[0002] With the increasing complexity of chip design, more and more modules are integrated in the chip, which may initiate access operations on the public resources inside the chip, such as access to shared memory, which causes the problem of multi-device resource competition. For multi-core processors on chip, as the number of processor cores increases, multi-threading competes more fiercely for limited shared resources in the system, and thus has a more obvious impact on system performance.

[0003] In the prior art, the method for allocating and scheduling limited shared resources among multi-threads generally adopts the way of master core to execute scheduling algorithm to allocate shared resources among multi-threads. This way not only consumes on-chip core computing resources, but also is difficult to guarantee real-time performance in the resource scheduling process, thus causing problems such as low work efficiency and system storage fragmentation, which greatly affects system performance and storage efficiency.

In a typical scenario, the value of the resource is statically mapped to different resource areas of the system by defining or assigning the value of the resource, and the number of resource agents corresponding to different resource applicants is limited to achieve flexibility and efficiency of system resource use. The resource agent in the present application is an intermediate agent responsible for managing part or all of the key information of the resource, and the resource applicant and consumer can apply for resource information from the resource agent or return the resource information to the resource agent. By configuring the number of resources managed by the resource agent, the use amount of resources by different resource applicants and consumers can be effectively controlled and balanced. The resource group flip in the present application is a flip behavior of the recycling resource group, and the recycling resource group is a group formed by recycling resource keys. The flip is to allocate multiple keys in the recycling resource group to multiple recycling channels corresponding to the number of keys according to the order of use of the recycling channel to recycle. According to the resource group flip, the utilization rate of the recycling channel can be improved, and more time can be obtained for each recycling channel to process recycling events.

[0009] In some embodiments, the step of judging whether the pre-allocated resource number of the resource agent corresponding to a resource applicant meets the required resource number of the resource applicant, and feeding back the corresponding application result to the resource applicant according to the judgment result comprises: in response to the pre-allocated resource number of the resource agent corresponding to a resource applicant meeting the required resource number of the resource applicant, applying the required resource number to the resource pool through the resource agent corresponding to the resource applicant, and returning the value and a valid flag of the applied required resource number to the resource applicant; and in response to the resource applicant judging that the valid flag is valid, the resource applicant initiates access to system resources according to the value of the applied required resource number.

[0010] In some embodiments, the judging whether the pre-allocated resource number of the resource agent corresponding to the resource applicant meets the required resource number of the resource applicant comprises: in response to the pre-allocated resource number of the resource agent corresponding to the resource applicant not meeting the required resource number of the resource applicant, the resource agent corresponding to the resource applicant does not apply for the required resource number from the resource pool, and returns an invalid flag to the resource applicant.

[0011] In some embodiments, the setting the resource recycling channel to receive and allocate the to-be-recycled resource to the corresponding resource agent for recycling through resource group flipping comprises: setting a flipping register in the resource recycling channel, and in response to the flipping register being valid, the resource recycling channel writes the received to-be-recycled resource into a first-in-first-out queue after reversing, so as to reduce the receiving pressure of the first-in-first-out queue of the resource recycling channel.

[0028] One or more embodiments of the present application will be described below with reference to the accompanying drawings.

[0029] Based on the above purpose, in a first aspect of the embodiments of the present application, an embodiment of a method for system resource configuration is provided. Figure 1 A schematic diagram of an embodiment of a method for system resource configuration provided by the present application is shown. As shown in Figure 1 The method for system resource configuration of the embodiments of the present application includes the following steps:

[0030] S101, initializing a resource pool and allocating resource agents to the resources of the resource pool to obtain pre-allocated resources corresponding to each resource agent;

[0031] S102, judging whether the number of pre-allocated resources of the resource agent corresponding to the resource applicant meets the required resource number of the resource applicant, and feeding back the corresponding application result to the resource applicant according to the judgment result;

[0032] S103, setting a resource recycling channel to receive and allocate the to-be-recycled resources to the corresponding resource agents for recycling by means of resource group flipping.

[0033] According to several embodiments of the present invention, the method provided in this application further includes: setting up agent request arbitration logic based on different resource agents' application requests or recycling requests for resources, arbitrating the application requests and / or recycling requests through the agent request arbitration logic, and sending the arbitration result to the resource pool, so as to complete the different resource agents' application requests or recycling requests for resources.

[0034] According to several embodiments of the present invention, initializing a resource pool and allocating resource agents to the resources of the resource pool to obtain pre-allocated resources corresponding to each resource agent includes: setting the resources of the resource pool through a circular buffer data structure and configuring the registers associated with the resource pool to set the initialization of the resource pool; allocating resource agents to the resources of the resource pool, setting the maximum number of allocatable resources for each resource agent according to the initialization of the resource pool, and obtaining the pre-allocated resources corresponding to each resource agent.

