[0008] Furthermore, in the step of deploying the operating system according to the node role, the process of deploying the operating system includes: After the application is triggered on the local Master node, it is scheduled by the local Master node and assigned to the corresponding remote Slave node group for execution, and the results after execution are summarized.

[0009] Furthermore, the step of performing collaborative supervision in the operating system to obtain supervision results includes: The local Master node supervision process is as follows: After the system starts, the local Master node starts the real-time operating system, enables the supervisor role, and completes the initialization of other roles in the remote auxiliary system; Create virtual IO devices for remote communication and a resource list to store information about all roles in the system. Analyze the application's operating conditions based on the resource list and then use the scheduler to deploy the application. Finally, summarize the application's operating results returned by other roles to the shared memory area. The slave node group in the remote system completes the auxiliary part of the auxiliary supervision work: After the system starts, the remote slave node group completes hardware resource initialization, enables the supervised modules of the remote slave node group, creates their own local virtual IO devices to complete remote communication, creates a resource list to store all role information in the system, and updates the resource list information in real time according to its own real-time dynamics and synchronizes it to the local Master role.

Based on the supervision results, the system can isolate applications that pose security risks to prevent them from affecting the normal operation of other applications and nodes. This isolation mechanism can not only effectively resist external attacks and internal errors, but also ensure that the entire system can continue to operate stably when any node or application fails, and will not cause an overall collapse due to local failures. Therefore, the application security isolation measures of the present invention significantly improve the reliability and stability of hybrid heterogeneous systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts should fall within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a lightweight virtualization management method and related equipment for hybrid heterogeneous systems to solve the technical problem of how to uniformly manage multiple underlying hardware resources, meet the different needs of embedded applications and provide high-precision time response.

[0021] The present invention is described in further detail below with reference to the accompanying drawings: See also Figure 1 In one embodiment of the present invention, a lightweight virtualization management method for a hybrid heterogeneous system is provided, comprising: Step 1: obtain different nodes of the hardware layer in the hybrid heterogeneous system for initialization; Specifically, the initialization process includes: Establish connections with different nodes in the hardware layer through hardware interfaces; Use the preset initialization script to initialize hardware resources, load drivers, and perform basic configuration settings for different nodes.

[0022] The diversity of underlying hardware resources in this embodiment determines that the hybrid heterogeneous system must adopt a unified resource management method to achieve higher resource utilization, faster application deployment, lower power consumption costs and stronger load balancing.

[0023] In this embodiment, the related BSP software is adapted for different nodes of the hardware layer of the heterogeneous system to complete the initialization work at the hardware level.

[0024] Step 2: Classify the initialized nodes into different roles. Specifically, the node roles include a local Master node and several remote Slave node groups; The local Master node is used to complete the collaborative monitoring function; The remote slave node groups are used to complete the collaborative supervision and application calculation in response to the local master node.

[0025] Step 3: Deploy the operating system according to the node role; Specifically, the process of deploying an operating system includes: After the application is triggered on the local Master node, it is scheduled by the local Master node and assigned to the corresponding remote Slave node group for execution, and the results after execution are summarized.

[0026] In this embodiment, the operating system functions of the local Master node need to be as complete as possible, and the remote Slave node group runs the operating system microkernel or collaborative monitoring program (bare metal program).

[0027] This embodiment uses container technology to implement process-level virtualization and lightweight management among hybrid heterogeneous systems, so that they have higher resource utilization, faster application deployment, lower power consumption costs and stronger load balancing.

[0028] Step 4: Perform collaborative supervision in the operating system to obtain supervision results; Specifically, the steps of performing collaborative supervision in the operating system to obtain supervision results include: The collaborative management layer is located between the real-time operating system (RTOS) (or bare metal system) and the top-level application. It is used to complete device virtualization and resource management, complete system health monitoring and security management, and coordinate the scheduling of various roles in the system. The collaborative supervision model will run in each node role of the entire system. The local Master node performs the supervision process as follows: After the system starts, the local Master node starts the real-time operating system, enables the supervisor role, and completes the initialization of other roles in the remote auxiliary system; Create virtual IO devices for remote communication and a resource list to store information about all roles in the system. Analyze the application's operating conditions based on the resource list and then use the scheduler to deploy the application. Finally, summarize the application's operating results returned by other roles to the shared memory area. The slave node group in the remote system completes the auxiliary part of the auxiliary supervision work: After the system starts, the remote slave node group completes hardware resource initialization, enables the supervised modules of the remote slave node group, creates their own local virtual IO devices to complete remote communication, creates a resource list to store all role information in the system, and updates the resource list information in real time according to its own real-time dynamics and synchronizes it to the local Master role.

[0029] In this embodiment, the collaborative supervision middleware is used to complete the device virtualization, resource management, collaborative scheduling, health monitoring and other functions of the entire system. During the operation of the entire system, each hardware resource maintains the same resource list, including the model, memory, operating frequency, health status, etc. of all hardware in the system. Each node role updates the list resources regularly through the heartbeat function.

[0030] Step 5: Based on the supervision results, securely isolate the applications corresponding to the node roles to complete the lightweight virtualization management of the hybrid heterogeneous system.

[0031] Specific safety isolation measures include: Monitor the current role in applications of different roles for memory overflow and network attacks. If so, perform security isolation. Otherwise, continue normal operation. For different applications within the same role scope, runtime security middleware will be used to ensure the independence and non-interference between each application.

[0032] The adoption of the security isolation function in this embodiment ensures that the operation of any application will not interfere with other applications, and the failure of any application will not affect the overall function of the entire system, thereby maintaining the stability of the system.

[0033] according to Figure 2 The figure shows unified resource management for a hybrid heterogeneous system, primarily relying on collaborative supervision middleware. The local supervisor role runs the Master module, while the remote role runs the Slave module. The scheduler in the Master coordinates the application pool, distributing different applications to corresponding heterogeneous resources to achieve load balancing. The user interface in the Master includes a graphical user interface, editing and compiling functions, and resource viewing capabilities.

[0034] The collaborative supervision model is an abstract model of the collaborative supervision middleware, which is used to show the architecture of the entire middleware after it is deployed in the system. The local Master is responsible for completing the main control and coordination functions, and the remote Slave is responsible for responding to the local Master and maintaining a real-time resource status list, such as Figure 3 shown.

[0035] This embodiment provides a lightweight virtualization management method for hybrid heterogeneous systems. By acquiring and initializing different nodes at the hardware layer of a hybrid heterogeneous system, it achieves comprehensive integration and efficient utilization of hardware resources. Initialized nodes are classified according to their characteristics, and corresponding operating systems are deployed based on node roles. This allows for targeted configuration and optimization of various hardware resources, thereby avoiding idle and wasted resources and significantly improving resource utilization in the hybrid heterogeneous system.

The quad-core layout of the Cortex A53 is configured to simultaneously run two dual-core real-time systems, assuming both master and slave roles. The collaborative supervisor, acting as middleware, virtualizes local resources and obtains resource lists from remote roles in real time. The master coordinates application scheduling based on the resource list and balances load according to the resource availability of each role. The master coordinates and allocates application workloads based on the current resource utilization of each core, achieving load balancing and efficient resource utilization across the entire system.
