[0003] In a single chip design, multiple buses are used to connect various islands (a certain subsystem or core on the chip with specific properties) in the chip to form different ring or tree topologies to complete the transmission of instructions, reading, and transmission of island state. When multiple Chiplets are involved, the ring or tree topology of these buses needs to cross Chiplets, and the corresponding data flow also needs to be transmitted across Chiplets.

[0071] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0072] An embodiment of the present application provides a data transmission method based on UCIe, which is applied to a sending end of a data transmission system based on UCIe. The overall design schematic of the data transmission system based on UCIe is shown in Figure 1 The data transmission system based on UCIe can include a sending end (Low_speed_bus_mix_Tx) and a receiving end (Low_speed_bus_mix_Rx), and the sending end and the receiving end are in communication connection and are respectively used for transmitting and receiving data.

[0073] First, the specific scenario involved in the data transmission method based on UCIe provided by the embodiment of the present application is described. Figure 1 The overall design schematic of the data transmission system based on UCIe is shown in Figure 1 The scenario can involve cross-Chiplet data transmission through a UCIe module.

[0074] The data transmission method based on UCIe provided by the embodiment of the present application is described in detail in combination with multiple embodiments.

[0075] Please refer to Figure 2 An embodiment of the present application provides a data transmission method based on UCIe, which is applied to a sending end. The method can include the following steps S10-S20.

[0076] Step S10: Classifying a plurality of low-speed buses to be transmitted based on a preset processing mode to obtain classified low-speed buses.

[0077] The preset processing mode can be a mode of classifying different low-speed buses in different ways.

[0078] As an example, the plurality of low-speed buses to be transmitted are simply classified. The plurality of low-speed buses to be transmitted after the preset processing mode can be as follows.

[0079] The first type: low-speed buses with transmission interaction; the state of the low-speed buses with transmission interaction can include one of an idle state, a transmission state and a waiting state; for the effective state, the transmission data is normally transmitted; for the idle state or the waiting state, the transmission data stops transmission.

[0080] The second type: low-speed buses that are effective when changing; it should be noted that the transmission data of the low-speed buses that are effective when changing is detected, and data transmission is performed when the transmission data in the low-speed buses that are effective when changing changes.

[0081] The third type: low-speed bus valid at some time; the transmitted data is stored in a high-bit-width register in a bit displacement manner, and the register is transmitted as a whole after being filled for a fixed period.

[0082] In a specific implementation, the plurality of low-speed buses to be transmitted can be classified according to a preset processing manner, and then one or more classified low-speed buses of different types can be obtained.

[0083] Further, in another embodiment, the classified low-speed buses include one or more of the following types: low-speed bus with transmission interaction, low-speed bus valid at variable time, and low-speed bus valid at some time.

[0084] As an example, the classified low-speed buses can include a low-speed bus with transmission interaction.

[0085] As another example, the classified low-speed buses can include a low-speed bus with transmission interaction and a low-speed bus valid at variable time.

[0086] As yet another example, the classified low-speed buses can include a low-speed bus with transmission interaction, a low-speed bus valid at variable time, and a low-speed bus valid at some time.

[0087] In step S20, time slots corresponding to each classified low-speed bus are determined based on a preset time division multiplexing manner, and transmission data of each classified low-speed bus is sent to a receiving end according to the time slots.

[0088] The preset time division multiplexing manner can be a manner of dividing transmission time of each low-speed bus of the same sending end into a plurality of time slots in advance.

[0089] As an example, the transmission time slot of the low-speed bus with transmission interaction can be set as the 0th to 9th clock periods.

[0090] The transmission time slot of the low-speed bus valid at variable time can be set as the 10th to 19th clock periods.

[0091] The transmission time slot of the low-speed bus valid at some time can be set as the 20th to 29th clock periods.

[0092] After that, in the next round of transmission data, the transmission time slot of the low-speed bus with transmission interaction can be set as the 30th to 39th clock periods.

[0093] The transmission time slot of the low-speed bus valid at variable time can be set as the 40th to 49th clock periods.

[0094] The transmission time slot of the low-speed bus valid at some time can be set as the 50th to 59th clock periods.

