Since the application scenarios and access models of embedded systems are diverse, different scenarios and access models have different performance and power consumption requirements, and setting a unified threshold will result in the inability to adapt to all scenarios and different access models.

[0033] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings, in which examples of embodiments are shown, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The following describes the embodiments by referring to the accompanying drawings.

[0034] Most of the related technologies use a fixed low-power consumption state interval period to implement a low-power consumption management method, which is not flexible and cannot be dynamically adjusted according to real business scenarios. This can easily lead to most products being able to find a timing parameter that covers typical use case scenarios as much as possible according to early scene analysis.

[0035] Figure 1 A protocol schematic diagram of a low-power consumption management method provided for an embodiment of the present disclosure in a self-refresh state, the self-refresh state is a special low-power consumption state, in which the memory can maintain data without loss through automatic refreshing. The protocol specifies the time interval from exiting the self-refresh state to the arrival of a new command, which varies with the capacity of the memory grain. Since the timing constraints of grains of different capacities are different, the time required to exit the self-refresh state is also different on platforms of different capacities. However, the magnitude of this time difference is usually small, and the regular operation process does not perceive this difference much.

[0036] The low-power consumption management method in the related technology considers all scenarios equally, and on the basis of ensuring that the performance and power consumption data of typical scenarios meet the standards, a uniform threshold is set to determine the time required to enter or exit different low-power consumption states. Since the application scenarios and access models of embedded systems are diverse, different scenarios and access models have different performance and power consumption requirements, and setting a uniform threshold will result in the inability to adapt to all scenarios and different access models.

[0037] To solve the problems in the related art, the present disclosure provides a low-power management method. By monitoring access behavior in real-time user usage scenarios, the strategy of entering low power is dynamically adjusted, so that the embedded system can guarantee the performance requirements in the scene of high bandwidth and high access volume, and optimize power consumption in the scene of no access or sparse access, achieve better energy efficiency ratio, and avoid power waste and performance loss.

[0038] The method provided by the present disclosure can be applied to the field of dynamic random access memory (DRAM) power-related energy efficiency optimization in embedded systems, and can also be applied to other technical fields, for example, can be applied to power management of other embedded systems such as microcontrollers and sensor nodes, and is not limited in the embodiments of the present disclosure.

[0039] Figure 2 A state machine transition timing diagram of DRAM under JEDEC lpddrx protocol is provided for the embodiments of the present disclosure. The state machine transition timing diagram of DRAM involves a plurality of low-power states, including idle, idle power down, self refresh, and deep sleep mode. The entry and exit of each state have specific timing requirements, and a certain time consumption is also required for entering or exiting different low-power states on the controller side. Therefore, in order to maximize the benefits of power consumption and performance, a real-time monitoring mechanism is required.

[0040] The low-power management method provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] Figure 3 A flowchart of a low-power management method is provided for the embodiments of the present disclosure. As shown in Figure 3 The low-power management method includes steps 101-103.

[0042] In step 101, the first time and the second time of the memory and the controller in the low-power state are obtained. The first time includes the time required for the memory and the controller to enter the low-power state, and the second time includes the time required for the memory and the controller to exit the low-power state.

[0043] In embodiments of the present disclosure, the memory can be a dynamic random access memory (DRAM), which is a common type of memory that stores data using capacitors to store electrical charge. DRAM is characterized by fast speed and low price, but needs to be refreshed regularly to maintain data. There are various types of DRAM according to different application scenarios and requirements, such as SDRAM (synchronous dynamic random access memory), DDRAM (double data rate dynamic random access memory), etc. In embedded systems, DRAM is usually used to store program code, data, etc. The controller can be a controller of the SOC, which is also called system on chip (SOC), which is an integrated circuit with a specific target, containing a complete system and all embedded software.

[0044] The low-power state refers to a state in which the memory and the controller are used to reduce power consumption while maintaining data storage. For example, in embedded systems and mobile devices, different low-power states are often used to extend the battery life of the device. The memory and the controller will enter different low-power states, such as sleep state, stop state, etc., to reduce power consumption. In the present disclosure, the low-power state is determined according to the actual situation, and in embodiments of the present disclosure, it is not limited.

[0045] The first time (Tlpe) refers to the time required for the memory and the controller to enter the low-power state. The first time includes the time consumed by the memory and the controller from the start of responding to the instruction of entering the low-power state sent by the embedded system or the memory and the controller itself, to the real entering of the low-power state. The second time (Tlpx) refers to the time required for the memory and the controller to exit the low-power state, i.e. from the start of responding to the instruction of exiting the low-power state sent by the embedded system or the memory and the controller itself, to the real exiting of the low-power state. The first time and the second time can be obtained by the connection interaction time between the memory grain side and the System on Chip (SOC) controller side. The first time can include the first time of the memory grain side and the controller side, and the second time can include the second time of the memory grain side and the controller side.

[0046] It can be understood that in the embedded system, the power management of the system can be reasonably arranged according to the low-power state and timing requirements of the memory and the controller, to achieve better performance and power balance.

