[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] See also Figures 1 to 10 The present invention provides a satellite navigation baseband module optimization method, which is applied to the satellite navigation baseband module optimization scenario.

[0067] Since two processors are currently used, the two processors are arranged independently and separately in different positions. The tasks that the two processors are responsible for are inconsistent and it is impossible to optimize the task allocation according to the real-time requirements of the tasks and the current system load. This seriously affects the overall performance of the satellite navigation baseband module. In view of this, the present invention adopts a single dual-core processor to process different tasks through the dual-core processor, and can also optimize the performance of the satellite navigation baseband module according to the real-time requirements of the tasks and the current system load, as described below.

[0068] The optimization methods of satellite navigation baseband module include:

[0069] Step S11: using the dual-core processor to collect original tasks and interrupt loads, the dual-core processor is divided into a first core and a second core;

[0070] Step S12: constructing original task allocation between the first core and the second core based on the heterogeneous scheduling strategy, defining the original task that the first core is responsible for as the first task, and defining the original task that the second core is responsible for as the second task;

[0071] Step S13: Based on the original task, the first core triggers a peripheral management policy, and manages the first task according to the peripheral management policy;

[0072] Step S14: Based on the original task, the second core triggers a task priority management policy, and manages the second task according to the task priority management policy;

[0073] Step S15: collaboratively distributing the interruption load according to the current load capacity of the first core and the current load capacity of the second core.

[0074] The present invention is based on a heterogeneous scheduling strategy, constructs an original task allocation between a first core and a second core, reasonably allocates different tasks to the first core and the second core, and defines the original tasks that the first core and the second core are responsible for processing respectively as the first task and the second task, so that the task allocation can be optimized according to the real-time requirements of the task and the current system load. At the same time, the first task is controlled according to the peripheral management strategy, and the second task is controlled according to the task priority management strategy, thereby realizing refined management and control of the first core and the second core, thereby realizing efficient processing of the first task and the second task and improving the overall performance, and collaboratively allocating the interruption load according to the current load capacity of the first core and the current load capacity of the second core to optimize the satellite navigation baseband module.

[0075] In some embodiments, in the specific implementation process of the present invention, step S11 may include:

[0076] S111: locating the dual-core processor;

[0077] S112: Divide the dual-core processor into the first core and the second core according to the type of the original task.

[0078] Dual-core processors are collected and core allocation is performed for the dual-core processors so that the dual-core processors can be divided according to the original task type and divided into the first core and the second core, so that in-depth management and control can be performed based on the first core and the second core, thereby achieving collaborative interaction between the first core and the second core, and making full use of the first core and the second core. At this time, the first core can be used as a CPU0 business module and match the CPU0 business function, and the second core can be used as a CPU1 business module and match the CPU1 business function.

[0079] At this time, the use of the dual-core processor to collect original tasks and interrupt loads includes: detecting the status of the satellite navigation baseband module; and if the satellite navigation baseband module is in an interrupt state, the dual-core processor collects the interrupt load in real time, thereby defining the interrupt load, and controlling the interrupt load.

[0080] In some embodiments, in the specific implementation of the present invention, step S12 may include:

[0081] S121: freeze the first core and the second core;

[0082] S122: Establishing interaction between the first core and the second core, and associating the heterogeneous scheduling strategy;

[0083] S123: constructing original task allocation between the first core and the second core according to the heterogeneous scheduling strategy to define the function of the first core and the function of the second core; and

[0084] S124: Define the original task that the first core is responsible for as the first task according to the function of the first core; and define the original task that the second core is responsible for as the second task according to the function of the second core.

[0085] In certain embodiments of the present application, the first core and the second core are fixed, and the first core and the second core are interacted, so that the first core and the second core are associated with a heterogeneous scheduling strategy, so as to introduce a heterogeneous scheduling strategy into the first core and the second core, and then construct a task allocation between the first core and the second core according to the heterogeneous scheduling strategy to define the functions of the first core and the functions of the second core. Therefore, with respect to the task allocation between the first core and the second core, the workload of the first core and the second core is reasonably allocated, so that one core focuses on real-time satellite navigation signal processing tasks, while the other core processes non-real-time tasks and peripheral interactions, thereby achieving efficient task processing, optimizing power consumption and improving the overall performance of the system.

[0086] At this time, according to the function definition of the first core, the original task that the first core is responsible for is the first task; according to the function definition of the second core, the original task that the second core is responsible for is the second task. Optionally, the first task includes processing non-real-time tasks and peripheral interaction tasks; and the second task includes satellite navigation signal processing tasks.

