The routing target node may specifically be a network node in each network node in at least a two-dimensional grid-connected network-on-a-chip that is consistent with the target coded address.

可选地，该使能控制信号可以具体为比特信号，其可以具体用于控制该临时电路的锁定与否。具体地，当临时电路锁定，且数据发送端将该使能控制信号设置为第一信号时，数据发送端可以将传输数据沿该临时电路发送给数据接收端。该第一信号可以具体为高电平信号，例如用一个或多个数字“1”代表该高电平信号。该传输数据中可以具体包括使能控制信号，利用该使能控制信号标注传输数据的有效性。Optionally, the enable control signal may be specifically a bit signal, which may be specifically used to control whether the temporary circuit is locked or not. Specifically, when the temporary circuit is locked and the data sending end sets the enable control signal as the first signal, the data sending end can send the transmission data to the data receiving end along the temporary circuit. The first signal may specifically be a high-level signal, for example, one or more numbers "1" are used to represent the high-level signal. The transmission data may specifically include an enabling control signal, and the enabling control signal is used to mark the validity of the transmission data.

可选地，该数据发送端可以为路由源节点对应的本地模块，该数据接收端可以具体为路由目标节点对应的本地模块。即数据发送端在使能控制信号的控制下开始沿临时电路发送传输数据给数据接收端。Optionally, the data sending end may be a local module corresponding to the routing source node, and the data receiving end may specifically be a local module corresponding to the routing target node. That is, the data sending end starts to send transmission data to the data receiving end along the temporary circuit under the control of the enable control signal.

可选地，数据发送端停止向数据接收端发送传输数据，并由数据接收端对接收到的数据发送端发送的传输数据进行校验，确定该传输数据是否通过校验。Optionally, the data sending end stops sending transmission data to the data receiving end, and the data receiving end checks the received transmission data sent by the data sending end to determine whether the transmission data passes the verification.

可选地，当数据发送端结束传输数据的发送后，数据发送端将临时电路的使能控制信号设置为第二信号，以停止向数据接收端发送传输数据。整个数据传输过程中，数据接收端接收到的有效的传输数据即为第一信号到第二信号之间的数据。Optionally, after the data sending end finishes sending the transmission data, the data sending end sets the enable control signal of the temporary circuit as the second signal, so as to stop sending the transmission data to the data receiving end. During the entire data transmission process, the effective transmission data received by the data receiving end is the data between the first signal and the second signal.

进一步地，在一个实施例中，在所述传输数据通过超时校验和循环冗余CRC校验的情况下，根据接收到的所述数据接收端发送的第三信号，解锁所述临时电路，所述第三信号为解锁所述临时电路的信号；Further, in one embodiment, when the transmission data passes the timeout check and the cyclic redundancy CRC check, the temporary circuit is unlocked according to the received third signal sent by the data receiving end, The third signal is a signal for unlocking the temporary circuit;

其中，所述校验包括所述超时校验和所述CRC校验。Wherein, the check includes the timeout check and the CRC check.

可选地，在数据发送端停止向数据接收端发送传输数据的情况下，数据接收端对接收到的传输数据进行校验，并判断该传输数据是否通过该校验。若数据接收端确定该传输数据通过该校验，则发送第三信号给数据发送端。Optionally, when the data sending end stops sending transmission data to the data receiving end, the data receiving end checks the received transmission data and judges whether the transmission data passes the check. If the data receiving end determines that the transmission data passes the verification, then send a third signal to the data sending end.

数据发送端接收到的该数据接收端发送的第三信号后，解锁该临时电路，释放资源，该第三信号可以具体为解锁该临时电路的信号，该信号可以具体由一个或多个比特组成。After receiving the third signal sent by the data receiving end, the data sending end unlocks the temporary circuit and releases resources. The third signal may specifically be a signal for unlocking the temporary circuit, and the signal may specifically consist of one or more bits. .

