Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
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.
A processor core: is the most core part inside the processor and can also be called as the processor core.
A processor: including one or more processor cores, and other components or devices such as memory.
Assembly line: the method is an implementation technology for executing a plurality of instructions in an overlapping way, each step in a pipeline finishes one part of the instructions, each step is called as a pipeline stage or a pipeline section, and the pipeline stages are connected in front and back to form the pipeline; 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 pipeline.
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. The instruction fetch 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 an operand Register index required by the instruction is obtained after decoding, 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 flow of the actual operation 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. The memory access refers to a flow of reading data from a memory or writing data into the memory by a memory access instruction. Write-back refers to a 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; in the case of a memory read command, the result is data read from memory during the "access" phase.
An electronic device refers to an electronic device having a processor and employing at least one processor core in the processor.
A resource of an electronic device refers to a resource that may be allocated to a processor core for use in various pipeline stages of an execution pipeline. For example: the resources allocated to the processor core can be branch prediction resources, fetch 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.
The resource management unit refers to a unit provided in the electronic device for collectively managing resources of the electronic device. In the embodiment of the application, the resource management unit abandons an allocation strategy that fixed resources are allocated to each processor core and the resources of the processor cores are isolated from each other and cannot be shared, but performs unified management on the resources of the electronic equipment, and allocates the resources of the electronic equipment to the processor cores executing the pipeline based on the resource requirement of the pipeline. Therefore, the processor core with large load can obtain more resources, and the processor core with small load can obtain less resources, so that the distribution of the resources among the processor cores is more reasonable and balanced, the utilization rate of the resources is greatly improved, and the problems of resource distribution and asymmetric load of the processing cores are avoided.
Moreover, the resource management unit is used for uniformly managing the resources of the electronic equipment, and all idle resources can be centralized and used for being distributed to the processor cores of the execution pipelines. Therefore, the requirements of complex pipelines or high-strength pipelines with larger resource demand on resources are easier to meet, and the processing capacity and the computing performance of the electronic equipment can be further improved.
In addition, the resource management unit can uniformly manage the resources of the electronic equipment, and can further divide the allocable resources in the electronic equipment into resources in an awakening state and resources in a dormant state, and enable the resources in the dormant state to operate in a low-energy-consumption mode, so that the energy consumption of the whole plurality of electronic equipment is reduced.
The above advantages are particularly emphasized when the electronic device is a multi-core electronic device having at least two processor cores.
Based on the above inventive concept, an embodiment of the present application provides a resource state management method, where the method is applied to a resource management unit of the electronic device, and fig. 2 shows a main flow of implementing the resource state management method according to an embodiment of the present application, and as shown in fig. 2, the method includes:
operation S210, monitoring a resource calling condition of the electronic device in a first time interval;
wherein the first time interval is preset, for example, 1 minute, 5 minutes, 10 minutes, etc. Theoretically, too short a first time interval may cause the state of the resource to be frequently switched between the awake state and the sleep state, and increase the monitoring cost; the first time interval is too long, and the resource can enter the dormant state after being idle for a long time, so that the energy consumption can not be repeatedly saved.
Therefore, a better first time interval can be determined according to a plurality of experimental effects or model calculations.
The resource calling condition refers to whether the resource of the electronic equipment is called in a first time interval.
The resource management unit can monitor the resource calling condition of the electronic equipment in the first time interval in various ways.
For example, at the beginning time of the first time interval, a blank resource call table is created or the original resource call table is emptied; in the process of allocating resources to the processor cores of the execution pipeline, recording the allocated resources in the resource call table; and when the first time interval is over, checking the resource call table, wherein the resource recorded in the resource call table is called resource, and the resource not recorded is non-called resource.
Or, in the original resource management item, setting a flag bit for each resource item, and resetting the flag bit to a value representing 'no call' at the beginning of the first time interval; when the resource is called, the flag bit is set to a value representing 'called'; when the first time interval is over, the flag bit of each resource item is checked, so that whether the resource is called or not can be obtained.
