Data transmission apparatuses, data processing systems and methods

A data processing method, comprising:

• in response to receiving a read request for data in at least one memory (200) in a plurality of memories (200), obtaining the data from the at least one memory (200) by a data transmission apparatus (100), wherein the data transmission apparatus (100), comprises:
• a plurality of first ports (101), coupled to a processing unit;
• a plurality of second ports (102), coupled to a plurality of memories (200);
• and a plurality of data channels (103), disposed among the first ports (101) and the second ports (102) to form an interleaving network having a plurality of layers, and configured to transmit data among the processing unit and the plurality of memories (200), wherein, the plurality of layers are hierarchically connected, one of two ends of the plurality of layers hierarchically connected is connected to the plurality of first ports (101), another of two ends of the plurality of layers hierarchically connected is connected to the plurality of plurality of second ports (102), each layer comprises at least one interleaving sub-network (1031), and a number of a plurality of interleaving sub-networks (1031) in each of the plurality of layers of the interleaving network increases or decreases from the first ports (101) to the second ports (102).

A data processing system (300), comprising:

• a processing unit;
• a data transmission apparatus (100), comprising:
