At present, in a data transmission system including a plurality of communication modules, it is common to provide a separate physical line for each two communication modules to realize data transmission between the communication modules. It is common to provide separate physical lines for each two communication modules to enable data transmission between the communication modules. However, this solution requires a large number of physical lines, and each communication module needs to handle data transmission tasks of a plurality of physical lines, resulting in low data transmission efficiency and high cost.
In order to solve the foregoing technical problem, embodiments of the present application provide a data transmission system, a method, an apparatus, an electronic device, and a storage medium. The data transmission system comprises a plurality of communication modules, a clockwise ring line and a counterclockwise ring line, wherein the clockwise ring line and the counterclockwise ring line are connected in series with the communication modules; the communication module comprises a source communication module and a destination communication module, the source communication module comprises a first source communication module and a second source communication module, and the destination communication module comprises a first destination communication module and a second destination communication module; the first source communication module is configured to broadcast data of the first source communication module to the first destination communication module in a clockwise direction through the clockwise ring line; the second source communication module is configured to broadcast the data of the first source communication module to the second destination communication module in a clockwise direction through the counterclockwise ring line.

The first embodiment is as follows:
fig. 1 shows a schematic diagram of a data transmission system provided in an embodiment of the present application. The details are as follows:
the data transmission system includes a plurality of communication modules, and a clockwise ring line and a counterclockwise ring line connecting the respective communication modules in series.
In one embodiment, the data transmission system is a multichip interconnection system, and the communication module is a Die. Die refers to a Die before the chip is packaged, and is a small piece (Die) cut from a silicon Wafer (Wafer) by laser, and each Die is an independent functional chip. In the embodiment of the present application, a plurality of independent functional chips Die are packaged as a unit, so as to obtain a multi-chip interconnection system.
In the embodiment of the application, the data transmission system envelopes P0 to P (n-1) include n communication modules, where n is a positive integer greater than or equal to 3. Illustratively, n may be equal to 8, i.e. 8 communication modules P0 to P7 may be included in the data transmission system.
Clockwise annular circuit is the annular circuit that data transmission direction is clockwise in this application embodiment, and anticlockwise annular circuit is the annular circuit that data transmission direction is anticlockwise, and the annular circuit can establish ties n communication module for end to end's form in proper order. The clockwise circular line and the anticlockwise circular line are parallel to each other and opposite in direction. The n communication modules are sequentially connected in series through the clockwise annular circuit and the anticlockwise annular circuit, so that each communication module is provided with two outlets for outputting data and two inlets for inputting data, which respectively correspond to different clockwise directions, namely, two paths in different directions can be communicated between any two communication modules, and data transmission is realized.
The communication module comprises a source communication module and a destination communication module, the source communication module comprises a first source communication module and a second source communication module, and the destination communication module comprises a first destination communication module and a second destination communication module.
In the embodiment of the application, the source communication module is a communication module which needs to send data, and the destination communication module is a communication module which needs to receive the data of the corresponding source communication module. Specifically, the destination communication module corresponding to each source communication module comprises at least two communication modules with consecutive numbers, so that the data of the source communication module can broadcast one data to the at least two communication modules at one time through a clockwise ring line or a counterclockwise ring line.
In the embodiment of the present application, the data transmission system can have two or more communication modules that need to send data at the same time, and specifically may include a first source communication module and a second source communication module. Correspondingly, the destination communication module comprises a first destination communication module and a second destination communication module.
The first source communication module is configured to broadcast the data of the first source communication module to the first destination communication module in a clockwise direction through the clockwise ring line.
The second source communication module is configured to broadcast data of the second source communication module to the second destination communication module in a counterclockwise direction through the counterclockwise loop line.
Exemplarily, a first source communication module is a communication module P0, and corresponding first destination communication modules are P1-P7; the second source communication module is a communication module P7, and the corresponding second destination communication modules are P0-P6. If only one ring line (for example, a clockwise ring line) exists between P0 to P7, P0 sequentially transfers data to the data streams corresponding to P1 to P7 as follows: p0 → P1 → P2 → P3 → P4 → P5 → P6 → P7, the communication module which needs to occupy the data buffer space (i.e. the communication module which needs to open the resource to receive the data transmitted by other communication modules) includes P1-P7, which can be represented by binary one-hot code: mask0=11111110, wherein the occupation statuses of the communication modules P0 to P7 are represented in order from the lowest bit to the highest bit, "1" represents occupied and "0" represents unoccupied. The second source communication module P7 needs to transmit the data of P7 to P0 to P6, and only a single clockwise ring line is needed, so that the data transmitted by P7 to P0 to P6 in sequence is transmitted as follows: p7 → P0 → P1 → P2 → P3 → P4 → P5 → P6, the communication modules that need the occupied data buffer space are P0 to P6, and the above-mentioned one-hot coding is applied: mask1=11111110. When the above two transmission tasks exist simultaneously, the total occupation situation of the communication module in the data transmission system can be expressed as: mask _ total = mask0| mask1=11111111 (where "|" represents "or" operator "), so that 8 communication modules constitute a data stream receiving loop, which may cause a phenomenon that cache resources of the respective communication modules are all fully occupied at the same time and further data transfer cannot be performed, resulting in a line deadlock.
