Since the application scenarios and access models of embedded systems are diverse, different scenarios and access models have different performance and power consumption requirements.

[0033] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0034] Most related technologies use a method of implementing low power management with fixed intervals of various low power states. This method is not flexible enough and cannot be dynamically adjusted according to real business scenarios. This easily leads to the fact that most products can only find a timing parameter that covers typical use case scenarios as much as possible based on preliminary scenario analysis.

[0035] Figure 1 A protocol diagram of a low-power management method in a self-refresh state provided for an embodiment of the present disclosure. The self-refresh state is a special low-power state in which the memory can automatically refresh to keep data from being lost. The protocol specifies the time interval from exiting the self-refresh state to the arrival of a new command, and this time interval varies depending on the capacity of the memory particles. Since the timing constraints of particles 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 conventional operating process is not very sensitive to this difference.

[0036] The low-power management method in the related art takes all scenarios into consideration in a balanced manner. On the basis of ensuring that the performance and power consumption data of typical scenarios meet the standards, a unified threshold is set to determine the time required to enter or exit different low-power 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. Setting a unified threshold will result in the inability to adapt to all scenarios and different access models.

[0037] In order to solve the problems existing in the related technologies, the present invention proposes a low-power management method, which monitors access behavior in real-time user usage scenarios and dynamically adjusts the strategy of entering low power consumption, so that the embedded system can guarantee performance requirements in scenarios with high bandwidth and high access volume, while optimizing power consumption in scenarios with no access or sparse access, achieving better energy efficiency and avoiding power consumption waste and performance loss.

[0038] The method proposed in the present disclosure can be applied to the field of energy efficiency tuning related to power consumption of dynamic random access memory (DRAM) in embedded system memory, and can also be applied to other technical fields. For example, it can be applied to power consumption management of other embedded systems, such as microcontrollers, sensor nodes, etc., which is not limited in the embodiments of the present disclosure.

[0039] Figure 2 A schematic diagram of the state machine transition timing of DRAM under the JEDEC LPDDRX protocol provided in the embodiment of the present disclosure involves a variety of low-power states, including idle, idle power down, self refresh, and deep sleep mode. Each state has specific timing requirements for entry and exit, and it also takes a certain amount of time to enter or exit 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 consumption management method provided by the present application is described in detail below with reference to the accompanying drawings.

[0041] Figure 3 A flowchart of a low power consumption management method provided by an embodiment of the present disclosure. Figure 3 As shown, the low power consumption management method includes steps 101-103.

[0042] Step 101, obtaining a first time and a second time when the memory and the controller are in a low power consumption state, wherein the first time includes the time required for the memory and the controller to enter the low power consumption state, and the second time includes the time required for the memory and the controller to exit the low power consumption state.

[0043] In an embodiment of the present disclosure, the memory may be a dynamic random access memory (DRAM), which is a common type of memory that uses a capacitor to store charge to store data. DRAM is characterized by high speed and low price, but requires regular refresh to maintain data. Depending on different application scenarios and requirements, there are various types of DRAM, such as SDRAM (synchronous dynamic random access memory), DDRAM (double data rate dynamic random access memory), etc. In embedded systems, DRAM is typically used to store program code, data, etc. The controller may be a controller of a SOC, which is called a system-on-chip, also known as a system on chip, and is an integrated circuit with a dedicated target, which contains a complete system and all the contents of embedded software.

[0044] The low power state refers to a state in which the memory and controller are used to reduce power consumption while maintaining data storage. For example, in embedded systems and mobile devices, different low power states are usually used to extend the battery life of the device. The memory and 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 based on actual conditions and is not limited in the embodiments of the present disclosure.

[0045] The first time (Tlpe) refers to the time required for the memory and controller to enter the low power state. The first time includes the time required for the memory and controller to actually enter the low power state from the time when the memory and controller respond to the instruction to enter the low power state sent by the embedded system or the memory and controller itself. The second time (Tlpx) refers to the time required for the memory and controller to exit the low power state, that is, the time required for the memory and controller to actually exit the low power state from the time when the memory and controller respond to the instruction to exit the low power state sent by the embedded system or the memory and controller itself. Among them, the first time and the second time can be specifically obtained through the connection interaction time between the memory grain side and the system chip (System on Chip, SOC) controller side. The first time can specifically include the first time of the memory grain side and the controller side. Similarly, the second time can specifically include the second time of the memory grain side and the controller side.