若数据接收端确定该传输数据通过该校验(包括超时校验和CRC校验)，则解锁该临时电路，释放资源。If the data receiving end determines that the transmission data passes the check (including the timeout check and CRC check), the temporary circuit is unlocked and the resources are released.

如果数据接收端确定该传输数据未通过该超时校验或CRC校验，则由于数据接收端本身就是路由源节点，由数据接收端确认本次数据传输失败，并生成失败报告，解锁该临时电路。If the data receiving end determines that the transmitted data does not pass the timeout check or CRC check, since the data receiving end itself is the routing source node, the data receiving end will confirm that the data transmission has failed, and generate a failure report to unlock the temporary circuit .

本发明提供的数据传输方法，基于片上网络建立路由源节点到路由目标节点的路由路径，并将该路由路径搭建为临时电路，基于该临时电路执行数据传输，其低延迟性和确定的资源提供了多路数据并行实时传输的大带宽和低延迟需求，提高了数据传输效率，同时能够在传输数据传输完成后解锁该临时电路，释放资源，避免资源占用所导致的拥堵。The data transmission method provided by the present invention establishes a routing path from a routing source node to a routing target node based on an on-chip network, and builds the routing path as a temporary circuit, and performs data transmission based on the temporary circuit.

该预设编码规则可以具体为按照节点之间的方位特征进行编码，得到各个节点(包括路由源节点、路由目标节点和中间节点)的地址。例如，路由源节点、路由目标节点和中间节点的地址包括两段编码，第一段编码地址是按照节点之间的东西方位进行编码得到的，第二段编码地址是按照节点之间的南北方位进行编码得到的，并由此编码指导路由，且该两段编码遵循为西小东大和北小南大的规则。The preset encoding rule may specifically be encoding according to the orientation characteristics between nodes to obtain addresses of each node (including routing source node, routing target node, and intermediate node). For example, the addresses of routing source node, routing destination node and intermediate node include two codes, the first coded address is coded according to the east-west orientation between nodes, and the second coded address is coded according to the north-south orientation between nodes It is obtained by encoding, and the routing is guided by this encoding, and the two segments of encoding follow the rules of Xixiaodongda and Beixiaonanda.

根据源编码地址和目标编码地址便可以知道路由源节点与路由目标节点之间的方位信息，根据该方位信息便可以确定路由源节点和路由目标节点之间的目标路由方向。The orientation information between the routing source node and the routing destination node can be known according to the source coded address and the destination coded address, and the destination routing direction between the routing source node and the routing destination node can be determined according to the location information.

在路由时，根据目标编码地址(即路由目标节点的地址)和当前节点(接收到路由包的节点)的地址比较，若目标编码地址中的第一段编码地址大于当前节点的地址中的第一段编码地址，则当前节点与路由目标节点的目标路由方向为东，向当前节点的东方向路由，反之向当前节点的西方向路由；若目标编码地址中的第二段编码地址大于当前节点的地址的第二段编码地址，则当前节点与路由目标节点的目标路由方向为南，向当前节点的南方向路由，反之向当前节点的北方向路由。When routing, compare the address of the target coded address (that is, the address of the routing target node) with the address of the current node (the node that receives the routing packet), if the first segment of the coded address in the target coded address is greater than the first segment in the address of the current node A coded address, the target routing direction between the current node and the routing target node is east, routing to the east of the current node, otherwise routing to the west of the current node; if the second coded address in the target coded address is greater than the current node The second segment of the coded address of the address, the target routing direction between the current node and the routing target node is south, routing to the south of the current node, and vice versa to the north of the current node.

沿目标路由方向，将路由包由路由源节点传输到路由目标节点，并确定路由源节点到路由目标节点之间的路由路径。Along the target routing direction, the routing packet is transmitted from the routing source node to the routing target node, and the routing path between the routing source node and the routing target node is determined.

