Description

Data sending method, communication device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 27, 2024, with application number 202410119488.3 and application name “A data sending method, communication device and storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communication technology, and in particular to a data sending method, a communication device, and a storage medium. Background Art

[0003] Currently, optical modules are widely used for high-speed interconnection between data center devices. In the current artificial intelligence (AI) training parameter plane network, mainstream AI servers, neural network processing units (NPUs) or graphics processing units (GPUs) need to be interconnected through optical modules or copper cables.

[0004] Because copper cables support short distances and cannot be deployed across racks, they are currently primarily connected to servers via optical modules. Furthermore, due to limitations on NPU / GPU capabilities and cost-effectiveness, most NPUs / GPUs only have one 200-gigabit (G) or 400-gigabit network interface card (NIC) port. Therefore, if the optical module plugged into an NPU / GPU NIC port fails, the remote direct memory access (RDMA) connection between the NPU / GPU and other NPUs / GPUs will be disconnected, leading to a timeout and interruption of the entire training task. Manual replacement of the optical module is required to restore training to the previous checkpoint and restart the training.

[0005] Since the light-emitting device cannot sense when a channel failure occurs in the light-emitting device, but the light-receiving device can sense it, fault notification between devices is an urgent problem to be solved. Summary of the Invention

[0089] Please refer to FIG1 . The following briefly describes the system architecture based on which the data transmission method in the embodiment of the present application is based:

[0090] In this system architecture, a communication device 101 is connected to multiple communication devices 102, and the communication device 101 and the communication device 102 are interconnected through an optical module. Specifically, the communication device 101 includes multiple interfaces, and the optical module 104 can be inserted into any one of the multiple interfaces, thereby realizing the connection between the communication device 101 and the optical module 104. The communication device 102 includes an interface, and the optical module 103 can be inserted into the interface, thereby realizing the connection between the communication device 101 and the optical module 103. The optical module 103 and the optical module 104 are connected through an optical fiber, thereby realizing the interconnection between the communication device 101 and the communication device 102 through the optical module.

[0091] It should be understood that after the optical module is inserted into the interface of the communication device 101 , the optical module and the communication device 101 have a connection relationship, and is the optical module connected to the communication device 101 , hereinafter referred to as “the optical module of the communication device 101 ”.

[0092] It should be understood that the optical module itself may be a component of the communication device 101. In this case, the "optical module of the communication device 101" below means that the communication device 101 includes the component optical module.

[0093] It should be understood that the communication device 101 can be a network device such as a switch, a router, a virtual switch, a virtual router, a packet transport network (PTN) device, an optical transport network (OTN) device, etc. This application does not limit the device form of the communication device 101.

[0094] It should be understood that the communication device 102 can be an NPU, a GPU, a network card in a server, or the server itself carried by the NPU or GPU. This application does not limit the device form of the communication device 102.

[0095] It should be understood that the communication device 102 may also be a network device such as a switch, a router, a virtual switch, a virtual router, a packet transport network (PTN) device, an optical transport network (OTN) device, etc. For example, in a data center network, the communication device 101 may be a spine switch, and the communication device 102 may be a leaf switch.

[0096] In a possible implementation, the communication device 101 and the communication device 102 may be interconnected using other communication devices, which may implement photoelectric conversion and / or data transmission, and the specific details are not limited here.

[0097] Please refer to Figure 2, which shows a scenario in which optical modules 103 and 104 are interconnected. The optical module 103 includes a transmitter optical subassembly (TOSA), a receiver optical subassembly (ROSA), and an optical digital signal processing (oDSP) module. The main function of the TOSA is to convert electrical signals into optical signals, and it usually includes optical devices such as lasers. The main function of the ROSA is to convert optical signals transmitted from the opposite TOSA into electrical signals. It consists of a photodiode, an optical interface, a metal or plastic housing, and an electrical interface. Similar to the TOSA, the specific components of the ROSA depend on the specific functions and applications of the optical module. It may also contain other components such as amplifiers to restore input signals that have degraded due to long-distance transmission. The oDSP module can be used to modulate and demodulate laser signals, thereby increasing data transmission speed.

[0098] Based on the above architecture, the present application proposes a data transmission method, which is introduced below using the failure of the optical module of the communication device 101 as an example. When one or more channels in the optical module of the communication device 101 fail, the communication device 102 senses the abnormality, and the communication device 102 uses N channels of the M channels between the optical module to receive and / or send data, and indicates that an abnormality has occurred in a channel at the opposite end (for the communication device 102, the opposite end is the communication device 101, and for the communication device 101, the opposite end is the communication device 102).

