The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

It should be understood that, in the various embodiments of the present application, the size of the serial number of each implementation process does not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

Before further detailed description of the embodiments of the present application, terms and expressions referred to in the embodiments of the present application will be described, and the terms and expressions referred to in the embodiments of the present application will be used for the following explanation.

1) A processor core: is the most core part inside the processor and can also be called as the processor core.

2) A processor: including one or more processor cores, and other components or devices such as memory.

3) Assembly line: the method is an implementation technology for overlapping execution of a plurality of instructions, each step in a flow line completes one part of the instructions, each step is called as a flow line stage or a flow line section, and the flow line stages are connected in series to form the flow line; instructions enter at one end of the pipeline and exit at the other end of the pipeline through the pipeline stages; each pipeline corresponds to a task.

For the processing flow of an instruction in a pipeline, as shown in fig. 1, the life cycle of an instruction in a pipeline includes: fetching, decoding, executing, accessing and writing back. Instruction fetching refers to a process of reading an instruction from a memory. Instruction decoding refers to a process of translating an instruction fetched from a memory, and after decoding, an operand Register index required by the instruction is obtained, and the operand can be read from a general Register File (Register File) by using the operand Register index. The type of computation to be performed after Instruction decode is known and the required operands have been read from the general purpose register set, then Instruction execution (Instruction execution) follows. Instruction execution refers to the process of actually operating on an instruction. For example, if the instruction is an add operation instruction, the operand is added; if the instruction is a subtraction operation, the operand is subtracted. The most common component in the "execute" stage is the ALU, which is a hardware functional unit that implements specific operations. Memory access refers to the process by which memory access instructions read data from memory or write data to memory. Write-back refers to the process of writing back the result of instruction execution to the general register set, if it is a normal operation instruction, the result value comes from the result of the 'execution' stage calculation; if the instruction is a memory read instruction, the result comes from data read from the memory in the 'access' stage.

The resources allocated to a processor core refer to the resources used for the various pipeline stages of the execution pipeline. For example: the resources allocated to the processor core can be branch prediction resources, instruction fetching resources, decoding resources, renaming resources, execution resources and the like; the execution resources may include at least one or more of arithmetic resources, register resources, and memory resources. The memory resources may include buffers and memory, and the buffers may include at least one or more of an L1 buffer, an L2 buffer, and an L3 buffer. The memory may be any type of memory such as a flash memory. The transcoding resources may include at least one transcoder. The renaming resource may include at least one register.

In the related art, a piece of computer equipment internally comprises a plurality of processor cores, and resources in the computer equipment are allocated by taking the processor cores as granularity; specifically, resources corresponding to each processor core are allocated to each processor core; the resources among the processor cores are independent from one another, and the processor core A cannot use the resources allocated to the processor core B when executing the task; likewise, processor core B cannot accommodate the resources allocated to processor core a while executing tasks. The applicant finds that when the resources in the computer device are allocated by taking the processor cores as the granularity, at least the following problems exist: when a pipeline executed by a certain processor core needs stronger resources, the resources allocated to the processor core cannot meet the requirements of the pipeline on the resources, and the task execution efficiency is low; when a pipeline executed by a certain processor core needs weak resources, part of the resources allocated to the processor core are idle, and the resources cannot be effectively utilized.

As shown in fig. 2, an optional processing flow of the resource management method provided in the embodiment of the present application at least includes the following steps:

s101, a resource management unit in the electronic equipment determines resources required by the task to be processed according to the task to be processed.

In the embodiment of the application, the resource management unit in the electronic device determines the resources required by the task to be processed according to the task to be processed, and can allocate the resources according to the requirement of the task to be processed on the resources, so that the problem of resource waste in the related art is avoided, and the resource utilization rate is improved.

In some embodiments, a pending task may refer to a task to be executed by a processor core within an electronic device, one pending task corresponding to a pipeline.

In some optional embodiments, the resource management unit in the electronic device determines a schematic diagram of resources required by the task to be processed according to the task to be processed, as shown in fig. 3, at least including the following steps:

s101a, the resource management unit in the electronic equipment determines the information of the task to be processed.

In some embodiments, the information of the pending task may include at least one or more of: the type of the task to be processed, the name of the task to be processed, the application program corresponding to the task to be processed and the execution period of the task to be processed.