最后一步路由路径是根据最后一步路由方向确定的，最后一步路由方向是根据最后一个中间节点的中间节点标识中的编码地址、目标编码地址和预设编码规则确定的。The routing path of the last step is determined according to the routing direction of the last step, and the routing direction of the last step is determined according to the encoded address in the intermediate node identifier of the last intermediate node, the target encoded address and the preset encoding rule.

本发明中，从路由源节点对应的源编码地址沿目标路由方向将路由包传输给目标编码地址对应的路由目标节点，并找到该路由过程路由包经过的各个中间节点。In the present invention, the routing packet is transmitted from the source coding address corresponding to the routing source node along the target routing direction to the routing target node corresponding to the target coding address, and each intermediate node that the routing packet passes through in the routing process is found.

需要说明的是，路由包每经过一个节点，路由包添加路径参数，包括：当前节点地址、入口和出口；将这三个参数加入路由包内，随着路由推进，路由包逐渐加长。路由目标节点接收到路由包后，由路由目标节点的目标设备拆包，并将路由包的内容，含数据传输信息和路由信息，记录在路由目标节点的连接外套内。It should be noted that each time the routing packet passes through a node, the routing packet adds path parameters, including: the current node address, entry and exit; these three parameters are added to the routing packet, and the routing packet gradually lengthens as the routing advances. After the routing target node receives the routing packet, the target device of the routing target node unpacks the packet, and records the content of the routing packet, including data transmission information and routing information, in the connection jacket of the routing target node.

本发明中，将路由过程中，路由包从路由源节点到第一步经过的中间节点之间的路由路径(即第一步路由路径)、路由包连续经过的多个中间节点之间的路由路径(即第二步路由路径，含多步)和路由包从最后一个中间节点到路由目标节点之间的路由路径(即最后一步路由路径)进行拼接，即可得到路由源节点到路由目标节点的路由路径。In the present invention, in the routing process, the routing path (i.e. the first step routing path) between the routing packet from the routing source node to the intermediate node that the first step passes through, the routing between a plurality of intermediate nodes that the routing packet passes through continuously The path (that is, the second-step routing path, including multiple steps) and the routing path between the routing packet from the last intermediate node to the routing target node (ie, the last step routing path) are spliced to obtain the routing source node to the routing target node routing path.

在确定满足路由拒绝条件的情况下，拒绝将路由包从路由源节点传输到路由目标节点，路由拒绝条件包括路由目标节点的本地模块处于数据传输状态，或将路由包从路由源节点传输到路由目标节点经过的任意中间节点的所有出口均处于忙碌状态。When it is determined that the routing rejection condition is met, the routing packet is refused to be transmitted from the routing source node to the routing target node. The routing rejection condition includes that the local module of the routing target node is in the data transmission state, or the routing packet is transmitted from the routing source node to the routing node All exits of any intermediate nodes that the target node passes through are busy.

在路由过程中，若确定满足路由拒绝条件中的两种情况时，均可以拒绝将路由包从路由源节点传输到路由目标节点。第一种情况：路由目标节点的本地模块处于数据传输状态，其可以具体根据路由目标节点的目标设备是否正在传输数据确定；第二种情况：超级拥塞，即路由源节点与路由目标节点之间的任意可达中间节点均处于忙碌状态，例如，路由到任意一个中间节点时，该中间节点除入口外的其余几个出口均已被占用(有入无出)。During the routing process, if it is determined that the two conditions in the routing rejection condition are satisfied, the transmission of the routing packet from the routing source node to the routing target node may be refused. The first case: the local module of the routing target node is in the state of data transmission, which can be determined according to whether the target device of the routing target node is transmitting data; the second case: super congestion, that is, between the routing source node and the routing target node Any reachable intermediate node of , is in a busy state, for example, when routing to any intermediate node, the remaining several exits of the intermediate node except the entrance are already occupied (there is no entry but no exit).

