到第二数量的报点数据，并将第二数量的报点数据传输至应用处理器，应用处理器接收第二数量的报点数据，并根据第二数量的报点数据生成显示图像帧，从而解决了该报点数据在处理时存在中断延迟和工作队列延迟的问题，提高了报点数据的响应速度，也避免了在拖动时图像显示不均匀的问题，另外，在触摸屏检测不到触摸操作时，应用处理器停止向微处理器发送帧同步信号，从而有效的降低了该终端的功耗。
