This technology is widely used in various server products because of its maturity and stability. However, within the technical framework of the BMC chip, there is a low-speed bus for communicating with the host's low-bandwidth devices - the LPC (Low Pin Count) bus. Since its introduction in 1998, this bus has been an important bridge connecting the BMC chip with external devices.

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figure 1 The baseboard management controller chip of the present invention is described.

[0032] Figure 1 It is a structural schematic diagram of the baseboard management controller chip provided by the present invention.

[0033] like Figure 1 As shown, the baseboard management controller chip includes a CAN controller module and a CAN transceiver module.

[0034] CAN (Controller Area Network) is a widely used fieldbus. The CAN protocol is a serial asynchronous data communication protocol. It is widely used in the automotive control and industrial control fields because of its high-speed communication and mature mechanisms for error and error frame processing.

[0035] In the specific implementation process, various types of CAN controller modules can be used. As an example, the CAN controller can be a CAN controller of the NXP TJA144x series, which supports the CAN FD protocol and is compatible with the traditional CAN2.0 communication. A single transmission can achieve more data than the ordinary CAN protocol, and the rate can reach up to 5Mbits / s, which is 5 times higher than the traditional CAN controller rate.

[0036] like Figure 1 As shown, the CAN controller module is mounted on the system bus in the baseboard management controller chip, and the CAN controller module is connected to the CAN transceiver module.

[0037] The communication between the CAN controller module and the CAN transceiver module is a highly coordinated process, involving multiple links such as signal generation, transmission, reception, conversion, and error handling. The two modules work closely together to achieve efficient and reliable data transmission on the CAN bus.

[0038] The CAN transceiver module is used to communicate with the CAN peripheral connected to the baseboard management controller chip to obtain the CAN data frames collected by the CAN peripheral.

[0039] The CAN controller module is used to obtain CAN data frames from the CAN transceiver module and transmit the CAN data frames to the shared FIFO module through the system bus, so that the core of the baseboard management controller chip reads and processes the CAN data frames from the shared FIFO module.

[0040] A shared FIFO (First In, First Out) is a mechanism for sharing data between multiple processes or threads, and is often used to implement inter-process communication (IPC) or inter-thread communication. A FIFO is a special type of queue where elements are removed in the order they were added. In a shared FIFO, multiple processes or threads can access the same FIFO queue for writing and reading data. Data written to the FIFO will be stored in the order in which it was written, and will maintain this order when it is subsequently read.

[0041] During the specific implementation process, since the amount of data obtained by the industrial control sensors is small, the baseboard management controller chip can be used to process the industrial control data obtained by the CAN transceiver module, or the CAN controller module can be used to process the industrial control data obtained by the CAN transceiver module, without being limited by the description of this specification.

[0042] In some embodiments, Figure 1 As shown, the baseboard management controller chip also includes an ESPI controller, a CPLD conversion module and a logic switch module.

[0043] like Figure 1 As shown, the logic switch module is mounted on the system bus, and the ESPI controller and the logic switch module are connected through the CPLD conversion module.

[0044] ESPI (Enhanced Serial Peripheral Interface) has higher bandwidth and communication rate than LPC bus, and is compatible with the communication specification of LPC bus. In addition, ESPI bus can convert all GPIO (General Purpose Input / Output) signals of Outof Band and sideband into in-band GPIO. This means that different types of signals that originally required multiple physical lines to transmit can now be transmitted in the form of data packets through ESPI bus. Because ESPI bus adopts a more efficient data transmission method, it reduces the number of physical pins connected between PCH (Platform Controller Hub) and baseboard management controller chip. This not only simplifies hardware design, but also reduces manufacturing costs. By reducing the required electrical devices and physical connections, ESPI bus helps save valuable resources such as PCB board space and power supply. This is especially important for server design, because servers usually need to handle large amounts of data and complex communication tasks.

[0045] The CPLD conversion module is used to realize the data format conversion between the ESPI protocol and the CAN protocol, and convert the CAN data frame from the logic switch module into data in the ESPI protocol format.

[0046] In the specific implementation process, CPLD (Complex Programmable Logic Device) can be used to design CAN receiving logic to receive data frames from the CAN bus; CAN data frames can be parsed to extract the data part that needs to be converted; according to the requirements of the ESPI protocol, the extracted data can be converted into the ESPI protocol format; and ESPI sending logic can be designed to send the converted data through the ESPI interface.

[0047] The logic switch module is used to obtain the CAN data frame from the system bus when the size of the CAN data frame transmitted into the shared FIFO module at a single time exceeds a preset threshold, and transmit the obtained CAN data frame to the ESPI controller through the CPLD conversion module.

[0048] In the specific implementation process, the logic switch module can be implemented through firmware and is not limited by the description of this specification.

[0049] As an example only, the logic switch module may periodically read the status register of the shared FIFO module to obtain the size of the CAN data frame transmitted into the shared FIFO module at a single time, and compare the read data with a preset threshold to determine the throughput of the CAN data frame transmission.

[0050] The ESPI controller is used to transmit the received CAN data frame to the server CPU connected to the baseboard management controller chip, so that the server CPU cooperates with the baseboard management controller chip to process the received CAN data frame.

[0051] In the specific implementation process, Figure 5 As shown in the figure, if the data throughput is too large, the logic switch module can be used to convert the CAN data frame into a protocol format through the CPLD conversion module, and then pass it to the server main CPU through the ESPI bus for shared processing. If the data throughput is small, the logic switch module does not transmit the CAN data frame, and the core of the baseboard management controller chip processes the CAN data frame by itself, thereby realizing flexible processing of the CAN data frame and effectively balancing the data load of the server CPU and the baseboard management controller chip.

