为了说明本申请所述的技术方案,下面通过具体实施例来进行说明。
图1是本申请实施例提供的一种基于多核处理器的解码方法的实现流程示意图,如图所示该方法可以包括以下步骤:
步骤S101,从所述多核处理器中选取一个内核作为主核,并通过所述主核获取待解码图像。
在本申请实施例中,可以定义所述多核处理器中的一个内核为主核,实际应用中,可以选择任意一个内核作为主核,在确定主核后,通过主核从摄像头或预设的存储空间中获取待解码图像,在进行扫码时,通常会调用摄像头采集待解码图像,因此可以从摄像头获取待解码图像,另外,由于摄像头在采集待解码图像后,可以存储在预设的存储空间,因此,主核也可以从预设的存储空间获取待解码图像。
步骤S102,从所述多核处理器中选取N个内核作为解码内核,其中,N小于或等于所述多核处理器的内核数量。
在本申请实施例中,可以从所述多核处理器中选取一部分内核用于运行解码任务,也可以将所述多核处理器中的全部内核用于运行解码任务,例如,4核处理器可以将全部内核运行解码任务,8核处理器中可以选择其中4个或6个内核用于运行解码任务。为了方便区别不同的内核,本申请实施例将运行解码任务的内核记为解码内核。
步骤S103,通过N个解码内核同时对所述待解码图像进行解码。
在本申请实施例中,用于运行解码任务的解码内核可以同时对待解码图像进行解码。在实际应用中,系统中存储了多个编码码制,选取的N个解码内核可以依次选取编码码制对待解码图像进行解码。例如,系统中存储了编码码制A1、A2、A3、A4、A5、A6、A7、A8、A9、A10。N=4,4个解码内核按照次序分别选取编码码制,用于对待解码图像进行解码,第一个解码内核选取A1,基于A1对待解码图像进行解码,第二个解码内核选取A2,基于A2对待解码图像进行解码,第三个解码内核选取A3,基于A3对待解码图像进行解码,第四个解码内核选取A4,基于A4对待解码图像进行解码。在4个解码内核中,任意一个通过选取的编码码制对待解码图像解码失败后,继续从编码码制的队列中选取未被选取的一个编码码制继续对待解码图像进行解码。直到其中一个解码内核通过选取的编码码制对待解码图像解码成功,这样就生成解码结果;或者直到将所有的编码码制选取完毕,依然未对待解码图像解码成功,这样就表示解码失败。
本申请实施例从所述多核处理器中选取一个内核作为主核,并通过所述主核获取待解码图像,从所述多核处理器中选取N个内核作为解码内核,其中,N小于或等于所述多核处理器的内核数量,通过N个解码内核同时对所述待解码图像进行解码。由于,通过多个内核同时对待解码图像进行解码,因此可以提高解码速度。
图2是本申请实施例提供的另一种基于多核处理器的解码方法的实现流程示意图,如图所示,该方法可以包括以下步骤:
步骤S201,从所述多核处理器中选取一个内核作为主核,并通过所述主核获取待解码图像。
该步骤与步骤S101内容一致,具体可参照步骤S101的描述,在此不再赘述。
步骤S202,从所述多核处理器中选取N个内核作为解码内核,其中,N小于或等于所述多核处理器的内核数量。
在本申请实施例中,以N等于所述多核处理器的内核数量为例,那么选取的解码内核包括主核。例如,多核处理器为4核处理器,从其中选取一个内核作为主核,4个内核均作为解码内核。
步骤S203,获取预先存储的多个编码码制,并将多个编码码制划分为N组,其中,每个解码内核对应一组编码码值。
在本申请实施例中,可以获取系统中预先存储的多个编码码制,并将多个编码码制划分为N组,可以对所述多个解码码制按照历史使用频率从高到底进行排序;将排序后的多个解码码制划分为N组,其中,第i组解码码制的排序序号为i+aN,a为大于或等于0的自然数,i∈[1,N]。
作为举例,按照历史使用频率从高到低对系统中存储的多个编码码制进行排序:A1,A2,A3,A4,B1,B2,B3,B4,C1,C2,C3,C4,D1,D2,D3,D4,E1......。
第一组为排序序号1+4a的编码码制,即第1个(A1)、第5个(B1)、第9个(C1)、……。
第二组为排序序号2+4a的编码码制,即第2个(A2)、第6个(B2)、第10个(C2)、……。
第三组为排序序号3+4a的编码码制,即第3个(A3)、第7个(B3)、第11个(C3)、……。
第四组为排序序号4+4a的编码码制,即第4个(A4)、第8个(B4)、第12个(C4)、……。
分组后,每个解码内核对应一组编码码制。