[0099] It should be understood that the data transmission method proposed in the present application can also be that one or more channels in the optical module of the communication device 102 fail. After the communication device 101 senses the abnormality, the communication device 101 indicates that there is an abnormality in the channel of the other end. That is to say, the solution implemented by the communication device 101 can also be implemented by the communication device 102. At this time, the solution implemented by the communication device 102 is implemented by the communication device 101.

[0100] In the embodiment of the present application, there are two ways to indicate that a channel abnormality has occurred on the other end, which are described below:

[0101] It should be understood that the steps performed by the first communication device, the second communication device, the first optical module, and the second optical module in the method can also be performed by some of the components therein (such as a processor, a chip or a chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the functions.

[0102] The first communication device in the method may be the communication device 102 in FIG. 1 , in which case the first optical module is the optical module 103 ; the second communication device may be the communication device 101 in FIG. 1 , in which case the second optical module is the optical module 104 .

[0103] 1. Indicate by turning off the light corresponding to the abnormal channel;

[0104] Referring to FIG3 , a data sending method in an embodiment of the present application includes:

[0105] 301. A first communication device obtains that a first channel corresponding to a first optical module is abnormal. The first channel is a channel between the first optical module and a second optical module, and the first optical module is connected to the first communication device.

[0106] In this embodiment, the second communication device transmits data to the first communication device via the second optical module, and the first communication device receives data transmitted by the second communication device via the first optical module. Specifically, multiple channels are established between the first and second optical modules for transmitting and / or receiving data. For example, eight channels are established between the first and second optical modules (e.g., channels between the TOSA of communication device 101 and the ROSA of communication device 102 in FIG2 ), enabling data transmission at a rate of 400 Gbps. For a first channel, the first channel connects the first and second optical modules. The second optical module includes an interface for connecting to the first channel, and the first optical module includes an interface for connecting to the first channel. The second optical module can control the light emission corresponding to the first channel using a laser, thereby enabling data transmission, or in other words, controlling data transmission. The first optical module, as the other end of the first channel, can also receive optical signals transmitted through the first channel, thereby enabling data reception. Of course, a single channel can enable both data transmission and data reception. That is, the second optical module can transmit data to the first optical module via the first channel, and the first optical module can receive data transmitted by the second optical module via the first channel. The first optical module can also send data to the second optical module through the same first channel. In this case, the second optical module receives the data sent by the first optical module through the first channel. If only data transmission can be achieved for one channel, it does not affect the implementation of the embodiment of the present application. In a specific implementation, there will be another corresponding channel to achieve data reception. For example, the second optical module sends data to the first optical module through the first channel, and the first optical module receives the data sent by the second optical module through the first channel. The first optical module sends data to the second optical module through another channel corresponding to the first channel, and the second optical module receives the data sent by the first optical module through this channel.

[0107] There are multiple ways for the first communication device to obtain the abnormality of the first channel corresponding to the first optical module:

[0108] In a first implementation, when an abnormality occurs in the second optical module connected to the second communication device, such as a laser aging failure, causing the light power corresponding to the first channel to decrease or cease to emit light, the first optical module connected to the first communication device senses the abnormality in the corresponding first channel and shuts down the signal sent to the first communication device. Specifically, the signal corresponding to the first channel passing between the first communication device and the first optical module is shut down. If the first communication device does not receive the signal corresponding to the first channel between the first communication device and the first optical module, it determines that the first channel is abnormal. This step can be implemented by the oDSP module in Figure 2.

[0109] In a second implementation, when an anomaly occurs in the second optical module connected to the second communication device, such as a laser aging failure, causing the light power corresponding to the first channel to decrease, the signal received by the first optical module connected to the first communication device is transparently transmitted to the first communication device. Specifically, transparent transmission includes an optoelectronic conversion operation, specifically, transmission is performed through the channel corresponding to the first channel between the first communication device and the first optical module. After receiving the signal, the first communication device determines that the signal quality is poor and determines that the first channel is abnormal. This step can be implemented by the oDSP module in Figure 2.

[0110] In a specific implementation manner, after the first communication device obtains that a first channel corresponding to a first optical module is abnormal, the first communication device puts the port corresponding to the first optical module in the first communication device into a DOWN state.