[0047] Step 102, access information of the memory is obtained, and the access information is related to the operation of the user.

[0048] In the embodiments of the present disclosure, the access behavior of the user can be detected, and access information related to the operation of the user is obtained. The access behavior can include the page dwell time, access frequency, access sequence, and the like of the user. According to the current access behavior of the user, an access scenario corresponding to the access behavior is analyzed. The access scenario refers to an application scenario in the current access process of the user obtained through the access behavior. Meanwhile, an access model of the user can be obtained according to the access behavior. The access model can include the behavior mode, interest, access habit, and the like of the user.

[0049] In step 103, the first time is adjusted based on the access information, the first time, and the second time.

[0050] In the embodiments of the present disclosure, the state transition information in the current low-power state is determined according to the access information. The first time is adjusted according to the determined state transition information and the first time and the second time. The adjusted first time can be better adapted to the current access scenario and the access model.

[0051] It can be understood that, because the second time is mostly defaulted to the minimum value in actual situations, the first time is mainly adjusted in the present disclosure.

[0052] In summary, according to the low-power management method proposed in the present disclosure, the first time and the second time of the memory and the controller in the low-power state are obtained, the first time includes the time required for the memory and the controller to enter the low-power state, and the second time includes the time required for the memory and the controller to exit the low-power state. The access information of the memory is obtained, and the access information is related to the operation of the user. The first time is adjusted based on the access information, the first time, and the second time. By dynamically adjusting the time required to enter the low-power state, different application scenarios can be better adapted to, more precise low-power management can be achieved, and power waste and performance loss can be avoided.

[0053] Based on the embodiments shown in Figure 4 , the present disclosure further illustrates a flowchart of a low-power management method. Figure 4 Based on the embodiments shown in Figure 4 , the present disclosure further illustrates a flowchart of a low-power management method. Figure 3 Based on the embodiments shown in Figure 4 , the present disclosure further illustrates a flowchart of a low-power management method. Figure 4 Based on the embodiments shown in , the present disclosure further illustrates a flowchart of a low-power management method.

[0054] In step 201, the first time and the second time of the memory and the controller in the low-power state are obtained.

[0055] In an embodiment of the present disclosure, the memory includes memory dies, and the first time and the second time are determined according to an interaction time between the memory dies and the controller.

[0056] In an optional embodiment of the present disclosure, through a connection between the memory dies and the controller, a time consumption list Tlpe and Tlpx of the particle side and the soc side of the memory in different low-power states can be directly obtained. Tlpe refers to the first time, Tlpx refers to the second time, the particle side refers to part of the particles in the memory, i.e., the memory dies of the present disclosure, and the soc side can specifically refer to the controller connected with the memory.

[0057] In an embodiment of the present disclosure, the access information includes an access scenario and an access model.

[0058] In an embodiment of the present disclosure, the current access scenario and the access model are obtained by monitoring the access behavior of the user. The access model can be obtained by processing the access behavior through a pattern trace technology (Pattern Trace). Pattern Trace is a technology for analyzing and extracting the access model of a system, which extracts relevant information by monitoring the access behavior. In Pattern Trace, information in the access behavior, such as address, length, period, etc., can be monitored and recorded. Pattern Trace obtains the access model by analyzing these information.

[0059] In an embodiment of the present disclosure, the state transition information of the low-power state in the access scenario is determined based on the access information.

[0060] In an embodiment of the present disclosure, the state transition information of the low-power state in the access scenario is determined based on the access information.

[0061] In an optional embodiment of the present disclosure, a hardware or software processing mechanism is used to obtain the state transition information of the current embedded system access scenario in a period of time under the idle degree, such as the number of times of entering the low-power state, the length of time of entering the low-power state, and the like.

[0062] The idle degree refers to a state that the embedded system has no task to process or no user operation in a period of time. It is to be noted that the idle degree is not necessarily equivalent to the low-power state, and the low-power state refers to that the system is in the idle state, and further reduces the energy consumption by reducing the power consumption technology, for example, shutting down unnecessary hardware devices, reducing the CPU frequency, and the like. Therefore, the idle degree and the low-power state are two different concepts, but they have certain correlation. In the embedded system, whether the low-power state needs to be entered can be determined by monitoring the idle degree of the system, so as to further reduce the power consumption of the system.

[0063] In the embodiment of the present disclosure, the state transition information is acquired by the hardware of the memory chip.

[0064] In step 204, the first time is adjusted based on the access information, the state transition information, the first time, and the second time.

[0065] In the embodiment of the present disclosure, the power consumption data in the access scenario is acquired; the access interval is counted based on the power consumption data and the access model, the access interval including a time interval between executing adjacent two access behaviors; the judgment data in the preset period is determined based on the access interval, the first time, the second time, and the state transition information; and the first time is adjusted based on the judgment data.

