Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a voltage adaptive adjustment method for an integrated circuit, and fig. 1 is a flowchart of the voltage adaptive adjustment method for the integrated circuit provided in the embodiment of the present invention, and referring to fig. 1, the voltage adaptive adjustment method for the integrated circuit includes:
and S110, pre-configuring the expected working frequency and working voltage of the current running period of the integrated circuit and controlling the integrated circuit to run after the maximum current threshold allowed under the expected working frequency and working voltage.
Specifically, the voltage adaptation of the integrated circuit may operate according to a fixed period. And setting the expected working frequency and working voltage of the current running period and the maximum current threshold allowed under the expected working frequency and working voltage in the initial stage of each period, and controlling the running of the integrated circuit at the expected working frequency and working voltage in the running process of each period.
And S120, regulating and controlling the working frequency of the integrated circuit based on the size relation between the actual working current of the integrated circuit and the pre-configured maximum current threshold value in the running process.
Specifically, after the integrated circuit is controlled to operate at the expected operating frequency and the operating voltage, because the integrated circuit is under the action of threshold protection functions such as current and voltage, when the actual operating current exceeds a safety threshold, that is, the maximum current threshold allowed under the expected operating frequency and the operating voltage, a chip in the integrated circuit can generate fast frequency reduction, so that the stability of the operating state of the whole integrated circuit is ensured in a frequency reduction mode. Therefore, the actual operating frequency during the operating cycle may be less than or equal to the expected operating frequency preconfigured at the initial stage of the operating cycle.
And S130, detecting the actual working frequency of the integrated circuit when the current operation period is finished.
And S140, adaptively adjusting the working voltage pre-configured for the next operating period of the integrated circuit according to the difference value between the expected working frequency and the actual working frequency.
Specifically, when the operation cycle is finished, the actual operating frequency of the current operation cycle is detected. And comparing the difference between the actual working frequency and the expected working frequency pre-configured at the initial stage of the current operating period, and determining the working voltage of the integrated circuit in the next operating period according to the difference result so as to adjust the voltage frequency configuration of the next operating period. That is, each frequency corresponds to a plurality of voltages, and the chip in the integrated circuit can adjust the operating voltage according to the actual operating condition. Fig. 2 is a graph of a frequency-voltage correspondence relationship according to an embodiment of the present invention, and referring to fig. 2, a single voltage-frequency curve L of a DVFS may be converted into a plurality of voltage-frequency curves, such that each frequency corresponds to an adaptive voltage adjustment interval W. After a corresponding voltage frequency working interval is determined according to a design specification frame of initial hardware, a chip in the integrated circuit can self-adaptively adjust the relation between the voltage and the frequency of the chip according to the actual working condition to obtain a proper voltage frequency relation under different working conditions, so that the working performance and the energy efficiency ratio of the circuit are improved. The self-adaptive voltage regulation in a short period is realized, and the problem that the optimal energy efficiency ratio is obtained under the condition of no communication is solved.
In the prior art, the voltage corresponding to each frequency is a fixed value, that is, the chips in the integrated circuit operate according to a voltage frequency curve. To ensure that a given voltage runs through all models, the voltage setting for each frequency would be relatively large. However, during the operation of a chip in an integrated circuit at a frequency, the actually required voltage may be lower than the set voltage, which reduces the energy efficiency ratio of the product.
In the voltage adaptive adjustment method of the integrated circuit provided by the embodiment of the invention, the whole adaptive voltage adjustment is operated in a fixed period mode, and the frequency, the voltage and the maximum current allowed under the frequency voltage are set at the initial stage of each period. The circuit is continuously operated in the period process, and under the action of threshold protection functions of current, voltage and the like, when the current or the voltage exceeds a safety threshold, the frequency is quickly reduced to ensure the normal work of the whole circuit, so that the actual working frequency is less than or equal to the initial preset frequency of the period. And when the period is finished, detecting the actual working frequency, comparing the difference with the expected working frequency of the initial period configuration, and determining the voltage frequency configuration of the next working period according to the difference result. The single voltage frequency curve of the DVFS is converted into a section corresponding to the voltage frequency, a chip in the integrated circuit can self-adaptively adjust the relation between the voltage and the frequency according to the actual working condition, and the most appropriate voltage frequency configuration under each working condition is obtained, so that the working performance and the energy efficiency ratio of the circuit are improved.
