[0028] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0029] The processing unit can write data into the static random access memory cell, and can also read data from the static random access memory cell. Thus, the static random access memory cell can correspond to a write path and a read path. Via the write path, the processing unit can write data into the static random access memory cell. Via the read path, the processing unit can read data from the static random access memory cell. The write path and the read path can be implemented by a large-scale cross switch. The structure of the write path and the read path is basically the same.

[0030] In some embodiments, one or more processing units may access static random access memory cells via I first ports. There may also be multiple static random access memory cells. Multiple static random access memory cells may include J storage areas. J storage areas may correspond to J second ports. If the bit width of the data to be accessed is W and a read path or a write path is implemented by a cross switch, the total number of windings may be IxJxW. If I, J, and W are large, the total number of windings determined by multiplying the three will be very large, making it difficult to converge the timing and area of ​​the chip. In addition, a large number of windings will cause winding congestion, making it more difficult to converge the timing and area. In addition, a logical multiplexer of J to 1 or a logical multiplexer of I to 1 needs to be implemented at the port, and the physical implementation is very difficult. If the read path and the write path use the same winding method to implement a substantially identical structure, the difficulty of winding will be further increased. I may be an integer greater than 1. J may be an integer greater than 1. W may be an integer greater than 1, and the unit of W is bits or bits. For example, I=J=16, and W equals 32 bits.

[0031] Therefore, in order to reduce routing congestion and reduce chip timing and area convergence risks, the present disclosure provides a data transmission device, which will be described below.

[0032] Figure 1 is a schematic diagram of the system architecture of an exemplary chip to which a data transmission device can be applied according to an embodiment of the present disclosure. It should be noted that: Figure 1 What is shown is merely an example of a system architecture to which the embodiments of the present disclosure can be applied, in order to help those skilled in the art understand the technical content of the present disclosure, but it does not mean that the embodiments of the present disclosure cannot be used in other devices, systems, environments or scenarios.

[0033] like Figure 1 As shown, the chip 10 may include a plurality of first ports, a data transmission device 100, and a plurality of second ports. The plurality of first ports may include a first port c100, ... a first port c115. The first port may be a port of a processing unit. The plurality of second ports may include a second port b100, ... a second port b115. The second port may be a port of a storage unit. The storage unit may be, for example, the above-mentioned static random access memory unit.

[0034] For example, the processing unit of the chip 10 may write data into the storage unit via the first port c100, the data transmission device 100 and the second port b100 in sequence. For another example, the processing unit of the chip 10 may read data from the storage unit via the second port b100, the data transmission device 100 and the first port c100 in sequence.

[0035] It can be understood that the above describes the system architecture of the present disclosure, and the following will describe the device of the present disclosure.

[0036] Figure 2 is a schematic block diagram of a data transmission device according to an embodiment of the present disclosure.

[0037] like Figure 2 As shown, the device 201 may include a plurality of first routing units 210 and a plurality of second routing units 220. It can be understood that, via the device 201, the processing unit may write data into the storage unit.

[0038] In the embodiment of the present disclosure, the first routing unit 210 may be configured to: receive first data provided via at least one of the K first ports. The first data may include data to be written into the storage unit. The first port may be one of the first ports c101, ..., c116 described above.

[0039] In the embodiment of the present disclosure, the K first ports are respectively from K different first port groups. K is an integer greater than 1. For example, taking K=2 as an example, the first routing unit can receive the first data provided via at least one of a first port of the first first port group and a first port of the second first port group.

[0040] In the embodiment of the present disclosure, the first routing unit 210 may also be configured to provide the first data to at least one of the plurality of second routing units of the second routing unit group. For example, taking two second routing unit groups as an example, the first routing unit may provide the received first data to one or more second routing units in the first second routing group.

[0041] In the embodiment of the present disclosure, the second routing unit 220 may be configured to provide the received first data to the second port of the storage unit. For example, the storage unit may be the static random access memory unit described above. Each second routing unit may provide the second data to one or more second ports.

[0042] Through the embodiments of the present disclosure, the K first ports are respectively from K different first port groups, which can reduce the number of windings between the first routing unit and the first port, and can alleviate winding congestion. The first routing unit provides the first data to a second routing unit group. The number of windings between the first routing unit and the second routing unit is also small, which can also alleviate congestion. The second routing unit provides the first data to one or more second ports, which can effectively reduce the number of windings and fully alleviate winding congestion. While ensuring data transmission efficiency, the number of windings can be fully reduced to save chip area overhead.

[0043] It can be understood that the above describes the device of the present disclosure, and the device of the present disclosure will be further described below.

[0050] It can be understood that the above describes multiple hardware unit groups, and some methods of data transmission will be described below.

The first routing unit 3115 may receive the first data provided via at least one of the first port c303, the first port c307, the first port c311, and the first port c315. Thus, the third first routing unit group may receive the first data provided from the first port c300 to the first port c315.

[0058] Through the embodiments of the present disclosure, the first routing unit group can receive data provided by all first ports. When multiple first routing units in the group receive data provided by different first ports respectively, the number of windings near the first ports can be reduced, which helps to reduce chip area overhead. It is also possible to receive first data provided by multiple first ports through one first routing unit group, thereby improving data transmission efficiency.
