Description

Technical Field

[0001] This invention relates to the field of processor technology, and in particular to a power supply system and an artificial intelligence system based on an artificial intelligence processor. Background Technology

[0002] Currently, AI power delivery networks face a fundamental physical contradiction: the "inductor wall" problem. This directly conflicts between the demands for rapid, instantaneous current changes and the stringent stability requirements of the power supply voltage. To balance energy efficiency and performance, processors need to save power under low loads through dynamic voltage regulation, but must also withstand extreme transient current surges—currents can jump by 1000 amperes in just 40 nanoseconds, a rate of change as high as 25 GA / s. At this ultra-fast speed, even tiny parasitic inductances in the circuit traces can create significant resistance, causing the supply voltage to "collapse" before the regulator can respond. This is particularly dangerous for advanced logic circuits operating at only 0.8V: a voltage drop of just 50 millivolts can trigger calculation errors or system failures. The core of this challenge can be attributed to the "capacitor paradox": to buffer these nanosecond-level transient currents, the system needs to deploy a large number of decoupling capacitors; however, these capacitors themselves become a burden on the rapid voltage regulation. Because changing the power rail voltage requires charging and discharging all the capacitors in the network, too many capacitors—even on-chip MIM capacitors or deep-groove capacitors—can introduce significant RC delay, making it impossible for the voltage regulation speed to keep up with the rapid switching of AI workloads.

[0003] Specifically, when an AI processor's digital logic unit experiences a sudden 1000A current surge within 40 nanoseconds, the external DC-DC converter, due to its slow inductor response (typically on the order of microseconds), cannot immediately provide all the required charge. The current gap must be filled in real-time by on-chip capacitors. To keep the voltage drop below 50mV, the on-chip capacitor requirement can reach thousands of microfarads or even higher, significantly increasing chip manufacturing costs. Simultaneously, such large capacitors also prevent rapid voltage regulation, thus limiting the practical effectiveness and energy-saving potential of dynamic voltage regulation. As CMOS dimensions continue to shrink and speeds increase, one current mainstream solution is to use advanced processes to increase the switching frequency of the DC-DC converter, thereby accelerating the inductor's response and suppressing voltage drops. However, high-frequency switching introduces significant switching losses, reducing overall power efficiency. Currently, there is an urgent need for a processor capable of rapidly responding to the workloads of AI processors. Summary of the Invention

[0004] This invention provides a power supply system and an artificial intelligence system based on an artificial intelligence processor. Through the coordinated control of a fast voltage regulator module and a DC-DC converter module, it can achieve rapid dynamic voltage regulation to adapt to the rapid changes in the workload of the artificial intelligence processor.

[0005] In a first aspect, embodiments of the present invention provide a power supply system based on an artificial intelligence processor, the power supply system comprising a first power supply rail, a second power supply rail, a DC-DC conversion module, a fast voltage regulation module, and a control module; The DC-DC conversion module includes multiple DC-DC conversion units, and the fast voltage regulator module includes multiple fast voltage regulator units; Multiple DC-DC conversion units are connected in parallel on the first power supply rail, and the output terminals of the multiple DC-DC conversion units are all connected to the output terminal of the power supply system; Multiple fast voltage regulator units are connected in parallel on the second power supply rail, and the output terminals of the multiple fast voltage regulator units are all connected to the output terminal of the power supply system, and the output terminal of the power supply system is connected to the power input terminal of the artificial intelligence processor. The control module is electrically connected to the DC-DC converter and the fast voltage regulator module respectively. The control module is used to determine the status information of the artificial intelligence processor and switch the DC-DC converter to power the artificial intelligence processor or the fast voltage regulator module to power the artificial intelligence processor according to the status information. The voltage of the first power supply rail is greater than the voltage of the second power supply rail.

[0006] Optionally, the control module is used to detect the total current information output by the fast voltage regulator module, and determine the state information of the artificial intelligence processor based on the total current information. When the rate of change of the total current information is detected to be less than or equal to the transient threshold, the state information of the artificial intelligence processor is determined to be in a voltage regulation working state. When the rate of change of the total current information is detected to be greater than the transient threshold, the state information of the artificial intelligence processor is determined to be in a transient current state.

