All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
With the complexity of artificial intelligence, more and more scene processing needs to involve processing of multiple tasks, and when performing multiple tasks, a processor (such as an artificial intelligence network processor (Neural network Processing Unit, NPU)) needs to be frequently switched among the multiple tasks, and in a related manner, a control module (such as a micro control unit (Microcontroller Unit, MCU)) is generally used to interactively control the processor, so that the processor can normally process the multiple tasks.
The inventor finds that in the related research, in the process of interaction between the control module and the processor, the problem that the working stability of the control module needs to be improved exists.
Therefore, the inventor proposes a method, an apparatus and an electronic device for executing multiple tasks in the present application, where after the first control module receives configuration information of multiple tasks sent by the second control module, the first control module sends configuration information of one task to a first register of the processor, so that the processor executes a corresponding task based on the configuration information in the first register. Before the processor completes the task corresponding to the configuration information in the first register, the first control module sends the configuration information of one task in the remaining tasks to the second register of the processor, and the first control module responds to the task execution completion notification sent by the processor and sends the configuration information of one task in the remaining tasks to the target register in the processor until the tasks are executed by the processor, wherein the processor executes the corresponding task based on the configuration information in one of the registers and then directly executes the corresponding task based on the configuration information in the other register.
By the method, in the process of controlling the processor to execute the tasks, the second control module can be responsible for acquiring the configuration information of the tasks to be executed, and the first control module is responsible for interacting with the configuration information of the tasks to be executed by the processor, so that the first control module and the second control module can work cooperatively, the workload of a single control module is reduced, the efficiency of the processor for processing a plurality of tasks is improved, and the first control module and the second control module can work more stably under the condition of reduced workload.
Referring to fig. 1, the method for performing multiple tasks provided in the present application is applied to an electronic device, where the electronic device includes a first control module, a second control module, and a processor, and two registers are disposed in the processor, and the method includes:
s110: the first control module receives configuration information of a plurality of tasks sent by the second control module.
In this embodiment of the present application, the configuration information refers to information required in the task execution process, and may include configuration information of a register in a processor, a source address and a destination address of task data, and the like. The configuration information of the registers in the processor may be an identifier of a register that is needed in the task execution process. The task Data refers to Data that needs to be processed by the processor, the source address of the task Data refers to a storage address of the task Data, the destination address of the task Data is a storage address of Data processed by the processor, and the source address and the destination address of the task Data may be represented by address identifiers, for example, the source address and the destination address may be an address identifier of a Static Random-Access Memory (SRAM) storage area inside the processor, an address identifier of a Double Data Rate (DDR) storage area in the electronic device, and the like.
Furthermore, in the embodiment of the present application, the first control module may be a hardware configuration unit (Hardware programmer, HW programmer); the second control module can be MCU, etc.; the processor refers to a chip having data computing and image processing functions, for example: NPU, DSP (Digital Signal Processing ), etc.
As a way, the second control module may send configuration information of a plurality of tasks to the first control module at a time, and after the second control module receives the configuration information of the plurality of tasks, the configuration information of the plurality of tasks may be stored in a task summary table. For example, after the first control module receives the register configuration information corresponding to the plurality of tasks, the source address and the destination address of the task data, the first control module may store the configuration information in table 1 according to the correspondence between the tasks and the configuration information.
TABLE 1
S120: the first control module sends configuration information of a task to a first register of the processor, so that the processor can execute the corresponding task based on the configuration information in the first register, and the first register is any one of two registers included in the processor.
In one manner, the first control module may send configuration information of a task to the first register of the processor in response to the start instruction sent by the second control module, so that the processor may execute the corresponding task based on the configuration information in the first register.
Optionally, the processor further includes a direct memory access (Direct Memory Access, DMA) unit and a computing unit, where after the first control module sends configuration information of a task to a first register of the processor, the DMA may acquire register configuration information of a current task, a source address and a destination address of task data from the first register, acquire task data according to the acquired task data source address, and input the task data into a register corresponding to the current task (i.e., the first register) according to the acquired register configuration information; after the DMA inputs all task data into the register corresponding to the current task, the computing unit in the processor may perform related computation on the task data and send the computation result to the DMA, so that the DMA may send the computation result to the target address of the current task, and thus the processor may execute the corresponding task based on the configuration information in the first register.