[0052] The baseboard management controller chip provided by the present invention integrates an ESPI controller, a CPLD conversion module and a logic switch module while integrating a CAN controller module and a CAN transceiver module into the baseboard management controller chip. When the data throughput of the received CAN data frame is large, the CAN data frame can be sent to the server CPU through the ESPI controller after the protocol conversion is performed by the CPLD conversion module, thereby effectively reducing the burden of the baseboard management controller chip in processing high-throughput CAN data frames, overcoming the difficulty of low-rate communication caused by using an LPC bus, and improving data processing efficiency. In addition, since the security of the CAN bus is relatively high, the server downtime caused by data format errors can also be avoided.

[0053] Combine the following Figure 2-Figure 3 A method for processing a CAN data frame of the present invention is described.

[0054] Figure 2 This is one of the flow charts of the method for processing CAN data frames provided by the present invention.

[0055] In this embodiment, the data throughput of the CAN data frame acquired by the CAN transceiver module is less than a preset threshold, such as Figure 2 As shown, the method includes the following: Step 201: In response to a data receiving request from a CAN transceiver module, a CAN controller module receives a CAN data frame from the CAN transceiver module.

[0056] Step 202: The CAN controller module transmits the CAN data frame to the shared FIFO module via the system bus.

[0057] Step 203: The core of the baseboard management controller chip reads and processes the CAN data frame from the shared FIFO module.

[0058] In the embodiment provided by the present invention, in response to the data receiving request of the CAN transceiver module, the CAN controller module receives the CAN data frame from the CAN transceiver module; the CAN controller module transmits the CAN data frame to the shared FIFO module through the system bus; the core of the baseboard management controller chip reads and processes the CAN data frame from the shared FIFO module. Since the baseboard management controller chip is used to directly process the industrial control data, the communication capability of the baseboard management controller chip and the external device can be effectively improved, and the application scope of the baseboard management controller chip can be expanded.

[0059] Figure 3 It is a flow chart of a method for the core of a baseboard management controller chip provided by the present invention to process CAN data frames.

[0060] In this embodiment, the CAN data frame is industrial control sensor data, such as Figure 3 As shown, the method includes the following: Step 301: The core of the baseboard management controller chip reads a CAN data frame from a shared FIFO module.

[0061] Step 302: Process the CAN data frame and convert it into web page format data, so that the web page end interfaced with the baseboard management controller chip can obtain the web page format data and display it.

[0062] During the specific implementation process, the user can remotely log in to the web page interfaced with the baseboard management controller chip by entering the network address provided by the baseboard management controller chip on the maintenance terminal (for example, a host or a laptop computer), and then monitor the status of the industrial control sensors connected to the baseboard management controller chip through the web page, making it easier for maintenance personnel to monitor and manage the industrial control sensors.

[0063] Combine the following Figure 4-Figure 6 Another method for processing a CAN data frame according to the present invention is described.

[0064] Figure 4 This is the second flow chart of the method for processing CAN data frames provided by the present invention.

[0065] In this embodiment, the data throughput of the CAN data frame obtained by the CAN transceiver module is relatively large, such as Figure 4 As shown, the method includes the following: Step 401: In response to a data receiving request from a CAN transceiver module, a CAN controller module receives a CAN data frame from the CAN transceiver module.

[0066] Step 402: The CAN controller module transmits the CAN data frame to the shared FIFO module via the system bus.

[0067] Step 403, in response to the size of the CAN data frame transmitted into the shared FIFO module in a single time exceeding the preset threshold, the logic switch module obtains the CAN data frame from the system bus, and transmits the obtained CAN data frame to the ESPI controller through the CPLD conversion module.

[0068] Step 404: The ESPI controller transmits the received CAN data frame to the server CPU connected to the baseboard management controller chip, so that the server CPU cooperates with the baseboard management controller chip to process the received CAN data frame.

[0069] The baseboard management controller chip provided by the present invention can be applied to scenarios requiring large-scale data interaction, such as intelligent driving, industrial Internet, and hotel room smart furniture control, because it integrates an ESPI controller, a CPLD conversion module, and a logic switch module.

[0070] In application scenarios with large-scale data throughput, for example, when a CAN controller module is required to process large quantities of data in the industrial Internet, steps 401 to 404 can be used to enable the baseboard management controller chip and the server main CPU to share data, thereby effectively improving data processing efficiency.

[0071] Just as an example, Figure 6 and Figure 7 As shown, in the field of intelligent driving, the baseboard management controller chip provided by the present invention can be applied in large-volume data application scenarios such as monitoring the vehicle computer status of intelligent vehicles, laser radar, data generated by maps, and assisted driving calculations. By utilizing steps 401 to 404, the server CPU and the baseboard management controller chip can be collaboratively processed to obtain the vehicle computer status more quickly and reduce the time required to provide assisted driving calculations.

[0072] In the embodiment provided by the present invention, in response to a data receiving request of a CAN transceiver module, a CAN controller module receives a CAN data frame from the CAN transceiver module; the CAN controller module transmits the CAN data frame to a shared FIFO module through a system bus; in response to the size of a CAN data frame transmitted into the shared FIFO module at a single time exceeding a preset threshold, a logic switch module obtains the CAN data frame from the system bus, and transmits the obtained CAN data frame to an ESPI controller through a CPLD conversion module; the ESPI controller transmits the received CAN data frame to a server CPU connected to a baseboard management controller chip, so that the server CPU cooperates with the baseboard management controller chip to process the received CAN data frame. By using the ESPI controller, the CPLD conversion module and the logic switch module, when the data throughput of the CAN data frame received by the baseboard management controller chip is large, the CAN data frame can be sent to the server CPU through the ESPI controller after the protocol conversion is performed through the CPLD conversion module, thereby effectively reducing the burden of the baseboard management controller chip in processing large-throughput CAN data frames.