Fig. 3 is a flowchart of another voltage adaptive adjustment method for an integrated circuit according to an embodiment of the present invention, and referring to fig. 3, the voltage adaptive adjustment method for an integrated circuit includes:
s210, determining the expected working frequency of the integrated circuit; obtaining a working voltage corresponding to the expected working frequency from a voltage-frequency relation storage table; in the voltage-frequency relationship storage table, each working frequency corresponds to a plurality of working voltages.
And S220, determining the maximum current threshold of the integrated circuit according to the expected working frequency and the acquired working voltage.
And S230, pre-configuring the determined expected operating frequency, the determined operating voltage and the maximum current threshold value as the expected operating frequency, the determined operating voltage and the maximum current threshold value allowed under the expected operating frequency and the determined operating voltage of the integrated circuit in the current operating period.
Specifically, the pre-configuring the expected operating frequency, the operating voltage and the maximum current threshold allowed at the expected operating frequency and the operating voltage of the integrated circuit further includes: determining an expected operating frequency of the integrated circuit; acquiring a working voltage corresponding to the expected working frequency from a voltage-frequency relation storage table; in the voltage-frequency relationship storage table, each working frequency corresponds to a plurality of working voltages.
In the early product definition stage, a plurality of frequency-voltage corresponding relation combinations with energy efficiency ratios higher than a preset value are debugged according to different application scenes of the integrated circuit; and storing the determined multiple sets of frequency-voltage corresponding relation combinations in a frequency-voltage mapping table. That is, a plurality of frequency and voltage lattices are added to the DVFS scheme corresponding to the existing single frequency-voltage curve, and the specific number is not limited. In the actual operation process, according to the expected working frequency of the integrated circuit, matching a working voltage corresponding to the expected working frequency from the frequency-voltage mapping table. The different voltages for each frequency determine the maximum allowable operating current, and the maximum current threshold of the integrated circuit may be determined based on the desired operating frequency and the obtained operating voltage.
And at the initial stage of the current operation period, pre-configuring the determined expected operating frequency, operating voltage and maximum current threshold value as the expected operating frequency, operating voltage and maximum current threshold value allowed under the expected operating frequency and operating voltage of the current operation period of the integrated circuit. The working voltage of the current operation period is the working voltage determined according to the operation condition of the previous operation period. When the last operation cycle is finished, if the detected actual operating frequency of the cycle is lower than the expected operating frequency of the last operation cycle, it indicates that the actual operating current of the integrated circuit exceeds the maximum current threshold value preconfigured in the last operation cycle when the integrated circuit operates according to the operating voltage preconfigured in the last operation cycle, so that the integrated circuit has a condition of fast frequency reduction. I.e. more current margin is needed in the current operating situation, the setting of the operating voltage is increased to relax the maximum operating current while increasing the setting of the maximum current threshold when configuring the operating parameters for the current operating cycle. When the actual working frequency is detected to be equal to the expected working frequency, the working current actually generated in the previous operation period is lower than the preset maximum current threshold, and a space for tightening the working voltage exists, so that the working voltage and the maximum current threshold are reduced when the operation parameters are configured in the current operation period.
S240, controlling the integrated circuit to operate according to the expected operating frequency and the preset operating voltage, and regulating and controlling the operating frequency of the integrated circuit based on the size relation between the actual operating current of the integrated circuit and the preset maximum current threshold value in the operating process.
Optionally, the adjusting and controlling the operating frequency of the integrated circuit based on the magnitude relationship between the actual operating current of the integrated circuit and the preconfigured maximum current threshold in the operating process includes: controlling the integrated circuit to operate according to the expected operating frequency and the preconfigured operating voltage, and monitoring whether the operating voltage of the integrated circuit exceeds a maximum operating current threshold value or not in the operating process; if the voltage exceeds the preset value, controlling the integrated circuit to reduce the working frequency; if not, the integrated circuit is controlled to maintain the expected operating frequency to operate.