For example, as shown in FIG. 2, the processor may be an NPU, with the source address and destination address of the current task data being located in separate storage areas in memory (e.g., DDR). After the second control module sends a starting instruction to the first control module, the first control module can respond to the starting instruction to send configuration information corresponding to the task one in the table 1 to the first register, and after the DMA obtains the configuration information of the task one from the first register, the DMA can load the characteristic image data and the weight data corresponding to the task one into the register corresponding to the task one in batches from the source address of the DDR; after loading is finished, the DMA may send a data loading completion signal to trigger a tensor operation unit and a vector operation unit in the NPU calculation unit to perform data calculation, where the tensor operation unit may perform convolution operation, and the vector operation unit may perform operations such as pooling operator, activating operator, scaling operator, and the like. After the data calculation is completed, the DMA may send the calculation result to the target address of the DDR.
S130: before the processor completes the task corresponding to the configuration information in the first register, the first control module sends the configuration information of one task in the remaining tasks to a second register of the processor, wherein the second register is a register in which the configuration information is not written in the registers included in the processor.
When the processor starts to process the task corresponding to the configuration information in the first register, the first control module may send the configuration information of one task of the remaining tasks to the second register of the processor. For example, as shown in fig. 3, the first control module may send the configuration information of the first task to the first register, and then send the configuration information of the second task to the second register at time T0.
Alternatively, the first control module may send the configuration information of one of the remaining tasks to the second register of the processor while sending the configuration information of the one task to the first register of the processor. For example, as shown in fig. 4, the first control module may send the configuration information of the task one and the task two to the first register and the second register before the time T0.
S140: the first control module responds to the task execution completion notification sent by the processor, and sends configuration information of one task of the remaining tasks to a target register in the processor, wherein the target register is a register for storing task configuration information corresponding to the task execution completion notification until the tasks are executed by the processor, and the processor executes the corresponding task directly based on the configuration information in one register after executing the corresponding task based on the configuration information in the other register.
The second control module can query the working state of the processor in real time, and when the second control module can query the computing unit in the processor to complete task data calculation, the second control module can take a register storing configuration information corresponding to the task completed by the current computing unit as a target register and send the information of the target register to the first control module, so that the first control module can send the configuration information of one task in the rest tasks to the target register in the processor. Illustratively, the second control module may be an MCU, the processor may be an NPU, and the first control module may be a HW programmer. When the MCU queries that the computing unit in the NPU completes task-one corresponding task data computation, the MCU may obtain table 1 obtained in step S110 from the HW programmer, and may determine a register storing task-one configuration information according to table 1, and use the register as a target register. The MCU then sends the information of the target register to the HW programmer, so that the HW programmer can send the configuration information of one task in the remaining tasks to the target register in the processor.
Alternatively, the target register corresponding to each task may be preconfigured by the second control module, where the second control module uses the configured target register as the register configuration information in the configuration information of each task. The second control module may alternatively configure the target registers, and for example, when the target register of the task one is the first register, the target register of the task two is the second register, and the target register of the task three is the first register. When the calculation unit in the processor completes the calculation of the task data, the processor can send a task execution completion notification to the first control module; the first control module responds to a task execution completion notice sent by the processor, and sends the configuration information of one task in the remaining tasks to a target register in the processor, namely a register corresponding to the configuration information of the register, based on the configuration information of the register in the configuration information of the one task in the remaining tasks. Illustratively, the processor may be an NPU and the first control module may be a HW programmer. When the HW programmer receives the task execution completion notification corresponding to the task one sent by the NPU, the target register of one task in the remaining tasks may be determined from table 1 obtained in step S110, and the configuration information of the task may be sent to the target register in the NPU.
In the multitasking execution method provided in this embodiment, after the first control module receives the configuration information of a plurality of tasks sent by the second control module, the first control module sends the configuration information of one task to the first register of the processor, so that the processor executes the corresponding task based on the configuration information in the first register. Before the processor completes the task corresponding to the configuration information in the first register, the first control module sends the configuration information of one task in the remaining tasks to the second register of the processor, and the first control module responds to the task execution completion notification sent by the processor and sends the configuration information of one task in the remaining tasks to the target register in the processor until the tasks are executed by the processor, wherein the processor executes the corresponding task based on the configuration information in one of the registers and then directly executes the corresponding task based on the configuration information in the other register. By the method, in the process of controlling the processor to execute the tasks, the second control module can be responsible for acquiring the configuration information of the tasks to be executed, and the first control module is responsible for interacting with the configuration information of the tasks to be executed by the processor, so that the first control module and the second control module can work cooperatively, the workload of a single control module is reduced, the efficiency of the processor for processing a plurality of tasks is improved, and the first control module and the second control module can work more stably under the condition of reduced workload.