根据路由源节点标识和路由目标节点标识，确定将路由包从路由源节点传输到路由目标节点的路由路径之后，方法，还可以具体包括：After the routing path for transmitting the routing packet from the routing source node to the routing target node is determined according to the routing source node identifier and the routing destination node identifier, the method may also specifically include:

判断路由目标节点是否在预设时间内接收到路由源节点传输的路由包；Judging whether the routing target node receives the routing packet transmitted by the routing source node within a preset time;

若确定路由目标节点在预设时间内未接收到路由包，则确定路由失败，并通过路由源节点删除路由路径。If it is determined that the routing target node has not received the routing packet within the preset time, it is determined that the routing has failed, and the routing path is deleted through the routing source node.

若确定数据传输在预设时间内未未完成，未解锁，则确定数据传输失败，并通过数据接收节点通知路由源节点删除路由路径。If it is determined that the data transmission has not been completed or unlocked within the preset time, it is determined that the data transmission has failed, and the data receiving node notifies the routing source node to delete the routing path.

该预设时间可以具体根据路由源节点设定的超时计数器进行设置。The preset time may be specifically set according to the timeout counter set by the routing source node.

路由源节点在发出路由包之前，综合考虑路由时间开销和数据传输时间开销，设定超时计数器，并开始倒计时。倒计时结束时，向路由源节点和路由经过的各个节点发起模块报告，若倒计时结束，路由目标节点还未收到该路由包，则此次路由发生超时错误，路由失败，并撤销锁定的路由路径，由路由源节点删除该路由路径。Before the routing source node sends out the routing packet, comprehensively consider the routing time overhead and the data transmission time overhead, set the timeout counter, and start counting down. When the countdown ends, a module report is initiated to the routing source node and each node that the routing passes through. If the countdown ends and the routing target node has not received the routing packet, a timeout error occurs in this routing, routing fails, and the locked routing path is revoked , the routing path is deleted by the routing source node.

需要说明的是，该临时电路还设有N个多播和广播功能。It should be noted that the temporary circuit also has N multicast and broadcast functions.

多播功能：传输数据传输的目标编码地址有多个(B个)，是否多播可以通过设置控制比特Bout是否为1实现。Multicast function: there are multiple (B) target coded addresses for transmission data transmission, and whether multicasting can be realized by setting whether the control bit Bout is 1.

多播路由：路由过程中，每完成一个目标编码地址路由，就由目标编码地址向源编码地址锁定一次。同时清除在该路由包的该目标编码地址，直至清除了所有N个目标编码地址。Multicast routing: During the routing process, each time a target coded address route is completed, the target coded address is locked to the source coded address once. At the same time, the target coded address of the routing packet is cleared until all N target coded addresses are cleared.

多播数传：路由源节点的连接外套收到了N次锁定之后开始数据传输。Multicast data transmission: The connection jacket of the routing source node starts data transmission after receiving N locks.

多播解锁：路由源节点完成了数据发送之后，向所有锁定节点发送解锁信号。Multicast unlocking: After the routing source node finishes sending data, it sends an unlocking signal to all locked nodes.

多播异常：路由源节点设置并执行超时倒计时，多播传输没有CRC校验，只有超时校验。Multicast exception: The routing source node sets and executes a timeout countdown, and there is no CRC check for multicast transmission, only a timeout check.

该临时电路的广播功能可以用于整个系统的重构。The broadcast function of this temporary circuit can be used for the reconfiguration of the whole system.

广播定义：由一个节点(路由源节点)向所有节点传送同样数据。Broadcast definition: A node (routing source node) transmits the same data to all nodes.

广播路由：目标编码地址为全为1时，清除全网络的其他连接，将源路由设为数据发端，全片上网络的其他节点设为数据接收端，并且均连到路由源节点。Broadcast routing: When the target coded address is all 1, clear other connections in the entire network, set the source router as the data sender, and set other nodes of the whole network on chip as data receivers, and all of them are connected to the routing source node.

广播数据：数据发送端在开始路由的某个时钟之后自动开始发送数据，无需等待、无需锁定。Broadcast data: The data sender automatically starts sending data after a certain clock that starts routing, without waiting or locking.

