[0058] 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.

[0059] Reference Figure 1 A first embodiment of the present invention provides a method for calculating chip power consumption, comprising the following steps:

[0060] S11, performing a region division operation based on the region where the router body is located to obtain a router domain, wherein the router domain is an independent region divided according to the internal function of the router;

[0061] S12, performing a micro-domain division operation according to the router domain to obtain an idle micro-domain and a power micro-domain;

[0062] S13, performing parameter extraction operations in the idle micro-domain and the power micro-domain respectively to obtain idle parameters and power parameters, wherein the idle parameters include leakage current, operating voltage, operating time, capacitance and operating frequency, and the power parameters include output current, output voltage, output time, dynamic power consumption, power micro-domain power consumption in a previous state, and static power consumption in a previous state;

[0063] S14, performing calculation according to the idle parameters to obtain idle micro-domain power consumption;

[0064] S15, performing calculation according to the power supply parameters to obtain the power consumption of the power micro-domain;

[0065] S16, performing weighted calculation according to the idle micro-domain power consumption and the power micro-domain power consumption to obtain idle micro-domain weighted power consumption and power micro-domain weighted power consumption;

[0066] S17, performing a superposition calculation based on the idle micro-domain weighted power consumption and the power micro-domain weighted power consumption to obtain the total power consumption of the router domain.

[0067] In step S11, it is necessary to perform a region division operation based on the region where the router body is located to obtain a router domain, wherein the router domain is an independent region divided according to the internal function of the router, including:

[0068] First, the division of router domains is based on the principle of functional independence. In the actual operation of routers, different modules undertake different functional tasks. Therefore, when dividing router domains, the functional attributes and system structure of the router need to be considered comprehensively. Typical division methods include: processor domain (responsible for data processing and instruction execution), data forwarding domain (management of data packet forwarding and routing operations), switching chip domain (realization of data exchange and signal forwarding) and interface management domain (handling external connections and input / output signal management). Each router domain can independently complete specific tasks and has independent power consumption characteristics, so it can be independently modeled and optimized in power consumption analysis.

[0069] Secondly, the interconnectivity and coordination of each router domain need to be considered during the partitioning process. Although each router domain is independent in terms of power management, in actual operation, the domains need to work together. In order to achieve the best effect in overall power management, the boundaries and communication methods between the domains need to be designed during the partitioning process. For example, the communication between the processor domain and the data forwarding domain involves data flow, signal exchange, etc., and these interactions will also affect power consumption.

[0070] Specifically, the division operation should ensure the independence and manageability of the router domain. Each router domain needs to have certain independent functions and control capabilities, be able to complete the assigned tasks independently, and also be able to cooperate with other router domains.

[0071] In a specific embodiment, the router is divided into router domain. The value of is greater than or equal to 2 to ensure that different functional modules can be distinguished and managed. Each router domain represents an independent functional area with independent task boundaries and power consumption characteristics.

[0072] In step S12, it is necessary to perform a micro-domain division operation according to the router domain to obtain an idle micro-domain and a power micro-domain, including:

[0073] First, the idle micro-domain partitioning aims to identify and manage low-activity or idle state cells within the router domain. The number of idle micro-domains is These micro-domains contain modules that operate in low-load or standby states, such as parts of processor cores, cache memory units, or other infrequently used functional units. By dividing these modules into idle micro-domains, their static power consumption and low dynamic power consumption can be measured and managed independently, providing support for further energy-saving optimization.

[0074] Secondly, the division of power micro-domains is aimed at modules and functional units that require high power consumption support. The number of power micro-domains is These micro-domains include high-frequency operation units of the processor core, switching chip modules, data transmission modules and other high-load task areas. Unlike the idle micro-domain, the power consumption calculation of the power micro-domain needs to take into account more complex dynamic power consumption, operating voltage, output current and load changes.

[0075] In a specific embodiment, the separation and management of idle micro-domains and power micro-domains are particularly important. They correspond to different operating states and energy consumption requirements, so different strategies need to be adopted in power consumption optimization. The idle micro-domain focuses on reducing static energy consumption and managing idle resources, while the power micro-domain needs to optimize the energy efficiency of high-power consumption operations through load management and dynamic adjustment.