[0035] According to several embodiments of the present invention, setting the resources of a resource pool through a circular buffer data structure and configuring the registers associated with the resource pool to set the initialization of the resource pool includes: setting the effective range of the resources of the resource pool by configuring the registers associated with the resource pool; and configuring the registers associated with the resource pool to select an automatic initialization mode or a configuration initialization mode for the resource pool.

[0036] According to several embodiments of the present invention, determining whether the pre-allocated resource number of the resource agent corresponding to the resource applicant meets the resource applicant's required resource number, and feeding back the corresponding application result to the resource applicant based on the determination result includes: in response to the resource agent corresponding to the resource applicant meeting the resource applicant's required resource number, applying for the required resource number from the resource pool through the resource agent corresponding to the resource applicant, and returning the value of the requested required resource number and a validity flag to the resource applicant; in response to the resource applicant determining that the validity flag is valid, the resource applicant initiates access to system resources based on the value of the requested required resource number.

[0037] According to several embodiments of the present invention, determining whether the number of pre-allocated resources of the resource agent corresponding to the resource applicant meets the number of resources required by the resource applicant, and feeding back the corresponding application result to the resource applicant based on the determination result includes: in response to the fact that the number of pre-allocated resources of the resource agent corresponding to the resource applicant does not meet the number of resources required by the resource applicant, the resource agent corresponding to the resource applicant does not apply for the required number of resources from the resource pool, and returns an invalid flag to the resource applicant.

[0038] According to several embodiments of the present invention, setting up a resource recycling channel to receive and allocate resources to be recycled to the corresponding resource agent for recycling by means of resource group flipping includes: setting a flip register in the resource recycling channel; in response to the flip register being valid, the resource recycling channel reverses the received resources to be recycled and writes them into a first-in-first-out queue, so as to reduce the receiving pressure of the first-in-first-out queue of the resource recycling channel.

[0039] The system resource configuration method proposed in this invention specifies the initial HP and TP positions and the resource pool initialization content through register configuration during resource pool initialization; reduces disordered competition for resources by resource applicants through key resource pre-allocation by resource proxy; and reduces the receiving pressure of the recycling channel FIFO by key group flipping operation in the resource recycling channel.

[0040] The following provides specific steps of another embodiment of a system resource allocation method based on the present invention.

[0041] Figure 2 A schematic diagram of the resource pool structure provided by the present invention is shown, as follows: Figure 2 As shown, a resource pool is constructed using a Ring Buffer. The resource pool stores the key information of resources. Only when a resource requester obtains the key information can they operate on the resource. A Ring Buffer is a data structure used to represent a fixed-size, contiguous circular buffer, containing storage space, a head pointer (HP), a tail pointer (TP), and their change logic. During resource pool initialization, HP = TP = InitialAddr, where InitialAddr is the initialization register configuration value. When a key (resource) is read from storage space and dispatched, HP = HP + 1. When a key is written to storage space and reclaimed, TP = TP + 1. When HP or TP reaches the maximum storage space value, HP = 0 or TP = 0 when another key is dispatched or reclaimed. An invalid key indicates a key that has been dispatched, and the resource user is using the resource corresponding to that key and has not yet returned it to the resource pool; a valid key indicates a key that has not yet been dispatched, and the resource corresponding to that key is in a pending state.

[0042] By establishing such Figure 3The resource pool control unit shown determines the valid scope of resource information within the resource pool and the initialization method of the resource pool. The valid scope of resource information within the resource pool is determined by the MaxKeyNum register, which includes the usage range of storage space and the maximum values ​​of HP and TP, where HP ≦ MaxKeyNum and TP ≦ MaxKeyNum. The initialization method of the resource pool is determined by the InitForm register. In this embodiment, two initialization modes are supported: automatic initialization mode and configuration initialization mode. In automatic initialization mode, after system startup, the memory address (which can be converted to a resource address through static mapping, generally referring to "adding to the resource base address") is dispatched as the key value of HP. When HP exceeds the memory boundary and rolls back, the value is read from the memory again as the key value for dispatch. In configuration initialization mode, after system startup, the value inside the memory needs to be configured before it can be dispatched as the key value.

