Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a control device and a server. Background Art

[0002] With the rapid growth of data centers, server management, monitoring, and security features are becoming increasingly important. Traditional server designs often integrate these features on the processor motherboard, resulting in complex hardware design and difficulty in maintenance. To address this, the Open Compute Project (OCP) has proposed a design specification for the Datacenter Secure Control Module (DC-SCM) to improve hardware maintainability and flexibility through modular design.

[0003] However, the DC-SCM technology used in related technologies has limitations in hardware design and functional integration. In particular, it tightly binds the management functions of the BMC (Baseboard Management Controller) to the Input / Output Interface (IO). This results in the need to replace the entire module in the event of a failure, increasing maintenance costs and reducing system reliability. Furthermore, this binding design lacks flexibility and cannot meet the needs of specific application scenarios, increasing hardware design complexity and limiting system scalability and adaptability.

[0032] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present application. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present application. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present application.

[0033] The terms used herein are only for describing specific embodiments and are not intended to limit this application. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0034] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0035] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0036] During the implementation of this application, it was discovered that in traditional server designs, the server's management, monitoring, and security functions are typically integrated onto the processor motherboard. Each generation of platform combinations requires a long period of design, testing, and verification. Furthermore, the updates and iterations of the CPU (Central Processing Unit) and the security management controller constrain each other, hindering the full performance of the platform. Although different platforms differ significantly, their security management features are generally similar. Therefore, using standardized modular design to accommodate the security management requirements of different platforms, reduce duplication of R&D resources, and accelerate product iteration has become an important development trend for data centers to adapt to changing needs and continuously upgrade.

[0037] To this end, the Open Compute Project has proposed the design specifications for the Data Center Security Control Module (DC-SCM). The DC-SCM shifts server management, security, and control functions from the processor motherboard to a standardized module. This modular design not only improves hardware maintainability and flexibility, but also reduces development costs, enabling universal management, security, and control functions across different platforms. Furthermore, the DC-SCM decouples the BMC development cycle from CPU iterations, accelerating the update and iteration of security management chips and CPUs while achieving cross-platform compatibility.

[0038] In related technologies, the Data Center Security Control Module (DC-SCM) is typically installed behind the server. This placement allows the DC-SCM to not only perform core server management, monitoring, and security control functions, but also integrates the input / output (IO) section, allowing it to function directly as an IO interface on the server's rear panel. Because the DC-SCM is installed behind the Host Processor Module (HPM), its placement allows for convenient connection to external devices, meeting the server's diverse management, data transmission, and device control needs.

[0039] However, DC-SCMs in related technologies have limitations. These limitations primarily arise in their hardware design and functional integration. First, traditional DC-SCMs tightly integrate the I / O interface with the management functions of the BMC (Baseboard Management Controller). While this design simplifies the hardware architecture to a certain extent, it also introduces numerous inconveniences. If a fault occurs in the BMC chip or I / O interface, the entire module must be replaced due to the integrated nature of the two. This increases maintenance costs and reduces system availability and reliability.

[0040] Furthermore, this binding design is inflexible in practical applications. Some application scenarios may only require BMC management functionality without additional I / O capabilities, or vice versa. However, traditional DC-SCM modules cannot directly meet these requirements, requiring the development of new BMC management boards or I / O interface cards. This undoubtedly increases hardware design complexity and cost, while also limiting system scalability and adaptability.

[0041] In summary, the DC-SCM in related technologies has significant deficiencies in hardware integration and functional flexibility, which to some extent limits its widespread application in complex environments such as data centers. To this end, embodiments of the present application provide a control device to improve flexibility and maintainability, reduce costs, and meet the needs of different application scenarios.

[0042] The control device of the present application includes: a separate baseboard management control module and an input / output interface module.

[0043] Figure 1 A schematic diagram of a baseboard management control module in a control device according to an embodiment of the present application is shown.

[0044] like Figure 1 As shown, the baseboard management control module 100 may include a storage unit 110 , a baseboard management controller 120 , and a security processor 130 .

[0045] According to an embodiment of the present application, the baseboard management control module is the core part of the control device, and the baseboard management control module can be used to implement the management, monitoring and security functions of the server.

