Example one
Fig. 1 is a schematic flowchart of a routing path determining method according to an embodiment of the present invention, where the method is applicable to determining reply information before a route is congested in a data transmission process, and the method may be executed by a routing path determining apparatus, where the apparatus may be implemented by software and/or hardware and is generally integrated on a control device, and the control device may be considered as a device capable of implementing dynamic routing planning. As shown in fig. 1, a method for determining a routing path according to an embodiment of the present invention includes the following steps:
s110, at least two application messages are obtained, the transmission time slots included in each application message are the same, and the application messages are used for applying for routing paths in the transmission time slots.
In this embodiment, the application information may be information included in an application that the sending core proposes to the destination core before data transmission is performed between any two cores. The sending core may be a core applying for sending data, and the destination core may be a core receiving data.
The at least two application information obtained in this step may come from different cores, and each application information may correspond to one sending core. In this step, it can be considered that at least two cores apply for data transmission in the same transmission time slot when obtaining the application information that at least two transmission time slots are the same. Each application message may include a transmission timeslot, and the transmission timeslots of the application messages may be the same, and for example, any two cores may apply for data transmission in the same transmission timeslot. After the control device obtains the at least two application information, routing path planning can be performed for the routing node corresponding to each application information.
When a plurality of cores transmit data on a chip or an inter-chip network, in a transmission time slot, before data transmission is performed between the cores, application information needs to be sent through a sending core to request for routing required for sending the data. The data amount transmitted by each sending core to the corresponding destination core may be consistent, for example, the transmitted data amount may be a unit data amount, so that the control device performs routing planning for each core.
The application information may include source address information and destination address information. The source address information may represent an address of a source routing node corresponding to the sending core, and the destination address information may represent an address of a destination routing node corresponding to the destination core.
The source routing node and the destination routing node may be routing nodes corresponding to a sending core and a destination core, respectively, where one core is connected to a routing node corresponding to the core, that is, the core and the routing node appear in pairs, for example, before data transmission, the sending core may apply for a route for transmitting data to the destination core to the control device, and the application information corresponding to the application may include information of an address where the routing node corresponding to the sending core, that is, the source routing node, is located and information of an address where the routing node corresponding to the destination core, that is, the destination routing node, is located.
In some optional embodiments, part of the acquired application information may be the same among the plurality of application information. For example, a plurality of application information is obtained, where 2 application information are all used by the core a to apply for data transmission to the core b in the target transmission timeslot.
The transmission time slot may be a time gap for transmitting data, for example, the time is divided into a plurality of time slots which do not overlap with each other, different sub-channels are established by different time slots, and the route may be divided into a plurality of time slots, and data transmission is performed in each time slot. The transmission time slot may also be considered as a sending time slot, the sending core applies for sending data in the transmission time slot to the control device, and the control device may determine replication information for the sending core based on the application information, so as to determine a routing path for the sending core.
The routing path may be a path formed by connecting routing nodes, and each application information may be used to apply for a routing path. The routing node may be a routing node to which each core should be connected. Illustratively, a plurality of cores may be included in the network on chip, each core corresponds to a routing node, the routing nodes are uniformly distributed, and the routing nodes are connected with each other to form a routing path. The routing path applied by the application information in this embodiment may be used for data transmission.
And S120, determining reply information corresponding to each application information according to each application information and path resource information, wherein the path resource information indicates the occupation state of a routing path in the network.
The path resource information may be information characterizing the occupation states of all routing paths in the network, that is, the path resource information may be used to indicate the occupation states of all routing paths in the network. Wherein the occupied status may indicate occupied and unoccupied. The path resource information may be used to determine idle routing paths in the network to facilitate determination of routing paths.
The reply information may be information characterizing the reply result, and for example, the reply information may be the reply result indicating approval, and the reply information may also be the reply result indicating rejection. The replication information can be determined according to each application information and the path resource information. When the reply information includes a reply result indicating approval, the reply information may further include path information corresponding to the selected feasible routing path.
In this embodiment, the feasible routing path may be a routing path selected from all routing paths from an address corresponding to the source address information of the application information to an address corresponding to the destination address information of the application information, for example, at least one idle routing path is determined from all routing paths from an address corresponding to the source address information of the application information to an address corresponding to the destination address information of the application information, and the occupied states of all sub-paths of the idle routing path are idle, so that any idle routing path may be determined as the feasible routing path.
In one possible implementation, the feasible routing path indicates idle for the occupied status of each sub-path in the plurality of routing paths, and the routing path with the minimum number of nodes is experienced. The feasible routing path can be selected according to the number of nodes from the address corresponding to the source address information of the application information to the address corresponding to the destination address information of the application information. Therefore, when data transmission is carried out in the transmission time slot, each sub-path of the routing path is idle, and the data transmission efficiency can be improved by minimizing the number of the experienced nodes. The present disclosure does not limit the manner in which feasible routing paths are selected.