[0043] By establishing such Figure 4The resource agent shown limits the number of system resources that resource applicants can access. The maximum number of keys that the current resource agent can allocate is determined by the AgentMaxKeyNum register, whose value is configured during system initialization. The resource agent obtains key information from the resource recycling channel and writes it to the resource pool. When there are enough resources, the resource agent requests keys from the resource pool and prepares them for resource applicants; when there are insufficient resources, the resource agent returns invalid key information after a resource applicant requests key information. When the agent dispatches a key, the register value is decremented by 1; when the agent recycles a key, the register value is incremented by 1. An error is reported when the register value is greater than the initial configuration value or less than 0. When the AgentMaxKeyNum register value is sufficient and the local cache pointer is less than the "key pre-read write boundary," the resource agent pre-requests one or more key values ​​from the resource pool and places them in the local cache. The "key pre-read write boundary" can be a constant value or a register configuration value. When a resource applicant requests a key through a register read operation, the key value and a valid flag are returned directly, indicating that the returned key value is valid. When the AgentMaxKeyNum register value is insufficient, the resource agent cannot or will no longer request a key value from the resource pool in advance. When a resource requester requests a key through a register read operation, it can directly return the key value and an invalid flag, indicating that the resource request failed and the returned key value is invalid. When returning the key value, the current agent's ID information, i.e., AgentID, needs to be included. When the resource agent receives a request to reclaim a key, it first checks whether the local cache pointer is less than the "key reclamation write boundary." If it is less, it directly writes the key value to the local cache; otherwise, it requests to write the key value back to the resource pool. The "key reclamation write boundary" can be a constant value or a register configuration value.

[0044] Arbitration logic is configured to receive request and eviction requests for keys from different resource proxies. Request requests can be arbitrated using Round Rubin (RR) and / or Weight Rubin (WR); eviction requests can be arbitrated using RR.

[0045] A resource recycling channel is set up to receive key recycling requests from resource recyclers and key recycling requests from resource applicants. Within the resource recycling channel, resources to be recycled are received and allocated to corresponding resource agents for recycling through resource group flipping. In this embodiment, resource group flipping is implemented by setting a key group flipping register, i.e., a RevKeyGroup register, within the resource recycling channel. Figure 5 The diagram illustrates the forward and reverse write-back during resource recycling. When the recycler writes multiple keys into the resource recycling channel in groups and the RevKeyGroup register is valid, the channel FIFO will reverse the key group and write it back to the channel FIFO after each key group is received. This reduces the receiving pressure on the recycling channel FIFO.

[0046] The internal resource pool, the Ring Buffer, can be stored using on-chip storage resources such as SRAM and registers, with unlimited storage width. Therefore, a single allocation or reclamation can involve one or more key resources. One or more resource brokers can be used, and each broker can dispatch or reclaim one or more resources per transaction. Broker request arbitration logic can be implemented through custom logic or via a bus. The resources written to the reclamation channel by the resource reclaimer can be a group of keys or a single key.

[0047] This invention proposes a system resource configuration method that balances resource pool initialization, resource pool control, resource proxying, and resource reclamation operations, thereby balancing system resource request and reclamation. In the initial state of the resource pool, initial HP and TP values ​​are configured via registers. When the resource pool adopts automatic initialization mode, balanced use of system resources can be achieved. During resource pool initialization, two design modes are proposed: automatic initialization and configuration initialization. When system resource keys are consecutive, automatic initialization effectively reduces the initialization time and hardware logic overhead. When the system expects flexible distribution of resource keys, configuration initialization provides support for this operation. Concurrent access to the resource pool is achieved through multiple resource proxies. This method not only increases the resource pool access bandwidth but also limits the number of system resources accessed by resource requesters through proxying, ensuring that system resources are used under the expected register configuration. The resource reclamation channel reduces the receiving pressure of the FIFO through key group flipping.

[0048] The following is a schematic diagram illustrating the interactive process of a system resource configuration method based on the present invention. For example... Figure 6 As shown, the steps for interaction using the system resource configuration method proposed in this invention include:

[0049] S1: Key value pre-reading. After the resource pool completes the initial state operation, the resource agent that is allocated the resource will pre-read the key value from the resource pool for use in subsequent resource requests.

[0050] S2: Resource Request. When a resource requester has a need to use resources, they submit a request to the corresponding resource agent.

[0051] S3: Returns the key value. The resource agent returns the key value and the corresponding valid flag to the resource requester.

[0052] S4: Key value matching. The resource applicant confirms the validity by marking it as valid. The applicant then uses this key value to initiate access to the system resource set. When the system resource is storage space, the key value is generally the memory address.

[0053] S5: Resource usage, where the resource applicant uses the system resources they have applied for to complete the current task.

[0054] S6: Key value recycling request. After completing the current task, the resource applicant sends the key value back to the resource recycling channel to release the right to operate on the resource.

[0055] S7: Key value write-back. The recycling channel returns the key value to the corresponding agent based on the agent ID in the recycling information.

