在一些实施例中，命令控制器140被配置为在接收到开启命令后开启第二写控制器102、第二时序产生器122和叠加器130，以及在接收到关闭命令后关闭第二写控制器102、第二时序产生器121和叠加器130。如前所述，当命令控制器接收到开启命令时，表明开始执行显示操作，从而进入显示器期间，当接收到关闭命令时，表明不再进行显示，开始进入非显示期间。
这里，通过开启第二写控制器102，可以使得第二写控制器102将人机交互界面信息写入存储器20；通过开启第二时序产生器122，可以使得第二时序产生器122产生第二时序控制信号，该第二时序控制信号发送至第二读控制器112，从而使得第二读控制器112开始执行读取操作；通过开启叠加器130，可以使得叠加器130执行叠加操作。这样可以在显示装置的显示期间实现人机交互界面信息与视频图像的叠加显示。
再者，通过关闭第二写控制器102，可以使得第二写控制器102停止将人机交互界面信息写入存储器20，解除了第二写控制器对存储器的占用；通过关闭第二时序产生器121，从而可以使得第二时序产生器122停止向第二读控制器112发送第二时序控制信号，从而使得第二读控制器112停止读取操作；通过关闭叠加器130，可以使得叠加器130停止叠加操作。这样，可以在显示装置的非显示期间解除人机交互界面信息对存储器的占用，从而降低数据处理装置(例如，FPGA器件)在非显示期间的功耗。
因此，上述实施例可以在显示装置的显示期间实现人机交互界面信息与视频图像的叠加显示，在显示装置的非显示期间解除人机交互界面信息对存储器的占用，从而在不影响人机交互界面信息的显示的情况下降低数据处理装置(例如FPGA器件)在非显示期间的功耗。
在一些实施例中，在第一读控制器111读取视频图像数据和第二读控制器112读取人机交互界面信息的过程中，人机交互界面信息的读取时间可能延迟于视频图像数据的读取时间，这样在对这两个图像数据叠加时，这两个图像数据可能不能对齐。鉴于此，叠加器130还可以被配置为在对视频图像数据和人机交互界面信息进行叠加处理的过程中，将视频图像数据延迟预定时间以使得视频图像数据的时间与人机交互界面信息的时间对齐，并将延迟后的视频图像数据和所述人机交互界面信息进行叠加。这样可以解决视频图像数据的时间和人机交互界面信息的时间不能对齐而影响叠加效果的问题。需要说明的是，这里所述的预定时间可以根据实际需要或实际情况来设置。
在一些实施例中，命令控制器140包括命令检测模块143、第一计数器141和第二计数器142。该命令检测模块143分别电连接至第一计数器141和第二计数器142。第一计数器141分别电连接至第二写控制器102和和第二计数器142。第二计数器142分别电连接至第一时序产生器121、第二时序产生器122和叠加器130。
命令检测模块143被配置为接收开启命令并输出启动信号。
第一计数器141被配置为响应于启动信号对人机交互界面信息的帧同步信号按照第一计数方式计数，并根据第一计数值控制写控制器180将人机交互界面信息写入存储器20。例如，第一计数器141可以根据第一计数值开启第二写控制器102，从而使得第二写控制器102将人机交互界面信息写入存储器20。例如，该第一计数器可以为帧同步信号计数器。这里，人机交互界面信息包含帧同步信号，当出现该帧同步信号时表示出现一帧人机交互界面图像。
第二计数器142被配置为响应于启动信号对第一时序控制信号的帧同步信号按照第二计数方式计数，并根据第二计数值和从第一计数器141接收的第一计数值开启第二时序产生器122和叠加器130。例如，该第二计数器可以为帧同步信号计数器。类似地，第一时序控制信号也包含帧同步信号，当出现该帧同步信号时表示出现一帧视频图像。
在一些实施例中，第一计数方式与第二计数方式相同。例如，第一计数方式和第二计数方式均为计数逐渐增大的方式。
通过上述实施例，实现了命令控制器在接收到开启命令后配置写控制器将人机交互界面信息写入存储器和启动第二时序产生器和叠加器。这里，启动第二时序产生器，可以使得第二读控制器执行对人机交互界面信息的读取操作。
命令检测模块143还被配置为接收关闭命令并输出关闭信号。
