数据交换网络结构常用于各种数据路由以及数据交换的场景中。在矢量处理中,由于要并行处理多个数据,所以通常会涉及到各个数据之间的交换、重排等操作。一般这种操作都是通过一个专用的数据交换结构实现的,这种专用的数据交换结构是一种网络结构(即数据交换网络结构),通过该结构可以实现数据的交换、重排等操作。
但是,目前现有的各种数据交换网络结构,例如CrossBar网络、Clos网络和Omega网络,虽然灵活性较高,但是都比较复杂,不太适合用硬件实现。

在一种可行的实施方式中,上述数据处理方法还包括:将所述第二级输出数据输入第三级网络交换结构,得到第三级输出数据;所述第三级网络交换结构包含N组第三选择单元,每组所述第三选择单元包含M个第三选择单元;所述第三级网络交换结构中第P(b)个第三选择单元的输入数据包括第二级输出数据中第P组中的第b个第三数据和第二级输出数据第b组中的任一第三数据,所述第P(b)个第三选择单元的输出数据为该第三选择单元输入数据中的一个,所述第P(b)个第三选择单元为第三级网络交换结构第P组中的第b个第三选择单元,所述第三级输出数据包括所述第三级网络交换结构中每个第三选择单元的输出数据,所述P为小于或等于N的正整数,b为小于或等于M的正整数。
其中,可参见图3,图3为本申请实施例中另一种数据交换网络300的结构示意图。如图3所示,数据交换网络300除包含数据交换网路200中的第一级网络交换结构和第二级网络交换结构外,还包含如图3所示的第三级网络交换结构,该第三级网络交换结构中所包含的第三选择单元的数量和组数与第一、第二级网络交换结构中的选择单元相同,此处不再赘述。应当理解,图3所示的数据交换网络可以是软件执行单元或硬件执行单元,本申请对此不做具体限定。
具体地,第三级网络交换结构可以包含以下功能:
(1)数据直通:第三级网络交换结构中的N*M个第三选择单元的输入和 输出数据分别等于第二级输出数据中的N*M个第三数据,也即是说第三级网络交换结构中的第P(b)个第三选择单元的输入和输出数据分别等于第二级输出数据中的第P(b)个第三数据;其中,第P(b)个第三选择单元指第三级网络结构中第P组中的第b个第三选择单元,第P(b)个第三数据指第二级输出数据中第P组中的第b个第三数据,P为小于或等于N的正整数,b为小于或等于M的正整数。
(2)数据聚拢:确定第三级网络交换结构中的目标组第三选择单元,将该目标组中的第b个第三选择单元的输出数据设置为第二级输出数据第b组中的任一第三数据,即将第二级输出数据中的不同组中的数据聚拢到第三级输出数据的同一组中。在第三级网络交换结构中,除目标组第三选择单元外的其它N-1组第三选择单元中每个第三选择单元的输出数据可以为该每个第三选择单元输入数据中的一个或不输出。可以理解,在一种可能的场景下,当第三级网络交换结构中,除目标组第三选择单元外的其它N-1组第三选择单元中每个第三选择单元的输出数据为空时,第三级输出数据为目标组第三选择单元的M个输出数据;此时,第三级网络交换结构的功能为将第二级输出数据中的M个数据聚拢到目标组第三选择单元中进行输出,此时第三级输出数据为上述聚拢后的M个数据。
(3)除上述两种功能外,还可以根据具体的场景确定第三级网络交换结构中每个第三选择单元的输出数据。
可以看出,本申请实施例中用来进行数据处理的数据交换网络结构还可以包含第三级网络交换结构,该第三级网络交换结构的架构与第一和第二级网络交换结构的架构相同,因而当上述数据交换网络中包含三级网络交换结构时,其结构依然较为简单,便于硬件实现;同时,该第三级网络交换结构用于实现将第二级输出数据中的M个数据聚拢到第三级网络交换结构的同一组中进行输出,因而,当数据交换网络包含上述三级网络交换结构时,可以通过上述三级网络交换结构分别实现不同的功能,进而可以根据不同场景,采用上述三级网络交换结构对输入数据进行不同地处理从而得到相应的输出数据,灵活性强。