For example, selecting a feasible routing path may be determining multiple routing paths to be selected according to the source address information and the destination address information, where the number of nodes experienced by each routing path may not be completely the same. At least one routing path with each idle sub-path can be determined according to the path resource information in the transmission time slot, and the routing path with the least number of nodes in the at least one routing path with each idle sub-path is determined as a feasible routing path.
The feasible routing path may also be selected by determining a routing path with the smallest number of nodes among the multiple routing paths to be selected as a reference routing path, and determining whether the reference routing path is selected as the feasible routing path according to the path resource information in the transmission timeslot and the reference routing path. For example, it may be determined whether each sub-path of the reference routing path is idle, and if each sub-path of the reference routing path is idle, the reference routing path may be selected as a feasible routing path. If the reference routing path comprises the non-idle sub-path, removing the reference routing path from the plurality of routing paths to be selected, obtaining the removed routing path to be selected again, selecting the routing path with the least number of nodes again, and determining the reselected routing path as the reference routing path.
And determining the occupation state of each routing path according to the occupation state of the routing path in the network indicated by the path resource information. The approval information may include path information indicating the approved approval result and the selected feasible routing path, wherein the path information may be information identifying the feasible routing path. When the feasible routing path is selected, if the selection times are greater than a set threshold value or each routing path to be selected includes a non-idle sub-routing path (it is determined that there is no feasible routing path), the reply information may include a reply result indicating rejection.
If the reply information includes the path information of the selected feasible routing path, updating the path resource information in the transmission time slot, for example, modifying the occupation state of the sub-path included in the feasible routing path included in the reply information into occupation. The set threshold may be a preset value, and the specific value is not limited herein.
And S130, transmitting each batch of complex information.
After the application information is determined, the reply information may be transmitted to the core that transmits the corresponding application information, and the reply information may be a reply result of the application information transmitted by the corresponding core.
The reply information may also include path information, and the path information may be path information corresponding to the selected feasible routing path. When the reply information includes the path information corresponding to the selected feasible routing path, the path information may be transmitted to the routing node corresponding to the core that sent the application information. The routing node can determine the routing path of the routing node according to the path information, so as to transmit data.
For example, the path information may be used to indicate a connection direction between each hop of routing nodes between the source routing node and the destination routing node, where a path formed by connecting the routing nodes is a feasible routing path indicated by the path information.
In a routing path determining method provided in an embodiment of the present invention, at least two application messages are obtained, where transmission time slots included in each application message are the same, and the application messages are used to apply for a routing path in the transmission time slots; determining reply information corresponding to each application information according to each application information and path resource information, wherein the path resource information indicates the occupation state of a routing path in the network; and transmitting each of the batch messages. By the method, the reply information can be determined before the route is congested, and the hysteresis of route optimization is effectively reduced.
Further, each application message includes source address information and destination address information; correspondingly, the determining the reply information corresponding to each application information according to each application information and the path resource information includes: aiming at each application message, selecting a feasible routing path according to the source address message, the destination address message and the path resource message in the transmission time slot of the application message; determining path information corresponding to the selected feasible routing path and a reply result indicating approval as reply information of the application information; updating the path resource information in the transmission time slot according to the reply information; wherein, the occupation states of the sub-paths included in the feasible routing path all indicate idle.
The feasible routing path may be an unoccupied routing path determined by the source address information and the destination address information, and the occupation states of all sub-paths included in the feasible routing path indicate idling. When selecting a feasible routing path corresponding to the application information, the feasible routing path may be selected based on the address corresponding to the source address information included in the application information, the destination address information included in the application information, and path resource information in the transmission timeslot.
The feasible routing path can be selected according to the path resource information in the transmission time slot, and the occupation states of all sub-paths included in the feasible routing path are indicated to be idle, that is, not occupied. The sub-path may be a path between any two adjacent routing nodes within the feasible routing path, which may include one or more sub-paths. The occupation state indication idle state can be characterized in that the corresponding sub path is not occupied, and whether the sub path is occupied or not can be known through path resource information. Selecting a feasible routing path may include the following operations: selecting a routing path with the least number of nodes from source address information to destination address information, if the sub-path in the routing path is occupied, selecting the routing path which experiences the least number of nodes plus 1 node, if the sub-path in the routing path is occupied, continuing to select the routing path which experiences the least number of nodes plus 2 nodes, and selecting a feasible routing path when increasing one node number. And repeating the information until the times of selecting the feasible routing paths are larger than the set threshold value, or each routing path to be selected comprises a non-idle sub-routing path (no feasible routing path is determined), and then repeating the information to comprise the result of repeating the information indicating the rejection. The selecting times may be times of selecting a feasible routing path.
