[0030] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. The described embodiments should not be regarded as limiting the present disclosure. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0031] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0032] In the following description, the terms "first\second" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing the embodiments of the present disclosure and are not intended to limit the present disclosure.

[0034] It should be understood that in the various embodiments of the present disclosure, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0035] Before further describing the embodiments of the present disclosure in detail, the nouns and terms involved in the embodiments of the present disclosure are described. The nouns and terms involved in the embodiments of the present disclosure are subject to the following interpretations.

[0036] 1) Processor core: It is the core part of the processor and can also be called the processor core.

[0037] 2) Processor: includes one or more processor cores, as well as other components or devices such as memory.

[0038] 3) Pipeline: It is an implementation technology that overlaps the execution of multiple instructions. Each step in the pipeline completes part of the instruction. Each step is called a pipeline stage or pipeline segment. The pipeline stages are connected to form a pipeline. The instruction enters at one end of the pipeline, passes through these pipeline stages and exits at the other end of the pipeline. Each pipeline corresponds to a task.

[0039] The processing flow of instructions in a pipeline, such as Figure 1 As shown in the figure, the life cycle of an instruction in a pipeline includes: instruction fetch, decoding, execution, memory access and write back. Among them, instruction fetch refers to the process of reading instructions from the memory. Instruction decoding refers to the process of translating the instructions fetched from the memory. After decoding, the operand register index required by the instruction is obtained, and the operand can be read from the general register file using this index. After instruction decoding, the type of calculation required is known, and the required operand has been read from the general register file, then the instruction execution (Instruction Execute) is performed. Instruction execution refers to the process of actually operating the instruction. For example, if the instruction is an addition instruction, the operand is added; if it is a subtraction instruction, the operand is subtracted. The most common component in the "execution" stage is ALU, which is the hardware functional unit for implementing specific operations. Memory access refers to the process of memory access instructions reading data from the memory or writing data into the memory. Write back refers to the process of writing the result of instruction execution back to the general register group. If it is a normal operation instruction, the result value comes from the result calculated in the "execution" stage; if it is a memory read instruction, the result comes from the data read from the memory in the "memory access" stage.

[0040] The resources allocated to the processor core refer to the resources used to execute each pipeline stage of the pipeline. For example, the resources allocated to the processor core may be branch prediction resources, instruction fetch resources, decoding resources, renaming resources, execution resources, etc., wherein the execution resources may include at least one or more of computing resources, register resources, and memory resources. Among them, the memory resources may include a cache and a memory, and the cache may include at least one or more of an L1 cache, an L2 cache, and an L3 cache. The memory may be any type of memory such as a flash memory. The decoding resources may include at least one decoder. The renaming resources may include at least one register.

[0041] In the related art, a computer device includes multiple processor cores, and the resources in the computer device are allocated based on the processor core; specifically, the resources corresponding to each processor core are allocated to each processor core; the resources between the processor cores are independent of each other, and processor core A cannot use the resources allocated to processor core B when executing a task; similarly, processor core B cannot use the resources allocated to processor core A when executing a task. The inventor found that when the resources in the computer device are allocated based on the processor core, there are at least the following problems: when the pipeline executed by a processor core requires stronger resources, the resources allocated to the processor core cannot meet the resource requirements of the pipeline, and the efficiency of executing the task is low; when the pipeline executed by a processor core requires weaker resources, some of the resources allocated to the processor core are idle and the resources cannot be effectively used.

[0042] In response to the problems of low resource utilization and low task execution efficiency in resource allocation in related technologies, the embodiments of the present disclosure provide a resource allocation method, an electronic device and a computer-readable storage medium, which can improve resource utilization and the execution efficiency of tasks to be processed.

[0043] An optional processing flow of the resource allocation method provided in the embodiment of the present disclosure is as follows: Figure 2 As shown, at least the following steps are included:

[0044] Step S101: The resource management unit in the electronic device determines the resources required by the pipeline corresponding to each task to be executed according to each task to be executed.

[0045] For example, a pending task may refer to a task to be executed by a processor core in an electronic device, and one pending task corresponds to one pipeline.

