[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0041] like Figure 1 As shown, this application provides an electronic device, including a first processing unit, a second processing unit, a resource scheduling unit, and a storage unit, wherein...
[0042] Storage unit, used to store target data;
[0043] The first processing unit is used to send a first data access request to the resource scheduling unit. The first data access request is used to obtain the target data of the storage unit.
[0044] The second processing unit is used to send a second data access request to the resource scheduling unit. The second data access request is used to obtain the target data of the storage unit.
[0045] The resource scheduling unit is used to receive access requests from the first processing unit and / or the second processing unit, obtain the target data of the storage unit based on the access request, and feed it back to the first processing unit and / or the second processing unit accordingly; if the access request is an access request from the first processing unit, the resource scheduling unit will transmit the obtained target data to the first processing unit.
[0046] For example, such as Figure 2 As shown, the electronic device can be a laptop, desktop computer, etc., and the specific type is not fixed. The electronic device in this embodiment includes a first processing unit, such as a GPU or other processing device; a second processing unit, such as a CPU, SOC, or other processing device; and a storage unit, such as a hard disk (NAND in the figure) or non-volatile storage media such as memory, and the specific type is not fixed. A resource scheduling unit (USA resource scheduler in the figure) can be firmware integrated on the motherboard. In practical applications, the storage unit is used to store target data, including documents, multimedia data, configuration parameters, etc. The first processing unit can send a first data access request to the resource scheduling unit to inform the resource scheduler of the target data it wishes to access in the storage unit. The second processing unit can send a second data access request to the resource scheduling unit to inform the resource scheduler of the target data it wishes to access in the storage unit. After receiving the first and second data access requests, the resource scheduling unit can respond to each access request, retrieve the target data from the storage unit, and feed the target data back to the first processing unit, the second processing unit, or both simultaneously. Specifically, the first processing unit, for example, when the first processing unit is a GPU, can directly interact with the resource scheduling unit, so that the resource scheduling unit can directly feed back the target data to the first processing unit without the need for other processing units, such as the second processing unit, thereby improving the data access efficiency of the first processing unit and reducing the data processing load of the second processing unit.
[0047] Based on the disclosure of the above embodiments, it can be understood that the beneficial effects of this embodiment include setting up a resource scheduling unit, which enables it to directly receive and respond to data access requests sent by the first processing unit and the second processing unit, and directly obtain the target stored data from the storage unit and feed it back to the corresponding first processing unit and / or second processing unit. In particular, when the first processing unit needs to access the target data, the second processing unit does not need to participate, and it feeds back the target data to the first processing unit through a relay, which greatly reduces the processing load of the second processing unit and reduces the hardware path of data access.
[0048] Furthermore, continue to combine Figure 2 As shown, the electronic device in this embodiment includes a first bus (connected to the GPU), such as a PCIe bus, a PEG bus, or other types of buses used for data transmission. The first bus is connected to a first processing unit and a resource scheduling unit. In application, the first bus can be directly or indirectly connected to the first processing unit and the resource scheduling unit. For example, it can be connected to the first processing unit and the resource scheduling unit through other devices, or it can be directly connected. The first processing unit sends a first access request to the resource scheduling unit via the first bus, and simultaneously receives the target data via the first bus.
[0049] Furthermore, continue to combine Figure 2 As shown, the electronic device also includes a second bus, which can also be a PCIe bus (connected to the SOC) or other types of buses used for data transmission. The second bus can also be directly or indirectly connected to the second processing unit and the resource scheduler. Through the second bus, the second processing unit can send a second access request to the resource scheduler and receive feedback target data.
[0050] Furthermore, combined Figure 3 As shown, the electronic device in this embodiment also includes a controller, which is connected to or can be disposed on the first bus. The controller is also connected to a second processing unit and a resource scheduling unit. The second processing unit can send access requests to the resource scheduling unit and receive feedback data based on the controller. That is, the controller is connected to the first processing unit via the first bus, and simultaneously connected to the second processing unit and the resource scheduler. Thus, not only can the first processing unit interact with the resource scheduler through the controller, but the second processing unit can also interact with the resource scheduler through the controller.