[0087] Therefore, the first task that the first core is responsible for processing is designated to process non-real-time tasks and all peripheral interaction tasks (such as UART, SPI), and the non-real-time tasks include user interfaces, data interaction applications, etc.; the second core is specifically responsible for real-time satellite navigation signal processing tasks, including baseband signal capture, tracking processing, and processing of high-frequency interrupts related thereto. Optionally, the heterogeneous scheduling mechanism is a software-level scheduler that is responsible for dynamically allocating tasks to the first core and the second core, and optimizing task allocation according to the real-time requirements of the tasks and the current system load. In addition, the use of heterogeneous scheduling strategies can simplify the system design and development process. Developers can optimize the code based on the expertise and task characteristics of each core without having to worry about resource competition and scheduling conflicts between the first core and the second core.

[0088] In some implementations, in the specific implementation process of the present invention, step S13 may include:

[0089] S131: freeze the first core;

[0090] S132: Based on the original task, the first core triggers the peripheral management strategy;

[0091] S133: According to the peripheral management strategy, the first core controls the processing of the non-real-time task and the peripheral interaction task.

[0092] Specifically, according to the peripheral management strategy, the first core forms a task set with the non-real-time task and the peripheral interaction task; constructs a task priority based on the task set; and performs priority processing on the peripheral interaction task.

[0093] In certain embodiments of the present application, the first core is frozen and managed, so that non-real-time tasks and peripheral interaction tasks are collected according to the first core, so as to centrally process the non-real-time tasks and peripheral interaction tasks, and fully guarantee the work content of the first core. At this time, based on the original task, the first core triggers the peripheral management strategy, and according to the peripheral management strategy, the first core manages the processing of the non-real-time tasks and the peripheral interaction tasks.

[0094] Furthermore, non-real-time tasks and peripheral interaction tasks are formed into a task set; task priorities are constructed based on the task set; peripheral interaction tasks are prioritized to trigger peripheral management strategies; at this time, by ensuring the stable execution of peripheral interaction tasks on the non-real-time processing core, the data interruption problem that may be caused by high-frequency real-time task processing is avoided, thereby improving the reliability of data interaction.

[0095] In some embodiments, in the specific implementation process of the present invention, step S14 may include:

[0096] S141: freeze the second core;

[0097] S142: Based on the original task, the second core triggers the task priority management policy;

[0098] S143: According to the task priority management strategy, the second core controls the satellite navigation signal processing task.

[0099] Specifically, according to the task priority management strategy, the second core defines the priority of each subtask in the satellite navigation signal processing task; and triggers the subtasks in an orderly manner based on the priority of each subtask.

[0100] In certain embodiments of the present application, the second core is frozen, and satellite navigation signal processing tasks are collected for the second core, thereby triggering priority processing based on the satellite navigation signal processing tasks, and defining the priorities of each subtask in the satellite navigation signal processing tasks; orderly triggering is performed based on the priorities of each subtask in the satellite navigation signal processing tasks to trigger the task priority management strategy.

[0101] At this time, based on the original task, the second core triggers the task priority management strategy; according to the task priority management strategy, the second core controls the satellite navigation signal processing task; defines the priority of each subtask in the satellite navigation signal processing task; and triggers in an orderly manner based on the priority of each subtask.

[0102] Therefore, by assigning real-time tasks and non-real-time tasks to different cores respectively, the system's processing capability for real-time tasks is significantly improved, while ensuring the stable execution of non-real-time tasks. Therefore, by implementing dual-core heterogeneous scheduling on a dual-core processor, the present invention reduces the hardware cost and design complexity of the system, while reducing the space required inside the chip, thereby improving the system's integration and space efficiency.

[0103] Optionally, through real-time task priority management, a higher priority is assigned to the real-time tasks running on CPU1 to ensure that satellite navigation signal processing and baseband module interrupts can get immediate response. At the same time, the peripheral management strategy is optimized and implemented on CPU0, giving priority to the stability and security of peripheral IO interaction, and avoiding data loss through buffer management and flow control strategy. Figure 7 As shown, the resources between CPU1 and CPU0 interact, such as Figure 8 As indicated, at this time, CPU resource allocation is dynamically adjusted, cache usage strategy is optimized, and the overhead of task switching and interrupt processing is reduced. According to the current workload, the power consumption and performance state of the two cores are dynamically adjusted to achieve energy efficiency optimization.