[0076] In step S13, it is necessary to perform parameter extraction operations in the idle micro-domain and the power micro-domain, respectively, to obtain idle parameters and power parameters, wherein the idle parameters include leakage current, operating voltage, operating time, capacitance and operating frequency, and the power parameters include output current, output voltage, output time, dynamic power consumption, power micro-domain power consumption in the previous state and static power consumption in the previous state, including:

[0077] In a specific embodiment, the leakage current in an idle micro-domain refers to the tiny current flowing through its components when the micro-domain is in a low load or standby state. It can be directly obtained through hardware sensors such as low-power current sensors such as current probes, which can capture tiny leakage current changes. In addition, the leakage current can also be estimated based on the chip manufacturing process, device characteristics and environmental conditions using a computational model. The model can predict the leakage current change trend under different working environments; the operating voltage refers to the voltage level maintained by the micro-domain in the idle state. This parameter can be monitored by a power management chip. The adjustment and control of the operating voltage is crucial to reducing the power consumption in the idle state, because the change in voltage affects the overall energy consumption of the micro-domain; the operating time indicates the duration of the micro-domain in the idle state, which can be recorded by a timer or a system management program. The operating time is used to evaluate the cumulative effect of idle power consumption and the total energy consumption when idle for a long time; the capacitance in the micro-domain reflects the ability of the circuit to store charge. It can be obtained through circuit design parameters or hardware measurements; the operating frequency indicates the operating frequency of the micro-domain when it is running, which can be monitored by a clock manager.

[0078] In a specific embodiment, the output current represents the current output of the power micro-domain during operation, which can be measured by a current sensor. The output current directly affects the power consumption of the power micro-domain, and a larger output current means a higher energy consumption level; the output voltage represents the voltage output level of the power micro-domain, which can be obtained by a voltage sensor. The output voltage and output current are combined to calculate the power consumption of the power micro-domain to ensure that the output meets the load requirements of the current task; the output time refers to the duration of the power micro-domain in the power supply state. It can be recorded by the system timer. The output time is proportional to the total energy consumption. The extended output time will increase the overall energy consumption of the system; dynamic power consumption: refers to the instantaneous power consumption generated by the power micro-domain during operation. Dynamic power consumption is caused by load changes and state switching, and the calculation formula involves voltage, frequency and signal switching factors. Monitoring of dynamic power consumption helps to adjust the operating state of the system in a timely manner and reduce peak power consumption.

[0079] It should be noted that for the power micro-domain calculation in step S15, it is also necessary to obtain the power micro-domain power consumption of the previous state and the static power consumption of the previous state. The parameter of the power micro-domain power consumption of the previous state reflects the power consumption performance of the power micro-domain in the previous state. The static power consumption of the previous state is similar to the power consumption of the previous state. This parameter is specifically for recording static energy consumption. Static power consumption is mainly composed of leakage current and energy consumption in other inactive states. During the operation of the power micro-domain, the system will use the power consumption monitoring module to record its power consumption data in real time. These data will be stored in the system log or dedicated storage area. When it is necessary to obtain the power consumption of the previous state, it can be read directly from these historical records.

[0080] In step S14, it is necessary to calculate according to the idle parameters to obtain the idle micro-domain power consumption, including:

[0081] First, according to the leakage current, operating voltage and operating time of the idle micro-domain extracted in step S13, calculation is performed to obtain static power consumption. The static power consumption mainly refers to the energy consumption caused by the leakage current when the micro-domain is inactive or low-load state. The calculation formula of the static power consumption is:

[0082]

[0083] In the formula, For the Router domain The static power consumption of an idle micro-domain; For the Router domain The leakage current of an idle micro-domain; For the Router domain The operating voltage of an idle micro-domain;

[0084] Next, according to the capacitance, operating voltage and operating frequency of the idle micro-domain extracted in step S13, calculation is performed to obtain dynamic power consumption. Dynamic power consumption means that although the micro-domain is in an idle state, it needs to maintain basic signal switching or periodic activities, which will cause dynamic power consumption. The calculation formula of the dynamic power consumption is:

[0085]

[0086] In the formula, For the Router domain Dynamic loss of idle micro-domains; is the signal switching factor; For the Router domain The capacitance of an idle micro-domain; is the operating frequency;

[0087] It should be noted that is the signal switching factor, The acquisition of is achieved through experimental measurement, simulation tools and design parameter reference. For example, the power consumption change of the circuit can be measured by using a test board in a laboratory environment. In this process, a standardized switching signal sequence (such as a pulse signal with gradually increasing frequency) is input into the micro domain, and then a power consumption measurement instrument (such as a power analyzer) is used to record the power consumption change at different switching rates. By calculating the rate of change of power consumption at different switching frequencies, the signal switching factor can be derived. ; Use the simulation module of electronic design automation (EDA) tools such as Cadence, Synopsys, or Mentor Graphics to simulate the circuit. By running signal switching analysis in the simulation environment, you can get the impact of signal activity on power consumption. The simulation results will give a detailed report on dynamic power consumption and signal switching, from which you can extract and calculate ; During the design phase, you can refer to the typical signal switching factor values ​​given in the relevant process nodes or design manuals. For example, for some common CMOS process nodes, using 28nm process node logic circuits, the design manual will provide typical A range of values ​​based on which preliminary calculations and adjustments can be made.