In the implementation of the present application, each resource does not only refer to a single resource in the meaning, but also refers to the smallest resource unit available for allocation according to the resource allocation policy. These minimum resource units available for allocation may comprise a single resource or may comprise multiple resources.
For example, the resource management unit divides the branch prediction resources into one or more branch prediction sub-resource pools based on the resource allocation policy, each of the branch prediction sub-resource pools including resources of the same or different sizes. Each branch predictor resource pool is an allocable resource unit.
In operation S220, the state of the resource is controlled based on the resource calling condition, where the state of the resource includes a sleep state or a wake state.
Typically, the default state of a resource of an electronic device is an awake state. If the resource is called in the first time interval, keeping the resource in the wake-up state; and if the resource is not called, controlling the state of the resource to be switched from the awakening state to the sleeping state.
When the state of the resource is switched to the dormant state, the resource can be controlled to run in a low-energy-consumption mode, so that the energy consumption of the whole electronic equipment is further saved.
Some resources that lose some performance or functionality when operating in a low power consumption mode may affect the performance of a processor core if allocated to the processor core for an execution pipeline.
For this reason, in most embodiments of the present application, only the resources in the wake state are allocated to the processor core executing the pipeline; while resources in the sleep state are not used for the execution pipeline.
Therefore, the processing range of resource allocation can be further reduced, the calculation load of the resource management unit is reduced, and the management efficiency of the resources is improved.
After the state of the resource is switched to the dormant state, the resource in the dormant state can be awakened when the awakening condition is met, the state of the resource is controlled to be switched from the dormant state to the awakening state, and the performance core function is recovered.
In an embodiment of the present application, the wake-up condition includes a flow of waking up a resource in a sleep state, as shown in fig. 3, where the size of the resource in the wake-up state is smaller than that of the resource required by the pipeline;
operation S310, determining a size of a resource required by the pipeline and a size of a resource in an awake state;
the size of the resource required by the pipeline can be determined by estimating the size of the resource through the data amount processed by the pipeline, the operation type, the execution period and the like.
When the pipeline needs multiple resources, the size of each resource needed by the pipeline and the size of the resource in each resource for the allocated wake state need to be determined.
The resource size of each wake-up state can be determined by counting the resource size of each resource for which the allocated state is the wake-up state.
For example, the resource management unit creates a resource pool for each resource, respectively, for storing the resources available for the allocated wake state. The instruction-fetching resource pool is used for storing instruction-fetching resources in an awakening state which can be used for distribution; the decoding resource pool is used for storing decoding resources of the wake-up state which can be used for allocation; the operation resource pool is used for storing operation resources of the wake-up state which can be used for distribution; the storage resource pool is used for storing storage resources of the wake state which can be used for allocation and the like.
Assuming that the current assembly line needs the fetch resource, the decode resource, the operation resource and the storage resource, the size of the resource in the fetch resource pool, the size of the resource in the decode resource pool, the size of the resource in the operation resource and the size of the resource in the storage resource are respectively counted to determine the size of the resource in each resource, which can be allocated and is in the wake-up state.
Operation S320, determining whether the size of the resource needed by the pipeline is smaller than the size of the resource in the wake-up state, if not, continuing to operate S330, and if so, continuing to operate S340;
when the pipeline needs a plurality of resources, it needs to be determined that the size of each resource needed is smaller than the size of the resource of the awake state available for allocation in each resource.
Operation S330, acquiring resources in a sleep state, and controlling the state of the resources in the sleep state to be switched from the sleep state to an awake state;
optionally, resources in all dormant states may be acquired; dormant resources of a desired size may also be acquired.
In operation S340, according to the size of the resource needed by the pipeline, the corresponding wake-up resource is obtained, and the obtained wake-up resource is allocated to the processor core that executes the pipeline.
In the embodiment of the present application shown in fig. 3, the resources in the sleep state are awakened only when the resources in the awake state are not enough. In this way, the idle resources can be in the dormant state for as long as possible, thereby reducing the energy consumption of the electronic device to the greatest extent possible.