第一计数器141还被配置为响应于关闭信号对人机交互界面信息的帧同步信号按照第三计数方式计数，并根据第三计数值控制写控制器180停止将人机交互界面信息写入存储器20。例如，第一计数器141可以根据第三计数值关闭第二写控制器102，从而使得第二写控制器102停止将人机交互界面信息写入存储器20。
第二计数器142还被配置为响应于关闭信号对第一时序控制信号的帧同步信号按照第四计数方式计数，并根据第四计数值关闭第二时序产生器和叠加器。
在一些实施例中，第三计数方式与第四计数方式相同，第一计数方式与第三计数方式相反。例如，第三计数方式与第四计数方式均为计数逐渐减小的方式。
通过上述实施例，实现了命令控制器在接收到开启命令后配置写控制器停止将人机交互界面信息写入存储器和关闭第二时序产生器和叠加器。这里，关闭第二时序产生器，可以使得第二读控制器不再执行对人机交互界面信息的读取操作。
在一些实施例中，第一计数器141被配置为在第一计数值为第一预设值时开启第二写控制器，以及在第三计数值为第二预设值时关闭第二写控制器。例如，第一预设值小于第二预设值。例如，第一预设值为1，第二预设值为14。当然，本领域技术人员能够理解，这里，第一预设值和第二预设值仅是示例性的，该第一预设值和该第二预设值还可以设置为其他值，可以根据实际需要来设置。因此，本公开的范围并不仅限于此。
在一些实施例中，第二计数器142被配置为在第一计数值大于第一预设值且第二计数值发生变化时开启第二时序产生器和叠加器，以及在第四计数值为第三预设值时关闭第二时序产生器和叠加器。在一些实施例中，第二预设值等于第三预设值。例如，第二预设值和第三预设值均为14。当然，本领域技术人员能够理解，这里，第二预设值和第三预设值仅是示例性的，该第二预设值和该第三预设值还可以设置为其他值，可以根据实际需要来确定。因此，本公开的范围并不仅限于此。在该实施例中，通过开启第二时序产生器，进而可以开启第二读控制器，从而可以使得第二读控制器执行读取操作，类似地，通过关闭第二时序产生器，进而可以使得第二读控制器停止读取操作。
在上面的实施例中，通过命令检测模块、第一计数器和第二计数器的控制，可以实现人机交互界面信息与视频图像数据的多次动态同步，从而使得显示装置在降低功耗的同时不影响显示效果。
在一些实施例中，如图2所示，该数据处理装置10'还可以包括第一接收模块151。第一接收模块151电连接至第一写控制器101。第一接收模块151被配置为接收视频图像数据，并将该视频图像数据传输到第一写控制器101。例如，第一接收模块151为SDI(Serial Digital Interface，数字分量串行接口)接收模块。该SDI接收模块用于接收广电领域专业SDI信号，该SDI信号包含视频图像数据。

在一些实施例中，如图2所示，该数据处理装置10'还可以包括第三接收模块153。第三接收模块153电连接至命令检测模块143。第三接收模块153被配置为接收开启命令或关闭命令，并将开启命令或关闭命令传输到命令检测模块143。例如，该第三接收模块153可以为IIC(Inter－Integrated Circuit，内部集成电路)模块。
在一些实施例中，如图2所示，该数据处理装置10'还可以包括发送模块160。发送模块160分别电连接至叠加器130和显示面板40。发送模块160被配置为将从叠加器130接收的目标图像信息发送到显示面板40。这样，可以使得显示面板40显示叠加后的目标图像信息。例如，该发送模块为V-by-One(简称为VBO)发送模块。
在一些实施例中，如图2所示，该数据处理装置10'还可以包括总线模块170。该总线模块170分别与存储器20、第一写控制器101、第二写控制器102、第一读控制器111和第二读控制器112电连接。即，第一写控制器101、第二写控制器102、第一读控制器111和第二读控制器112分别通过总线模块170电连接至存储器20。例如，该总线模块170可以为AXI(Advanced eXtensible Interface，先进可扩展接口)总线仲裁模块。