广播异常：路由源节点设置并执行超时倒计时，当出现超时错误时，解锁所有广播锁定的节点。广播传输没有CRC校验。Broadcast exception: The routing source node sets and executes a timeout countdown, and when a timeout error occurs, all broadcast-locked nodes are unlocked. Broadcast transmissions do not have a CRC check.

临时锁定电路的流水线定义：分为路由期间的路由流水线和数据传输期间的数传流水线。Pipeline definition of temporary locking circuit: divided into routing pipeline during routing and data transmission pipeline during data transmission.

路由流水线：连接外套用于执行路由的电路的流水线pipeline：路由包经过每个节点消耗一个流水线步；Routing pipeline: the pipeline pipeline that connects the circuit that is used to perform routing: the routing packet consumes a pipeline step through each node;

数传流水线：连接外套用于数据传输电路的流水线pipeline。每个节点的数据通道电路可为组合电路，亦可为插入流水线电路；数据传输时，锁定的链路以组合逻辑为主，终点节点设有流水线。路由在反向锁定前，根据路由节点数自动决定在某个节点加入一级流水线。Data transmission pipeline: the pipeline that connects the jacket to the data transmission circuit. The data channel circuit of each node can be a combined circuit, or can be inserted into a pipeline circuit; during data transmission, the locked link is mainly combined logic, and the terminal node is equipped with a pipeline. Before the routing is reverse locked, it is automatically determined to join the first-level pipeline at a certain node according to the number of routing nodes.

临时电路的撤销锁定：数据传输结束后，使能控制信号降为零，路由源节点的连接外套(可能是数据发送方，也可能是数据接收方)，在确认CRC检查正确后(可能是目标节点送来的CRC正确)，发出撤销电路锁定的命令，沿线的所有节点撤销锁定，释放电路资源。Unlocking of the temporary circuit: After the end of the data transmission, the enable control signal is reduced to zero, and the connection jacket of the routing source node (may be the data sender or the data receiver), after confirming that the CRC check is correct (may be the target The CRC sent by the node is correct), issue a command to cancel the circuit lock, all nodes along the line cancel the lock, and release the circuit resources.

图3是本发明提供的数据传输方法的流程示意图之三，图4是本发明提供的数据传输方法的流程示意图之四，如图3，图4所示，该方法包括：Fig. 3 is the third schematic flow diagram of the data transmission method provided by the present invention, and Fig. 4 is the fourth schematic flow diagram of the data transmission method provided by the present invention, as shown in Fig. 3 and Fig. 4, the method includes:

步骤1，路由源节点连接的本地模块产生一个数据传输需求，该数据传输需求包括：目标地址、发或收等传输控制和数据性质；Step 1, the local module connected to the routing source node generates a data transmission requirement, the data transmission requirement includes: destination address, transmission control and data properties such as sending or receiving;

步骤2，路由源节点的连接外套生成一个路由包，同时生成一个超时计数器，并开始递减计数，当完成数据传输被解锁的同时，确认CRC正确后(可能是路由目标节点送来的CRC正确)，清除该超时计数器，当超时计数器超时，路由源节点的连接外套解锁该传输的临时电路连接，并向路由源节点的本地模块报错，该路由包包括：源编码地址、目标编码地址、数据性质、传输查错需求等；Step 2, the connection jacket of the routing source node generates a routing packet, and at the same time generates a timeout counter, and starts to count down. When the data transmission is completed and unlocked, after confirming that the CRC is correct (maybe the CRC sent by the routing target node is correct) , clear the timeout counter, when the timeout counter times out, the connection coat of the routing source node unlocks the temporary circuit connection of the transmission, and reports an error to the local module of the routing source node, the routing packet includes: source coded address, destination coded address, data nature , transmission error checking requirements, etc.;