[0046] For example, the resources required for each task to be executed may refer to: the number of resources required for each pipeline stage or pipeline segment of each step when executing a pipeline of the task to be executed and completing the corresponding instructions.

[0047] For example, the resources include one or more of branch prediction resources, instruction fetch resources, decoding resources, renaming resources, or execution unit resources.

[0048] Step S102: The resource management unit determines the resource allocation priority of the pipeline corresponding to the task to be executed based on the resources required by the task to be executed.

[0049] In some embodiments, the resource management unit obtains resources in the resource pool and allocates the resources according to the resource allocation priority. The electronic device includes multiple types of resource pools, and each type of resource pool includes multiple sub-resource pools. The connection method of multiple types of resource pools and the division method of sub-resource pools are described below.

[0050] In some embodiments, for the same type of resources, the resource allocation priority of allocating the type of resources to the tasks to be executed is determined according to the number of resources required by each task to be executed. Among multiple tasks to be executed, each assembly line has different requirements for the same type of resources, so the resource allocation priority can be set according to the demand for resources.

[0051] For example, Figure 3 As shown, step S102 at least includes the following steps:

[0052] Step S102-a1: Determine that the resource allocation priority of allocating this type of resource to the to-be-executed task requiring the largest number of resources is the highest;

[0053] Step S102 - a2 : Determine that the resource allocation priority of allocating this type of resource to the to-be-executed task requiring the least number of resources is the lowest.

[0054] For example, there are two tasks to be executed, namely, a first task to be executed and a second task to be executed. When allocating resources, it is necessary to allocate resource priorities according to the number of resources required by the first task to be executed and the second task to be executed. For example, for the same type of resources, such as branch prediction resources, the number of resources required to execute the first task to be executed pipeline is greater than the number of resources required to execute the second task to be executed pipeline. In this case, the resource allocation priority is set as follows: the priority of the first task to be executed is greater than the priority of the second task to be executed.

[0055] By adopting the above resource allocation method, resources are allocated preferentially to pending tasks that require a large number of resources, which is conducive to full utilization of resources. That is, according to the resource allocation priority, tasks with lower priorities require fewer resources, while when the number of resources in the resource pool is fixed, there is a higher probability of matching fewer resources with pending tasks that require a small number of resources.

[0056] In some embodiments, for the same type of resources, the resource allocation priority of allocating the type of resources to the tasks to be performed is determined based on the number of resources that can be satisfied by the available resources of the electronic device that are required for each task to be performed. Among multiple tasks to be performed, the number of resources in each type of resource pool is fixed, so the resource allocation priority can be set based on the number of resources that can be satisfied by the available resources for each task to be performed.

[0057] For example, Figure 4 As shown, step S102 at least includes the following steps:

[0058] Step S102-b1: Determine among the available resources of the electronic device that the resource allocation priority of the task to be executed that can meet the largest number of required resources is the lowest;

[0059] Step S102-b2: Determine that among the available resources of the electronic device, the resource allocation priority of the task to be executed that can meet the minimum required resource quantity is the highest.

[0060] For example, when a large number of resources are available to meet the needs of the current task to be executed, it means that there are more sub-resource pools that can meet the needs of the current task to be executed, and when a small number of resources are available to meet the needs of the current task to be executed, it means that there are fewer sub-resource pools that can meet the needs of the current task to be executed. The resource allocation priority can be set according to such situations, that is, the smaller the number of resources available to meet the needs, the higher the resource allocation priority, and vice versa.

[0061] For example, there are two tasks to be executed, namely, a first task to be executed and a second task to be executed. For example, the first task to be executed and the second task to be executed require different quantities of a type of resources, such as branch prediction resources. For example, the quantity of a type of resources required to meet the needs of the first task to be executed is less than the quantity of a type of resources required to meet the needs of the second task to be executed, for example, the quantity of a type of resources required to meet the needs of the first task to be executed is 3, and the quantity of a type of resources required to meet the needs of the second task to be executed is 4. In this case, the resource allocation priority is set as follows: the priority of the first task to be executed is greater than the priority of the second task to be executed.