Referring to fig. 5, the method for performing multiple tasks provided in the present application is applied to an electronic device, where the electronic device includes a first control module, a second control module, and a processor, and two registers are disposed in the processor, and the method includes:
s210: the first control module receives configuration information of a plurality of tasks sent by the second control module.
In one manner, after the first control module receives the configuration information of the plurality of tasks sent by the second control module, the configuration information may be stored according to the execution sequence of the tasks, and a waiting instruction is set after the configuration information of each task, so as to generate a multi-task queue summary table as shown in table 2.
TABLE 2
S220: the first control module sends configuration information of a task to a first register of the processor, so that the processor can execute the corresponding task based on the configuration information in the first register, and the first register is any one of two registers included in the processor.
S230: before the processor completes the task corresponding to the configuration information in the first register, the first control module sends the configuration information of one task in the remaining tasks to a second register of the processor, wherein the second register is a register in which the configuration information is not written in the registers included in the processor.
S240: and after the first control module sends the configuration information to the processor, executing a waiting instruction to enter a waiting state.
In one manner, after the first control module sends the configuration information of one task to the processor, the first control module may execute the waiting instruction corresponding to the current task according to the sequence in table 2 to enter a waiting state, where the first control module does not continue to send the configuration information to the processor.
S250: and the first control module in the waiting state responds to the task execution completion notification sent by the processor, and sends the configuration information of one task in the rest tasks to a register in the processor, which stores the configuration information corresponding to the task execution completion notification, until the tasks are executed by the processor.
In this embodiment, as shown in fig. 6, the electronic device is further provided with a communication bus, such as a peripheral bus (Advanced Peripheral Bus, APB), or the like. In one mode, the first control module responds to the task execution completion notification sent by the processor, can recover to a normal working state from a waiting state, and sends configuration information of one task in the remaining tasks to a target register in the processor through a communication bus.
Optionally, the communication bus may be further used to implement signal transmission between the first control module, the second control module, and the processor, transmission of task data, and so on.
Optionally, a through passage is connected between the first control module and the processor. As one approach, the processor may send a task execution completion notification to the first control module via the pass-through path. By using the task execution completion notification sent to the first control module by the through channel, the transmission efficiency of the task execution completion notification can be improved, thereby improving the communication efficiency between the processor and the first control module.
S260: the processor sends an interrupt signal to the second control module, wherein the interrupt signal is used for notifying the second control module that the tasks are all completely executed, so that the second control module sends configuration information of the new tasks to the first control module.
Wherein, as a way, after all tasks in table 2 of step S210 are executed by the processor, the processor may send an interrupt signal to the second control module through the communication bus, so that the second control module sends configuration information of the new multiple tasks to the first control module.
According to the multi-task execution method provided by the embodiment, in the process of controlling the processor to execute tasks, the second control module can be responsible for acquiring configuration information of tasks to be executed, and the first control module is responsible for interaction with the configuration information of the tasks to be executed by the processor, so that the first control module and the second control module can work cooperatively, the workload of a single control module is reduced, the efficiency of the processor for processing a plurality of tasks is improved, and the first control module and the second control module can work more stably under the condition of reduced workload. In addition, in this embodiment, by adding a control module (e.g., a first control module), the first control module and the second control module can perform interactive control on the processor, so that not only the workload of the second control module (e.g., an MCU) can be reduced, but also the delay in the task processing process can be reduced, so that the switching between tasks is faster and more efficient.

The register being used by the processor may be understood as a register in which a task corresponding to the stored configuration information is being executed by the processor.

Illustratively, when the processor is currently processing a task corresponding to the configuration information in the first register, the first register is a working register, and the second register is a shadow register; when the processor is currently processing a task corresponding to the configuration information in the second register, the first register is a shadow register, and the second register is a working register.