至此，提供了根据本公开另一些实施例的数据处理装置。该数据处理装置(例如FPGA器件)可以使得显示装置在显示期间实现人机交互界面信息与视频图像的叠加显示，在非显示期间解除人机交互界面信息对存储器的占用，并且可以实现人机交互界面信息与视频图像数据的多次动态同步，从而在不影响人机交互界面信息的显示的情况下降低数据处理装置在非显示期间的功耗。
在一些实施例中，如图2所示，该显示装置还包括控制单元30。该控制单元30分别电连接至第二接收模块152和第三接收模块153。该控制单元30被配置为向数据处理装置10'输出人机交互界面信息、开启命令和关闭命令。例如，该控制单元为SOC芯片。
在一些实施例中，如图2所示，该显示装置还包括存储器20。存储器20电连接至总线模块170。存储器20被配置为存储人机交互界面信息和视频图像数据。在一些实施例中，该存储器为内存储器。例如，该内存储器为的第三代双倍速率同步动态随机存储器(Double Data Rate 3，简称DDR3)。
在一些实施例中，如图2所示，该显示装置还包括显示面板40。该显示面板40被配置为显示目标图像信息。
在一些实施例中，该显示装置为用于监视器的显示装置。
图3是示出根据本公开一些实施例的相关信号的时序控制图。图4是示出根据本公开另一些实施例的相关信号的时序控制图。下面结合图2至图4详细描述根据本公开一些实施例的数据处理装置的工作过程。
首先，接收视频图像数据，将视频图像数据写入存储器以及从存储器读出。如图2所示，通过第一接收模块151将串行的视频图像数据转换成并行的具有标准时序的视频图像数据，并使用随路时钟信信号通过第一写控制器101将视频图像数据写入存储器20。将第一时序产生器121产生的第一时序控制信号(该第一时序控制信号为本地时钟信号)传输到第一读控制器111，使得第一读控制器111从存储器20读取视频图像数据。
例如，上述方法可以采用标准4K时序。具体参数为：HTT:4400；VTT:2250；HAC:3840；VAC:2160；HFP:176；VFP:8；HSW:88；VSW:10；HBP:296；VBP:72。
这里，HTT表示在水平方向上每一行像素时钟的总数；HAC为在水平方向上每一行有效像素时钟的个数，即有效数据选通信号DE的高电平期间的时钟个数；HFP为在水平方向上的前沿时钟的个数，即DE信号下降沿到行同步信号HSYNC(表示扫描一行的开始)的上升沿之间的时钟个数；HSW为在水平方向上的HSYNC信号的高电平期间的时钟个数；HBP为在水平方向上的后沿时钟的个数，即HSYNC信号的下降沿到DE信号的上升沿之间的时钟个数；VTT为在垂直方向上的每一帧图像的总的行数；VAC为在垂直方向上的每一帧图像的有效行数；VFP为在垂直方向上的前沿行数，即每一帧图像最后一个DE信号的下降沿到帧同步信号VSYNC(表示扫描 一帧图像的开始)的上升沿之间的行数；VSW为在垂直方向上的VSYNC信号的高电平期间的行数；VBP为在垂直方向上的后沿行数，即VSYNC信号的下降沿到每一帧图像第一个DE信号的上升沿之间的行数。
接下来，人机交互界面命令解析，以及产生相关时序信号。通常情况下人机交互界面在绝大多数时间内是不需要显示的，本步骤可以使得人机交互界面按需对存储器20进行访问，即人机交互界面不需要显示时解除对存储器的占用，需要显示时恢复对存储器的占用并与视频图像数据进行动态同步。通过这种方式降低人机交互界面对存储器的占用，从而降低了数据处理装置的功耗。
控制单元30通过第三接收模块153发送人机交互界面是否显示的命令(即开启命令或关闭命令)。第三接收模块153开始工作的时刻为用户操作界面的时刻、人机交互界面开始工作的时刻为控制单元30上电初始化完成的时刻、第一时序产生器开始工作的时刻为数据处理装置初始化完成的时刻，这三个时刻不存在固定的时间关系。因此，第一计数器141在接收到开启命令(即ON命令)后开始对人机交互界面信息的帧同步信号进行向上计数(即从小到大计数，例如从0开始计数)，例如，计数到15停止计数。第一计数器141在接收到关闭命令(即OFF命令)后开始对人机交互界面信息的帧同步信号进行向下计数(即从大到小计数，例如从15开始计数)，计数到0停止计数。第二计数器142在接收到开启命令后，开始对第一时序产生器121的第一时序控制信号的帧同步信号进行向上计数(即从小到大计数，例如从0开始计数)，计数到15停止计数。第二计数器142在接收到关闭命令后开始对第一时序控制信号的帧同步信号进行向下计数(即从大到小计数，例如从15开始计数)，计数到0停止计数。请参见图3所示。