[0111] 302. The first communication device uses N channels among M channels corresponding to the first optical module to send and / or receive data, where the M channels are channels between the first optical module and the first communication device, the N channels do not include a second channel, and the second channel is at least one channel among the M channels corresponding to the first channel, and N is less than M.

[0112] After obtaining the abnormality of the first channel corresponding to the first optical module, the first communication device determines that the first channel corresponding to the first optical module to which it is connected has an abnormality, and all channels between the first optical module and the second optical module, for example, 8 channels, cannot be used for data transmission, and thus uses part of the channels excluding the abnormal channel for data transmission.

[0113] In a specific implementation, the first communication device and the first optical module include M channels (for example, the channels between the TOSA of the communication device 101 and the ROSA of the communication device 102 in FIG2 ), and the first optical module and the second optical module include X channels (for example, the channels between the ODSP chip and the ASIC chip of the communication device 102 in FIG2 ). In one implementation, X=M. In another implementation, X may not be equal to M, and there is a corresponding relationship between the M channels between the first communication device and the first optical module and the X channels between the first optical module and the second optical module. For example, X=8 and M=16, in this case, the two channels between the first communication device and the first optical module correspond to one channel between the first optical module and the second optical module. This application does not limit the number of X and M.

[0114] In one specific implementation, the first communication device uses N channels out of the M channels corresponding to the first optical module to send and / or receive data. Alternatively, the first communication device does not use channels other than the N channels out of the M channels to send and / or receive data. Specifically, the first communication device blocks all channels except the N channels out of the M channels corresponding to the first optical module, leaving the N channels unblocked. The N channels do not include a second channel. The second channel is at least one channel out of the M channels corresponding to the first channel, where N is less than M. In other words, the first communication device sends data to the first optical module through the N channels, and the first optical module receives data through the N channels. In this case, the first communication device uses some of the channels to send data to the first optical module. The data is then sent to the second optical module through Y channels corresponding to the N channels. The Y channels are the channels between the first and second optical modules. The Y channels do not include the first channel, thereby enabling the first optical module to send data using some of the channels of the first module, excluding the abnormal channel.

[0115] In a specific implementation, an exception also occurs in a third channel, where the third channel is a channel between the first optical module and the second optical module, and the first communication device uses N channels out of the M channels corresponding to the first optical module to send and / or receive data according to the first exception information, including:

[0116] The first communication device sends and / or receives data using N channels among the M channels corresponding to the first optical module, where the N channels do not include a fourth channel, which is at least one channel among the M channels corresponding to the third channel.

[0117] In one specific implementation, the method further includes determining a speed reduction condition. The speed reduction condition includes determining whether a rate corresponding to a non-abnormal channel satisfies a first rate. The first rate is a predefined, standard-compliant port rate, such as 200 Gbps. Satisfaction indicates that the rate corresponding to the non-abnormal channel is greater than or equal to the first rate.

[0118] Specifically, after the first communication device detects an anomaly in the first channel corresponding to the first optical module, it determines whether the rates corresponding to the remaining non-anomalous channels meet the first rate. Non-anomalous channels are channels other than the first channel. These can be all channels other than the first channel, or a portion of the channels other than the first channel. For example, the rate of the first communication device port is 400 Gbps, which means the rate of the first optical module is 400 Gbps. In the case of X = 8, including channels 0 through 7, with channel 6 being the first channel, one channel corresponds to a rate of 50 Gbps. Non-anomalous channels can be all channels other than the first channel, that is, the remaining seven channels, with a corresponding rate of 350 Gbps, meeting the first rate requirement of 200 Gbps. For another example, non-anomalous channels can be a portion of the channels other than the first channel, or four channels other than the first channel, such as channels 0, 1, 2, and 3. In this case, the rates corresponding to these four channels are 200 Gbps, also meeting the first rate requirement of 200 Gbps.