[0062] With the above resource allocation method, if the number of resources that meet the task to be executed is small, it means that the types of resources that are adapted to the task to be executed are even smaller. Therefore, in order to enable this type of task to be executed to obtain adapted resources, resource allocation needs to be prioritized, thereby making resource allocation more reasonable.

[0063] In some embodiments, for the same type of resources, the resource allocation priority of allocating this type of resources to the tasks to be executed is determined based on the number of resources required for each task to be executed and the number of resources available in the electronic device that can meet the requirements of each task to be executed.

[0064] For example, when allocating resources, the priority of the number of resources required for each task to be executed is higher than the priority of the number of resources in the available resources that can meet the needs of each task to be executed, or the priority of the number of resources required for each task to be executed is lower than the priority of the number of resources in the available resources that can meet the needs of each task to be executed.

[0065] Step S103: allocating resources to the pipeline corresponding to each task to be executed according to the resource allocation priority, and the resources are used by the processor core in the electronic device to execute the task to be executed.

[0066] In some embodiments, for each type of resource in the electronic device, the resource management unit divides each type of resource into at least one sub-resource pool, determines a resource in a sub-resource pool of each type of resource as a target resource, and obtains the corresponding target resource according to the resource allocation priority.

[0067] Taking the case where the resources in the electronic device are branch prediction resources, the resource management unit divides the branch prediction resources into one or more branch prediction sub-resource pools, and the size of the resources included in each branch prediction sub-resource pool is the same or different, wherein the size of the resource can be interpreted as: a large resource includes a large number of resource units, while a small resource includes a small number of resource units. According to the resource allocation priority, the resource management unit selects a branch prediction sub-resource pool that meets the requirements of the task to be processed from the multiple branch prediction sub-resource pools, and the resources in the selected branch prediction sub-resource pool are the target resources for performing branch prediction on the task to be processed.

[0068] The above only takes the branch prediction resource as an example to illustrate the process of determining the target resource for branch prediction. In specific implementation, the process of determining the target resource for fetching, decoding, renaming, computing, storing, accessing, etc. is the same as the process of determining the target resource for branch prediction, and the embodiments of the present disclosure will not be described in detail.

[0069] In some embodiments, the resource management unit may be a program installed on the electronic device; or, the resource management unit may be a hardware component within the electronic device; or, the resource management unit includes a program installed on the electronic device and a hardware component within the electronic device.

[0070] In some embodiments, if the resource management unit is a program installed on an electronic device, the resource allocation method provided in the embodiment of the present disclosure is implemented in the form of software; wherein the program installed on the electronic device can be an application installed on the electronic device, or it can be a small program loaded by the application installed on the electronic device.

[0071] In a specific implementation, the program installed on the electronic device determines the resources required for each task to be executed, and determines the resource allocation priority of the task to be executed based on the resources required for the task to be executed; according to the resource allocation priority, the program installed on the electronic device sends the target resources to the corresponding hardware component in the electronic device, and the hardware component executes the task to be processed based on the target resources.

[0072] In other embodiments, if the resource management unit is a hardware component in an electronic device, the resource allocation method provided by the embodiment of the present disclosure is implemented in a hardware manner.

[0073] In a specific implementation, the hardware components in the electronic device determine the resources required for each task to be executed according to each task to be executed, determine the resource allocation priority of the task to be executed based on the resources required for the task to be executed, and execute the task to be processed based on the allocated target resources.

[0074] In some embodiments, if the resource management unit includes a program installed on an electronic device and a hardware component within the electronic device, it indicates that the resource allocation method provided by the embodiment of the present disclosure is implemented in a combination of software and hardware.

[0075] In a specific implementation, the hardware component in the electronic device sends each task to be executed to a program installed on the electronic device; the program installed on the electronic device determines the resources required for each task to be executed according to each task to be executed, and determines the resource allocation priority of the task to be executed based on the resources required for the task to be executed, and sends the allocated target resources to the corresponding hardware component in the electronic device, and the hardware component executes the task to be processed based on the target resources.