[0046] It is understandable that in embedded systems, the power consumption management of the system can be properly arranged according to the low power consumption state and timing requirements of the memory and controller to achieve a better balance between performance and power consumption.

[0047] Step 102: Acquire access information of the memory, where the access information is related to the user's operation.

[0048] In the embodiments of the present disclosure, the user's access behavior can be detected to obtain access information, which is related to the user's operation. The access behavior may include the user's page dwell time, access frequency, access sequence, etc. According to the user's current access behavior, the access scenario corresponding to the access behavior is analyzed. The access scenario refers to the application scenario of the user's current access process obtained through the access behavior. At the same time, the user's access model can be obtained based on the access behavior. The access model may include information such as the user's behavior pattern, interests and hobbies, and access habits.

[0049] Step 103: adjust the first time based on the access information, the first time and the second time.

[0050] In an embodiment of the present disclosure, state transition information in the current low power consumption 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 suitable for the current access scenario and access model.

[0051] It is understandable that, because in actual situations the second time mostly uses the minimum value by default, the present disclosure mainly adjusts the first time.

[0052] In summary, according to the low power management method proposed in the present invention, by obtaining the first time and the second time when the memory and the controller are in the low power state, 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; obtaining the access information of the memory, the access information is related to the user's operation; based on the access information, the first time and the second time, adjusting the first time, by dynamically adjusting the time required to enter the low power state, it can better adapt to different application scenarios, achieve more refined low power management, and avoid power consumption waste and performance loss.

[0053] based on Figure 4 The embodiment shown, Figure 4 The following further illustrates a flow chart of a low power consumption management method proposed in the present disclosure. Figure 4 based on Figure 3 In the embodiment shown, step 103 is further defined. Figure 4 In the embodiment shown, step 103 includes step 203 and step 204. The method is applied to low power consumption management scenarios, such as Figure 4 As shown, the method comprises the following steps:

[0054] Step 201 , obtaining a first time and a second time when the memory and the controller are in a low power consumption state.

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

[0056] In an optional embodiment of the present disclosure, through the connection between the storage crystal grain and the controller, the time-consuming lists Tlpe and Tlpx of the grain side and the soc side of the memory in different low-power states can be directly obtained. Among them, Tlpe refers to the first time, Tlpx refers to the second time, the grain side refers to some grains in the memory, that is, the storage crystal grain of the present disclosure, and the soc side can specifically refer to the controller connected to the memory.

[0057] Step 202: monitor the user's access behavior and obtain access information, which includes access scenarios and access models.

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

[0059] Step 203: determine the state transition information of the low power state in the access scenario, where the state transition information includes the number of times the memory enters the low power state and the running time in the low power state.

[0060] In an embodiment of the present disclosure, state transition information of a low power consumption state in an access scenario in the current access information 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 state transition information of the current embedded system access scenario under idleness within a period of time, such as the number of times low power consumption is entered, the length of time of entering low power consumption, and other information.

[0062] Idle degree refers to the state of an embedded system when there are no tasks to be processed or no user operations for a period of time. It should be noted that idle degree is not necessarily equivalent to low power consumption state. Low power consumption state means that the system further reduces energy consumption by reducing power consumption technology in idle state, such as shutting down unnecessary hardware devices, reducing CPU frequency, etc. Therefore, idle degree and low power consumption state are two different concepts, but there is a certain relationship between them. In an embedded system, the idle degree of the system can be monitored to determine whether it is necessary to enter a low power consumption state to further reduce the power consumption of the system.

[0063] In an embodiment of the present disclosure, the state transition information is obtained through the hardware of the chip in the memory.

[0064] Step 204: adjust the first time based on the access information, the state transition information, the first time, and the second time.