[0119] Specifically, after the first communication device obtains that the first channel and the third channel corresponding to the first optical module are abnormal, it will determine whether the rates corresponding to the remaining non-abnormal channels meet the first rate. Among them, non-abnormal channels are channels other than the first channel and the third channel. Non-abnormal channels can be all channels other than the first channel and the third channel, or they can be some channels other than the first channel and the third channel. Specifically, the method for determining whether the rates corresponding to the remaining non-abnormal channels meet the first rate is the same as the method for determining after only the first channel is abnormal, and will not be repeated here. Optionally, the non-abnormal channels are multiple channels that are adjacent in position, or in other words, the non-abnormal channels are multiple channels with consecutive channel numbers. Optionally, the non-abnormal channels include the first channel or the last channel. The first or last here can represent the first or last position, or the minimum or maximum number. For example, in the case of 8 channels, the first channel can be channel 0, and the last channel can be channel 7.

[0120] It should be understood that in the above implementation, when determining that the rate corresponding to the non-abnormal channel meets the first rate, it can also be determined whether the rate corresponding to the non-abnormal channel in the channel between the first communication device and the first optical module meets the first rate. The specific implementation can refer to the above implementation, which will not be repeated here.

[0121] For example, since a 200Gbps port requires four channels for data transmission, a maximum of four channels of the first optical module can fail, and the remaining four channels can form a 200Gbps port. As shown in Figure 4, if the first channel is channel 6 and the third channel is channel 5, the first and third channels meet the speed reduction conditions, and the first communication device can instruct the first optical module to reduce the speed.

[0122] Exemplarily, when the first communication device is an NPU, the rate of the NPU port is 400Gbps, or in other words, the rate of the first optical module connected to the NPU is 400Gbps. After the NPU obtains an abnormality in the first channel corresponding to the first optical module, the NPU switches the port rate from 400Gbps to 200Gbps. There are 8 channels between the first optical module and the second optical module, including channels 0 to 7, and the first channel is channel 6. There are 8 channels between the NPU and the first optical module, for example, channels A to H, where channel 6 corresponds to channel G. The NPU shields channels E, F, G, and H from channels A to H, and uses channels A, B, C, and D to send data. The port rate is reduced from 400Gbps to 200Gbps. The first optical module also uses channels 0, 1, 2, and 3 corresponding to channels A, B, C, and D to send data, reducing the transmission rate of the optical module to 200Gbps.

[0123] 303. The first communication device sends control information to the first optical module, for instructing the first optical module to turn off the light emission corresponding to the first channel, or actively adjust the optical signal corresponding to the first channel to a first abnormal signal.

[0124] The first abnormal signal includes a signal indicating low luminous power.

[0125] For example, in the above example, the NPU sends control information to the first optical module to instruct the first optical module to turn off the light corresponding to channel 7.

[0126] In one possible implementation, the control information may further instruct the first optical module to turn off the light corresponding to a third channel among the M channels, where the third channel does not belong to any of the N channels. For example, the control information may instruct the first optical module to turn off the light corresponding to channels 6 and 7 in the above example, where channel 7 is the third channel and channel 6 is the first channel.

[0127] It should be understood that the control information can also instruct the first optical module to turn off the light corresponding to other channels among the M channels. As long as turning off the light of the channels does not affect data transmission, it is within the scope of protection of this application. For example, in the above example, turning off channels 4, 5, 6, and 7 is feasible. This step can be implemented by the oDSP module in Figure 2.

[0128] It should be noted that the control information can be included in a message sent by the first communication device to the first optical module, or it can be carried in a signal sent by the first communication device to the first optical module or in an instruction sent by the first communication device to the first optical module. The specific details are not limited here.

[0129] It should be understood that the ports corresponding to the first optical module and the second optical module in the embodiment of the present application are 200Gbps / 400Gbps. In some possible implementations, the ports of the optical modules can also support other rates, which are not specifically limited here.

[0130] 304. The second communication device obtains an abnormality in the first channel corresponding to the second optical module, where the first channel is a channel between the first optical module and the second optical module, and the second optical module is connected to the second communication device. The abnormality in the first channel corresponding to the second optical module obtained by the second communication device includes: the second communication device does not receive the optical signal sent by the first optical module through the first channel, the first optical module actively turns off the light emission corresponding to the first channel, or the second communication device receives the first abnormality signal sent by the first optical module through the first channel.

[0131] The first abnormal signal includes a signal indicating low luminous power.

[0132] 305. The second communication device uses N channels out of M channels corresponding to the second optical module to send and / or receive data, where the M channels are channels between the second optical module and the second communication device, the N channels do not include the second channel, and the second channel is at least one channel out of the M channels corresponding to the first channel, and N is less than M.