[0046] In one embodiment, the baseboard management controller 120 may be a BMC, serving as the core processing portion of the baseboard management control module 100 , and configured to monitor the hardware status of the server, such as temperature, voltage, fan speed, and the like.

[0047] In one embodiment, the security processor 130 may be an integrated RoT (Root of Trust) security processor, which may be used to verify the security of system firmware and prevent malicious code injection.

[0048] In one embodiment, the storage unit 110 may be used to store BMC firmware, system logs, and configuration data.

[0049] According to an embodiment of the present application, the input-output interface module in the control device may include various IO interfaces for implementing communication and control with external devices.

[0050] Figure 2 A schematic diagram of an input and output interface module in a control device according to an embodiment of the present application is shown.

[0051] like Figure 2 As shown, the input / output interface module 200 may include a network interface 221 , a USB (Universal Serial Bus) interface 222 , a video interface 223 , a debugging interface 224 and a first communication interface 210 .

[0052] Specifically, the input / output interface module 200 may also include other types of IO interfaces. Figure 2 The interfaces shown in FIG are merely illustrative embodiments.

[0053] In one embodiment, the network interface 221 may include an RJ45 (Registered Jack 45) interface for network communication and support remote management and monitoring.

[0054] In one embodiment, the USB interface 222 can be used to connect an external storage device or other USB devices.

[0055] In one embodiment, the video interface 223 may include a VGA (Video Graphics Array) interface for video output.

[0056] In one embodiment, the debugging interface 224 may include a Micro USB (Micro Universal Serial Bus) interface for debugging the BMC or the entire system.

[0057] Figure 3 A schematic diagram of a control device according to an embodiment of the present application is shown.

[0058] like Figure 3 As shown, the control device includes a separate baseboard management control module 100 and an input / output interface module 200 .

[0059] Specifically, the baseboard management control module 100 and the input / output interface module 200 are respectively disposed on different baseboards.

[0060] According to an embodiment of the present application, the baseboard management control module 100 and the input-output interface module 200 in the control device can be electrically connected to jointly realize communication between the server and the external device; the baseboard management control module 100 and the input-output interface module 200 in the control device can also be used separately.

[0061] Based on the above Figure 1 The baseboard management control module 100 shown and the above Figure 2 As shown in the input / output interface module 200 , when the baseboard management control module 100 is electrically connected to the input / output interface module 200 , the baseboard management control module 100 can communicate with external devices via the input / output interface module 200 .

[0062] The first communication interface 210 can be used to communicate with the baseboard management control module 100 through a standardized connection interface.

[0063] In one embodiment, when the baseboard management control module 100 is disconnected from the input / output interface module 200 , the baseboard management control module 100 can still communicate with external devices via the input / output interface provided on the host processor module. Figure 4 A schematic diagram of a separate application baseboard management control module according to an embodiment of the present application is shown.

[0064] like Figure 4 As shown in FIG, the host processor module 410 is provided with an input and output interface 420, which may include various IO interfaces.

[0065] Therefore, if the host processor module 410 is provided with an input / output interface 420, and the server only requires the management functions of the baseboard management control module, the baseboard management control module can be used alone. The baseboard management control module 100 can communicate with external devices via the input / output interface 420 in the host processor module 410 to enable communication between the server and the external devices, and can also implement the management, monitoring, and security functions of the server.

[0066] In one embodiment, when the baseboard management control module 100 is disconnected from the input / output interface module 200, the input / output interface module 200 can also be electrically connected to the host processor module 410 through the first communication interface 210 in the input / output interface module, thereby realizing communication between the server and the external device.

[0067] Figure 5 A schematic diagram of a separate application input and output interface module according to an embodiment of the present application is shown.

[0068] like Figure 5As shown in , when the server only needs IO functions, the input and output interface module can be used alone. The input and output interface module 200 can be electrically connected to the host processor module 410 via the first communication interface 210 to achieve communication between the server and external devices.

[0069] According to the embodiments of the present application, Figure 5 The host processor module 410 shown in FIG. 4 is not provided with an input and output interface.