In the embodiment of the present application, because the data transmission system has the two ring lines in different directions, the first source communication module and the second source communication module respectively transmit the following data in the following manner:
in this embodiment of the present application, the first source communication module is specifically a source communication module that determines, according to the number of the first destination communication module, that the target transmission direction is clockwise; the second source communication module determines that the target transmission direction is the counterclockwise direction according to the number of the second destination communication module.
As shown in fig. 2, the first source communication module P0 can sequentially transmit the data of P0 in the clockwise direction P0 → P1 → P2 → P3 → P4 → P5 → P6 → P7 through the above clockwise ring line, and for P1 to P6, that is, destinations of the data and forwarding nodes for forwarding the data, P1 to P7 can sequentially receive the data of P0, so that the data broadcast of P0 is realized through the clockwise ring line, and the efficient transmission of the data is realized.
The second source communication module P7 can sequentially transmit the data of P7 in the counterclockwise direction P7 → P6 → P5 → P4 → P3 → P2 → P1 → P0 through the above counterclockwise ring line, and for P6 to P1, that is, the destination of the data, and also the forwarding node that forwards the data, P6 to P0 can all sequentially receive the data of P7, thereby realizing the data broadcast of P7 through the counterclockwise ring line, and realizing the efficient transmission of the data.
It can be seen from the above examples that, through the ring line, the data of one source communication module can be broadcast to multiple destination communication modules at one time, and compared with a mode of setting an independent physical line between every two communication modules, a mode of realizing multiple-time respective data transmission can greatly save throughput and resource occupation of data streams while reducing the complexity of the line, and improve the transmission efficiency of data; moreover, the P0 transmits the data to the P1-P7 by using a clockwise ring line, and the P7 transmits the data to the P0-P1 by using a counterclockwise ring line, so that a data flow loop cannot be formed in the data transmission between the communication modules, the phenomenon of line deadlock is avoided, and the data transmission efficiency is improved.
Further, in an embodiment, when the transmission tasks of the data transmission system are more than two, that is, there are three or more data transmission tasks corresponding to the source communication modules respectively, the occurrence of a data loop can be avoided by setting an isolation point. Wherein, this isolation point includes two preset adjacent communication modules: the communication device comprises a first isolation communication module and a second isolation communication module, wherein a line between the first isolation communication module and the second isolation communication module is set to be in a state of inhibiting data transmission, namely two line segments of the first isolation communication module → the second isolation communication module or the second isolation communication module → the first isolation communication module are not communicated. Through the arrangement of the isolation point, the blocking of a data loop can be realized, the occurrence of the data loop is avoided, and further the line deadlock phenomenon possibly occurring in the data transmission process is avoided.
Illustratively, as shown in fig. 2, if the first isolated communication module is communication module P0 and the first isolated communication module is communication module P7, the line segments of P0 → P7 do not pass in the counterclockwise circular line, and the line segments of P7 → P0 do not pass in the clockwise circular line. In the subsequent data transmission task, when the number of the source communication module is smaller than the number of the destination communication module, the source communication module can be used as a first source communication module, the destination communication module is used as a corresponding first destination communication module, and the data of the first source communication module is broadcast to the first destination communication module along the clockwise direction through a clockwise ring line. And when the number of the source communication module is greater than that of the destination communication module, the source communication module can be used as a second source communication module, the destination communication module can be used as a second destination communication module, and the data of the second source communication module is broadcasted to the second destination communication module through a counterclockwise ring line. By the method, the data flow of P0 → P7 or P7 → P0 can be avoided, thereby avoiding the formation of a data loop and the occurrence of deadlock.
For example, the data transmission system may be applied to a multi-chip interconnection application scenario, and the data transmission system is specifically a multi-chip interconnection system. With the development of artificial intelligence, the computational power requirements of many scenes are higher and higher, and the absolute algorithm of a single chip is difficult to meet the requirements, so that a solution for multi-chip interconnection is needed, and the biggest problem of multi-chip interconnection is data transmission and sharing. The general solution is to create a wireless mesh network (mesh network) with multiple chips interconnected, and ensure that each two dies (Die) have an independent physical path, which is costly, and complex to implement. Each crystal grain (Die) is used as a communication module, and the data transmission system can reduce the cost and complexity and efficiently realize the data transmission of the multi-chip interconnection system.