[0051] Specifically, the controller in this embodiment has multiple interfaces, which are respectively connected to the first processing unit and the second processing unit. For example, they are connected to the first processing unit via a first bus, and to the second processing unit and the resource scheduler via connecting lines. The controller determines whether the sender of the access request is the first processing unit or the second processing unit based on different interfaces. For example, based on the first interface, it determines that the received access request is the first access request, sent by the first processing unit, and based on the second interface, it determines that the received access request is the second access request, sent by the second processing unit. Alternatively, the access request may carry identification information representing the sender's identity, and the controller can determine whether the sender is the first or the second processing unit based on the identification information in the access request. Of course, other methods can also be used to determine the identity of the sender of the access request, and the specific methods are not limited to these.
[0052] In this embodiment, the first processing unit notifies the second processing unit of the target data it wants to access in the storage unit based on the controller, so that the second processing unit controls the controller to separate a portion of the channel for communication with the resource scheduling unit.
[0053] The first processing unit receives feedback information from the second processing unit and responds to the feedback by calling the resource scheduling unit through the controller. The feedback information is used to indicate that the first processing unit can interact directly with the resource scheduling unit through the controller to call the resource scheduling unit.
[0054] For example, when the first processing unit wants to access target data in the storage unit, it can first send a first data access request to the controller. The controller then forwards the first data access request to the second processing unit. The second processing unit analyzes and determines whether the first processing unit meets the access requirements, such as identity authentication of the first processing unit and security authentication of the target data. Once it is determined that the first processing unit can access the target stored data in the storage unit, the second processing unit can control the controller to allocate a portion of the channel for communication with the resource scheduler. At the same time, the controller sends the first data access request to the resource scheduling unit for processing, so that the resource scheduling unit responds to the first data access request, obtains the target data that the first processing unit wants to access from the storage unit, and then feeds it back to the first processing unit through the controller, thus completing the first processing unit's access to the target data.
[0055] Alternatively, when the first processing unit wants to access target data in the storage unit, it can first send an access notification to the controller. The controller then forwards the access notification to the second processing unit. The second processing unit analyzes and determines whether the first processing unit meets the access requirements, such as passing the first processing unit's authentication and the target data's security authentication. If it is determined that the first processing unit can access the target stored data in the storage unit, the second processing unit can control the controller to allocate a portion of the channel for communication with the resource scheduler. Simultaneously, the second processing unit will send feedback information to the controller, which will then relay this information to the first processing unit, informing it that it is permitted to call the resource scheduler through the controller. At this point, the first processing unit can send a first data access request to the controller, which forwards the request to the resource scheduler for processing. Upon receiving the first data access request, the resource scheduler will respond by retrieving the target data that the first processing unit wants to access from the storage unit, and then relaying this information back to the first processing unit through the controller, thus completing the first processing unit's access to the target data.
[0056] Since the controller in this embodiment is connected to both the first processor and the second processor, and as described in the previous embodiment, the controller can be used to perform data transmission between the first processing unit and the second processing unit. For example, the first processing unit can transmit a first data access request to the second processing unit through the controller, the second processing unit can transmit target data to the first processing unit through the controller, or the first processing unit can directly transmit interactive data with the second processing unit through the controller, such as the CPU and GPU transmitting interactive data to each other. This data is non-target data and does not need to be extracted from the storage unit or called from the resource scheduling unit. In this embodiment, the controller acts as a converter. When the resource scheduling unit is not called, all its channels are used to connect the first processing unit and the second processing unit. When the resource scheduling unit needs to be called, the controller needs to transfer some channels to the resource scheduling unit under the control of the second processing unit, thereby enabling the first processing unit and the second processing unit to interact with the resource scheduling unit through the controller, transmitting access requests and feedback target data.
[0057] In practical applications, the controller, second bus, second processing unit, and resource scheduling unit can be mounted on the same substrate. One interface of the controller can be connected to the second bus, and the first processing unit can be externally mounted on the substrate. The first processing unit can be connected to another interface of the controller via the first bus. Of course, the controller, second bus, first processing unit, second processing unit, first bus, and resource scheduling unit can all be integrated on the same substrate. Alternatively, the first and second processing units can be set up independently, while the controller and resource scheduling unit are integrated on the same substrate, with the controller connected to the first and second processing units respectively via the first and second buses. The specific structure is not unique and can be determined according to the actual configuration of the electronic device.