[0076] Alternatively, in a specific implementation, the hardware component within the electronic device sends each task to be executed to a program installed on the electronic device; the program installed on the electronic device determines the resources required for each task to be executed according to each task to be executed, determines the resource allocation priority of the task to be executed based on the resources required for the task to be executed, and sends the resource allocation priority to the corresponding hardware component in the electronic device, which allocates target resources to the task to be processed based on the resource allocation priority and executes the task to be processed based on the target resources.

[0077] based on Figure 2 From the resource allocation method shown, it can be understood that the embodiment of the present disclosure divides each type of resource included in an electronic device into a resource pool, and allocates the resources required to execute the task to be processed from the resource pool according to the resource allocation priority of the task to be processed.

[0078] In a specific implementation, a schematic diagram of resource division in an electronic device is shown as follows: Figure 5As shown: the branch prediction resources included in the electronic device are divided into a branch prediction resource pool, the instruction fetch resources included in the electronic device are divided into an instruction fetch resource pool, the decoding resources included in the electronic device are divided into a decoding resource pool, the renaming resources included in the electronic device are divided into a renaming resource pool, and the execution resources included in the electronic device are divided into an execution resource pool; wherein the execution resources may include: one or more of register resources, memory resources, and computing resources. For example, the resource pools are connected through a connection network; wherein the connection network may be a hardware network based on switch control, or may be any other form of network, which is not limited in the embodiments of the present disclosure.

[0079] Figure 5 In the resource partitioning diagram shown, the resource management unit performs resource management on all resource pools; in specific implementation, the resource management unit may also include multiple resource management sub-units, and each resource management sub-unit performs resource management on different resource pools. For example, the resource management unit includes a branch prediction resource sub-management unit, an instruction fetch resource sub-management unit, a decoding resource sub-management unit, a renaming resource sub-management unit, and an execution resource sub-management unit; wherein the branch prediction resource sub-management unit is used to perform resource management on resources in the branch prediction resource pool, the instruction fetch resource sub-management unit is used to perform resource management on resources in the instruction fetch resource pool, the decoding resource sub-management unit is used to perform resource management on resources in the decoding resource pool, the renaming resource sub-management unit is used to perform resource management on resources in the renaming resource pool, and the execution resource sub-management unit is used to manage resources in the execution resource pool.

[0080] against Figure 5 As shown in the resource partitioning diagram, according to different resource allocation strategies, each resource pool can be divided into Figure 6 As shown in the figure, multiple sub-resource pools of the same size, and Figure 7 Multiple sub-resource pools of different sizes are shown; among them, sub-resource pools of the same size refer to resources of the same type, and the sizes of resources included in each sub-resource pool are the same; sub-resource pools of different sizes refer to resources of the same type, and the sizes of resources included in multiple sub-resource pools are partially or completely different.

[0081] The following are Figure 6 A schematic diagram of dividing sub-resource pools based on resource allocation strategy is shown, and Figure 7 Another schematic diagram of dividing sub-resource pools based on resource allocation strategy is shown for explanation.

[0082] against Figure 6, based on the resource allocation strategy, each resource pool is divided into sub-resource pools in the way of organizing the minimum resources. The resources included in each sub-resource pool are the minimum units of resources of this type; in this way, the maximum number of sub-resource pools can be divided for each resource pool to support the maximum number of processor cores to execute the maximum number of tasks in parallel. For example, the branch prediction resource pool, instruction fetch resource pool, decoding resource pool, renaming resource pool and execution resource pool are all divided according to the minimum unit of resources. The branch prediction resource pool is divided into eight branch prediction sub-resource pools, the instruction fetch resource pool is divided into eight instruction fetch resource sub-resource pools, the decoding resource pool is divided into eight decoding sub-resource pools, the renaming resource pool is divided into eight renaming sub-resource pools, and the execution resource pool is divided into eight execution sub-resource pools. Each sub-resource pool can be used by one processor core to execute tasks, Figure 6 The resources shown can support eight processor cores executing eight tasks in parallel.