[0095] The time interval can be a distance between transmission times of the two to-be-transmitted low-speed buses.

[0096] In a specific implementation, the time interval corresponding to each classified low-speed bus can be determined according to a preset time division multiplexing manner, and then the transmission data of each classified low-speed bus can be sent to the receiving end according to the time interval.

[0097] In this embodiment, the plurality of to-be-transmitted low-speed buses are classified by a preset processing manner to obtain classified low-speed buses, the time interval corresponding to each classified low-speed bus is determined based on a preset time division multiplexing manner, and the transmission data of each classified low-speed bus is sent to the receiving end according to the time interval. The plurality of low-speed buses are classified in different ways, which can reduce the number of transmission of invalid data and improve the transmission efficiency. The low-speed buses perform data transmission in the allocated time interval in a time division multiplexing manner, which can allocate UCIe user side bandwidth according to actual conditions, and flexibly adjust the time interval by configuration, which has strong expansibility.

[0098] Based on the foregoing embodiment, a second embodiment of the data transmission method based on UCIe is provided. In this embodiment, step S20 can include the following sub-steps A10-A30.

[0099] Sub-step A10, in the case where the classified low-speed bus is a low-speed bus with transmission interaction, detecting the current state of the low-speed bus with transmission interaction.

[0100] For the low-speed bus with transmission interaction, its state can be divided into an idle state, a transmission state and a waiting state.

[0101] When the low-speed bus with transmission interaction is in the idle state, no operation is performed.

[0102] When the low-speed bus with transmission interaction is in the transmission state, the master sends valid data, and at this time, the transmission data and the state are buffered in the internal FIFO (i.e., data buffer) by the first conversion module of the sending end.

[0103] When the low-speed bus with transmission interaction is in the waiting state, the first beat of the waiting state is buffered in the internal FIFO, and then sent to the receiving end for state recovery. The other beats of the waiting state are not transmitted, and at this time, the slave returns the response (i.e., response, reply), the master ends the waiting state and enters the idle state.

[0104] In a specific implementation, when it is detected that the classified low-speed bus is a low-speed bus with transmission interaction, the current state of the low-speed bus with transmission interaction can be further detected, so that the first conversion module can perform next step processing.

[0105] In sub-step A20, if it is detected that the current state is a transmission state, the transmission data of the low-speed bus with the existing state control and the transmission state are buffered by the first conversion module of the sending end, and the transmission data and the transmission state are sent to the first time division module of the sending end.

[0106] In the sending end, N conversion modules for different types of low-speed buses and one time division module can be included, and N≥1.

[0107] The bus types processed by the N low-speed bus conversion modules can include but are not limited to: low-speed buses with transmission interaction, low-speed buses with variable time validity, and low-speed buses with certain time validity.

[0108] As an example, the sending end can include a first conversion module, a second conversion module, and a third conversion module, and a first time division module.

[0109] The first conversion module is used to process the transmission data of the low-speed bus with transmission interaction. The first conversion module can be composed of decimation and FIFO.

[0110] The second conversion module is used to process the transmission data of the low-speed bus with variable time validity.

[0111] The third conversion module is used to process the transmission data of the low-speed bus with certain time validity.

[0112] The data path of the first time division module (tdm_mux_tx) can be N groups of input and one group of output, N≥1, and one group of period management signal input; each data input end is connected with the FIFO of each conversion module, and the tdm_mux module selects the corresponding data group according to the id output by the first time division module, and outputs the ready signal of the response path. When ready and have in the FIFO are a number (i.e., have is 1), the data is popped out from the FIFO and transmitted to the UCIe ip.

[0113] Please refer to Figure 3 , Figure 3 The working schematic diagram of the first time division module is shown in the figure. The tdm_bus_id can be the time slot slice id of each bus conversion module. The time slots occupied by each slice id are allocated according to the period management signal mng_reg. When allocating, the principle of allocating bandwidth> actual required bandwidth needs to be followed.

[0114] Please refer to Figure 4 ,Figure 4 Figure 1 is a schematic diagram of time slot allocation; Figure 4 As can be seen from Figure 1, the period management signal mng_reg is 32 bits wide, the data input group N = 4 of the low-speed bus, L = 8, at this time the period management signal mng_reg will [8; 0], [8; 8], [8; 16], [8; 24] bits respectively allocated to the periods T0 / T1 / T2 / T3.