S101b, the resource management unit determines the resource needed by the task to be processed based on the information of the task to be processed.

In some embodiments, the resource management unit determines the resources required by the task to be processed based on the information of the task to be processed, including: the resource management unit determines the type, intensity (size), and the like of resources required by the task to be processed based on the information of the task to be processed.

S102, the resource management unit searches resources matched with the resources needed by the task to be processed in the resources recovered in the first time interval.

In some embodiments, the resources recovered for the first time interval are: and responding to the completion of the all execution of the historical tasks corresponding to the resources, and releasing the resources for executing the historical tasks in a first time zone away from the current time.

Specifically, the historical task may be a task that has been completely executed before the current time, or may be a task that has been partially executed before the current time. The first time interval at the current time is a time period before the current time, for example, an hour before the current time, tens of minutes before the current time, seconds before the current time, or tens of milliseconds before the current time. In this embodiment, when all the historical tasks are executed, the resources corresponding to the historical tasks are released, and meanwhile, the resource management unit may recycle the resources corresponding to the historical tasks. When all the historical tasks are executed or after the historical tasks are executed, if the resources are the resources released in the first time interval at the current moment for executing the historical tasks, the resources can be regarded as the resources recycled by the resource management unit in the first time interval.

In this embodiment, after the pipeline corresponding to the historical task is completely executed, the resource corresponding to the historical task is released, so that when an error occurs in one or more pipeline stages of the pipeline corresponding to the historical task, the resource corresponding to the historical task can be reused to execute the task in the one or more pipeline stages again, and the successful execution of the historical task can be ensured. Meanwhile, the resources which are released in the first time interval from the current time and used for executing the historical tasks are used as the resources recovered in the first time interval in response to the completion of the execution of all the historical tasks corresponding to the resources, so that the resources in the nearest time interval at the current time can be obtained, various resources for executing the historical tasks can be simultaneously obtained and used for executing the tasks to be processed, and the resources recovered before the first time interval are controlled to be in a dormant state.

In some embodiments, the resources recovered for the first time interval are: and responding to the completion of the execution of the historical task part corresponding to the resource, and releasing the resource corresponding to the executed historical task in a first time zone away from the current time.

In this embodiment, when the execution of the history task is completed partially, the resource corresponding to the executed history task is released, and meanwhile, the resource management unit may recycle the resource corresponding to the executed history task. When the historical task part is executed or after the historical task part is executed, if the resource of the executed historical task is released in the first time interval at the current moment, the resource can be considered to be the resource recycled by the resource management unit in the first time interval.

In this embodiment, after the pipeline part corresponding to the historical task is executed, the resource corresponding to the completed historical task is released, so that the resource corresponding to the completed historical task can be released in time, and the utilization rate of the resource is improved. Meanwhile, the resources of the executed historical tasks released in a first time interval from the current time in response to the completion of the execution of the historical task part corresponding to the resources are taken as the resources recovered in the first time interval, the resources in the nearest time interval at the current time can be obtained and used for the execution of the tasks to be processed, and the resources recovered before the first time interval are controlled to be in a dormant state.

In this embodiment, the process of recovering the resource corresponding to the historical task will be described according to the following steps:

in step S201, a resource management unit in the electronic device receives a task end instruction sent by a processor core in the electronic device.

In some embodiments, the resource management unit receives a task end instruction sent by the processor core; the task ending instruction is used for representing that the task executed by the processor core is completely ended or is not completely ended (partially completed), and instructing the resource management unit to recycle the resource which is completely executed.

For example, if the task ending instruction represents that the tasks executed by the processor cores are all ended, the resource management unit is instructed to recycle all the resources allocated by the resource management unit; or, if the task ending instruction represents that the task part executed by the processor core is completed, the resource management unit is instructed to recycle the resource which is completed.

The executed resources (or sub-resources) comprise resources (or sub-resources) corresponding to the executed tasks in the process of executing the tasks by the processor cores; for example, the task includes instruction fetching, decoding, executing, accessing and writing back, and after the processor core completes the instruction fetching, the resource (or sub-resource) required for the instruction fetching is the resource for completion of the execution; or after the processor core finishes the instruction fetching and the decoding, the resources (or sub-resources) required by the instruction fetching and the decoding are the resources finished by the execution.