[0083] When each resource pool is divided into sub-resource pools, the number of sub-resource pools obtained by dividing each resource pool may be different; for example, the branch prediction resource pool is divided into eight branch prediction sub-resource pools, the instruction fetch resource pool is divided into six instruction fetch resource sub-resource pools, the decoding resource pool is divided into seven decoding sub-resource pools, the renaming resource pool is divided into eight renaming sub-resource pools, and the execution resource pool is divided into six execution sub-resource pools. In this scenario, five processor cores can be supported to execute six tasks in parallel.

[0084] In the disclosed embodiment, each resource pool is divided into sub-resource pools in a manner of organizing minimum resources, so that the resources within the electronic device can support the maximum number of processor cores to execute tasks in parallel, thereby improving the task parallel processing capability and thereby improving the performance of the electronic device.

[0085] against Figure 7 , based on the resource allocation strategy, each resource pool is divided into sub-resource pools in an organizational manner of different sizes. For the same type of resources, the sizes of the resources included in multiple sub-resource pools are partially or completely different. In this way, for the sub-resource pools with many resources, the processor core is supported to execute tasks with strong resource requirements, thereby improving the processing efficiency and processing capacity of the tasks. For example, each resource pool in the branch prediction resource pool, instruction fetch resource pool, decoding resource pool, renaming resource pool and execution resource pool is divided into sub-resource pools in an organizational manner of different sizes; taking the branch prediction resource pool as an example, the branch prediction resource pool is divided into five branch prediction sub-resource pools, and the sizes of the five branch prediction sub-resource pools are partially different and the same; Figure 7The size of the first branch prediction sub-resource pool is larger than the size of the second branch prediction sub-resource pool, and the sizes of the third branch prediction sub-resource pool, the fourth branch prediction sub-resource pool, and the fifth branch prediction sub-resource pool are the same. The first branch prediction sub-resource pool is suitable for tasks with high demand for branch prediction resources; the third branch prediction sub-resource pool, the fourth branch prediction sub-resource pool, and the fifth branch prediction sub-resource pool are suitable for tasks with low demand for branch prediction resources; the second branch prediction sub-resource pool is suitable for tasks with moderate demand for branch prediction resources (the demand for branch prediction resources is between the highest and lowest). Among them, the size of the sub-resource pool refers to the number of resources included in the sub-resource pool.

[0086] For a task, you can select any required sub-resource pool from each resource pool based on the demand for each type of resource according to the task to be executed and the resource allocation priority of the task to be executed; for example, under the current priority conditions, a first branch prediction sub-resource pool, a second instruction fetch sub-resource pool, a second decoding sub-resource pool, a third renaming sub-resource pool and a first execution sub-resource pool are allocated to a task to be executed.

[0087] In the disclosed embodiment, if there are idle or surplus resources in a sub-resource pool allocated for a task to be executed, the idle or surplus resources can be set to a sleep mode so that the idle or surplus resources are not used to execute the task, thereby reducing power consumption. The idle or surplus resources can also be cleared from the sub-resource pool and divided into other sub-resource pools so that the idle or surplus resources can be fully utilized and the resource utilization rate can be improved.

[0088] In the disclosed embodiment, each resource pool is divided into sub-resource pools in an organizational manner of different sizes, so that the resource management unit can allocate the required resources to the task according to the task's demand for each type of resource; thereby avoiding the problem of resource waste or insufficient resources to support the processor core in executing tasks due to allocating fixed resources to each processor core in the related technology, thereby improving the efficiency of task execution and resource utilization, and thereby improving the performance of the electronic device.

[0089] In the disclosed embodiment, the resource management unit in the electronic device determines the resources required for each task to be executed according to each task to be executed; the resource management unit determines the resource allocation priority of the task to be executed based on the resources required for the task to be executed; and resources are allocated to each task to be executed according to the resource allocation priority, and the resources are used by the processor core in the electronic device to execute the task to be executed. In this way, when there are multiple tasks to be executed, resources can be allocated according to the priority of the resource requirements of the tasks to be processed, which can not only avoid resource waste and improve resource utilization, but also improve the execution efficiency of the tasks to be executed.