[0088] Next, the idle micro-domain power consumption is calculated based on the static power consumption and the dynamic power consumption, wherein the calculation formula of the idle micro-domain power consumption is:

[0089]

[0090] In the formula, For the Router domain The idle micro-domain power consumption of an idle micro-domain.

[0091] In step S15, it is necessary to calculate according to the power supply parameters to obtain the power micro-domain power consumption, including:

[0092] First, according to the output time, output current and output voltage of the power micro-domain extracted in step S13, the static power consumption of the power micro-domain is calculated. The static power consumption of the power micro-domain refers to the basic energy consumption of the micro-domain under the power supply state, which is mainly determined by the output time, output current and output voltage. The calculation formula of the static power consumption of the power micro-domain is:

[0093]

[0094] In the formula, For the Router domain The static power consumption of each power micro-domain; For the Router domain Output current of each power micro-domain; For the Router domain Output voltage of each power micro-domain; For the Router domain Output time of each power micro-domain;

[0095] Next, according to the power micro-domain static power consumption, dynamic power consumption, power micro-domain power consumption of the previous state and static power consumption of the previous state extracted in step S13, calculation is performed to obtain the power micro-domain power consumption, wherein the calculation formula of the power micro-domain power consumption is:

[0096]

[0097] For the Router domain The power consumption of each power micro-domain; For the Router domain Dynamic power consumption of each power micro-domain; For the The previous state of the router domain is The power consumption of each power micro-domain; For the The previous state of the router domain is The static power consumption of each power micro-domain.

[0098] Specifically, by combining the static power consumption of the current state with the power consumption of the previous state, the total energy consumption of the power micro-domain in different operating states can be estimated more accurately. The calculation of total power consumption not only considers the energy consumption characteristics of the current state, but also integrates the influence of the historical state, providing basic support for power consumption calculation and optimization.

[0099] In step S16, it is necessary to perform weighted calculation according to the idle micro-domain power consumption and the power micro-domain power consumption to obtain the idle micro-domain weighted power consumption and the power micro-domain weighted power consumption, including:

[0100] In a specific embodiment, the weighted power consumption of the idle micro-domain is weighted processing of the idle micro-domain power consumption of the idle micro-domain to reflect the influence of the power consumption in the idle state, wherein the calculation formula of the weighted power consumption of the idle micro-domain is:

[0101]

[0102] In the formula, For the Router domain The weighted power consumption of idle micro-domains; is the idle weighting factor; For the Router domain The idle micro-domain power consumption of the idle micro-domains;

[0103] It should be noted that in the weighted calculation, the idle weighting factor is used to weight the basic power consumption of the idle micro-domain to reflect the impact of the power consumption in the idle state on the total energy consumption of the system. Its main function is to control the weight of the idle micro-domain power consumption in the overall power consumption management so that it can be flexibly adjusted under different optimization strategies. The setting is based on system requirements and application scenarios. For example, if the idle state has a greater impact on energy consumption (for example, the system is idle for a long time), you can increase The value of makes the idle state power consumption account for a higher proportion of the total energy consumption, thereby guiding the optimization strategy to reduce the idle power consumption. On the contrary, for idle micro-domains with less impact, the value to reduce its weight.

[0104] For example, in a data center, if the server is frequently idle, the value, making idle power consumption optimization the focus of energy efficiency management.

[0105] In a specific embodiment, the weighted power consumption of the power micro-domain is used to reflect the energy consumption impact of the power micro-domain under load operation, wherein the calculation formula of the weighted power consumption of the power micro-domain is:

[0106]

[0107] In the formula, For the Router domain The power micro-domain weighted power consumption of each power micro-domain; is the power weighting factor; For the Router domain The power micro-domain power consumption of each power micro-domain.

[0108] It should be noted that in the weighted calculation, the power weighting factor is used to adjust the power consumption weight of the power micro-domain, reflecting its impact on the total power consumption of the system under load operation. This factor weights the power consumption of the power micro-domain so that it occupies a suitable position in the total energy consumption, ensuring that it receives sufficient attention in system optimization. Usually, the power micro-domain undertakes the main load tasks and makes a greater contribution to the overall energy consumption of the system. Therefore, It is often set to a higher value to ensure that its influence in the overall energy consumption management is taken into account. If the load fluctuation of the power micro-domain is large during system operation, increase The value can help control the energy consumption performance under high load conditions.

[0109] For example, in a high-performance computing system, the power micro-domain carries a large amount of data computing tasks. value, the optimization focus can be placed on high-load power consumption control during operation, thereby improving the overall system efficiency.