上述步骤区分以下两种情况：
(1)人机交互界面通常由用户发出命令显示。人机交互命令由不显示命令变为显示命令，即由关闭命令变为开启命令。当命令检测模块143检测到开启命令后，第一计数器141开始对人机交互界面信息的帧同步信号进行计数，第二计数器142开始对第一时序产生器121的第一时序控制信号的帧同步信号进行计数。根据第一计数器141和第二计数器142的计数结果，依次启动第二写控制器102、第二时序产生器122和叠加器130。
例如，当第一计数器的第一计数值为1时，启动第二写控制器102，第二写控制器102开始向存储器20内部写入人机交互界面信息的数据，当第一计数值大于1(即 在存储器中写入了完整的一帧人机交互界面图像后)且第二计数器的第二计数值发生变化(这表明第一读控制器111从存储器20读取了一帧视频图像数据)时，同步启动第二时序产生器122和叠加器130。通过启动第二时序产生器122来启动第二读控制器112，从而使得第二读控制器112从存储器20读取人机交互界面图像。这样，被开启的叠加器130可以对由第一读控制器111读取的一帧视频图像和由第二读控制器112读取的一帧人机交互界面图像进行叠加。
例如，利用第一时序控制信号读取视频图像数据所显示的视频图像的分辨率为3840×2160，利用第二时序控制信号读取人机交互界面信息所显示的人机交互界面图像的分辨率为1920×1080。例如，在显示时，人机交互界面图像可以位于视频图像的中间且靠近边缘的位置。
(2)人机交互命令由显示命令变为不显示命令，即由开启命令变为关闭命令。当命令检测模块143检测到关闭命令后，第一计数器141开始对人机交互界面信息的帧同步信号进行计数，第二计数器142开始对第一时序产生器的第一时序控制信号的帧同步信号进行计数。根据第一计数器141和第二计数器142计数结果，依次关闭叠加器130、第二时序产生器122和第二写控制器102。
例如，如图4所示，当第一计数器的第三计数值为第二预设值(例如，第二预设值＝14)时，关闭第二写控制器102，使得第二写控制器102停止向存储器20的内部写入人机交互界面图像数据；当第二计数器的第四计数值为第三预设值(例如，第三预设值为14)时，关闭第二时序产生器122和叠加器130。由于关闭了第二时序产生器122，因此第二时序产生器122不再向第二读控制器112发送第二时序控制信号，从而使得第二读控制器112不再从存储器20读取人机交互界面信息。另外，叠加器130被关闭后不再进行叠加处理。
接下来，发送模块160将叠加后的目标图像信息发送给显示面板40以进行显示。
至此，提供了根据本公开一些实施例的数据处理装置的工作过程。通过该工作过程，数据处理装置可以使得显示装置在显示期间实现人机交互界面信息与视频图像的叠加显示，在非显示期间解除人机交互界面信息对存储器的占用，并且可以实现人机交互界面信息与视频图像数据的多次动态同步，从而在不影响人机交互界面信息的显示的情况下降低数据处理装置在非显示期间的功耗。
图5是示出根据本公开一个实施例的用于数据处理装置的控制方法的流程图。如图5所示，该控制方法包括步骤502至S510。
在步骤S502，利用命令控制器在接收到开启命令后控制写控制器将人机交互界面信息写入存储器和启动叠加器。
在步骤S504，利用第一读控制器从存储器读取视频图像数据。
在步骤S506，利用第二读控制器从存储器读取所述人机交互界面信息。
在步骤S508，利用叠加器对从第一读控制器接收的视频图像数据和从第二读控制器接收的人机交互界面信息进行叠加处理以得到目标图像信息。
在一些实施例中，步骤S508包括：利用叠加器在对视频图像数据和人机交互界面信息进行叠加处理的过程中，将视频图像数据延迟预定时间以使得视频图像数据的时间与人机交互界面信息的时间对齐，并将延迟后的视频图像数据和人机交互界面信息进行叠加。
在步骤S510，利用命令控制器在接收到关闭命令后控制写控制器停止将人机交互界面信息写入所述存储器和关闭叠加器。