[0070] According to an embodiment of the present application, two separate independent modules are provided, namely a baseboard management control module and an input-output interface module. The baseboard management control module and the input-output interface module can be electrically connected to form a complete DC-SCM, or they can be used separately in scenarios where only the baseboard management control module or the input-output interface module is required. Moreover, when a partial failure occurs in the baseboard management control module or the input-output interface module, the failed module can be replaced separately without replacing the entire DC-SCM. Thus, the design of separate baseboard management control modules and input-output interface modules not only improves the flexibility and maintainability of the modules, but also reduces maintenance costs, while meeting the needs of different application scenarios.

[0071] According to another embodiment of the present application, the baseboard management control module 100 may further include a second communication interface.

[0072] Figure 5 A schematic diagram of a baseboard management control module in a control device according to another embodiment of the present application is shown.

[0073] like Figure 5 As shown, the baseboard management control module 100 may further include a second communication interface 610 . Thus, the baseboard management control module 100 can be electrically connected to the first communication interface 210 via the second communication interface 610 , thereby enabling communication between the baseboard management control module 100 and the input / output interface module 200 .

[0074] According to an embodiment of the present application, the electrical connection mode between the first communication interface and the second communication interface may include one of the following: direct plug connection and cable connection.

[0075] According to an embodiment of the present application, the electrical connection between the first communication interface and the second communication interface can be a direct plug-in connection or a cable connection based on the position distance between the baseboard management control module and the input / output interface module.

[0076] In one embodiment, when the baseboard management control module 100 and the input / output interface module 200 are located at the same location, the baseboard management control module 100 and the input / output interface module 200 can be directly connected via the first communication interface and the second communication interface.

[0077] Figure 7 A schematic diagram showing a first communication interface and a second communication interface connected by direct plug according to an embodiment of the present application is shown.

[0078] like Figure 7 As shown, the second communication interface 610 in the baseboard management control module 100 and the first communication interface 210 in the input / output interface module 200 can realize the electrical connection between the baseboard management control module 100 and the input / output interface module 200 by direct plug connection, so as to realize the communication between the baseboard management control module 100 and the input / output interface module 200.

[0079] According to the embodiments of the present application, Figure 7 As shown in the figure, the baseboard management control module and the input and output interface module after direct plug-in connection are consistent with the traditional DC-SCM form.

[0080] In one embodiment, when the baseboard management control module 100 and the input / output interface module 200 are not in the same location, the baseboard management control module 100 and the input / output interface module 200 are far apart, and the first communication interface and the second communication interface can be connected via a cable.

[0081] Figure 8 A schematic diagram showing a first communication interface and a second communication interface connected via a cable according to an embodiment of the present application is shown.

[0082] like Figure 8 As shown, the second communication interface 610 in the baseboard management control module 100 and the first communication interface 210 in the input / output interface module 200 can also realize the electrical connection between the baseboard management control module 100 and the input / output interface module 200 by cable connection, so as to realize the communication between the baseboard management control module 100 and the input / output interface module 200.

[0083] According to the embodiment of the present application, the first communication interface and the second communication interface are the communication bridges between the baseboard management control module and the input and output interface module. The communication interface adopts a standardized design and supports multiple communication protocols to ensure efficient communication between modules, realize rapid splicing and separation of modules, and ultimately realize collaborative work between modules.

[0084] According to an embodiment of the present application, when a second communication interface is provided in the baseboard management control module, the baseboard management control module and the input-output interface module can communicate via the first communication interface and the second communication interface by means of direct plug-in connection or cable connection, thereby ensuring efficient communication between modules, realizing rapid splicing and separation of modules, and ultimately realizing collaborative work between modules.

[0085] According to the embodiment of the present application, based on the above Figure 1 In the baseboard management control module shown, the baseboard management control module 100 is not provided with a communication interface. Therefore, in the case where the host processor module is provided with a third communication interface, the baseboard management control module can be integrated with the host processor module.

[0086] According to the embodiment of the present application, when a server uses a baseboard management control module alone, there are strict requirements on the size of the baseboard management control module. In this case, the baseboard management control module does not have enough space to place a communication interface. Therefore, a baseboard management control module without a communication interface is proposed. The baseboard management control module without a communication interface can be as follows: Figure 1 As shown in the baseboard management control module 100.