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

[0066] In an embodiment of the present disclosure, the judgment data includes a working time ratio and a first state transition ratio. Determining the judgment data within a preset period may include: based on the access interval, the first time, the second time and the state transition information, obtaining a fourth time, a fifth time, a working time, a third time and a second number, the third time including the time required for the memory and the controller to actually enter a low power state within the preset period, the working time including the time required for the data path to operate normally within the preset period, the second number including the first number of times the memory enters a low power state under an access scenario within the preset period, the fourth time including the first time in the low power state within the preset period, and the fifth time including the second time in the low power state within the preset period; determining the working time ratio based on the working time within the preset period and the preset period; determining the first state transition ratio based on the fourth time, the fifth time, the second number and the third time within the preset period.

[0067] In an embodiment of the present disclosure, based on the judgment data, adjusting the first time may include: if the judgment data meets the first preset condition, increasing the first time; if the judgment data meets the second preset condition, reducing the first time. The first preset condition includes that the working time ratio is greater than or equal to the first preset threshold; the second preset condition includes that the working time ratio is less than the first preset threshold, and the first state transition ratio is greater than or equal to the second preset threshold.

[0068] In an optional embodiment of the present disclosure, it is necessary to obtain power consumption data according to the current access scenario, that is, to actually measure the power consumption data under the current access scenario. According to the power consumption data and the access model extracted by Pattern Trace, the access interval is counted to determine the judgment data. Specifically, as shown in Formula 1

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

[0070] Among them, Tall represents the preset cycle, that is, a single monitoring cycle set in advance. Tbusy represents the working time within the preset cycle, that is, the length of time that the power consumption data works normally in the data path. Tlp represents the third time, that is, the length of time it actually enters the low power consumption state within the preset cycle. n is the number of times, that is, the number of times it enters the low power consumption state within the preset cycle. Tlpe represents the first time within the preset cycle, that is, the time it takes to enter the low power consumption state within the preset cycle, including the software idle waiting time and the hardware state machine time. Tlpx represents the second time within the preset cycle, that is, the time it takes to exit low power consumption within the preset cycle.

[0071] It can be understood that through the data in formula 1, we can get as well as n(Tlpe+Tlpx) represents the first state transition coefficient, that is, the proportional coefficient between the duration of staying in different low-power states and the time taken for the hardware to enter and exit. Indicates the conversion ratio of the first state. Indicates the proportion of working time.

[0072] According to the first state transition ratio and working time ratio obtained by formula 1, the classic configuration values ​​in different low power states are adjusted according to the access scenario in the access information:

[0073] For example: In the overload scenario When it is greater than or equal to the first preset threshold, the duration of Tlpe is increased. In the present disclosure, the specific increase can be determined according to actual conditions and needs, and is not limited in the embodiments of the present disclosure. For example, the original Tlpe duration can be multiplied by 2 or 4 to achieve the purpose of reducing the entry into low power consumption scenarios.

[0074] The choice of multiplying by 2 or 4 may need to be weighed and selected according to the actual situation. If the system has high requirements for performance and can withstand high energy consumption, you can choose to multiply by 4 and extend the software's Tlpe time four times. If the system has high requirements for energy consumption and needs to reduce energy consumption as much as possible, you can choose to multiply by 2 and extend the software's Tlpe time twice.

[0075] In intermittent sparse access scenarios, is less than a first preset threshold, and When it is greater than or equal to the second preset threshold, the duration of the software Tlpe is reduced. In the present disclosure, the specific reduction amount can be determined according to actual conditions and needs, and is not limited in the embodiments of the present disclosure. For example, the original parameters can be divided by 2 or 4 to achieve the purpose of increasing Tlp.

[0076] The choice of dividing by 2 or dividing by 4 may need to be weighed and selected according to the actual situation. If the embedded system has a high requirement for response speed and hopes to respond to user requests faster, you can choose to divide by 2 to shorten the software's Tlpe time by half. If the system has a high requirement for energy consumption and needs to reduce energy consumption as much as possible, you can choose to divide by 4 to shorten the software's Tlpe time by three quarters.

[0077] like Figure 5 As shown, the power consumption data of the SOC side in the memory is compared with the power consumption data of each channel in the idle state after the first adjustment. It can be seen that the low power consumption management method disclosed in the present invention can make the power consumption data of each channel achieve low power consumption characteristics while meeting performance requirements.

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