In the embodiment of the application, because the ring lines (the clockwise ring line and the anticlockwise ring line) for connecting each communication module in series can be arranged in the data transmission system comprising a plurality of communication modules, the data transmission among the plurality of communication modules can be efficiently realized through the ring lines without independently arranging independent physical lines for every two communication modules; and, because clockwise ring circuit and anticlockwise ring circuit exist, make first source communication module can broadcast the data of first source communication module to first purpose communication module along the clockwise through clockwise ring circuit, second source communication module can broadcast the data of second source communication module to second purpose communication module along the anticlockwise through anticlockwise ring circuit, when having more than one data transmission task that different source communication modules correspond promptly, can transmit data through the ring circuit of different anticlockwise, avoid causing the data transmission annular circuit, thereby avoid appearing the phenomenon of loop deadlock, improve data transmission efficiency.
Example two:
fig. 3 shows a schematic flowchart of a data transmission method provided in an embodiment of the present application, where the data transmission method is applied to a source communication module in a data transmission system according to a first embodiment, and is detailed as follows:
in S301, a target transmission direction is determined.
In this embodiment of the present application, the source communication module is any one of the communication modules in the data transmission system in the first embodiment, which needs to send data. After the source communication module determines its data transmission task, it may determine its corresponding target transmission direction, which is clockwise or counterclockwise.
In one embodiment, the target transmission direction is determined by pre-negotiation between the source communication module and other communication modules to avoid data loops, and information of the target transmission direction is stored in a preset storage unit. When the source communication module needs to start a data transmission task, the information of the target transmission direction is firstly acquired from a preset storage unit, and the corresponding target transmission direction is determined.
In another embodiment, each communication module in the data transmission system has its own number, and the current target transmission direction may be determined according to the number of the corresponding destination communication module in the current data transmission task and a preset rule, so as to avoid occurrence of a data loop.
In S302, if the destination transmission direction is clockwise, the data of the source communication module is broadcast to the destination communication module along the clockwise direction through a clockwise ring line in the data transmission system.
In this embodiment, after determining that the target transmission direction is the clockwise direction, the data of the source communication module may be transmitted to the destination communication module along the clockwise direction through the clockwise ring line described in the first embodiment, so as to broadcast the data to the destination communication module.
For example, if the source communication module is the communication module P0 shown in fig. 2, after determining that the target transmission direction is clockwise, the data of P0 may be sequentially transmitted along the clockwise ring line P0 → P1 → P2 → P3 → P4 → P5 → P6 → P7, so that P1 to P7 can all sequentially receive the data of P0, thereby implementing the data broadcast of P0 through the clockwise ring line, and implementing efficient transmission of data.
In S303, if the target transmission direction is counterclockwise, the data of the source communication module is broadcast to the destination communication module along the counterclockwise direction through a counterclockwise ring line in the data transmission system.
In this embodiment of the application, after determining that the target transmission direction is the counterclockwise direction, the data of the source communication module may be transmitted along the counterclockwise direction to the destination communication module through the counterclockwise loop circuit described in the first embodiment, so as to broadcast the data to the destination communication module.
For example, if the source communication module is the communication module P7 shown in fig. 2, after determining that the target transmission direction is the counterclockwise direction, the data of P7 is sequentially transmitted along the counterclockwise direction P7 → P6 → P5 → P4 → P3 → P2 → P1 → P0 through the clockwise ring line, so that P6 to P0 can all sequentially receive the data of P7, thereby implementing the data broadcast of P7 through the counterclockwise ring line, and implementing efficient transmission of data.
In the embodiment of the application, data of the source communication module can be broadcasted to each destination communication module at one time through the annular line, so that the data transmission efficiency can be improved; in addition, the source communication module can adopt a clockwise ring line or a counterclockwise ring line to perform data transmission according to different target transmission directions, so that efficient and deadlock-free data transmission can be realized according to actual needs in the ring line.
Optionally, the step S301 includes:
and inquiring a preset routing table according to the number of the target communication module, and determining a target transmission direction corresponding to the target communication module.