在一种可行的实施方式中,所述第E(i)个第一选择单元的输出数据在所述第一级输入数据中的组号与所述M个第一目标数据中第i个第一目标数据的组号相同;所述第F(j)个第二选择单元的输出数据在所述第一级输出数据中的组内编号与所述M个第一目标数据中第j个第一目标数据的组内编号相同;将目标组第三选择单元中第b个第三选择单元的输出数据确定为第二级输出数据第b组中的任一第三数据,所述目标组第三选择单元为所述N组第三选择单元中的一组。
具体地,首先从第一级输入数据中确定M个第一目标数据,通过将第E(i)个第一选择单元的选择信号确定为M个第一目标数据中第i个第一目标数据的组号(如公式(3)所示),即从第E(i)个第一选择单元的输入数据中选择出与M个第一目标数据中第i个第一目标数据的组号相同的第一数据作为第E(i) 个第一选择单元的输出数据;然后将第F(j)个第二选择单元的选择信号确定为M个第一目标数据中第j个第一目标数据的组内编号((如公式(3)所示)),即从第F(j)个第二选择单元的输入数据中选择出与M个第一目标数据中第j个第一目标数据的组内编号相同的数据作为第F(j)个第二选择单元的输出数据;此时,第二级输出数据中每组组内的M个数据相同,最后将目标组第三选择单元中第b个第三选择单元的输出数据设置为第二级输出数据第b组中的任一第三数据,即可M个第一目标数据聚拢到目标组第三选择单元进行输出,此时,第三级输出数据为M个第一目标数据。
选择信号=M(i%N)的组号                  (3)
选择信号=M(j%N)的组内编号        (4)
其中,“%”表示两整数相除的余数;M(i%N)表示M个第一目标数据中的第i%N个数据;公式(3)即表示从第E(i)个第一选择单元的输入数据中选择出与M个第一目标数据中第i%N个第一目标数据的组号相同的第一数据作为第E(i)个第一选择单元的输出数据。同理,公式(4)表示从第F(j)个第二选择单元的输入数据中选择出与M个第一目标数据中第M(j%N)个第一目标数据的组内编号相同的数据作为第F(j)个第二选择单元的输出数据。
可以看出,本申请实施例中,当数据交换网络结构包含三级网络交换结构时,通过对该三级网络交换结构中每级网络交换结构中的选择单元设置不同的选择信号来选择相应的输出数据,从而将第一级输入数据中M个第一目标数据进行抽取,聚拢到在第三级输出数据的同一组中进行输出,从而实现采用上述数据交换网络结构对M个第一目标数据进行抽取的功能。
在一种可行的实施方式中,上述第E(i)个第一选择单元的输出数据在所述第一级输入数据中的组号与第二目标数据在所述第一级输入数据中的组号相同;所述第F(j)个第二选择单元的输出数据在所述第一级输出数据中的组内编号与所述第二目标数据在所述第一级输入数据中的组内编号相同,所述第二目标数据为所述第一级输入数据中的一个。
具体地,可通过图2所示的数据交换网络200对第一级输入数据中的第二目标数据进行广播,具体过程如下:
(1)将第一级网络交换结构中每个第一选择单元的选择信号设为第二目标数据的组号,使得任一第一选择单元的输出数据在第一级输入数据中的组号与第二目标数据在第一级输入数据中的组号相同,即第一级网络交换结构中的每组第一选择单元的输出数据为第二目标数据所在组的M个第一数据,且每组第一选择单元内每个第一选择单元的输出数据在第一级输入数据中的组内编号与该每个第一选择单元的组内编号相同。应当理解,此时第一级输出数据为N组相同的第二数据。
(2)在得到上述N组相同的第一级输出数据后,将该第一级输出数据输入第二级网络交换结构,第二级网络交换结构中第F组中每个第二选择单元的 输入数据为第一级输出数据中的第F组,此时,由于第一级输出数据中所包含的N组第二数据相同,第二级网络交换结构中的各第二选择单元的输入数据相同,即为第二目标数据在第一级输入数据中所在组的M各第一数据。此时,将第二级网络交换结构中每个第二选择单元的选择信号设为第二目标数据的组内编号,即第二级网络交换结构中每个第二选择单元的输出数据为第二目标数据,从第二级网络交换结构输出的第二级输出数据为N*M个第二目标数据。
应该理解,通过上述第一网络交换结构和第二级网络交换结构中各选择单元的信号选择方式,可以将第一级输入数据中的第二目标数据输出到第二级输出数据中的每个位置上,即通过本申请实施例中的网络结构和上述的信号选择方式实现数据广播的功能。