Step S202, the resource management unit determines, based on the task ending instruction, a resource for executing a task corresponding to the task ending instruction.

In some embodiments, in response to the task not completely ending, the resource management unit determines at least one sub-resource corresponding to the task ending instruction; the resource management unit confirms that at least one sub-resource is a resource for executing a task corresponding to the task ending instruction; and at least one sub-resource comprises a sub-resource which is executed in all sub-resources for executing the task.

In specific implementation, the task ending instruction may be periodically sent to the resource management unit by the processor core in the process of executing the task; or the processor core sends the executed subtasks to the resource management unit in the process of executing the tasks; the task ending instruction may include a progress of the processor core to execute the task.

Further, in specific implementation, in response to that the task ending instruction is periodically sent to the resource management unit by the processor core in the process of executing the task, the resource management unit determines, based on the task ending instruction, that the sub-resource corresponding to the executed sub-task in the task is the resource for executing the task corresponding to the task ending instruction. For example, the task comprises five subtasks, namely instruction fetching, decoding, execution, access and write-back, and when the processor core executes and does not execute to complete the access, the processor core periodically sends a task ending instruction to the resource management unit; and the resource management unit confirms the sub-resources required by value taking, decoding and execution before access storage as the resources of the task corresponding to the task ending instruction.

Or, in specific implementation, in response to that the task ending instruction is sent to the resource management unit by the processor core in the process of executing the task, the resource management unit determines, based on the task ending instruction, that at least one sub-resource executed and completed in the task is a resource for executing the task corresponding to the task ending instruction. For example, the task comprises instruction fetching, decoding, execution, memory access and write back, and when the processor core completes the memory access, a task ending instruction is sent to the resource management unit; the resource management unit confirms that the sub-resources required by the access and storage are the resources of the task corresponding to the task ending instruction; obviously, after the sub-resources required by the value taking, decoding and execution are finished, the task ending instruction sent by the processor core is recycled.

In some embodiments, in response to the task being completely finished, the resource management unit determines all sub-resources corresponding to the task-finished instruction; the resource management unit confirms that all the sub-resources are resources for executing the task corresponding to the task ending instruction; and all the sub-resources comprise sub-resources which are executed in all the resources for executing the task.

In specific implementation, the task ending instruction may be periodically sent to the resource management unit by the processor core in the process of executing the task; or the processor core sends the executed part to the resource management unit in the process of executing the task; the processor core can also send the data to the resource management unit after executing all tasks; the task ending instruction may include a progress of the processor core executing the task.

Further, in specific implementation, in response to that the task ending instruction is sent by the processor core in the process of executing the task (including sending periodically or sending after completing one subtask), the resource management device may temporarily suspend the task ending instruction, and after all subtasks included in the task are completed, confirm that all the sub resources corresponding to the task are resources for executing the task corresponding to the task ending instruction; or, in response to the task ending instruction being sent by the processor core after the task is completely ended, the resource management unit determines that all sub-resources corresponding to the task are resources for executing the task corresponding to the task ending instruction.

In step S203, the resource management unit recovers the resource.

In some embodiments, the resource management unit reclaims resources such that the reclaimed resources may or may not be allocated when subsequently allocating resources for the pending task.

In this way, the resource management unit in the electronic device receives a task ending instruction sent by the processor core in the electronic device; the resource management unit determines to execute the resource of the task corresponding to the task ending instruction based on the task ending instruction; the resource management unit recovers resources; the resource is distributed to a pipeline corresponding to the task to be processed by the resource management unit according to the task; under the condition that the tasks are completely finished or the subtasks are finished, the resource management unit can recycle the resources (or the sub-resources) which are finished according to the task finishing instruction, so that the resource allocation and execution of other tasks are facilitated, and the resource utilization rate and the task execution efficiency are improved.

In some embodiments, the optional recycling process for the resources corresponding to the historical tasks further includes the following steps:

in step S200, a processor core in the electronic device sends a task ending instruction to a resource management unit in the electronic device.

In some embodiments, a processor core within an electronic device sends a task end instruction to a resource management unit within the electronic device; the task ending instruction is used for the resource management unit to recycle and execute the resources of the task corresponding to the task ending instruction.