After the feasible routing path is selected, the replication information may include path information corresponding to the feasible routing path and a replication result indicating approval. The reply information may include a reply result indicating a rejection after the feasible routing path is not selected.
When the reply information includes the selected feasible routing path, the path resource information may be updated based on the feasible routing path included in the reply information, that is, the occupation state of the routing path in the network on chip is corrected. When determining the reply information of the next application information, the path resource information can be determined according to the updated path resource information.
Further, when a feasible routing path is selected, if the selection times are greater than a set threshold value or no feasible routing path is determined, the reply result indicating rejection is determined as the reply information of the application information.
After the reply result indicating rejection is determined as the reply information of the application information, the core of the application information can continue to send the application information of other transmission time slots to the control device, and the control device continues to determine the reply information of other transmission time slots.
Further, when a feasible routing path is selected, the routing path with the minimum number of nodes and the idle state of each sub-path among the routing paths from the address corresponding to the source address information of the application information to the address corresponding to the destination address information of the application information is determined as the feasible routing path.
The address corresponding to the source address information of the application information may be an address location where a source routing node included in the application information is located, and the address corresponding to the destination address information of the application information may be an address location where a destination routing node included in the application information is located, where the number of nodes may be the number of routing nodes.
Further, the transmitting each of the plurality of pieces of complex information includes: transmitting the reply result included in the reply information to a core sending the corresponding application information; and when the reply information comprises path information corresponding to the selected feasible routing path, transmitting the path information to a routing node corresponding to a core sending the corresponding application information.
After determining the reply information, the reply result may be transmitted to the corresponding core, and the path information may be transmitted to the corresponding routing node, so as to instruct the routing node to perform data transmission based on the path information.
Further, the application information is sent in a transmission time slot before the transmission time slot, and the application information is used for pre-applying for a routing path in the transmission time slot.
Before the transmission time slot transmits data, application information can be sent to the control device for applying for data transmission in the transmission time slot. For example, the application information may be sent in any transmission time slot before the transmission time slot, and the application information may be used to apply for a routing path in the transmission time slot in advance, so that the reply information may be determined before the transmission time slot transmits data.
Example two
Fig. 2 is a flowchart illustrating a routing path determining method according to a second embodiment of the present invention. When many cores pass through on-chip and inter-chip network data transmission, local routing over-congestion often occurs, so that partial data transmission time is long, and due to the influence of a barrel effect, next calculation operation can be performed after all data transmission is finished, so that the routing needs to be optimized.
The traditional static route optimization technology can realize the accurate control of route resources through methods such as precompilation and the like, but cannot process the situation of dynamic data. The dynamic routing technology can plan a routing path in real time according to the routing congestion condition in the operation process, but may need a more complex decision and scheduling mechanism. Since most of the methods adopt a post-scheduling mechanism, that is, measures are taken only after the route is congested, the route optimization has hysteresis and cannot reach an optimal scheme.
In the conventional dynamic routing technology, a sender, namely a sending core, requests a nearest sending routing node to transmit data, a route usually informs the sender whether the sender can send the data through a pressure feedback method, namely, the current routing node is not busy, the sender agrees to send the request and can send the request, and if the current node is busy, namely, a feasible routing path is occupied, the sending application is rejected. The method is difficult to dynamically control the busy condition of the route, and is easy to cause some local network congestion.
Therefore, how to realize the dynamic routing technology at a lower cost when the many cores transmit data through the network on and between the chips, and ensuring the data transmission efficiency becomes a technical problem to be solved urgently at present.
In the method for determining a routing path according to this embodiment, a route is divided into transmission slots according to time, and when a current transmission slot (denoted as nth slot) transmits data in the previous T transmission slots, data, that is, a transmission application, is sent, and a destination address, that is, destination address information, is notified. At this time, the network on chip may predict how much data that all nodes need to transmit in the nth time slot when the previous T transmission time slots transmit data, that is, determine the data that can be transmitted in the nth time slot according to the result of the batch. The optimized transmission path, i.e. the feasible routing path, of each application message is calculated through a network optimization algorithm (such as a water injection theorem), if an undesolvable path or a route is excessively congested, a sender can be informed that the sending application is invalid at any stage before a transmission time slot n comes, i.e. when the feasible routing path is selected, if the selection times are greater than a set threshold value or no feasible path is determined, the reply result indicating rejection is determined as the reply message of the application message, and at the moment, the application messages of other transmission time slots can be continuously acquired.