[0087] Therefore, there is not enough space in the baseboard management control module to place the communication interface. A third communication interface can be set on the host processor module, and the baseboard management control module can be installed on the host processor module, that is, the baseboard management control module is integrated with the host processing module.

[0088] Figure 9 A schematic diagram showing the integration of a baseboard management control module and a host processor module according to an embodiment of the present application is shown.

[0089] like Figure 9 As shown in FIG, the host processor module 410 is provided with a third communication interface 910. The baseboard management control module 100 is integrated with the host processor module 410 so that the integrated baseboard management control module has the function of a communication interface with the help of the host processor module 410.

[0090] In one embodiment, a connector may be provided between the baseboard management control module and the host processor module. The baseboard management control module is installed in the host processor module, that is, the baseboard management control module can be plugged into the host processor module via the connector, thereby achieving integration of the baseboard management controller and the host processor module.

[0091] According to an embodiment of the present application, when there is not enough space in the baseboard management control module to place a communication interface, a third communication interface can be set on the host processor module, and the baseboard management control module can be integrated with the host processor module to have the function of a communication interface, so as to realize communication between the baseboard management control module and the input and output interface module through the third communication interface.

[0092] According to an embodiment of the present application, the input-output interface module is also used to electrically connect to the third communication interface through the first communication interface, wherein the electrical connection method between the first communication interface and the third communication interface includes a cable connection; the baseboard management control module is also used to transmit the interface signal to the input-output interface module through the third communication interface.

[0093] In one embodiment, the first communication interface and the third communication interface may be electrically connected via a cable.

[0094] Figure 10 A schematic diagram showing the electrical connection between the integrated host processor module, baseboard management control module and input / output interface module according to an embodiment of the present application is shown.

[0095] like Figure 10 As shown, the input / output interface module 200 can be electrically connected to the third communication interface 910 through the first communication interface 210 to achieve communication between the baseboard management control module 100 and the input / output interface module 200 .

[0096] Specifically, the baseboard management control module 100 can transmit the interface signal to the third communication interface 910 in the host processor module 410 through the baseboard management controller 120. The third communication interface 910 can then transmit the interface signal to the first communication interface 210 in the input / output interface module 200 via a cable. In this way, communication between the baseboard management control module 100 and the input / output interface module 200 is achieved.

[0097] According to an embodiment of the present application, the first communication interface in the input / output interface module can be electrically connected to the third communication interface on the host processor module to realize communication between the input / output interface module and the baseboard management control module. During this process, the interface signal is transferred on the host processor module and then transmitted to the first communication interface.

[0098] According to an embodiment of the present application, the baseboard management control module is further configured to be connected to the input / output interface module via a connecting member.

[0099] According to the embodiments of the present application, Figure 10 The integrated host processor module and baseboard management control module are electrically connected to the input / output interface module. On this basis, the baseboard management control module 100 and the input / output interface module 200 can also be spliced ​​into a whole.

[0100] Figure 11 A schematic diagram showing the connection between the baseboard management control module and the input / output interface module according to an embodiment of the present application is shown.

[0101] like Figure 11 As shown, the baseboard management control module 100 and the input / output interface module 200 can be spliced ​​together through the connecting component 1110, so that their shape is similar to a DC-SCM.

[0102] According to the embodiments of the present application, Figure 10 and Figure 11In the embodiment shown in , the interface signal is still transferred through the third communication interface 910 on the host processor module 410 to realize the transmission of the interface signal between the baseboard management control module 100 and the input / output interface module 200 through the cable.

[0103] According to an embodiment of the present application, the input / output interface module and the baseboard management control module can also be spliced ​​by connecting components, so that their shape can be similar to that of a DC-SCM module, and the baseboard management control module and the input / output interface module can be ensured to remain fixed.

[0104] Based on the above content, in application scenarios where the server requires complete management functions, the input and output interface module and the baseboard management control module can be electrically connected through the communication interface. On this basis, the input and output interface module and the baseboard management control module can also be spliced ​​together through connecting components to form a complete DC-SCM.