步骤S204,N个解码内核同时基于各自对应的排序后的编码码值对所述待解码图像进行解码。
在本申请实施例中,在进行解码前,也可以对每个解码内核对应的编码码值按照历史使用频率从高到低进行排序。
需要说明,在对所述编码码制进行排序时,可以先找历史使用频率,也可以按照历史解码成功的次数。
在多个解码内核同时对待解码图像进行解码时,每个解码内核都是基于各自对应的一组编码码制进行解码,其中一个解码内核在基于对应的每一个编码码制对待解码图像进行解码,要么成功,要么失败,成功则提前结束整个解码任务;失败接着按照顺序选取下一个编码码制对待解码图像进行解码。
在实际应用中,需要多个内核之间相互知晓是否有其他内核解码成功,在有其他内核解码成功时,停止解码任务,如步骤S205至步骤S208的描述。
步骤S205,若所述主核对所述待解码图像解码成功,则所述主核停止解码,并向所述主核之外的解码内核发送停止解码的指令。
步骤S206,若主核之外的解码内核对所述待解码图像解码成功,则当前解码成功的解码内核停止解码,并向所述主核发送解码成功的指令。
步骤S207,所述主核在接收到解码成功的指令后,向所述主核之外解码内核发送停止解码的指令。
步骤S208,若所述主核之外的解码内核通过每一个对应的解码码制均对所述待解码图像解码失败,则向所述主核发送解码失败的指令。
在本申请实施例中,预先选取的主核通过对应的编码码制对所述待解码图像解码成功后,停止解码,并通知所述主核之外的解码内核停止解码,这样,所有的内核均停止解码,当前解码任务成功。
主核之外的解码内核基于对应的解码码制对所述待解码图像解码成功后,停止解码,并通过主核解码成功,主核向的其他解码内核(主核和解码成功的解码内核之外的解码内核)发送停止解码的指令。
如果所有的解码内核均未接收到解码成功或者停止解码的指令,则需要按照顺序依次选取各自对应的编码码制对所述待解码图像进行解码,直到全部解码失败或者通过一个编码码制对所述待解码图像解码成功。若是全部解码失败,需要通知主核解码失败。
图3是本申请实施例提供的另一种基于多核处理器的解码方法的实现流程示意图,如图所示,该方法可以包括以下步骤:
步骤S301,从所述多核处理器中选取一个内核作为主核,并通过所述主核获取待解码图像。
该步骤与步骤S101内容一致,具体可参照步骤S101的描述,在此不再赘述。
步骤S302,从所述多核处理器中选取N个内核作为解码内核,其中,N小于或等于所述多核处理器的内核数量。
在本申请实施例中,以N小于所述多核处理器的内核数量为例,且选取的解码内核不包括主核。例如,多核处理器为4核处理器,从其中选取一个内核作为主核,另外3个内核均作为解码内核。
步骤S303,获取预先存储的多个编码码制,并将多个编码码制划分为N组,其中,每个解码内核对应一组编码码值。
步骤S304,对每个解码内核对应的编码码值按照历史使用频率从高到低进行排序。
步骤S305,N个解码内核同时基于各自对应的排序后的编码码值对所述待解码图像进行解码。
在本申请实施例中,可以将预先存储的多个编码码制划分为3组,每一个解码内核对应一组编码码制。每一组编码码制可以根据历史使用频率或者历史解码成功次数进行排序。3个解码内核同时运行解码任务,其中每一个解码内核都是基于各自对应的编码码制对所述待解码图像进行解码,当然,与图2所示实施例相同,也需要按照顺序依次选取各自对应的编码码制对待解码图像进行解码。
步骤S306,若任意一个解码内核对所述待解码图像解码成功,则当前解码成功的解码内核停止解码,并向所述主核发送解码成功的指令。
步骤S307,所述主核在接收到解码成功的指令后,向所述解码内核发送停止解码的指令。
步骤S308,若所述解码内核通过每一个对应的解码码制均对所述待解码图像解码失败,则向所述主核发送解码失败的指令。
在本申请实施例中,由于主核不参与基于编码码制解码的过程,任意的解码内核在对所述待解码图像解码成功后,则当前解码成功的解码内核停止解码,并向所述主核发送解码成功的指令,主核在接收到解码成功的指令后,向所有解码内核或者当前解码成功的其它解码内核发送停止解码的指令。
当然,若所述解码内核通过每一个对应的解码码制均对所述待解码图像解码失败,则向所述主核发送解码失败的指令。
应理解,上述实施例中各步骤的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