[0104] In some embodiments, in the specific implementation of the present invention, step S15 may include:

[0105] S151: Obtaining an actual load ratio between the first core and the second core;

[0106] S152: Based on the fact that the actual load ratio is higher than the preset load ratio, load distribution is performed on the first core and the second core until the actual load ratio between the first core and the second core is lower than the preset load ratio.

[0107] In certain embodiments of the present application, the status of the satellite navigation baseband module is detected; if the satellite navigation baseband module is in an interrupt state, the interrupt load of the satellite navigation baseband module is collected in real time to define the interrupt load of the satellite navigation baseband module, thereby dividing the interrupt load of the satellite navigation baseband module to adapt to the first core and the second core.

[0108] In certain embodiments of the present application, the status of the satellite navigation baseband module is detected; if the satellite navigation baseband module is in an interrupt state, the interrupt load of the satellite navigation baseband module is collected in real time to define the interrupt load of the satellite navigation baseband module, thereby dividing the interrupt load of the satellite navigation baseband module to adapt to the first core and the second core.

[0109] Therefore, the interrupt load based on the satellite navigation baseband module triggers the load distribution of the first core and the second core, wherein the actual load ratio between the first core and the second core is obtained, and based on the actual load ratio being higher than the preset load ratio, the first core and the second core are load distributed until the actual load ratio between the first core and the second core is lower than the preset load ratio. Therefore, the interrupt load is collaboratively distributed based on the current load capacity of the first core and the current load capacity of the second core to improve the response speed and processing capability of the satellite navigation baseband module to interrupts. At this time, a priority management system is implemented to ensure that real-time processing tasks (such as baseband module interrupts) can obtain a quick response, while ensuring that non-real-time tasks (such as peripheral IO operations) are not blocked for a long time due to the high-frequency interrupts of real-time tasks.

[0110] At the same time, the load ratio between the first core and the second core is collected; if the load ratio between the first core and the second core is higher than the preset load ratio, the load is distributed for the first core and the second core until the load ratio between the first core and the second core is lower than the preset load ratio, and the power consumption and state of the first core and the second core are dynamically adjusted. At this time, according to the current task load and system performance requirements, the power consumption state of the first core and the second core is dynamically adjusted, such as reducing the CPU frequency or placing non-critical cores in low power mode when the load is low. In addition, a set of efficient inter-core communication mechanisms is designed to support fast data exchange and synchronization, and reduce data transmission and processing delays. The invented dynamic power management strategy effectively reduces the overall power consumption, which is particularly suitable for battery-powered portable satellite navigation devices and prolongs the use time of the device. In addition, an error detection and recovery mechanism is implemented to ensure that the system can recover quickly when encountering abnormal situations, ensuring the stable operation of the system and the security of data.

[0111] In some embodiments, the optimization method of the satellite navigation baseband module also includes: collecting the abnormal state of the satellite navigation baseband module; in the abnormal state, defining the abnormal part of the satellite navigation baseband module; defining the task type according to the abnormal part; triggering the first core or the second core according to the task type; and performing real-time optimization on the abnormal part based on the first core or the second core to restore the normal state of the satellite navigation baseband module, thereby realizing abnormal management and control of the satellite navigation baseband module and ensuring abnormal handling of the satellite navigation baseband module.

[0112] Some embodiments of the present application use a dual-core processor to collect original tasks and interrupt loads, and the dual-core processor is divided into a first core and a second core; based on a heterogeneous scheduling strategy, the original task allocation between the first core and the second core is constructed, and the original task that the first core is responsible for is defined as the first task, and the original task that the second core is responsible for is defined as the second task; based on the original task, the first core triggers the peripheral management strategy, and controls the first task according to the peripheral management strategy; based on the original task, the second core triggers the task priority management strategy, and controls the second task according to the task priority management strategy; and based on the current load capacity of the first core and the current load capacity of the second core, The interrupt load is collaboratively distributed. At this time, based on the heterogeneous scheduling strategy, the original task allocation between the first core and the second core is constructed to facilitate the reasonable allocation of the first task and the second task, thereby optimizing the task allocation according to the real-time requirements of the task and the current system load. At the same time, the first task is controlled according to the peripheral management strategy, and the second task is controlled according to the task priority management strategy, thereby realizing refined management and control of the first core and the second core, thereby realizing efficient processing of the first task and the second task and improving the overall performance, and collaboratively distributing the interrupt load according to the current load capacity of the first core and the current load capacity of the second core to optimize the satellite navigation baseband module.