In some embodiments, in the case that the task is not completely ended, the processor core sends a task ending instruction to the resource management unit, so that the resource management unit recovers sub-resources that are completely executed in all resources for executing the task; alternatively, when all tasks are completed, the processor core transmits a task completion instruction to the resource management unit to cause the resource management unit to collect all resources for executing the tasks.

During specific implementation, the processor core can periodically send a task ending instruction to the resource management unit in the task execution process; or, the processor core may also send a task end instruction to the resource management unit for the executed subtasks in the task execution process; alternatively, the processor core may send a task end instruction to the resource management unit after executing all tasks.

Therefore, the processor core in the electronic equipment flexibly sends a task ending instruction to the resource management unit in the electronic equipment according to the task execution condition, so that the resource management unit can flexibly recover part or all resources, resource allocation and execution of other tasks are facilitated, and the resource utilization rate and the task execution efficiency are improved.

In some embodiments, after the resource management unit determines, for the task to be processed, the type of the resource required by the task to be processed and the strength (size) of the resource, the resource management unit searches for a resource matching the resource required by the task to be processed from among the resources recovered in the first time interval, including at least the following steps: searching resources with the same type as the resources required by the task to be processed in the resources recovered in the first time interval; and/or searching resources which are larger than or equal to the size of the resources required by the task to be processed in the resources recycled in the first time interval.

Specifically, as an example, if the branch prediction sub-resource, the instruction fetch sub-resource, the decode sub-resource, the rename sub-resource, and the execution sub-resource corresponding to the historical task are released in the first time interval, the resources recovered in the first time interval include the branch prediction sub-resource, the instruction fetch sub-resource, the decode sub-resource, the rename sub-resource, and the execution sub-resource released by the historical task. The resource management unit determines the type of the resource required by the task to be processed, and comprises the following steps: and the sizes of the branch prediction sub-resources, the instruction fetching sub-resources, the decoding sub-resources and the execution sub-resources are larger than the size of the resources required by the task to be processed, so that the resources with the size matched with the resources required by the task to be processed can be randomly selected from the branch prediction sub-resources, the instruction fetching sub-resources, the decoding sub-resources and the execution sub-resources and are distributed to the task to be processed.

In this embodiment, the asset management unit searches for a resource of the same type as a resource required by a task to be processed in the resources recovered in the first time interval; and/or searching for resources with the size larger than or equal to the size of the resources required by the task to be processed in the resources recovered in the first time interval, performing resource matching according to the type and size of the resources required by the task to be processed, and quickly matching the task to be processed with proper resources.

In some embodiments, a specific process of the resource management unit searching for a resource matching with a resource required by a task to be processed in the resources recovered in the first time interval is shown in fig. 4, and includes:

in step S102a, the resource management unit in the electronic device determines a resource allocation policy based on the resources required by the task to be processed.

In step S102b, the resource management unit allocates resources for the to-be-processed task in the resources recovered in the first time interval based on the resource allocation policy.

With respect to step S102a, the determining, by the resource management unit, a specific implementation process of the resource allocation policy based on the resource required by the task to be processed may include: the resource management unit first determines a resource allocation policy based on the strength of the resources required by the task to be processed.

In some embodiments, the resources required for a task may be divided into a number of different intensity levels based on intensity. As an example, resources required by a task are divided into two levels based on intensity, and in response to that the intensity of the resources required by the task to be processed meets a first condition, the resource allocation policy is determined to be a first resource allocation policy; and determining the resource allocation strategy to be a second resource allocation strategy in response to the fact that the strength of the resources required by the task to be processed meets a second condition. The resources with the strength meeting the first condition are weak resources, and the resources with the strength meeting the second condition are strong resources; for weak resources, dividing available resources recovered in a first time interval based on a first resource allocation strategy; for strong resources, the available resources recovered for the first time interval are partitioned based on a second resource allocation policy. As an example, the first condition may be that the strength of the resource is less than a first strength threshold, the second condition may be that the strength of the resource is greater than a second strength threshold, the first strength threshold and the second strength threshold both being used to characterize the strength or size of the resource, the first strength threshold being less than or equal to the second strength threshold, wherein the size of the resource allocated based on the first resource allocation policy is less than the size of the resource allocated based on the second resource allocation policy.

In the above, the resource required by the task is divided into two levels based on the strength, and in specific implementation, the resource required by the task may be divided into three levels or more than three levels based on the strength, which is not limited in the embodiment of the present application. And the resource allocation strategies corresponding to all the intensity levels are different.