[0110] In step S17, it is necessary to perform a superposition calculation based on the idle micro-domain weighted power consumption and the power micro-domain weighted power consumption to obtain the total power consumption of the router domain, including:

[0111] In a specific embodiment, in order to calculate the total power consumption of the router domain, it is necessary to superimpose the weighted power consumption of all idle micro-domains and the weighted power consumption of the power micro-domain. This process weights and accumulates the power consumption contribution of each micro-domain to finally obtain the total energy consumption of the entire router domain, wherein the calculation formula for the total power consumption of the router domain is:

[0112]

[0113] In the formula, is the total power consumption of the router domain; is the total number of router domains; is the total number of idle micro-domains; is the total number of power micro-domains; For the Router domain The weighted power consumption of idle micro-domains; For the Router domain The weighted power consumption of the power micro-domains of the power micro-domains.

[0114] It should be noted that is the total number of router domains, which refers to the number of router domains divided in the entire system; is the total number of idle micro-domains, i.e., the number of idle micro-domains in each router domain; is the total number of power micro-domains, that is, the number of power micro-domains in each router domain.

[0115] The following describes the working process of the present invention using a common scenario as an example. Figure 2 , which is Figure 1 Schematic diagram of the working scenario of the method.

[0116] In a large data center, routers need to process a large amount of network data traffic, and their load status will fluctuate significantly over time and with changes in business needs. In order to optimize the energy efficiency of routers, the present invention provides a sophisticated power consumption management solution to divide different functional modules and accurately calculate and manage power consumption. First, the router is divided into multiple independent functional domains, including a processor domain, a data forwarding domain, a switching chip domain, and an interface management domain. Each functional domain independently undertakes specific tasks and has independent power consumption characteristics. For example, when the data traffic is large, the processor domain needs to process a large number of data tasks, and its power consumption increases significantly; while in a low load or idle state, its power consumption is mainly composed of static power consumption. Therefore, dividing the functional domains can more accurately manage the power consumption of different modules and improve the energy efficiency of the overall system.

[0117] After completing the division of router domains, the present invention further subdivides each router domain into idle micro-domains and power micro-domains. Idle micro-domains are mainly used to manage modules in low activity or standby state. For example, during low traffic peaks, some processor cores or cache modules will enter an idle state. For the power consumption management of these micro-domains, special attention should be paid to static power consumption and low dynamic power consumption. Taking a processor core as an example, when it enters the idle state, its leakage current is 10mA and the operating voltage is 1.2V. According to the formula, its static power consumption is calculated as:

[0118]

[0119] In addition, by calculating the dynamic power consumption, assuming that the capacitance is 50pF, the signal switching frequency is 100MHz, and the signal switching factor is 0.5, the dynamic power consumption is calculated as:

[0120] The total idle micro-domain power consumption is:

[0121]

[0122] For the power micro-domain, the main management requires modules that require high power consumption support, such as high-frequency processor cores and data exchange modules. When the data traffic is high, these micro-domains need to process a large number of data tasks, and their power consumption management needs to consider dynamic power consumption and complex load changes. Assuming that the output time of the power micro-domain is 1 second, the output current is 2A, and the output voltage is 3.3V, its static power consumption is calculated as:

[0123]

[0124] After completing the power consumption calculation of the idle micro-domain and the power micro-domain, the present invention introduces a weighting factor to perform weighted processing on the power consumption. The idle weighting factor is used to adjust the weight of the idle micro-domain in the total energy consumption. Especially in the idle state for a long time, the idle power consumption can be better optimized by increasing the weighting factor. The power weighting factor is used to adjust the power consumption weight of the power micro-domain under high load conditions. By increasing its weight, the impact of the power micro-domain on the total energy consumption can be highlighted. In a specific application, assuming that a router domain has 5 idle micro-domains and 3 power micro-domains, the total power consumption is calculated as:

[0125]

[0126] This superposition calculation method can comprehensively reflect the total power consumption performance of each state within the router domain, providing data support and strategy selection for further optimizing the system's power consumption.

[0127] In summary, through refined power consumption management and parameter analysis, routers in data centers can achieve more efficient energy consumption control under high load and low load conditions, reduce unnecessary power consumption, and improve the overall performance and stability of the system.

[0128] In summary, the present invention realizes power consumption analysis in multiple regions by dividing the router into regions, generating independent router domains, and further subdividing them into idle micro-domains and power micro-domains. Unlike traditional methods that only focus on local optimization or simply shut down auxiliary circuits, the present invention can analyze the power consumption of different modules in detail based on the overall system. With the help of a multi-parameter power consumption model, the static and dynamic power consumption of the idle micro-domain and the power micro-domain is calculated. Through weighted calculation of the idle and power micro-domains, flexible weighting factors are used to refine the evaluation of power consumption performance in different states. The total power consumption of the router domain is obtained by superimposing the weighted power consumption of the idle micro-domain and the power micro-domain, realizing multi-region power consumption analysis and comprehensively calculating the total power consumption of the router including the processor and the switching chip.