[0115] In a specific implementation, when it is detected that the current state is in the transmission state, the transmission data of the low-speed bus with transmission interaction and the transmission state are buffered in the internal FIFO through the first conversion module; then the transmission data and the transmission state can be sent to the first time division module for subsequent processing by the first time division module.

[0116] Further, in an embodiment, if it is detected that the current state is the waiting state, the first beat of the waiting state is buffered through the first conversion module, and the first beat is transmitted to the first time division module; the first beat is sent to the receiving end within the time gap corresponding to the low-speed bus with transmission interaction through the first time division module, for use by the receiving end for state recovery (i.e., restoring the waiting state to the idle state).

[0117] In this embodiment, in the waiting state, the first beat of the waiting state is buffered in the internal FIFO of the first conversion module, and then sent to the receiving end for state recovery, and other beats of the waiting state are not transmitted; at this time, the waiting slave returns the response, and the master ends the waiting state and enters the idle state.

[0118] Further, in another embodiment, when it is detected that the current state is the idle state, the transmission data stops transmission, and no other operation is performed.

[0119] Please refer to Figure 5 , Figure 5 Figure 2 is a schematic diagram of the transmission state of the first conversion module; as can be seen from Figure 2, Figure 5 For the low-speed bus with transmission interaction, its state can be divided into the idle state, the transmission state and the waiting state; in the idle state or the waiting state, the data stops transmission; in the transmission state, the data is normally transmitted.

[0120] Sub-step A30, sending the transmission data and the transmission state to the receiving end within the time gap corresponding to the low-speed bus with transmission interaction through the first time division module.

[0121] In a specific implementation, within the time gap corresponding to the low-speed bus with transmission interaction, the transmission data and the transmission state can be sent to the receiving end through the first time division module.

[0122] As an example, the transmission time slots of low-speed buses with transmission interactions are set to 0 to 9 clock cycles; the transmission time slots of low-speed buses that are valid when changing are set to 10 to 19 clock cycles; and the transmission time slots of low-speed buses that are valid at certain times are set to 20 to 29 clock cycles.

[0123] That is, if the current state is in the transmission state during 0 to 9 clock cycles, the transmission data and transmission state can be sent to the receiving end through the first time division module;

[0124] If the current state is a waiting state during clock cycles 0 to 9, the first clock cycle of the waiting state can be sent to the receiving end through the first time division module.

[0125] In this embodiment, when the classified low-speed bus is a low-speed bus with transmission interaction, the current state of the low-speed bus with transmission interaction is detected. If the current state is detected to be a transmission state, the transmission data and the transmission state of the low-speed bus with transmission interaction are cached by the first conversion module of the transmitting end, and the transmission data and the transmission state are sent to the first time division module of the transmitting end. The first time division module sends the transmission data and the transmission state to the receiving end within the time gap corresponding to the low-speed bus with transmission interaction. Thus, the low-speed bus with transmission interaction can perform data transmission within the allocated time gap, which can reduce the number of invalid data transmissions and improve data transmission efficiency.

[0126] Based on the foregoing embodiments, a third embodiment of the UCIe-based data transmission method of the present invention is proposed. In this embodiment, step S20 may further include the following sub-steps B10 to B30:

[0127] Sub-step B10: If the classified low-speed bus is a low-speed bus that is valid when changing, perform change detection on the transmission data of the low-speed bus that is valid when changing.

[0128] Specifically, for low-speed buses that are valid during changes, data transmission occurs only when a change in the transmitted data within the low-speed bus that is valid during the change is detected; otherwise, data transmission does not occur.

[0129] In a specific implementation, when the classified low-speed bus is detected to be a low-speed bus that is valid when changing, the transmission data of the low-speed bus that is valid when changing can be detected for subsequent processing by the second conversion module.

[0130] In sub-step B20, when a change in the transmission data is detected, the transmission data is updated, the updated transmission data is cached by the second conversion module of the sending end, and the updated transmission data is sent to the first time division module of the sending end.