[0056] S8: Key value recycling, the agent writes the key value back to the resource pool.

[0057] By interacting with the system resource configuration method proposed in this invention, resource pre-allocation can be achieved through resource proxy during resource use, reducing disorderly competition for resources among resource applicants; during resource reclamation, key group flipping operation within the resource reclamation channel is used to reduce the receiving pressure of the FIFO in the reclamation channel.

[0058] A second aspect of the present invention provides an apparatus for system resource allocation.

Claims

1. A method for system resource allocation, characterized in that, include: The resource pool is initialized and resource agents are allocated to the resources in the resource pool to obtain the pre-allocated resources corresponding to each resource agent; Determine whether the number of pre-allocated resources for the resource agent corresponding to the resource applicant meets the resource applicant's required resource quantity, and provide feedback on the corresponding application result to the resource applicant based on the determination result; The resource recycling channel is configured to receive and allocate resources to corresponding resource agents for recycling by means of resource group flipping. This includes setting a flip register in the resource recycling channel. In response to the flip register being valid, the resource recycling channel reverses the received resources to be recycled and writes them into a first-in-first-out queue to reduce the receiving pressure on the first-in-first-out queue of the resource recycling channel.

2. The method according to claim 1, characterized in that, Also includes: Based on the different resource agents' requests for or requests to reclaim resources, an arbitration logic for agent requests is set up. The application requests and / or reclaim requests are arbitrated through the agent request arbitration logic, and the arbitration result is sent to the resource pool to complete the different resource agents' requests for or requests to reclaim resources.

3. The method according to claim 1, characterized in that, The process of initializing the resource pool and allocating resource proxies to the resources in the resource pool, resulting in pre-allocated resources for each resource proxy, includes: The resources of the resource pool are set using a circular buffer data structure, and the initialization of the resource pool is set by configuring the registers associated with the resource pool. Resource agents are assigned to the resource pool. Based on the initial settings of the resource pool, the maximum number of allocatable resources for each resource agent is determined, and the pre-allocated resources corresponding to each resource agent are obtained.

4. The method according to claim 3, characterized in that, The process of setting the resources of the resource pool through a circular buffer data structure and configuring the registers associated with the resource pool to initialize the resource pool includes: The effective range of resources in the resource pool is set by configuring the registers associated with the resource pool; By configuring the registers associated with the resource pool, the system can select between an automatic initialization mode and a configuration initialization mode for the resource pool.

5. The method according to claim 1, characterized in that, The process of determining whether the pre-allocated resource quantity of the resource agent corresponding to the resource applicant meets the resource applicant's required resource quantity, and feeding back the corresponding application result to the resource applicant based on the determination result, includes: In response to the resource requester's corresponding resource agent having a pre-allocated resource quantity that meets the resource requester's required resource quantity, the resource requester's corresponding resource agent requests the required resource quantity from the resource pool and returns the requested required resource quantity value and validity flag to the resource requester. In response to the resource requester determining that the validity flag is valid, the resource requester initiates access to system resources based on the requested required resource quantity value.

6. The method according to claim 1, characterized in that, The process of determining whether the pre-allocated resource quantity of the resource agent corresponding to the resource applicant meets the resource applicant's required resource quantity, and feeding back the corresponding application result to the resource applicant based on the determination result, includes: If the number of pre-allocated resources of the resource agent corresponding to the resource applicant does not meet the number of resources required by the resource applicant, the resource agent corresponding to the resource applicant will not apply for the required number of resources from the resource pool and will return an invalid flag to the resource applicant.

7. A device for system resource allocation, characterized in that, include: The first module configures the initialization of the resource pool and the allocation of resource agents to the resources of the resource pool, thereby obtaining the pre-allocated resources corresponding to each resource agent; The second module is configured to determine whether the number of pre-allocated resources of the resource agent corresponding to the resource applicant meets the number of resources required by the resource applicant, and to provide the corresponding application result to the resource applicant based on the determination result. The third module, configuration, is used to set up the resource recycling channel to receive and allocate the resources to be recycled to the corresponding resource agent for recycling through resource group flipping. The third module is also used to: set a flip register in the resource recycling channel; in response to the flip register being valid, the resource recycling channel reverses the received resources to be recycled and writes them into the first-in-first-out queue, so as to reduce the receiving pressure of the first-in-first-out queue of the resource recycling channel.

8. A computer device, characterized in that, include: At least one processor; as well as A memory storing computer instructions executable on the processor, which, when executed by the processor, implement the steps of the method according to any one of claims 1-6.

9. A computer-readable storage medium storing a computer program, characterized in that, When the computer program is executed by a processor, it implements the steps of the method according to any one of claims 1-6.