至此，提供了根据本公开一些实施例的用于数据处理装置的控制方法。该控制方法可以使得显示装置在显示期间实现人机交互界面信息与视频图像的叠加显示，在非显示期间解除人机交互界面信息对存储器的占用，从而在不影响人机交互界面信息的显示的情况下降低数据处理装置(例如，FPGA器件)在非显示期间的功耗。

在一些实施例中，步骤S502包括：利用命令检测模块接收开启命令并输出启动信号；利用第一计数器响应于启动信号对人机交互界面信息的帧同步信号按照第一计数方式计数，并根据第一计数值控制写控制器将人机交互界面信息写入存储器；和利用第二计数器响应于启动信号对第一时序控制信号的帧同步信号按照第二计数方式计数，并根据第二计数值和从第一计数器接收的第一计数值开启第二时序产生器和叠加器。
在一些实施例中，步骤S510包括：利用命令检测模块接收关闭命令并输出关闭信号；利用第一计数器响应于关闭信号对人机交互界面信息的帧同步信号按照第三计 数方式计数，并根据第三计数值控制写控制器停止将人机交互界面信息写入存储器；和利用第二计数器响应于关闭信号对第一时序控制信号的帧同步信号按照第四计数方式计数，并根据第四计数值关闭第二时序产生器和叠加器。
在一些实施例中，控制写控制器将人机交互界面信息写入存储器的步骤包括：利用第一写控制器将视频图像数据写入存储器；和利用第二写控制器将人机交互界面信息写入存储器。
在一些实施例中，利用第一计数器在第一计数值为第一预设值时开启第二写控制器，以及在第三计数值为第二预设值时关闭第二写控制器；利用第二计数器在第一计数值大于第一预设值且第二计数值发生变化时开启第二时序产生器和叠加器，以及在第四计数值为第三预设值时关闭第二时序产生器和叠加器。

    利用第二计数器响应于所述启动信号对所述第一时序控制信号的帧同步信号按照第二计数方式计数，并根据第二计数值和从所述第一计数器接收的所述第一计数值开启所述第二时序产生器和所述叠加器。
  15. 根据权利要求14所述的控制方法，其中，利用所述命令控制器在接收到关闭命令后控制所述写控制器停止将所述人机交互界面信息写入所述存储器和关闭所述叠加器的步骤包括：
    利用所述命令检测模块接收所述关闭命令并输出关闭信号；
    利用所述第一计数器响应于所述关闭信号对所述人机交互界面信息的帧同步信号按照第三计数方式计数，并根据第三计数值控制所述写控制器停止将所述人机交互界面信息写入所述存储器；和
    利用所述第二计数器响应于所述关闭信号对所述第一时序控制信号的帧同步信号按照第四计数方式计数，并根据第四计数值关闭所述第二时序产生器和所述叠加器。
  16. 根据权利要求12所述的控制方法，其中，利用所述叠加器对所述视频图像数据和所述人机交互界面信息进行叠加处理的步骤包括：
    利用所述叠加器在对所述视频图像数据和所述人机交互界面信息进行叠加处理的过程中，将所述视频图像数据延迟预定时间以使得所述视频图像数据的时间与所述人机交互界面信息的时间对齐，并将延迟后的视频图像数据和所述人机交互界面信息进行叠加。
  17. 根据权利要求15所述的控制方法，其中，控制所述写控制器将所述人机交互界面信息写入存储器的步骤包括：
    利用第一写控制器将视频图像数据写入所述存储器；和
    利用第二写控制器将人机交互界面信息写入所述存储器。
  18. 根据权利要求17所述的控制方法，其中，
    利用所述第一计数器在所述第一计数值为第一预设值时开启所述第二写控制器，以及在所述第三计数值为第二预设值时关闭所述第二写控制器；
    利用所述第二计数器在所述第一计数值大于所述第一预设值且所述第二计数值发生变化时开启所述第二时序产生器和所述叠加器，以及在所述第四计数值为第三预设值时关闭所述第二时序产生器和所述叠加器。
  19. 一种数据处理装置，包括：
    存储器；以及
    耦接至所述存储器的处理器，所述处理器被配置为基于存储在所述存储器的指令执行如权利要求12至18任意一项所述的方法。
  20. 一种非瞬时性计算机可读存储介质，其上存储有计算机程序指令，该计算机程序指令被处理器执行时实现如权利要求12至18任意一项所述的方法。