[0007] Optionally, when the control module determines that the state information of the artificial intelligence processor is a transient current state, it supplies power to the artificial intelligence processor through the fast voltage regulation module and sends a control signal to the DC-DC converter module to increase the output current of the DC-DC converter module until the output current of the DC-DC converter module reaches the set value, and then switches the DC-DC converter module to supply power to the artificial intelligence processor.

[0008] Optionally, when the control module determines that the status information of the artificial intelligence processor is in a regulated working state, it supplies power to the artificial intelligence processor through the DC-DC converter module and controls the fast voltage regulator module to be in a sleep state.

The main voltage regulating unit is electrically connected to the first control unit, and the main voltage regulating unit is used to summarize the total current information of the fast voltage regulating module and send the total current information to the first control unit. During the transient current state, the power supply system supplies power to the artificial intelligence processor through the fast voltage regulation module. At the same time, the first control unit sends a control signal to the DC-DC converter module based on the total current information to increase the output current of the DC-DC converter module until the output current of the DC-DC converter module reaches the set value, and then switches the DC-DC converter module to supply power to the artificial intelligence processor.

[0010] Optionally, the control module further includes a second control unit, wherein both the main voltage regulator unit and the slave voltage regulator unit are electrically connected to the second control unit; The second control unit is used to receive the first current signal sent by the main voltage regulator unit, generate a synchronization signal, and send it to multiple slave voltage regulator units so that the output current of the slave voltage regulator units is consistent with the output current of the main voltage regulator unit.

[0011] Optionally, the plurality of DC-DC conversion units include a master conversion unit and a plurality of slave conversion units. The master conversion unit and the slave conversion units are electrically connected to the first control unit. The first control unit is further configured to receive second current information from the master conversion unit and generate a plurality of current distribution signals according to the second current information and send them to each of the slave conversion units respectively, so as to make the phase of the output current of the plurality of DC-DC conversion units uniform.

[0012] Optionally, each of the DC-DC conversion units includes an inductor; The inductor is connected in series between the output terminal of the DC-DC conversion unit and the output terminal of the power supply system.

[0013] Optionally, the first power supply rail is 3V and the second power supply rail is 1.8V.

[0014] Secondly, embodiments of the present invention also provide an artificial intelligence system, the artificial intelligence system including any of the power supply systems described in the first aspect.

[0015] In the power supply system provided in this embodiment of the invention, multiple DC-DC conversion units are connected in parallel on a first power supply rail, and the output terminals of all DC-DC conversion units are connected to the output terminal of the power supply system. Multiple fast voltage regulator units are connected in parallel on a second power supply rail, and the output terminals of all fast voltage regulator units are connected to the output terminal of the power supply system, which is connected to the power input terminal of the artificial intelligence processor. A control module is electrically connected to both the DC-DC conversion module and the fast voltage regulator module. The control module is used to determine the status information of the artificial intelligence processor and, based on the status information, switches between using the DC-DC conversion module to power the artificial intelligence processor and using the fast voltage regulator module to power the artificial intelligence processor. Thus, through the coordinated control of the fast voltage regulator module and the DC-DC conversion module, rapid dynamic voltage regulation can be achieved to adapt to the rapid changes in the workload of the artificial intelligence processor.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be fully described below with reference to the accompanying drawings in the embodiments of this invention, through specific implementation methods. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.

[0018] Figure 1 This is a schematic diagram of a power supply system based on an artificial intelligence processor provided in an embodiment of the present invention. See also... Figure 1The power supply system includes a first power supply rail 10, a second power supply rail 20, a DC-DC converter module 30, a fast voltage regulator module 40, and a control module 50. The DC-DC converter module 30 includes multiple DC-DC conversion units 310, and the fast voltage regulator module 40 includes multiple fast voltage regulator units 410. The multiple DC-DC conversion units 310 are connected in parallel on the first power supply rail 10, and their outputs are all connected to the power supply system's output terminal OUT. The multiple fast voltage regulator units 410 are connected in parallel on the second power supply rail 20, and their outputs are all connected to the power supply system's output terminal OUT. The power supply system's output terminal OUT is connected to the power input terminal of the artificial intelligence processor. The control module 50 is electrically connected to both the DC-DC converter module 30 and the fast voltage regulator module 40. The control module 50 is used to determine the status information of the artificial intelligence processor and, based on the status information, switches between the DC-DC converter module 30 supplying power to the artificial intelligence processor and the fast voltage regulator module 40 supplying power. The voltage of the first power supply rail 10 is greater than the voltage of the second power supply rail 20.