步骤3，路由源节点的连接外套按照目标编码地址的方向发送路由包，如果目标编码地址方向的出口已占用，则向任意空闲方向发包，同时将该节点和入出端口添入路由包，锁定入出口，同时向临近节点发送占用状态；Step 3: The connection jacket of the routing source node sends the routing packet in the direction of the target coded address. If the exit in the direction of the target coded address is already occupied, send the packet to any free direction, and add the node and the in-out port into the routing packet at the same time to lock the inbound port. exit, while sending occupancy status to adjacent nodes;

步骤4，路由过程中，对于每个收到包的节点：其连接外套按照目标编码地址的路由方向准备发送路由包，如果目标编码地址方向的出口已被占用，则向任意空闲方向准备发包，将该节点和路由入口出口添入路由包，发送路由包，锁定该连接外套的入出口；Step 4, during the routing process, for each node that receives the packet: its connection jacket prepares to send the routing packet according to the routing direction of the target coded address, if the exit in the direction of the target coded address is already occupied, prepares to send a packet in any free direction, Add the node and routing entry and exit into the routing package, send the routing package, and lock the entry and exit of the connection jacket;

步骤5，直到路由包到达路由目标节点，路由目标节点的连接外套拆包并向路由目标节点的本地模块投递该路由包的参数，路由目标节点的本地模块解析数据，如果路由目标节点的本地模块正在传输数据，则向路由源节点发送路由失败，如果路由目标节点的本地模块没有正在传输数据，可以接收或发送数据，则路由目标节点锁定路由目标节点；Step 5, until the routing packet reaches the routing target node, the connection jacket of the routing target node unpacks and delivers the parameters of the routing packet to the local module of the routing target node, and the local module of the routing target node parses the data. If the local module of the routing target node If the data is being transmitted, sending the route to the routing source node fails. If the local module of the routing target node is not transmitting data and can receive or send data, the routing target node locks the routing target node;

步骤6，如果路由目标节点作为数据发送端，按照数据性质开始发送传输数据，同时使用使能比特标注传输数据的有效性；如果路由源节点是数据发送端，路由源节点在收到锁定路由后按照数据性质开始发送传输数据，同时使用使能比特标注传输数据的有效性；Step 6, if the route target node is the data sender, start sending the transmission data according to the nature of the data, and at the same time use the enable bit to mark the validity of the transmission data; if the route source node is the data sender, the route source node receives the locked route Start sending transmission data according to the nature of the data, and use the enable bit to mark the validity of the transmission data at the same time;

步骤7，如果路由源节点是数据接收端，路由源节点的本地模块在使能控制信号例如使能比特控制下共同开始接收数据；如果路由目标节点是数据接收端，路由目标节点的本地模块在使能控制信号例如使能比特控制下共同开始接收数据；Step 7, if the routing source node is a data receiving end, the local module of the routing source node starts to receive data together under the control of an enabling control signal such as an enable bit; if the routing target node is a data receiving end, the local module of the routing target node is in Start receiving data under the control of an enable control signal such as an enable bit;

步骤8，当数据发送端结束传输数据发送，数据发送端将其连接外套的使能控制信号对应的使能比特拉低；Step 8, when the data sending end finishes transmitting data, the data sending end pulls down the enable bit corresponding to the enable control signal connected to the jacket;

步骤9，数据接收端接收到的传输数据(数据接收端可以是路由源节点或路由目标节点)，中包括使能比特为低的传输数据时，对该参数数据进行CRC校验，如通过CRC校验，发出CRC校验合格，如果数据接收端是路由目标节点，数据接收端发送解锁比特作为第三信号；路由源节点收到本节点或路由目标节点的第三信号，解锁临时电路；如未通过CRC校验(CRC失败)，则跳到步骤10；Step 9, when the transmission data received by the data receiving end (the data receiving end can be a routing source node or a routing target node), including the transmission data whose enable bit is low, perform a CRC check on the parameter data, such as by CRC Check, send out the CRC check pass, if the data receiving end is the routing target node, the data receiving end sends the unlock bit as the third signal; the routing source node receives the third signal from the node or the routing target node, and unlocks the temporary circuit; If the CRC check is not passed (CRC failure), skip to step 10;