[0133] The specific implementation of step 305 can refer to step 302. At this time, the steps implemented by the first communication device in step 302 are implemented by the second communication device, and the steps implemented by the first optical module are implemented by the second optical module. The details are not repeated here.

[0134] Optionally, in step 306, the second communication device sends control information to the second optical module, instructing the second optical module to turn off the light corresponding to the first channel, or to actively adjust the optical signal corresponding to the first channel to the first abnormal signal. This step can be implemented by the oDSP module and TOSA module in Figure 2.

[0135] After the first communication device and the second communication device both use N channels that can operate normally to transmit data, or in other words, after the first communication device and the second communication device both use non-abnormal channels to transmit data, the two communication devices negotiate normally so that the ports of the communication devices return to the UP state and operate normally.

[0136] In the embodiment of the present application, since the first communication device and the second communication device can send data by using part of the channels in the optical module to achieve speed reduction, the failure of one or more channels causing the port to be DOWN and the link between the ports to be unavailable, which in turn avoids the interruption of the AI ​​training task, thereby improving the training performance and thus improving the performance of the AI ​​service.

[0137] In one possible implementation, after the first communication device or the second communication device obtains the abnormality of the corresponding optical module, it will feedback the abnormal information to the user. After the training task is completed or the relevant training content is saved, the first communication device or the second communication device can prompt the user to replace the optical module. For example, when the second optical module of the switch is removed, all channels of the first optical module of the NPU cannot receive optical signals, resulting in an abnormality. At this time, the NPU restores the shielded multiple channels. When the second optical module is reinstalled to the switch and then initialized, the corresponding lights of all channels in the second optical module are turned on, all channels of the first optical module can receive optical signals, and the two ends negotiate to restore the UP state.

[0138] Second, indicate by sending fault information to the controller;

[0139] Please refer to FIG5 . A data transmission method according to an embodiment of the present application is provided. In this method, for the connection relationship between the first communication device and the first optical module, the connection relationship between the second communication device and the second optical module, the description of the channel between the first optical module and the second optical module, the description of the channel between the first communication device and the first optical module, and the description of the channel between the second communication device and the second optical module, reference may be made to the relevant parts of the above embodiments. The method includes:

[0140] 501. A first communication device obtains an abnormality in a first channel corresponding to a first optical module, where the first channel is a channel between the first optical module and a second optical module, and the first optical module is connected to the first communication device. This step may be implemented by the oDSP module in FIG. 2 .

[0141] 502. The first communication device sends and / or receives data using N channels among M channels corresponding to the first optical module, where the M channels are channels between the first optical module and the first communication device, the N channels do not include a second channel, and the second channel is at least one channel among the M channels corresponding to the first channel, where N is less than M.

[0142] The specific implementation of steps 501 and 502 in this embodiment can refer to the implementation of steps 301 and 302 in the embodiment shown in Figure 3 above, and will not be described in detail here.

[0143] 503. The first communication device sends fault information to the controller, where the fault information is used to indicate that an abnormality occurs in the first channel.

[0144] The first communication device generates fault information and reports it to the controller. The fault information includes one or more of first port information, second port information, the number of channels of the first port, and fault information of the first channel. The first port information includes the port number and IP address of the local port, and the second port information includes the port number and IP address of the remote port. It should be understood that the fault information may also include other information indicating the port or the first channel, which is not specifically limited here.

[0145] In a possible implementation, the Link Layer Discovery Protocol (LLDP) is enabled between the first communication device and the second communication device. The LLDP protocol is used to enable devices in a network to discover each other and notify the devices of device and port information of other connected devices.

[0146] In a possible implementation, the first communication device and the second communication device are connected to the controller via a management plane or a service plane network. The fault information is sent via the service plane or the management plane network.

[0147] 504. The second communication device receives fault information from the controller, where the fault information indicates that an abnormality has occurred in a first channel, where the first channel is a channel between a first optical module and a second optical module, and the second optical module is connected to the second communication device.

[0148] The controller notifies the fault information to the second communication device through the management plane or service plane network, and the second communication device receives the fault information from the controller.

[0149] Specifically, after the second communication device receives the fault information from the controller, the second communication device determines that the first channel is abnormal.

[0150] 505. The second communication device uses N channels among the M channels corresponding to the second optical module to send and / or receive data according to the fault information, where the M channels are channels between the second optical module and the second communication device, the N channels do not include the second channel, and the second channel is at least one channel among the M channels corresponding to the first channel, and N is less than M.