[0019] For example, such as Figure 1 In the illustrated embodiment, the power supply system includes multiple power supply rails, including a first power supply rail 10 and a second power supply rail 20. The first power supply rail 10 can be the main power supply rail, that is, during the operation of the artificial intelligence processor, the core part of the artificial intelligence processor is powered through the first power supply rail 10. The second power supply rail 20 can be a power supply rail for the non-core circuits of the artificial intelligence processor. In one embodiment, the power supply voltage provided by the first power supply rail 10 can be 3V, and the power supply voltage provided by the second power supply rail 20 can be 1.8V, with the power supply voltage provided by the first power supply rail 10 being greater than that provided by the second power supply rail 20. Based on the above, the embodiment of the present invention sets the DC-DC conversion module 30 to include multiple DC-DC conversion units 310, which are connected in parallel on the first power supply rail 10. The current provided by the first power supply rail 10 is distributed by the multiple DC-DC conversion units 310 in parallel, thereby reducing the power loss caused by the voltage drop generated by the current across the conductor resistance. In addition, the switching frequency of the DC-DC conversion units 310 is set in the tens of MHz range, which is relatively lenient in terms of process implementation, to optimize the conversion efficiency, thereby making the response speed of the DC-DC conversion module 30 in the hundreds of nanosecond range. However, when only the DC-DC conversion module 30 is provided, the response speed of the DC-DC conversion module 30 is still significantly different from the instantaneous change rate of the artificial intelligence processor during operation (e.g., reaching 1000A within 40ns, with a change rate of tens of nanoseconds). Therefore, this embodiment of the invention also provides a fast voltage regulation module 40. Through the coordinated control of the fast voltage regulation module 40 and the DC-DC conversion module 30, fast dynamic voltage regulation is achieved to adapt to the rapid changes in the workload of the artificial intelligence processor.

[0020] Specifically, such as Figure 1 As shown, the fast voltage regulator module 40 includes multiple fast voltage regulator units 410, which can be digital low-dropout regulators. The multiple fast voltage regulator units 410 are connected in parallel on the second power supply rail 20, and the output terminals of all the fast voltage regulator units 410 are connected to the output terminal OUT of the power supply system. The output terminals of all the DC-DC converter units 310 are also connected to the output terminal OUT of the power supply system. The control module 50 is electrically connected to both the DC-DC converter module 30 and the fast voltage regulator module 40. The control module 50 can detect the operating state of the artificial intelligence processor (i.e., whether the load current undergoes extremely rapid transient changes). For example, the operating state of the artificial intelligence processor can include transient current state (the load current undergoes extremely rapid transient changes, such as reaching 1000A within 40ns) and voltage regulation operating state (the load current changes normally and smoothly). When the control module 50 determines that the AI ​​processor is in a transient current state, the DC-DC converter 30, with a response speed of hundreds of nanoseconds (greater than the AI ​​processor's extremely fast transient of 1000A within 40ns), cannot respond in time. However, the fast voltage regulator 40 can immediately detect the extremely fast transient and output a large current within nanoseconds to charge the local capacitor, thereby stabilizing the voltage (for example, if 100 fast voltage regulator units 410 are connected in parallel, each only needs to provide 10A of current under a 1000A transient. Because the fast voltage regulator unit 410 can provide nanosecond-level transient current, it significantly reduces the need for large decoupling capacitors on the power supply rail, thus enabling the entire power supply system to achieve rapid dynamic voltage regulation). In other words, the fast voltage regulator 40 is switched to provide power temporarily to charge the AI ​​processor, thereby reducing the real-time requirements of the AI ​​processor during instantaneous changes. After stabilization, the DC-DC converter 30, with a response speed of hundreds of nanoseconds, is used to supply power. When the control module 50 determines that the AI ​​processor is in a regulated operating state, it directly supplies power through the DC-DC converter module 30. In this way, through the coordinated control of the fast voltage regulator module 40 and the DC-DC converter module 30, rapid dynamic voltage regulation can be achieved to adapt to the rapid changes in the workload of the AI ​​processor.