可选地,也可通过图3所示的数据交换网络300对第一级输入数据中的第二目标数据进行广播。在采用数据交换网络300对第二目标数据进行广播时,第一级网络交换结构和第二网络交换结构的选择信号与数据交换网络200中的对应各级网络交换结构的选择信号相同。此时,数据交换网络300中第三级网络交换结构的选择信号设为与每个第三选择单元的组号和组内编号相同,即每个第三选择单元的输入数据和输出数据为在第二级输出数据中的组号和组内编号与该每个第三选择单元的组号和组内编号相同。
可以看出,本申请实施例中,当数据交换网络结构包含两级网络交换结构时,通过对该两级网络交换结构中每级网络交换结构中的选择单元设置不同的选择信号来选择相应的输出数据,从而将第一级输入数据中第二目标数据进行广播,即第二级输出数据中的N*M个第三数据全都为该第二目标数据,从而实现对第二目标数据的广播功能;综上,在本申请的上述实施中,可以通过对数据交换网络中每级网络交换结构中的选择单元设置相应的选择信号来实现数据抽取或数据广播的功能,表明上述数据交换网络的灵活性较好。
在一种可行的实施方式中,根据第三目标数据在所述第一级输入数据中的组号、组内编号、所述第E(i)个第一选择单元的组号确定所述第E(i)个第一选择单元的输出数据在所述第一级输入数据中的组号;根据所述第三目标数据在所述第一级输入数据中的组内编号和所述第F(j)个第二选择单元的组内编号确定所述第F(j)个第二选择单元的输出数据在所述第一级输出数据中的组内编号,所述第三目标数据为所述第一级输入数据中的一个。
具体地,可通过图2所示的数据交换网络200对第一级输入数据中的第三目标数据进行旋转,具体过程如下:
(1)上述根据第三目标数据在第一级输入数据中的组号、组内编号、第E(i)个第一选择单元的组号确定第E(i)个第一选择单元的输出数据在第一级输入数据中的组号,可以包括:根据公式(1)确定第E(i)个第一选择单元的输出数据在所述第一级输入数据中的组号。
(2)上述根据第三目标数据在第一级输入数据中的组内编号和第F(j)个第二选择单元的组内编号确定第F(j)个第二选择单元的输出数据在第一级输 出数据中的组内编号,可以包括:根据公式(2)确定所述第F(j)个第二选择单元的输出数据在所述第一级输出数据中的组内编号。
组号=(E+X)%N+i/a           (1)
组内编号=(j+a)%N           (2)
其中,X为第三目标数据在第一级输入数据中的组号,a为第三目标数据在第一级输入数据中的组内编号,“%”表示取两个整数相除后的余数,“/”表示取两个整数相除后所得商的整数部分。
应该理解,通过上述第一网络交换结构和第二级网络交换结构中各选择单元的信号选择方式,可以将第一级输入数据中的第三目标数据输出到第二级输出数据的第1组中的第1个数据,即通过本申请实施例中的网络结构和上述的信号选择方式实现数据广播的旋转功能。
可选地,也可通过图3所示的数据交换网络300对第一级输入数据中的第三目标数据进行广播。在采用数据交换网络300对第三目标数据进行广播时,第一级网络交换结构和第二网络交换结构的选择信号与数据交换网络200中的对应各级网络交换结构的选择信号相同。此时,数据交换网络300中第三级网络交换结构的选择信号设为与每个第三选择单元的组号和组内编号相同,即每个第三选择单元的输入数据和输出数据为在第二级输出数据中的组号和组内编号与该每个第三选择单元的组号和组内编号相同。
可以看出,本申请实施例中,当数据交换网络结构包含两级网络交换结构时,具体可通过根据上述公式(1)和公式(2)对该两级网络交换结构中每级网络交换结构中的选择单元设置不同的选择信号来选择相应的输出数据,从而将第一级输入数据中第三目标数据进行旋转,即将第一级输入数据中的第三目标数据输出到第二级输出数据中的相应位置,从而实现对第三目标数据的旋转功能;综上,可以通过对数据交换网络中每级网络交换结构中的选择单元设置相应的选择信号来实现数据抽取,或数据广播,或数据旋转的功能,表明上述数据交换网络的灵活性较好。