[0066] In the embodiment of the present disclosure, the judgment data includes the working time proportion and the first state transition proportion, and the judgment data in the preset period can include: the fourth time, the fifth time, the working time, the third time, and the second number of times are acquired based on the access interval, the first time, the second time, and the state transition information, the third time including a time required for the memory and the controller to actually enter the low-power state in the preset period, the working time including a time required for the data channel to normally work in the preset period, the second number of times including a first number of times that the memory enters the low-power state in the access scenario in the preset period, the fourth time including the first time in the low-power state in the preset period, and the fifth time including the second time in the low-power state in the preset period; the working time proportion is determined based on the working time in the preset period and the preset period; and the first state transition proportion is determined based on the fourth time, the fifth time, the second number of times, and the third time in the preset period.

[0067] In the embodiment of the present disclosure, the first time is adjusted based on the judgment data can include: if the judgment data meets a first preset condition, the first time is increased; and if the judgment data meets a second preset condition, the first time is reduced. The first preset condition includes that the working time proportion is greater than or equal to a first preset threshold; and the second preset condition includes that the working time proportion is less than the first preset threshold, and the first state transition proportion is greater than or equal to a second preset threshold.

[0068] In an optional embodiment of the present disclosure, the power consumption data needs to be obtained according to the current access scenario, that is, the power consumption data is actually measured in the current access scenario. According to the power consumption data and the access model extracted by the Pattern Trace, the access interval is counted, and the judgment data is determined. Specifically, as shown in formula 1

[0069] Tall = Tbusy + Tlp + n(Tlpe + Tlpx) Formula 1

[0070] Wherein, Tall represents a preset period, that is, a single monitoring period set in advance. Tbusy represents the working time in the preset period, that is, the length of time of the power consumption data in the normal working time of the data channel. Tlp represents the third time, that is, the length of time of actually entering the low-power state in the preset period. n is the number of times, that is, the number of times of entering the low-power state in the preset period. Tlpe represents the first time in the preset period, that is, the time consumption of entering the low-power state in the preset period, including software idle waiting time and hardware state machine time consumption. Tlpx represents the second time in the preset period, that is, the time consumption of exiting the low-power state in the preset period.

[0071] It can be understood that through the data in formula 1, the following can be obtained And n(Tlpe+Tlpx) represents the first state transition coefficient, that is, the proportional coefficient between the length of time staying in different low-power states and the hardware entering and exiting time consumption. represents the first state transition proportion. represents the working time proportion.

[0072] According to the first state transition proportion and the working time proportion obtained according to formula 1, the classical configuration value in different low-power states is adjusted according to the access scenario in the access information:

[0073] For example: in the heavy load scenario, that is, When greater than or equal to the first preset threshold, the length of Tlpe is increased, and in the present disclosure, how much it is increased can be determined according to actual conditions and requirements, which is not limited in the embodiment of the present disclosure, for example, it can be multiplied by 2 or multiplied by 4 on the basis of the original Tlpe length, so as to achieve the purpose of reducing the entering of the low-power state.

[0074] Wherein, the choice of multiplying by 2 or multiplying by 4 may need to be weighed and selected according to actual conditions. If the system has a relatively high requirement on performance and can bear a large energy consumption, then multiplying by 4 can be selected to extend the Tlpe length of the software by four times. If the system has a relatively high requirement on energy consumption and needs to reduce the energy consumption as much as possible, then multiplying by 2 can be selected to extend the Tlpe length of the software by two times.

[0075] In the intermittent sparse access scenario, Less than the first preset threshold, and Greater than or equal to the second preset threshold, the duration of the software Tlpe is reduced, and in the present disclosure, how much it is reduced can be determined according to actual conditions and requirements, which is not limited in the embodiments of the present disclosure. For example, it can be divided by 2 or 4 based on the original parameters to achieve the purpose of increasing Tlp.

[0076] Wherein, the choice of dividing by 2 or 4 may need to be weighed and selected according to actual conditions. If the embedded system has a relatively high requirement on response speed and wants to respond to the user's request faster, it can choose to divide by 2 to shorten the Tlpe duration of the software by half. If the system has a relatively high requirement on energy consumption and needs to reduce energy consumption as much as possible, it can choose to divide by 4 to shorten the Tlpe duration of the software by four-thirds.

[0077] As Figure 5 shown, it is the comparison of the power consumption data of each path in the low-power state and the idle state after the soc side of the storage is adjusted for the first time. It can be seen that the low-power management method of the present disclosure can make the power consumption data of each path realize the characteristics of low power consumption while meeting the performance requirements.

[0078] In summary, through the method provided by the present disclosure, by monitoring the access behavior in real-time user usage scenarios, the strategy of entering low power consumption is dynamically adjusted. When the amount of data accessed in the memory is large and the access is frequent, the idle duration required to enter low power consumption is extended, and the probability of entering low power consumption at this moment is reduced. Conversely, if there is no access or sparse access in the current time period, the waiting duration for entering low power consumption can be shortened, and the duration of staying in the low power consumption state in this scenario can be increased. Thus, the whole system can be as much as possible to guarantee the performance requirements in the scene of high bandwidth and high access amount, and to optimize the power consumption in the scene of no access or sparse access, so as to realize the adaptive adjustment of the low power consumption strategy.