[0058] Specifically, continue to combine Figure 3 As shown, the architecture in this embodiment separates the CPU from the PCIe controller in the PCH (integrated southbridge) used for accessing NVMe (non-volatile memory medium) data (i.e., target data in the memory cell). This allows the data interaction between the CPU and GPU to remain largely the same as before. The difference is that the GPU can directly access the NVMe SSD (memory cell) through the existing PEG bus, eliminating the need for a path from the CPU to the PCH and then to the NVMe SSD. This saves hardware link time, improves data access efficiency, and reduces CPU load. Based on this embodiment, electronic devices, especially when watching videos or playing video games, can quickly eliminate progress bars, resulting in smoother visuals and faster loading of large amounts of images and videos. Specifically, this can be combined with… Figure 4 As shown, the effect is remarkable.
[0059] like Figure 5 As shown, another embodiment of this application also provides a control method applied to the resource scheduling unit of an electronic device as described in any of the embodiments above, the method comprising:
[0060] S100: Obtain a first data access request from the first processing unit or a second data access request from the second processing unit;
[0061] S200: In response to the first data access request or the second data access request, obtain the target data of the storage unit and feed it back to the first processing unit and / or the second processing unit accordingly;
[0062] If the access request is the first access request, the resource scheduling unit will transmit the acquired target data to the first processing unit.
[0063] For example, when the resource scheduling unit receives a first data access request from the first processing unit, it responds to the request, determines that the first processing unit wants to access the target data, interacts with the storage unit, obtains the target data from the storage unit, and can either directly return it to the first processing unit or return it to the second processing unit, which then forwards it to the first processing unit. If the resource scheduling unit cannot interact with the first processing unit and the link between them is broken, the second processing unit can forward the target data. Alternatively, if the target data requires access permission authentication, the resource scheduling unit can send the target data to the second processing unit for authentication, and then determine whether to forward it to the first processing unit based on the authentication result. Of course, the resource scheduling unit itself can also have authentication functionality to authenticate access requests and the access permissions of the target data. Furthermore, when the resource scheduling unit receives a second data access request from the second processing unit, it responds to the request, determines that the second processing unit wants to access the target data, interacts with the storage unit, obtains the target data from the storage unit, and directly returns it to the second processing unit. Alternatively, when the resource scheduling unit receives both the first data access request and the second data access request simultaneously, meaning both the first processing unit and the second processing unit need to access the target data, the resource scheduling unit can copy the target data and simultaneously send it back to both the first and second processing units. Alternatively, it can send the access address of the target data back to both the first and second processing units, allowing them to directly access the target data based on the access address. Or, the resource scheduling unit can interact with both the first and second processing units to determine their access urgency, determine the feedback priority of the target data based on the urgency, and then send the target data back in sequence according to the priority.
[0064] Based on the disclosure of the above embodiments, it can be understood that the beneficial effects of this embodiment include that the resource scheduling unit can directly receive and respond to the data access requests sent by the first processing unit and the second processing unit, and directly obtain the target stored data from the storage unit and feed it back to the corresponding first processing unit and / or second processing unit. In particular, when the first processing unit needs to access the target data, the second processing unit does not need to participate, and the second processing unit will relay the target data back to the first processing unit, which greatly reduces the processing load of the second processing unit and reduces the hardware path for data access.
[0065] In this embodiment, the first processing unit can be a GPU, dGPU, etc., and the second processing unit can be a CPU, etc., the specifics are not fixed.
[0066] Further, obtaining a first data access request from the first processing unit or a second data access request from the second processing unit includes:
[0067] S101: Obtain the first data access request or the second data access request from the first processing unit or the second processing unit through the first bus or the second bus.
[0068] That is, in this embodiment, the first processing unit is connected to the first bus, the second processing unit is connected to the second bus, and the resource scheduling unit is connected to the first bus and the second bus respectively. The resource scheduling unit obtains the first data access request and the second data access request through the first bus and the second bus respectively. In other words, the resource scheduler can determine the identity of the access requester based on whether the received data access request is transmitted by the first bus or the second bus, and then realize the matching response.