As shown in fig. 2, a network on chip has a plurality of cores, each core corresponds to a routing node, each sending core applies for a dynamic routing planning apparatus, that is, a control device, the dynamic routing planning apparatus transmits replication information of an application corresponding to each sending core, and the corresponding sending core transmits path information corresponding to a feasible routing path in the replication information to a corresponding node.
Each routing path of the network on chip under each transmission time slot can be regarded as a resource pool, namely path resource information, the routing path is arranged to send a certain amount of data equivalent to water injection in the resource pool, when the data injected by the routing path is more than other paths, namely the routing path is occupied, therefore, the data can flow into other paths, namely idle routing paths, and the final optimization result is that the data transmission amount of each routing path is basically equivalent. The method can make the data bypass to other paths, thereby relieving local congestion and realizing global optimization.
Fig. 3 is a flowchart of another routing path determining method according to the second embodiment of the present invention, where as shown in fig. 3, a core may be a many core, application information corresponding to each sending core may form a routing application list, each transmission time slot may be respectively planned through a path planning algorithm according to the routing application list, that is, replication information corresponding to each application information is determined according to each application information and path resource information, and path information corresponding to a feasible routing path in the replication information is transmitted to a path resource pool after planning. On the other hand, the replication result, i.e., the replication information, may be sent to the core, and the routing configuration information, i.e., the path information corresponding to the feasible routing path, may be transmitted to the routing node corresponding to the core, so as to indicate the routing node to determine the feasible routing path.
Fig. 4 is a scene schematic diagram of a routing path determining method according to a second embodiment of the present invention, and as shown in fig. 4, there are four data applications, that is, four application information.
Applying for 1, sending a core (1,2) to apply for transmitting data to a target core (2, 2);
applying for 2, sending a core (0,2) to apply for transmitting data to a target core (3, 2);
applying for 3, sending a core (0,3) to apply for transmitting data to a target core (3, 2);
applying 4, the sending core (1,2) applies for transmitting data to the destination core (2, 2);
the data volume of each application for transmission is consistent, that is, the data volume of each sending core for transmission is consistent, that is, the data volume is a unit data volume.
The routing path of application 1 is first planned. The routing paths (1,2) - (2,2) are routing paths, i.e. sub-paths, composed of two adjacent routing nodes in the network on chip, and the routing paths occupy one unit data volume, as shown by the arrow of application 1 in fig. 4, the routing paths are not occupied, so that application 1 obtains approval, i.e. indicates approval of the approval.
And then planning the routing path of the application 2. Although the distance of the routing path (0,2) - (1,2) - (2,2) - (3,2) is shortest, since the sub-path (1,2) - (2,2) is occupied, the routing path shown by the arrow of application 2 in fig. 4, which is not occupied, is adopted, and application 2 is approved.
And then planning the routing path of the application 3. Although the routing path of the sub-path passing through (1,3) - (2,3) or the sub-path of (1,2) - (2,2) is shortest, the occupied sub-path can only select other feasible routing paths from the idle paths, so that the routing path where the arrow of application 3 is located can be selected as shown in fig. 4, and application 3 is approved.
Finally, the routing path of application 4 is planned. Since the sub-paths (1,2) - (2,2), (1,1) - (2,2), (1,3) - (2,3) are all occupied, if no feasible routing path is selected from the idle routing paths, the application 4 is rejected, that is, the rejected reply result is indicated.
In all routing paths from the source node, i.e., the source routing node, to the destination node, i.e., the destination routing node, the number of times of selection during the optimal path transfer, i.e., the path, is greater than the set threshold (in this embodiment, the set threshold is 1), and then the rejected reply result is indicated.
The optimal path transfer can be expressed as that the number of nodes experienced from the source node to the destination node after the transfer is reduced, namely that the feasible routing path is idle as the occupation state of each sub-path in the feasible routing path, and the experienced routing path with the least number of nodes, and the non-optimal path transfer refers to that the number of nodes experienced from the source node to the destination node after the transfer is increased, namely that the routing path with the number increased than the number of routing nodes experienced in the previous optimal path can be selected from the idle routing path as the current feasible routing path after the current optimal path is occupied.
According to the routing path determining method provided by the embodiment, the batch information is obtained in a period of time before the real data transmission, and the routing can be optimized before the routing is congested at a low cost.
EXAMPLE III
Fig. 5 is a schematic structural diagram of a routing path determining apparatus according to a third embodiment of the present invention, which is applicable to a case where replication information is determined before excessive congestion occurs in a route during data transmission, where the apparatus may be implemented by software and/or hardware, and is generally integrated on a control device.

Further, when a feasible routing path is selected, if the selection times are greater than a set threshold value or no feasible routing path is determined, the reply result indicating rejection is determined as the reply information of the application information.
