Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically, to a communication information conversion method, system, device, and storage medium. Background Technology

[0002] With the development of chip packaging technology, Universal Chip Interconnect Express (UCIe), as a universal protocol for heterogeneous chip interconnection, has its sideband interface widely used for functions such as link management, parameter exchange, and register access. Internally, communication is generally achieved through the Advanced Peripheral Bus (APB) protocol. However, the chip's internal bus does not have a readily available sideband interface for connecting to the sideband of an external UCIe module. In existing technologies, direct interface between the chip's internal APB bus and the UCIe sideband interface presents the following problems: Multi-stage message processing is complex: UCIe Sideband messages need to be split into multiple message fragments and mapped to the APB side, or APB messages need to be classified and reassembled and mapped to the Sideband side, making the protocol conversion logic complex.

[0003] Low bandwidth utilization: Traditional protocol conversion methods typically use a single APB-Sideband channel for transmission and do not support multiple Sidebands simultaneously, i.e., a single APB interface to multiple Sideband interfaces.

[0004] Insufficient dynamic adaptation capability: Existing solutions lack the ability to identify and process message types, especially Management PortMessages with Data messages.

[0005] There is no error detection and retransmission mechanism: During the APB read phase, it is not possible to detect whether the currently read message frame has errors, and retransmission cannot be triggered if there are errors. Summary of the Invention

The memory 110, processor 120, and communication module 130 are electrically connected directly or indirectly to each other to achieve data transmission or interaction.

[0026] The memory 110 is used to store programs or data. The memory 110 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.

[0027] The processor 120 is used to read / write data or programs stored in the memory 110 and to perform corresponding functions.

[0028] The communication module 130 is used to establish a communication connection between the communication information conversion device 100 and other communication terminals through the network, and to send and receive data through the network.

[0029] It should be understood that, Figure 1 The structure shown is only a schematic diagram of the communication information conversion device 100. The communication information conversion device 100 may also include... Figure 1The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0030] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a communication information conversion method provided in an embodiment of the present invention. The method includes: S101. Obtain the communication information to be converted.

[0031] Please refer to Figure 3 , Figure 3 This is a schematic diagram illustrating the principle of a communication information conversion method provided in an embodiment of the present invention.

[0032] Heterogeneous chips refer to integrated circuits that integrate multiple different types of processor cores, such as CPUs, GPUs, and FPGAs, within a single chip. Different types of processor cores typically communicate using the APB interface protocol. However, different chips cannot communicate directly with each other via the APB interface. Existing chip-to-chip communication usually occurs through the Sideband interface protocol in the UCIe standard; however, communication between the Sideband interface protocol and the APB bus protocol presents various problems.

[0033] like Figure 3 As shown, when die0 and die1 interact, the APB bus information of die0 is first converted into Sideband information in the UCIe standard by the controller ucie ctrl inside die0. Then, the Sideband information is sent to the interface ucie phy of die0 through the interface ucie phy of die1. Finally, the controller ucie ctrl of die1 converts the Sideband information back into the APB bus information of die1. Here, APB can be a hardware unit or represent an information format that can be transmitted on the APB bus. Inside die0 or die1, one APB interface can correspond to multiple Sideband channels. There may be multiple information exchange channels between die0 and die1, such as 2X, 4X, 8X, 16X, etc. Each channel contains a mainband and a Sideband; the Sideband is the configuration channel, and the mainband is the main data channel.

[0034] S102. If the communication information to be converted is write information, then obtain the information frame structure of the write information, and map the write information to the chip's external interface according to the information frame structure. Before performing information conversion, it is necessary to determine the type of the acquired communication information, such as... Figure 3As shown, when chips interact with each other, there are two information conversion processes: the conversion of APB information from the first chip into UCIe information, and the conversion of UCIe information into APB bus information from the second chip. The external interface is the UCIe interface, which can convert APB bus information into multi-channel UCIe information, or simultaneously convert multiple APB bus information into their corresponding UCIe information.

[0035] The process of converting the APB bus information of the first chip into UCIe information is defined as the information writing process, and the process of converting the UCIe information into the APB bus information of the second chip is defined as the information reading process.

[0036] When the communication information to be converted is write information, the information frame structure of the APB bus information is obtained, and then the APB bus information is converted into UCIe information according to the information frame structure. S103. If the communication information to be converted is read information, the information frame type of the read information is obtained, and the read information is reconstructed and mapped to the bus according to the information frame type.

[0037] When the communication information to be converted into read information is obtained, the information frame structure of the UCIe information is acquired, and then the UCIe information is converted into APB bus information according to the information frame structure.

[0038] This embodiment improves protocol conversion efficiency and bandwidth utilization between the chip's external interface and the chip bus by using different information conversion methods according to the type of communication information to be converted, and solves the compatibility problem of communication protocols between the chip's external interface and the chip bus.

[0039] In one implementation, the splitting of written information and the reassembly of read information can be managed by a state machine. The state machine can abstract the behavior logic of the chip into a state transition model and automatically handle complex processes through preset rules, thereby improving the reliability and automation level of chip information conversion.

[0040] In one embodiment, the method further includes: If the communication information to be converted is the write information, then the write information is synchronized from the clock domain of the chip bus to the clock domain of the chip's external interface through a buffer. If the communication information to be converted is the read information, then the read information is synchronized from the clock domain of the chip's external interface to the clock domain of the chip bus through the buffer.