And S250, detecting the actual working frequency of the integrated circuit when the current operation cycle is finished.
And S260, judging the size relation between the actual working frequency and the expected working frequency.
S270, if the detected actual working frequency is smaller than the expected working frequency, raising the working voltage preconfigured in the next operating period, and increasing the preconfigured maximum working current threshold; if the detected actual operating frequency is equal to the expected operating frequency, the preconfigured operating voltage for the next operating cycle is decreased and the preconfigured maximum operating current threshold is decreased.
Specifically, when the current operation cycle is finished, the actual operating frequency of the integrated circuit is detected, and whether the preset maximum current and the preset operating voltage in the current operation cycle meet the current working scene is determined by comparing the actual operating frequency with the expected operating frequency. When the detected frequency in the period is lower than the expected frequency, the current situation needs more current margin, so that the working voltage can be increased in the next operation period, and the maximum working current is widened, namely the working voltage is increased in the initial stage of the next operation period and the setting of the maximum current threshold value is increased. And when the actual working frequency is detected to be equal to the expected working frequency, the working current actually generated in the current working situation is lower than the preset maximum current threshold, and a space for tightening the working voltage is provided, so that the working voltage and the maximum working current threshold can be adjusted downwards in the next operating period. I.e. the setting of the maximum current threshold and the reduction of the operating voltage in the initial phase of the next operating cycle. By continuously adjusting the voltage increasing and decreasing mode, the voltage is dynamically adjusted by combining the actual working scene, and the optimal performance output is obtained, so that the working performance and the energy efficiency ratio of the integrated circuit are improved.
When the actual working frequency is detected to be lower than the expected working frequency and the working voltage pre-configured in the next operation period is raised, acquiring a voltage value which corresponds to the expected working frequency and is higher than the working voltage in the current operation period from the voltage-frequency relation storage table; and pre-configuring the acquired voltage value which corresponds to the expected working frequency and is greater than the working voltage in the current operating period as the working voltage in the next operating period.
If the actual working frequency is detected to be equal to the expected working frequency, and the working voltage pre-configured in the next operation period is reduced, acquiring a voltage value which corresponds to the expected working frequency and is smaller than the working voltage in the current operation period from the voltage-frequency relation storage table; and pre-configuring the acquired voltage value which corresponds to the expected working frequency and is less than the working voltage in the current operation period as the working voltage in the next operation period.
In the voltage adaptive adjustment method for the integrated circuit provided by the embodiment of the invention, a plurality of frequency-voltage corresponding relation combinations with energy efficiency ratios higher than a preset value are debugged according to different application scenes of the integrated circuit in an early product definition stage and are stored in a frequency-voltage mapping table. During operation, an operating voltage corresponding to the expected operating frequency is matched from the frequency-to-voltage mapping table according to the expected operating frequency of the integrated circuit. And in an actual working scene, whether the preset maximum current and working voltage in the current operation period meet the current working scene is judged by comparing the actual working frequency with the expected working frequency. By continuously adjusting the voltage increasing and decreasing mode, the voltage is dynamically adjusted by combining with an actual working scene, so that the optimal performance output is obtained, and the working performance and the energy efficiency ratio of the integrated circuit are improved.
Optionally, the voltage adaptive adjustment method of the integrated circuit further includes: and detecting abnormal operation information in the operation process of the integrated circuit, and updating the voltage frequency storage table according to the abnormal operation information. The fault tolerance of the boundary circuit is improved, the frequency voltage storage table of the DVFS is diagnosed and adjusted according to the abnormal information, and the adaptive adjustment along with the working life can be realized aiming at long-term and aging working scenes.
Wherein, updating the voltage frequency memory table according to the abnormal operation information comprises: judging whether the integrated circuit can repair the abnormality through voltage regulation or not according to the operation abnormality information; if yes, determining a voltage abnormity type, and adjusting the working voltage corresponding to each working frequency in the voltage frequency storage table according to the voltage abnormity type so as to realize self-adaptive adjustment of the voltage frequency storage table aiming at long-term and aging working scenes; the voltage abnormity type comprises a higher voltage type and a lower voltage type.