Dividing available memory resources recycled in the first time interval into N parts based on a first resource allocation strategy, wherein the size of each part of memory resources is X; dividing the available memory resources recycled in the first time interval into M parts based on a second resource allocation strategy, wherein the size of each part of the memory resources is Y; wherein N is more than M, and X is less than Y.

In the above description, taking the average division of the resources (such as available memory resources) recovered in the first time interval into multiple parts as an example, in a specific implementation, the resources recovered in the first time interval may also be unevenly divided, for example, the multiple parts of the resources obtained by dividing the resources recovered in the first time interval are different in size, or the parts of the resources obtained by dividing the resources recovered in the first time interval are the same in size and different in size.

For step S102b, the specific implementation process of the resource management unit allocating resources for the task to be processed based on the resource allocation policy may include: for each type of resource recovered in the first time interval, the resource management unit divides each type of resource into at least one sub-resource pool based on the resource allocation strategy; and determining that the resource in one of the at least one sub-resource pool is the resource required by the task to be processed.

In some embodiments, each type of resource recycled for the first time interval may include branch prediction resources, instruction fetching resources, transcoding resources, renaming resources, arithmetic resources, register resources, and memory resources.

Taking the example that the resource recovered in the first time interval is a branch prediction resource, the resource management unit divides the branch prediction resource into one or more branch prediction sub-resource pools based on the resource allocation policy, and the size of the resource included in each branch prediction sub-resource pool is the same or different. The resource management unit selects one branch prediction sub-resource pool meeting the requirement of the task to be processed from the plurality of branch prediction sub-resource pools, and resources in the selected branch prediction sub-resource pool are resources used for performing branch prediction on the task to be processed.

The above description has been made of a process of determining a resource for performing branch prediction, taking only a branch prediction resource as an example. In specific implementation, the process of determining resources for instruction fetching, decoding, renaming, calculating, storing, accessing, and the like is the same as the process of determining resources for branch prediction, and details are not described in the embodiments of the present application.

In the embodiment of the application, each type of resource recovered in a first time interval is divided into a resource pool, a resource allocation strategy is determined based on the strength of the resource required by a task to be processed, and each resource pool is divided into a plurality of sub-resource pools with the same or different sizes according to the resource allocation strategy; the method and the device can distribute the required resources for the tasks from the plurality of sub-resource pools according to the requirements of the tasks. Therefore, the execution efficiency of the tasks is improved, the utilization rate of resources is improved, and the performance of the electronic equipment is improved.

Based on the flow shown in fig. 4, it can be understood that in the embodiment of the present application, each type of resource recovered in the first time interval is divided into one resource pool, and a resource required for executing the task to be processed is allocated to the task to be processed in the resource pool recovered in the first time interval according to the resource required by the task to be processed.

In specific implementation, the resource division diagram recovered in the first time interval is as shown in fig. 5: dividing branch prediction resources recovered in a first time interval into a branch prediction resource pool, dividing fetch resources recovered in the first time interval into a fetch resource pool, dividing decoding resources recovered in the first time interval into a decoding resource pool, dividing renaming resources recovered in the first time interval into a renaming resource pool, and dividing execution resources recovered in the first time interval into an execution resource pool; wherein the execution resources may include: one or more of register resources, memory resources, and computational resources. All the resource pools are connected through a connection network; the connection network may be a hardware network based on switch control, or may be any other network, which is not limited in the embodiments of the present application.

In the resource division diagram shown in fig. 5, the resource management unit performs resource management on all resource pools; in a specific implementation, the resource management unit may further include a plurality of resource management sub-units, and each resource management sub-unit performs resource management on different resource pools. As an example, the resource management unit includes a branch prediction resource sub-management unit, an instruction resource sub-management unit, a decode resource sub-management unit, a rename resource sub-management unit, and an execution resource sub-management unit; the branch prediction resource sub-management unit is used for performing resource management on resources in a branch prediction resource pool, the fetch resource sub-management unit is used for performing resource management on the resources in the fetch resource pool, the decoding resource sub-management unit is used for performing resource management on the resources in the decoding resource pool, the renaming resource sub-management unit is used for performing resource management on the resources in the renaming resource pool, and the execution resource sub-management unit is used for managing the resources in the execution resource pool.
