Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes.
The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.
Two power supply modes of the current power utilization system are basically described below.
Fig. 1 is a first schematic structural diagram of an electrical system provided in the prior art. As shown in fig. 1, the powered system supports an independent powered scheme. Specifically, after the power is input into the power management unit, the power is output to the N circuits through the N controllable voltage conversion modules to supply power to the power utilization units, wherein the power utilization units can belong to the same chip. The power supply of each power consuming unit is independent. When the performance monitoring unit of one power utilization unit decides that the working frequency of the power utilization unit needs to be adjusted and causes corresponding voltage adjustment, the performance monitoring unit sends a target voltage value Vt to be adjusted to a power consumption management unit in a chip, the power consumption management unit sends an instruction to a power management unit after receiving the instruction, and the power management unit controls a corresponding voltage conversion module to adjust the power supply voltage to Vt. If the voltage regulation is performed for boosting and raising the frequency, the frequency of the power consumption unit is raised after the adjustment of the power supply voltage is completed. If the voltage regulation is for voltage reduction and frequency reduction, the frequency of the power consumption unit is firstly reduced, and then Vt is sent to the power consumption management unit to realize voltage reduction. If the voltage regulation is for boosting and raising the frequency, the voltage to be supplied by the power utilization unit is regulated to Vt, and then the working frequency is increased.
It should be noted that, for the above independent power supply scheme, a plurality of voltage conversion modules are respectively arranged in the power management unit, a plurality of independent power supply pins are arranged on the chip pins, a plurality of independent power supply networks are arranged in the chip, and a voltage conversion module is respectively arranged on the interconnection signal between the power utilization units. The system has high complexity, high power supply overhead and high cost, and cannot be adapted and deployed on a complex chip with a large number of internal power utilization units.
Fig. 2 is a schematic structural diagram of an electric system provided in the prior art. As shown in fig. 2, the powered system supports a combined power scheme. Similar to independent power supply, in the combined power supply scheme, after a power supply is input into a power supply management unit, M paths of power supply are output through M controllable voltage conversion modules. The difference is that the M power supplies are not directly shared by all the power utilization units respectively. Instead, the power-consuming units are grouped, each group forming a voltage domain, and the M circuits supply power to all the power-consuming units in the voltage domain. When the performance monitoring unit of a certain power utilization unit in a certain voltage domain decides that the working frequency of the power utilization unit needs to be adjusted to be Ft, and the corresponding working voltage when the Ft works is Vt, the performance monitoring unit k sends a target voltage value Vt to be adjusted to a power consumption management unit in a chip, after the power consumption management unit receives an instruction, the power consumption management unit synthesizes the working voltage requirements of all N power utilization units in the voltage domain, takes the maximum target working voltage value Vmax to send the instruction to a power supply management unit, and the power supply management unit controls a voltage conversion module to adjust the power supply voltage to Vmax. If the voltage regulation is performed for boosting and raising the frequency, the frequency of the power consumption unit is raised after the voltage regulation is completed. If the adjusted Ft is lower than the previous working frequency, the frequency of the power consumption unit is reduced first, and then the target voltage value to be adjusted is sent to the power consumption management unit. If Ft of this voltage regulation is higher than the previous operating frequency, the power consumption unit waits for the power supply voltage to be adjusted to Vmax (> = Vt), and then increases the operating frequency to Ft.
It should be noted that, for the above-mentioned combined power supply scheme, because a plurality of power consumption units in the same voltage domain share the same power supply, the power supply voltage in the final voltage domain is the maximum voltage value of each power consumption unit, for some power consumption units with lower requirements on operating voltage, the power supply voltage is greater than the required voltage, and the power consumption is increased due to the existence of the voltage excess phenomenon.
In an embodiment of the present application, an electrical system capable of reducing system power consumption is provided, which is described in detail below.
Fig. 3 is a first schematic structural diagram of an electrical system according to an embodiment of the present application. As shown in fig. 3, in an embodiment of the present application, an electricity system includes: a plurality of power consumption units 101 belonging to the same voltage domain, and a plurality of performance management units 102 connected in one-to-one correspondence with the plurality of power consumption units 101;
the power management unit 103 is connected with the plurality of power utilization units 101, and the power management unit 103 is used for providing the same working voltage for the plurality of power utilization units 101;
each performance management unit 102 is configured to determine a target operating frequency corresponding to the power consumption unit connected to the performance management unit according to the operating voltage, and control the power consumption unit 101 connected to the performance management unit to operate at the corresponding target operating frequency.
In the embodiment of the present application, referring to fig. 4, an electric system may be divided into M voltage domains, where M is a natural number not less than 1, a voltage domain 0 may include a certain number of electric units 101, and the operating voltages of the electric units 101 in the same voltage domain are the same.
It should be noted that, in the embodiment of the present application, the specific power utilization units 101 and the number of the power utilization units 101 may be set according to actual needs and application scenarios, and the embodiment of the present application is not limited to this, and the number of the performance management units 102 is consistent with the number of the power utilization units 101 and is connected in a one-to-one correspondence manner.
In an embodiment of the present application, referring to fig. 4, the power management unit 103 includes: and a voltage conversion module 1031, configured to convert an input voltage of the power supply into a working voltage. In addition, the power management unit 103 may further include voltage conversion modules corresponding to other voltage domains.
It should be noted that, in the embodiment of the present application, in order to provide the same operating voltage to the plurality of power utilization units 101 belonging to the same voltage domain, a voltage conversion module 1031 may be disposed in the power management unit 103, so that the input voltage of the power supply is converted by the voltage conversion module 1031, and the converted operating voltage may be provided to each power utilization unit 101, where the magnitude of the operating voltage may be changed by the power management unit 103 controlling the voltage conversion module 1031.