步骤10，如果数据接收端是路由目标节点，路由目标节点确认失败，并向路由源节点发送CRC失败报告；如果数据接收端本身就是路由源节点，路由源节点确认失败，并向该节点的本地模块发送失败报告；然后路由源节点解锁该临时电路。Step 10, if the data receiving end is the routing target node, the routing target node fails to confirm, and sends a CRC failure report to the routing source node; if the data receiving end itself is the routing source node, the routing source node fails to confirm, and sends a local The module sends a failure report; the routing source node then unlocks the temporary circuit.

连接外套执行的两个主要功能具体为：The two main functions performed by the connection jacket are specifically:

第一个功能是通过路由建立电路连接：建立、锁定、撤销路由连接。这个功能是动态的，每次传输完成一次。(22)根据源路由本地模块发起器件的数据传输要求，编制路由包，完成：1，(22)节点保持记录临近节点的占用状况；2，根据路由的路由目标节点的地址和临近节点的占用状况，添加报头内容，记录路径，临时锁定该节点两个方向的入出路径，并向确定的方向发送路由包；3，依此路由方法路由，将最终找到路由目标节点的目标设备，并建立一条电路来连接路由源节点的本地模块与路由目标节点的本地模块；4，路由目标节点的本地模块确认传输请求，如空闲，则发出回传锁定电路的命令；如不空闲，则发出忙状态；5，锁定电路：建立一个定向的锁定的电路连接；6，保持锁定状态，支撑总线传输；7，撤销锁定：传输结束后，数据接收侧发出撤销电路锁定的请求，路由源节点执行电路撤销的命令，沿线的所有节点撤销锁定，释放电路资源；8，每个节点(作为路由源节点时)配有超时控制，异常超时的传输会被终止，并通过路由源节点的本地模块向系统上报。The first function is to establish circuit connections through routing: establish, lock, and revoke routing connections. This function is dynamic and is done once per transfer. (22) According to the data transmission requirements of the device initiated by the source routing local module, the routing package is compiled to complete: 1, (22) the node keeps recording the occupancy status of the adjacent nodes; 2, according to the address of the routing target node and the occupancy of the adjacent nodes status, add header content, record the path, temporarily lock the ingress and egress paths of the node in both directions, and send routing packets to the determined direction; 3. Routing according to this routing method will eventually find the target device of the routing target node and establish a circuit to connect the local module of the routing source node and the local module of the routing target node; 4. The local module of the routing target node confirms the transmission request, if it is idle, it will issue a command to return the locked circuit; if it is not idle, it will issue a busy state; 5. Lock circuit: establish a directional locked circuit connection; 6. Maintain the locked state and support bus transmission; 7. Unlock: After the transmission is completed, the data receiving side sends a request to cancel the circuit lock, and the routing source node executes the circuit cancellation. Command, all nodes along the line cancel the lock and release circuit resources; 8. Each node (as a routing source node) is equipped with a timeout control, and abnormal timeout transmissions will be terminated and reported to the system through the local module of the routing source node.

第二个功能是使用电路传输数据：电路锁定后，开始在电路上传输数据。路由源节点或路由目标节点均可发送数据，发送的数据被使能比特生效，发送结束后使能比特消失，数据接收方根据CRC校验结果做数据接收报告，路由源节点收到报告立即解锁电路，释放电路资源。The second function is to use the circuit to transmit data: after the circuit is locked, start transmitting data on the circuit. Both the routing source node and the routing target node can send data, the sent data is enabled by the enable bit, and the enable bit disappears after the transmission is completed, the data receiver makes a data reception report according to the CRC check result, and the routing source node unlocks immediately after receiving the report Circuit, to release circuit resources.