[0131] In a specific implementation, the transmission data in the low-speed bus valid at the time of change can be updated to obtain updated transmission data when the transmission data changes; and the second conversion module can then send the updated transmission data to the first time division module for subsequent processing by the first time division module.

[0132] As an example, refer to Figure 6 , Figure 6 The transmission diagram of the second conversion module; when the transmission data in the low-speed bus valid at the time of change changes from data1 to data2, the updated transmission data (data2) can be written into the internal FIFO of the second conversion module through push.

[0133] Step B30, sending the updated transmission data to the receiving end by the first time division module in the time gap corresponding to the low-speed bus valid at the time of change.

[0134] In a specific implementation, the updated transmission data can be sent to the receiving end by the first time division module in the time gap corresponding to the low-speed bus valid at the time of change.

[0135] As an example, the transmission time slot of the low-speed bus where transmission interaction exists is set to the 0th-9th clock period; the transmission time slot of the low-speed bus valid at the time of change is set to the 10th-19th clock period; and the transmission time slot of the low-speed bus valid at some time is set to the 20th-29th clock period.

[0136] That is, in the 10th-19th clock period, the updated transmission data can be sent to the receiving end by the first time division module.

[0137] In this embodiment, the transmission data of the low-speed bus valid at the time of change is detected when the classified low-speed bus is the low-speed bus valid at the time of change; when the transmission data is detected to change, the transmission data is updated, the second conversion module of the sending end buffers the updated transmission data, and sends the updated transmission data to the first time division module of the sending end; the first time division module sends the updated transmission data to the receiving end in the time gap corresponding to the low-speed bus valid at the time of change; thereby the low-speed bus valid at the time of change can perform data transmission in the allocated time gap, the transmission frequency of invalid data can be reduced, and the data transmission efficiency can be improved.

[0138] Based on the foregoing embodiments, the fourth embodiment of the UCIe-based data transmission method of the application is proposed. In this embodiment, step S20 can further include the following sub-steps C10-C30.

[0139] Sub-step C10: In the case where the classified low-speed bus is a low-speed bus valid at certain time, it is detected whether the transmission data of the low-speed bus valid at certain time is accompanied by a data valid bit.

[0140] The data valid bit (valid signal) can be an indicator of the validity of the transmission data of the low-speed bus valid at certain time. When valid is 1, the transmission data is valid.

[0141] In a specific implementation, when the classified low-speed bus is a low-speed bus valid at certain time, it can be further detected whether the transmission data of the low-speed bus valid at certain time is accompanied by a data valid bit for subsequent processing.

[0142] Sub-step C20: If it is detected that the transmission data is accompanied by a data valid bit, the transmission data and the data valid bit are processed by the third conversion module of the sending end through serial-parallel conversion, and the data after serial-parallel conversion is cached in the third conversion module and sent to the first time division module of the sending end.

[0143] The serial-parallel conversion processing mode can be a processing mode for converting n pieces of m-bit wide data into n*m-bit wide data according to a specific scenario.

[0144] As an example, refer to Figure 7 , Figure 7 a serial-parallel conversion diagram of the third conversion module;

[0145] Before serial-parallel conversion processing, serial low-bit width data data[1:0]: 2b01, 2b10, 2b10, 2b11;

[0146] After serial-parallel conversion processing, parallel high-bit width data data_p[7:0]: 8b01101011.

[0147] In a specific implementation, when it is detected that the transmission data is accompanied by a data valid bit, the transmission data and the data valid bit can be processed by the third conversion module through serial-parallel conversion to obtain data after serial-parallel conversion. Then, the data after serial-parallel conversion can be cached in the internal FIFO of the third conversion module, and the data after serial-parallel conversion can be sent to the first time division module.

[0148] Step C30: The data after serial-parallel conversion is sent to the receiving end by the first time division module in the time gap corresponding to the low-speed bus valid at certain time.

[0149] In a specific implementation, the data after the serial-to-parallel processing can be sent to the receiving end by the first time division module in the time gap corresponding to the low-speed bus valid at the certain time.

[0150] It should be noted that in the third conversion module, the data after the serial-to-parallel processing is stored in the high-bit-width register in a bit shift manner, and the entire register is transmitted after being full in a fixed period.