It is understood that, in the embodiment of the present application, for a plurality of power consumption units 101 belonging to the same voltage domain, the voltage conversion module 1031 provides the same operating voltage, and in the actual requirement, there may be a difference in the voltage requirement of each power consumption unit 101, that is, the operating voltage provided by the voltage conversion module 1031 may not conform to the actual operating state of the power consumption unit 101, for example, the operating voltage is too high, for which, each performance management unit 102 may determine the target operating frequency corresponding to the power consumption unit 101 connected thereto according to the operating voltage to perform the operating frequency control.
In an embodiment of the present application, each performance management unit 102 is further configured to: under the condition that the working voltage exceeds an expected voltage value corresponding to the power utilization unit 101 connected with the working voltage, acquiring the current working frequency and the maximum working frequency of the power utilization unit 101 connected with the working voltage;
calculating a first expected power consumption of the power consumption unit 101 connected with the power consumption unit, which operates at the corresponding current operating frequency under the operating voltage, and a second expected power consumption of the power consumption unit, which operates at the corresponding maximum operating frequency;
and determining the maximum working frequency as the target working frequency corresponding to the electric unit connected with the maximum working frequency under the condition that the second expected power consumption is lower than the first expected power consumption.
In an embodiment of the present application, each performance management unit 102 is further configured to: respectively calculating the duty ratio and the dynamic power consumption of the power utilization unit 101 connected with the power utilization unit under the working voltage and working at the corresponding current working frequency;
acquiring the maximum leakage current of the power consumption unit 101 connected with the power consumption unit under the working voltage;
calculating a first expected power consumption according to the maximum leakage current and the dynamic power consumption and the duty ratio of the power consumption unit 101 connected with the maximum leakage current and working at the corresponding current working frequency under the working voltage;
the second expected power consumption is calculated based on the maximum leakage current and the dynamic power consumption and duty cycle of the power consuming unit 101 connected thereto operating at the corresponding maximum operating frequency at the operating voltage.
Fig. 5 is a schematic workflow diagram of an exemplary performance management unit according to an embodiment of the present application. As shown in fig. 5, in the embodiment of the present application, any performance management unit 103 may first obtain the current operating frequency Fc of the power consumption unit 101 connected thereto, and at the same time obtain the highest operating frequency Fmax at which the power consumption unit 101 connected thereto can operate at the current voltage. Generally, if Fmax > Fc, this means that the power unit 101 can have a higher calculation speed when operating at Fmax, but the calculation speed is not generally proportional to the operating frequency, and is also affected by the data and signal conditions of the input and output paths. Further, the performance management unit 103 evaluates the duty cycle Tmax of the power consuming unit 101, which is finally actually operating and idle if it is operating at the frequency Fmax at this time, and the duty cycle Tc of the power consuming unit if it continues to operate at Fx. It can be derived that when the operating voltage of the voltage domain is Vmax, the expected power consumption of the power consumption unit 101 to complete the current task by operating at the frequency Fmax is Tmax (Pmax + Lmax), and the expected power consumption to complete the current task by operating at the frequency Fc is Tc (Pc + Lmax). Where Lmax is the maximum leakage current of the power consumption unit 101 at the current operating voltage. If the power consumption required for operating at the frequency Tmax is lower than the power consumption required for operating at the frequency Tc, the performance management unit 103 determines the frequency Fmax as a target operating frequency corresponding to the power consuming unit 101, thereby controlling the operating frequency of the power consuming unit 101 to be increased to the frequency Pmax.
It should be noted that, in the embodiment of the present application, let the ratio of Tmax to Tc be ρ, and ρ be less than 1, as shown in the following formula:
P1＝Tc×(Pc+Lmax) (1)
P2＝Tmax×(Pmax+Lmax)≈ρTc×(Pc/ρ+Lmax)＝Tc×(Pc+ρLmax) (2)
wherein P1 is the expected power consumption of the power consumption unit 101 operating at the current operating frequency under the operating voltage, and P2 is the expected power consumption of the power consumption unit operating at the maximum operating frequency under the operating voltage, since ρ <1, it can be seen from the above formulas (1) and (2) that P2< P1 under normal conditions, and the power consumption reduction can be realized by frequency up-conversion.
In the embodiment of the present application, each performance management unit 102 is further configured to determine, as a corresponding target operating frequency, a desired operating frequency corresponding to the power consuming unit 101 connected thereto when the operating voltage is a desired voltage value corresponding to the power consuming unit 101 connected thereto; there is a corresponding relationship between the expected operating frequency and the expected voltage value of each power utilization unit 101.
It can be understood that, in the embodiment of the present application, the expected voltage value corresponding to each power consuming unit 101 corresponds to the expected operating frequency, and for any power consuming unit 101, if the magnitude of the operating voltage is the expected voltage value corresponding to the power consuming unit, it is most suitable for operating at the expected operating frequency, and therefore, the expected operating frequency corresponding to the power consuming unit can be directly determined as the target operating frequency.
In an embodiment of the present application, as shown in fig. 4, the power utilization system further includes: a plurality of switching units 104 belonging to the same voltage domain as the plurality of power consuming units 101;
each switch unit 104 is connected between one power utilization unit 101 and the power management unit 103, and is connected with the performance management unit 102 connected with the connected power utilization unit 101;
each performance management unit 102 is further configured to perform a switching decision on the power utilization unit 101 connected to the performance management unit, generate a switching instruction according to a decision result, and send the switching instruction to the switching unit 104 connected to the performance management unit;
each switching unit 104 is configured to turn on or off the connection between the power consumption unit 101 and the power management unit 103 connected thereto according to the received switching instruction.