In this embodiment of the present application, each communication module in the data transmission system has a corresponding number and a routing table, and the routing table stores information of transmission directions in which data of the communication module reaches other communication modules, and may further include information of a middle communication module through which the communication module needs to pass to reach a destination communication module. The preset routing table is specifically a table which is made and stored by avoiding a data loop through a certain rule. Specifically, for the preset routing table corresponding to the source communication module, the number of each other communication module and the information of the transmission direction of the communication module relative to the source communication module are stored, where the transmission direction may include a clockwise direction and a counterclockwise direction, and may represent the clockwise direction by 1 and represent the counterclockwise direction by 0.
After the destination communication module corresponding to the data transmission task of the current source communication module is determined, the number of the destination communication module can be obtained. Then, according to the number of the destination communication module, the preset routing table is inquired, that is, the information of the transmission direction stored corresponding to the number of the destination communication module can be obtained, and according to the information of the reverse transmission direction, the current target transmission direction can be determined.
Exemplarily, the source communication module is P2, a clockwise direction is denoted by 1, a counterclockwise direction is denoted by 0, and the preset routing table is as follows:
| numbering | Information of transmission direction |
| P0 | 0 |
| P1 | 0 |
| P2 | / |
| |
1 |
| |
1 |
| |
1 |
| |
1 |
| |
1 |
When the destination communication module is determined to be P4, the information of the transmission direction can be obtained by querying the preset routing table as follows: 1, so that it can be determined that the target transmission direction is clockwise.
In the embodiment of the application, the target transmission direction in the current stage can be efficiently and accurately determined through the preset routing table, and the data transmission efficiency is improved.
Optionally, the step S301 includes:
if the number of the destination communication module is greater than the number of the source communication module, determining that the target transmission direction is clockwise;
and if the number of the destination communication module is smaller than that of the source communication module, determining that the target transmission direction is the anticlockwise direction.
The embodiment of the application can specifically determine the current target transmission direction through the size comparison relationship between the numbers of the target communication module and the source communication module.
Specifically, when the number of the destination communication module is greater than the number of the source communication module, for example, the number of the slave communication module is P0, and the number of the destination communication module is P3, it is determined that the current destination transmission direction is clockwise.
Specifically, when the number of the destination communication module is smaller than the number of the source communication module, for example, the number of the slave communication module is P1, and the number of the destination communication module is P0, it is determined that the current target transmission direction is counterclockwise.
By the method of the embodiment of the application, when the number of the source communication module is the communication module with the smallest number in the data transmission system (for example, P0 shown in fig. 2), no matter which of the other destination communication modules is, the condition that the number of the destination communication module is greater than the number of the source communication module is met, that is, the corresponding destination transmission direction is clockwise. When the source communication module is the communication module with the largest number in the transmission system (for example, P7 shown in fig. 2), no matter which of the other destination communication modules is, the condition that the number of the destination communication module is smaller than the number of the source communication module is satisfied, that is, the corresponding destination transmission direction is counterclockwise. Therefore, in the data transmission system, the counterclockwise loop circuit does not have a segment P0 → P7, and the clockwise loop circuit does not have a segment P7 → P0, so that the communication module with the minimum number and the communication module with the maximum number can be isolated from forming a data loop, thereby avoiding the phenomenon of deadlock of the circuit, and improving the data transmission efficiency.
Optionally, the step S301 includes:
acquiring a first preset number and a second preset number; the first preset number is the number of a first isolation communication module, the second preset number is the number of a second isolation communication module, the first isolation communication module and the second isolation communication module are two preset adjacent communication modules which cannot directly transmit data, and the first preset number is smaller than the second preset number;
if the numbers of the source communication module and the destination communication module are both less than or equal to the first preset number, or the numbers of the source communication module and the destination communication module are both greater than or equal to the second preset number, then:
when the number of the destination communication module is larger than that of the source communication module, determining that the target transmission direction is clockwise;
and when the number of the destination communication module is smaller than the number of the source communication module, determining that the target transmission direction is in a counterclockwise direction.
In the embodiment of the application, the current target transmission direction can be flexibly determined by flexibly setting the isolation point. Wherein the isolation point comprises two preset adjacent communication modules: the communication module comprises a first isolated communication module and a second isolated communication module, and the number of the first isolated communication module is smaller than that of the second isolated communication module. The line between the first isolated communication module and the second isolated communication module is set to a state of inhibiting data transmission, namely, the two line segments of the first isolated communication module → the second isolated communication module, or the second isolated communication module → the first isolated communication module are not communicated. Through the arrangement of the isolation point, the blocking of a data loop can be realized, the occurrence of the data loop is avoided, and further the line deadlock phenomenon possibly occurring in the data transmission process is avoided.
After receiving the data transmission task, acquiring the number of the first isolation communication module to obtain a first preset number; and acquiring the number of the second isolated communication module to obtain a second preset number.