[0151] The specific implementation of step 505 in this embodiment can refer to the implementation of step 305 in the embodiment shown in Figure 3 above, and will not be described in detail here.

[0171] The interface unit 701 is configured to receive and / or send data using N channels out of the M channels, where the N channels do not include the second channel, and N is smaller than M.

[0172] The embodiment of the present application includes a data transmission system, including a communication device that performs steps 301 to 303 in FIG. 3 , and a communication device that performs steps 304 to 306 in FIG. 3 ;

[0173] or,

[0174] The communication device executes steps 501 to 503 in FIG. 5 , and the communication device executes steps 504 to 505 in FIG. 5 .

[0175] For example, see Figure 8, which is a schematic diagram of the structure of an NPU provided in an embodiment of the present application. Specifically, it can be represented as a neural network processor NPU 800. NPU 800 is mounted on the host CPU (host CPU) as a coprocessor and is assigned tasks by the host CPU. The core of the NPU is arithmetic circuit 803, which is controlled by controller 804 to extract matrix data from memory and perform multiplication operations.

[0176] In some implementations, the arithmetic circuit 803 includes multiple processing engines (PEs). In some implementations, the arithmetic circuit 803 is a two-dimensional systolic array. The arithmetic circuit 803 can also be a one-dimensional systolic array or other electronic circuitry capable of performing mathematical operations such as multiplication and addition. In some implementations, the arithmetic circuit 803 is a general-purpose matrix processor.

[0177] For example, assume there are input matrix A, weight matrix B, and output matrix C. The computation circuit retrieves the corresponding data of matrix B from weight memory 802 and caches it on each PE in the computation circuit. The computation circuit then retrieves the data of matrix A from input memory 801 and performs a matrix operation on it with matrix B. The partial or final matrix result is stored in accumulator 808.

[0178] Unified memory 806 is used to store input and output data. Weight data is directly transferred to weight memory 802 through direct memory access controller (DMAC) 805. Input data is also transferred to unified memory 806 through DMAC.

[0179] The bus interface unit (BIU) 810 is used for interaction between the AXI bus, the DMAC, and the instruction fetch buffer (IFB) 809 .

[0180] The bus interface unit 810 (BIU) is used for the instruction fetch memory 809 to obtain instructions from the external memory, and is also used for the storage unit access controller 805 to obtain the original data of the input matrix A or the weight matrix B from the external memory.

[0181] DMAC is mainly used to transfer input data in the external memory DDR to the unified memory 806 or transfer weight data to the weight memory 802 or transfer input data to the input memory 801.

[0182] The vector calculation unit 807 includes multiple operation processing units. When necessary, it further processes the output of the operation circuit, such as vector multiplication, vector addition, exponential operation, logarithmic operation, size comparison, etc. It is mainly used for non-convolutional / fully connected layer network calculations in neural networks, such as batch normalization, pixel-level summation, and upsampling of feature planes.

[0183] In some implementations, the vector calculation unit 807 can store the processed output vector to the unified memory 806. For example, the vector calculation unit 807 can apply a linear function and / or a nonlinear function to the output of the operation circuit 803, such as linear interpolation of the feature plane extracted by the convolution layer, or, for example, accumulate a vector of values ​​to generate an activation value. In some implementations, the vector calculation unit 807 generates a normalized value, a pixel-level summed value, or both. In some implementations, the processed output vector can be used as an activation input to the operation circuit 803, for example, for use in a subsequent layer in a neural network.

[0184] An instruction fetch buffer 809 connected to the controller 804 is used to store instructions used by the controller 804;

[0185] Unified memory 806, input memory 801, weight memory 802 and instruction fetch memory 809 are all on-chip memories. External memories are private to the NPU hardware architecture.

[0186] The processor mentioned in any of the above places may be a general-purpose central processing unit, a microprocessor, an ASIC, or one or more integrated circuits for controlling the steps of the method of FIG. 3 or FIG. 5 .

Alternatively, the memory 903 exists independently and is connected to the processor 901 via a communication bus 902. Alternatively, the memory 903 and the processor 901 are integrated together.

[0195] In some embodiments, the memory 903 is used to store program code 906 for executing the solution of the present application, and the processor 901 executes the program code 906 stored in the memory 903. In other words, the communication device implements the above method embodiment through the processor 901 and the program code 906 in the memory 903.