[0151] In the embodiment, in the case that the classified low-speed bus is a low-speed bus valid at a certain time, it is detected whether the transmission data of the low-speed bus valid at the certain time is accompanied by a data valid bit; if the transmission data is accompanied by the data valid bit, the third conversion module of the sending end performs serial-to-parallel processing on the transmission data and the data valid bit, caches the data after the serial-to-parallel processing, and sends the data after the serial-to-parallel processing to the first time division module of the sending end; the first time division module sends the data after the serial-to-parallel processing to the receiving end in the time gap corresponding to the low-speed bus valid at the certain time; thus, the low-speed bus valid at the certain time can perform data transmission in the allocated time gap, the transmission times of invalid data can be reduced, and the data transmission efficiency can be improved.

[0152] Further, an embodiment of the present application further provides a data transmission method based on UCIe, which is applied to a receiving end, and can include the following steps S30-S40.

[0153] In step S30, transmission data sent by a sending end is received; wherein the transmission data is classified by the sending end based on a preset processing mode on a plurality of low-speed buses to be transmitted, to obtain classified low-speed buses; time intervals corresponding to each classified low-speed bus are determined based on a preset time division multiplexing mode, and transmission data of each classified low-speed bus is sent according to the time intervals.

[0154] The transmission data is classified by the sending end based on a preset processing mode on a plurality of low-speed buses to be transmitted, to obtain classified low-speed buses; time intervals corresponding to each classified low-speed bus are determined based on a preset time division multiplexing mode, and transmission data of each classified low-speed bus is sent according to the time intervals. The steps are explained similarly to steps S10-S20 in the first embodiment described above, and details are referred to steps S10-S20 described above, which will not be described herein again.

[0155] In a specific implementation, the receiving end can receive the transmission data sent by the sending end.

[0156] Step S40, parsing and processing the transmission data.

[0157] In a specific implementation, after receiving the transmission data, the receiving end can parse and process the transmission data to parse the original data from the transmission data.

[0158] Further, in an embodiment, the step S40 can include the following sub-steps D10-D20:

[0159] Sub-step D10: when the second time division module of the receiving end receives the transmission data of the low-speed bus with transmission interaction, the second time division module sends the transmission data and state of the low-speed bus with transmission interaction to the first recovery module of the receiving end;

[0160] Sub-step D20: when it is detected that the low-speed bus with transmission interaction is in the transmission state, the first recovery module synchronously receives the transmission data according to the transmission state.

[0161] Among them, the receiving end can include 1 time division module and N recovery modules for different types of low-speed buses, N≥1;

[0162] The second time division module (tdm_mux_rx) can have a data path of a single group of input and N groups of output, N≥1, please refer to Figure 1 The input end is connected with the UCIe ip, if the recovery module ready corresponding to tdm_bus_id is high, the transmission data enters tdm_mux, and then flows to the corresponding recovery module.

[0163] The bus types handled by the N recovery modules for different types of low-speed buses can include but are not limited to: low-speed buses with transmission interaction, low-speed buses with changing valid time, and low-speed buses with valid time at certain moments.

[0164] As an example, the receiving end can include: a second time division module, a first recovery module, a second recovery module, and a third recovery module;

[0165] Among them, the first recovery module is used to process the transmission data of the low-speed bus with transmission interaction; according to the state transmitted and the response signal of the slave, the first recovery module is recovered. When the transmission state is received, the first recovery module synchronizes the transmission state; when the single beat waiting state is received, the first recovery module is set to the waiting state, and after receiving the response of the slave, it returns to the idle state. The state diagram of the first recovery module is shown in Figure 8 .

[0166] The second recovery module is configured to process transmission data of the low-speed bus valid at varying times. For the low-speed bus valid at varying times, the second recovery module directly reads the transmission data transmitted.

[0167] The third recovery module is configured to process transmission data of the low-speed bus valid at certain times. For the low-speed bus valid at certain times, the transmission data is accompanied by a data valid bit (i.e., a valid signal), and the third recovery module deserializes the transmission data and the valid signal.

[0168] The deserialization manner can be a manner of converting n*m-bit data into n-shot m-bit data.

[0169] As an example, refer to Figure 9 , and refer to Figure 9 for a deserialization diagram of the third recovery module.