[0105] The baseboard management and control module is responsible for monitoring the server's hardware status, while the input and output interface module is responsible for communicating with and controlling external devices. This configuration enables comprehensive server management, monitoring, and security features, making it suitable for most data center servers.

[0106] According to an embodiment of the present application, the baseboard management control module is integrated with the host processor module, the host processor is provided with a fourth communication interface, and the input and output interface module is also used to electrically connect to the fourth communication interface through the first communication interface to realize communication with external devices.

[0107] According to the embodiments of the present application, in some application scenarios, the server may only need BMC functions or IO functions. Therefore, according to the actual needs of the server, the baseboard management control module or the input and output interface module can be used separately.

[0108] For example, when the input and output interfaces of the server are already integrated on the motherboard of the host processor module, the baseboard management control module can be used alone to realize the management, monitoring and security functions of the server and to realize the communication and control between the server and external devices. Figure 4 shown.

[0109] In one embodiment, when the baseboard management control module is located in the host processor module, the management function can be completed by the host processor module. On this basis, the input and output interface module can be used alone to realize communication and control between the server and external devices.

[0110] Figure 12 A schematic diagram of a separate application input and output interface module according to another embodiment of the present application is shown.

[0111] like Figure 12 As shown, the host processor module 410 is provided with not only the baseboard management control module 100 but also the fourth communication interface 1210. The integration of the baseboard management control module 100 and the host processor module 410 means that the baseboard management control module 100 is arranged on the host processor module 410, and the fourth communication interface 1210 is also arranged on the host processor module 410.

[0112] Specifically, if the host processor module already has the management functions of the baseboard management control module, the server only needs IO functions, so the input / output interface module can be used alone. The input / output interface module 200 can realize communication and control between the server and external devices through the electrical connection between the first communication interface 210 and the fourth communication interface 1210.

[0113] In one embodiment, the first communication interface 210 in the input / output interface module 200 and the fourth communication interface 1210 in the host processor module 410 may be connected via a cable.

[0114] According to an embodiment of the present application, when the host processor module is already provided with a baseboard management control module, that is, the host processor module already has the management function of the baseboard management control module, the input and output interface module can be used alone, and the communication and control between the server and the external device can be realized through the electrical connection between the first communication interface and the fourth communication interface.

[0115] According to an embodiment of the present application, the baseboard management control module is disposed inside the server, and the baseboard management control module is integrated with the host processor module.

[0116] According to an embodiment of the present application, the baseboard management control module has another application scenario. It is neither located on the host processor module nor located at the rear window of the server like the DC-SCM, but is located in the internal space of the server.

[0117] Figure 13 A schematic diagram of the layout of a baseboard management control module disposed inside a server according to an embodiment of the present application is shown.

[0118] like Figure 13 As shown, the baseboard management control module 100 is disposed inside the server.

[0119] Integration of the baseboard management control module 100 and the host processor module 410 means that the baseboard management control module 100 is installed on the host processor module 410 .

[0120] According to an embodiment of the present application, when the baseboard management control module is set inside the server, the baseboard management control module is integrated with the host processor module. Figure 9 The baseboard management control module shown in the same integration with the host processor module, but with Figure 12 The baseboard management control module is shown with varying integration with the host processor module.

[0121] According to an embodiment of the present application, the baseboard management control module can also be set inside the server, thereby broadening the application scenarios of the baseboard management control module.

[0122] According to an embodiment of the present application, the baseboard management control module is provided with a fifth communication interface, and the input-output interface module is also used to electrically connect to the fifth communication interface through the first communication interface; or the host processor module is provided with a sixth communication interface, and the input-output interface module is also used to electrically connect to the sixth communication interface through the first communication interface.

[0123] According to an embodiment of the present application, the baseboard management control module 100 is disposed within the server. When a fifth communication interface is provided in the baseboard management control module 100, the input / output interface module can be electrically connected to the fifth communication interface via the first communication interface to enable communication between the baseboard management control module and the input / output interface module, thereby achieving management, control, and security functions for the server.