In another embodiment of the present application, the wake-up condition includes that a duration of a sleep state of the resource reaches a set duration threshold; accordingly, after the state of the control resource is switched from the awake state to the sleep state, the method further comprises: and starting a dormancy timer, wherein the dormancy timer is used for triggering the resource management unit to control the state of the resource to be switched from the dormant state to the awakening state after the set duration threshold.
The set time length threshold can be flexibly determined according to implementation requirements or implementation effects.
Through the set time length threshold, the judgment of the awakening condition can be simplified, and the resource size of the existing awakening state is not required to be known; moreover, through the set time length threshold, the resources can be in the core awakening state in the dormant state in turn, the use frequency of each resource is balanced, and the service life shortening caused by overload work due to the fact that individual resources are always in the awakening state is avoided.
In order to save the start of the dormancy timer, the resources that are not called in the first time interval may be used as a batch of resources, and the same batch of resources share one dormancy timer.
In another embodiment of the present application, the waking condition includes detecting a failed resource, where the failed resource is a resource that is used due to a failure of the resource, and as shown in fig. 4, the process of waking up the resource in the dormant state includes:
operation S410, acquiring a resource from the resources of the electronic device;
the acquired resource may be a resource that is already used or may be an allocatable wake-up state resource.
Operation S420, performing health detection on the resource;
operation S430, determining whether the resource is a fault resource, if yes, continuing to step S440, otherwise, returning to operation S410 to obtain a next resource;
operation S440, acquiring a resource in a dormant state;
operation S450, controlling the state of the resource to be switched from the sleep state to the wake state;
operation S460 replaces the failed resource with the awakened resource.
For example, a table or configuration entry referencing the failed resource is scanned and the awakened resource is used in place of the failed resource.
When a processor core calls a failing resource, it may cause the processor core to fail or cause the processor to relinquish the current resource to acquire the next available resource. This may result in a lack of resources and may result in serious errors such as a jam or crash.
In the embodiment of the application, the resources in the electronic device are regularly detected for health, so that the fault resources can be timely found, the resources in the dormant state are awakened, and the fault resources are replaced by the awakened resources, so that the performance of the processor core is ensured, and the probability of errors caused by the fault resources of the processor core is reduced.
Fig. 5 shows another embodiment of the present application, in which a main flow of a resource state management method is implemented by a dormant resource pool, and the method includes:
operation S510, acquiring allocable resources;
since resources in the dormant state are all placed in the dormant resource pool, the resources available for allocation are all resources in the awake state.
Operation S520, acquiring a calling condition of the resource in a first time interval;
operation S530, determining whether the resource is called, if so, continuing to operate S540, otherwise, returning to operation S510 to obtain the next allocable resource;
operation S540, controlling the state of the resource to be switched from the awake state to the sleep state;
in operation S550, the resource is added to the dormant resource pool.
The dormant resource pool is created in advance, and can be realized through a queue or a stack.
In another process or thread, the following is performed to wake up a resource in a sleep state:
operation S560, in response to the wake-up condition being satisfied, acquiring resources in a dormant state from the dormant resource pool;
operation S570, executing a wakeup operation, and controlling the state of the resource to be switched from the sleep state to the wakeup state;
in operation S580, resources in the dormant state are removed from the dormant resource pool.
In the embodiment of the application, the resources in the dormant state and the resources in the awakening state are separately managed through the dormant resource pool, so that the operation of traversing each resource to acquire the resource state can be greatly reduced, and the efficiency of resource management is greatly improved.
Further, an embodiment of the present application further provides a resource status management apparatus, which is applied to a resource management unit of an electronic device, where the resource management unit allocates resources of the electronic device to a processor core executing a pipeline based on resource requirements of the pipeline, as shown in fig. 6, the apparatus 60 includes: a resource calling condition monitoring module 601, configured to monitor a calling condition of a resource in a first time interval; the resource state control module 602 is configured to control a state of a resource based on a resource calling condition, where the state of the resource includes a sleep state or a wake state.