[0041] The buffer can be a First-In-First-Out (FIFO) data buffer. The buffer can coordinate the speed difference between the chip and the APB bus, thereby realizing information synchronization between the chip bus and the chip's external interface.

[0042] Please refer to Figure 4 Step S102 includes: steps S1021-S1023.

[0043] S1021. Obtain the header information frame of the written information and extract the opcode from the header information frame.

[0044] S1022. Determine the information frame structure and number of information frames for the written information according to the operation code.

[0045] S1023. Based on the information frame structure and the number of information frames, split and map the written information to the chip's external interface.

[0046] The header frame is the leading part of the write information frame, used to describe key data such as the data format, type, length, and control flags of the subsequent write information. Therefore, when retrieving write information, the control flags, including the opcode, can be extracted from the header frame.

[0047] In chip technology, the opcode is a core component of computer instructions, used to specify the specific type of operation the CPU performs, such as arithmetic operations, logical operations, or data transfer. The opcode determines the information frame structure and number of information frames to be written. APB information within heterogeneous chips is typically single-channel, while UCIe information is usually multi-channel. Therefore, the written information needs to be split and mapped according to the information frame structure and number of information frames before it can be read by the chip's external interface.

[0048] This embodiment obtains the header information frame of the write information, then determines the opcode of the write information based on the header information frame, and determines the information frame structure and number of information frames of the write information based on the opcode, thereby splitting and mapping the write information so that the split and mapped write information can be read by the chip's external interface, realizing the conversion of APB bus information to UCIe information.

[0049] In one implementation, the step of reconstructing and mapping the read information to the chip bus according to the information frame type includes: Obtain the header information frame of the read information, and determine the information frame type and number of information frames of the read information based on the high-order extension bits of the header information frame; The read information is reconstructed and mapped to the chip bus according to the information frame type and the number of information frames.

[0050] The high-order extension bits of the information frame are the one or more bits in the extended frame used to expand the 11-bit ID to a 29-bit ID. They usually refer to the IDE bit and the high-order part of the extended ID, and are used to support more nodes and more complex message identification.

[0051] Please refer to Figure 5 , Figure 5 This is a schematic diagram of a chip external interface information frame structure provided in this embodiment.

[0052] There are four types of UCIE Sideband interface information frames: the first type is Header only, the second type is Header with 32-bit data, the third type is Header with 64-bit data, and the fourth type is MPM with data (Management Port Message with Data).

[0053] The information being read is UCIE information, which is multi-channel information. Therefore, after determining the information frame type and number of information frames based on the high-order extension bits of the header information frame, the multi-channel UCIE information needs to be reconstructed and mapped into single-channel APB bus information so that it can be accurately recognized and transmitted by the APB bus.

[0054] This embodiment determines the information frame type and number of information frames by using the high-order extension bits of the header information frame, and then reassembles and maps the read information, thereby realizing the conversion of UCIE information from the chip's external interface to APB bus information inside the chip.

[0055] In one embodiment, the step of reconstructing and mapping the read information to the chip bus further includes: Determine the information reading order of the chip bus; The reassembly order of the read information is determined according to the read information order, and the read information is reassembled and mapped to the chip bus according to the reassembly order.

[0056] Since APB bus information is single-channel information, it cannot be read simultaneously when reading UCIE information from multiple channels. It can only be read in a certain order. Therefore, when reassembling the read information, it is also necessary to reassemble the read information according to the reading order of the APB bus to avoid data corruption that could lead to APB bus read failure.

[0057] In one embodiment, prior to the step of reconstructing and mapping the read information to the chip bus according to the information frame type, the method further includes: Obtain each information frame contained in the read information, and verify the key fields in each information frame; If the verification fails, a read information retransmission instruction is generated so that the device corresponding to the external interface of the chip retransmits the read information according to the read information retransmission instruction.

[0058] Before reassembling the read information, it needs to be verified. Verification can be performed by checking the key fields in each information frame. The key fields can be determined through data parity (DP) and control parity (CP).

[0059] If the verification passes, the read information can be reassembled; if the verification fails, a read information retransmission instruction is generated to retrieve the read information again.

[0060] To improve communication efficiency, a maximum number of retransmissions can be set. If the number of times the device corresponding to the external interface of the chip retransmits the read information exceeds the maximum number of retransmissions, a transmission error warning is generated and retransmission is stopped.

[0061] Similarly, the converted information can be verified before the written information is converted, and the written information can be retransmitted if the verification fails.

[0062] This embodiment verifies the read information before converting it, avoiding the conversion of erroneous information and improving the efficiency of information conversion. Moreover, it can retransmit the read data when there is an error, which improves the success rate of information exchange between chips.

[0063] In one embodiment, the present invention provides a communication information conversion system, including: a communication information conversion device, a chip bus, and a chip external interface, wherein the communication information conversion device is used to realize information conversion between the chip bus and the chip external interface; The communication information conversion device is used to acquire the communication information to be converted; If the communication information to be converted is write information, then the information frame structure of the write information is obtained, and the write information is split and mapped to the external interface of the chip according to the information frame structure; If the communication information to be converted is read information, then the information frame type of the read information is obtained, and the read information is reconstructed and mapped to the chip bus according to the information frame type.