[0124] According to an embodiment of the present application, when a sixth communication interface is provided on the host processor module, the input-output interface module can be electrically connected to the sixth communication interface through the first communication interface to realize communication between the baseboard management control module and the input-output interface module, thereby realizing management, control and security functions of the server.

[0125] According to an embodiment of the present application, since the baseboard management control module and the input / output interface module are separated, the baseboard management control module can be set inside the server to broaden the application scenarios.

[0126] According to an embodiment of the present application, the server includes the control device mentioned in the above embodiment, which includes a separate baseboard management control module and an input / output interface module.

[0127] According to an embodiment of the present application, the baseboard management control module in the server can be as follows Figure 1 or Figure 6 As shown, the input and output interface modules in the server can be Figure 2 shown.

[0128] Specifically, in order to realize the management, control and security functions of the server, the connection relationship between the baseboard management control module, the host processor module and the input and output interface module can be as follows: Figure 4 、 Figure 5 、 Figures 7 to 12 shown.

[0129] According to the embodiments of the present application, due to the provision of two separate independent modules, namely the baseboard management control module and the input / output interface module, the baseboard management control module and the input / output interface module can be electrically connected to form a complete DC-SCM. Alternatively, they can be used separately in scenarios requiring only the baseboard management control module or the input / output interface module, thereby meeting the needs of different application scenarios. Thus, the baseboard management control module and the input / output interface module can be used together or independently to implement server management, monitoring, and security functions, as well as communication and control between the server and external devices.

[0130] According to an embodiment of the present application, when the baseboard management control module is disposed inside the server, an input / output interface module is disposed on the front window or the rear window of the server.

[0131] According to the embodiments of the present application, the input / output interface module 200 serves as the interface for interaction between the server and external devices. When the baseboard management control module 100 is installed inside the server, the baseboard management control module and the input / output interface module need to be separated. Therefore, the baseboard management control module is installed in the host processor module, and the input / output interface module can be flexibly installed in the front or rear window of the server according to different server configuration requirements.

[0132] Figure 14 A schematic diagram showing the connection between a baseboard management control module provided with a fifth communication interface and an input / output interface module according to an embodiment of the present application is shown.

[0133] like Figure 14 As shown, when a fifth communication interface 1410 is provided on the baseboard management control module 100, the input / output interface module 200 located on the front window or rear window of the server is also used to be electrically connected to the fifth communication interface 1410 through the first communication interface, thereby realizing communication between the baseboard management control module 100 and the input / output interface module 200.

[0134] Figure 15 A schematic diagram shows a host processor module provided with a sixth communication interface connected to an input / output interface module according to an embodiment of the present application.

[0135] like Figure 15 As shown, when the sixth communication interface 1510 is provided on the host processor module 410, the input-output interface module 200 located on the front window or rear window of the server is also used to be electrically connected to the sixth communication interface 1510 through the first communication interface, thereby realizing communication between the baseboard management control module 100 and the input-output interface module 200.

[0136] Therefore, if the I / O interface module is coupled to the baseboard management control module, this flexibility is lost because the I / O interface module needs to be placed on the front or rear window of the server. In this case, the baseboard management control module has limited space and cannot be placed inside the server. Furthermore, if a traditional DC-SCM is used, it is impossible to flexibly place the DC-SCM on the front or rear window of the server to achieve flexible configuration of the front and rear I / O interfaces. Because the DC-SCM and the host processor module exchange multiple signals, it is impossible to have an interface for interaction with the DC-SCM on both the front and rear of the host processor module, otherwise the signal quality will be greatly affected.

[0137] According to the embodiment of the present application, since the baseboard management control module and the input / output interface module are separated, the input / output interface module can be flexibly installed on the front window or the rear window of the server according to different server configuration requirements.

[0138] Based on the above, it can be seen that the control device of the present application includes a separate baseboard management control module and an input-output interface module. By designing the baseboard management control module and the input-output interface module separately, the control device of the present application can be flexibly configured according to actual needs to meet the needs of different application scenarios. At the same time, the modular design of the present application allows the reuse of a common module design in different projects and architectures, reducing the complexity and cost of hardware development.