[0170] Before deserialization, the parallel high-bit-width data data_p[7:0] is 8b01101011.

[0171] After deserialization, the serial low-bit-width data data[1:0] is 2b01, 2b10, 2b10, and 2b11.

[0172] In a specific implementation, for transmission data of the low-speed bus with transmission interaction, the second time division module sends the transmission data and the state of the low-speed bus with transmission interaction to the first recovery module. Then, when it is detected that the low-speed bus with transmission interaction is in a transmission state, the first recovery module can synchronize the transmission state to synchronize the reception of the transmission data according to the transmission state.

[0173] It should be noted that when it is detected that the low-speed bus with transmission interaction is in a waiting state, the first recovery module can be set to the waiting state according to the first shot of the waiting state transmitted. Then, the first recovery module can return to an idle state after receiving the response of the slave.

[0174] In addition, when it is detected that the low-speed bus with transmission interaction is in an idle state, the first recovery module has no other operation.

[0175] In the embodiment, when the second time division module of the receiving end receives the transmission data of the low-speed bus with transmission interaction, the second time division module sends the transmission data and state of the low-speed bus with transmission interaction to the first recovery module of the receiving end; when detecting that the low-speed bus with transmission interaction is in a transmission state, the first recovery module synchronously receives the transmission data according to the transmission state; thus, the low-speed bus with transmission interaction can perform data transmission in the allocated time interval, the number of invalid data transmission can be reduced, and the data transmission efficiency can be improved.

[0176] Further, in an embodiment, the step S40 can further include the following sub-step E10:

[0177] Sub-step E10: when the second time division module receives the transmission data of the low-speed bus valid at the time, the second time division module sends the transmission data to the second recovery module of the receiving end, and the second recovery module directly reads the transmission data.

[0178] In a specific implementation, for the transmission data of the low-speed bus valid at the time, the second time division module can send the transmission data to the second recovery module, and then the second recovery module can directly read the transmission data.

[0179] In the embodiment, when the second time division module receives the transmission data of the low-speed bus valid at the time, the second time division module sends the transmission data to the second recovery module of the receiving end, and the second recovery module directly reads the transmission data; thus, the low-speed bus valid at the time can perform data transmission in the allocated time interval.

[0180] Further, in an embodiment, the step S40 can further include the following sub-step F10:

[0181] Sub-step F10: when the second time division module receives the transmission data of the low-speed bus valid at some time, the second time division module sends the transmission data to the third recovery module of the receiving end, and the third recovery module performs deserializing processing on the transmission data.

[0182] In a specific implementation, for the transmission data of the low-speed bus valid at some time, the transmission data is accompanied by a data valid bit (valid signal), the second time division module can send the transmission data to the third recovery module; and then the third recovery module performs deserializing processing on the transmission data and the valid signal.

[0183] As an example, refer to Figure 9 , Figure 9The third recovery module is used for de-serializing the transmission data;

[0184] The n*m bit width data before de-serializing (n=4, m=2), and the parallel high bit width data data_p[7:0]: 8b01101011;

[0185] The n*m bit width data after de-serializing, and the serial low bit width data data[1:0]: 2b01, 2b10, 2b10, 2b11.

[0186] In the embodiment, when the second time division module receives transmission data of the low-speed bus valid at some time, the second time division module sends the transmission data to the third recovery module of the receiving end, and the third recovery module de-serializes the transmission data; thus, the low-speed bus valid at some time can perform data transmission in the allocated time interval.

[0187] In the embodiment, the transmission data is received, the transmission data is classified by the sending end based on a preset processing mode, and the classified low-speed bus is obtained; the time interval corresponding to each classified low-speed bus is determined based on a preset time division multiplexing mode, and the transmission data of each classified low-speed bus is parsed and processed according to the time interval; thus, the transmission frequency of invalid data can be reduced by classifying and processing multiple low-speed buses in different ways, and the transmission efficiency is improved; the data transmission of each low-speed bus in the allocated time interval by the time division multiplexing mode can allocate the UCIe user side bandwidth according to the actual situation, and the time interval can be flexibly adjusted by the configuration mode, and the expansibility is high.