[0021] It should be noted that the fast voltage regulator module 40 is connected in parallel to the second power supply rail 20, drawing current from it. Although the second power supply rail 20 will experience a voltage drop (up to several hundred millivolts) when current is rapidly drawn, it can tolerate larger voltage fluctuations because it does not directly power the core circuitry of the AI ​​processor. Furthermore, it operates at a fixed voltage, eliminating the need for dynamic voltage adjustment. This design allows the necessary large-capacity decoupling capacitors to be placed on the PCB or package substrate, rather than inside the expensive AI processor chip, thus achieving system-level cost and performance optimization.

[0022] In summary, the power supply system provided in this embodiment of the invention includes multiple DC-DC converters connected in parallel on a first power supply rail, with the output terminals of each DC-DC converter connected to the output terminal of the power supply system. Multiple fast voltage regulators are also connected in parallel on a second power supply rail, with their output terminals connected to the output terminal of the power supply system. The output terminal of the power supply system is connected to the power input terminal of the artificial intelligence processor. A control module is electrically connected to both the DC-DC converter module and the fast voltage regulator module. The control module determines the status information of the artificial intelligence processor and switches between supplying power to the artificial intelligence processor via either the DC-DC converter module or the fast voltage regulator module, based on the status information. Thus, through the coordinated control of the fast voltage regulator module and the DC-DC converter module, rapid dynamic voltage regulation can be achieved to adapt to the rapid changes in the workload of the artificial intelligence processor.

[0023] Optionally, based on the above embodiments, see also... Figure 1 The control module 50 is used to detect the total current information output by the fast voltage regulator module 40, and to determine the state information of the artificial intelligence processor based on the total current information. When the rate of change of the total current information is less than or equal to the transient threshold, the state information of the artificial intelligence processor is determined to be the voltage regulation working state. When the rate of change of the total current information is greater than the transient threshold, the state information of the artificial intelligence processor is determined to be the transient current state.

[0024] For details, please refer to [link / reference]. Figure 1 The fast voltage regulator module 40 can aggregate the total current information of multiple fast voltage regulator units 410. This total current information reflects in real time the sum of current that all parallel fast voltage regulator units 410 are about to draw from the second power supply rail 20 to meet the instantaneous demand of the artificial intelligence processor. In other words, the total current information can inform the control module 50 how much current the workload of the artificial intelligence processor requires. Furthermore, when the control module 50 detects that the rate of change of the total current information is greater than the transient threshold (e.g., reaching 1000A within 40ns), it indicates that the workload of the artificial intelligence processor has experienced an extremely rapid transient change, and the state information of the artificial intelligence processor is determined to be in a transient current state. When the control module 50 detects that the rate of change of the total current information is less than or equal to the transient threshold (e.g., continuously reaching 1000A within a set time), the state information of the artificial intelligence processor is determined to be in a regulated operating state. Thus, using the total current information of the fast voltage regulator module 40 to determine whether the load current of the artificial intelligence processor has experienced an extremely rapid transient change is a simple and efficient method.

[0025] Optionally, based on the above embodiments, see also... Figure 1When the control module 50 determines that the state information of the artificial intelligence processor is a transient current state, the DC-DC converter 30 cannot respond in time. However, the fast voltage regulator 40 can immediately detect the extremely fast transient and output a large current to charge the local capacitor within a nanosecond time, thereby stabilizing the voltage. Then, by first switching the fast voltage regulator 40 to supply power, the power supply can be temporarily provided to charge the processor, thereby reducing the real-time requirements of the artificial intelligence processor when the transient changes occur. At the same time, after receiving the total current signal of the extremely fast transient, the control module 50 sends a control signal to the DC-DC converter 30 to accelerate the increase of the output current of the DC-DC converter 30 until the output current of the DC-DC converter 30 reaches the set value (i.e., meets the power supply requirements). Then, the DC-DC converter 30 is switched to supply power to the artificial intelligence processor, taking over the power supply task of the fast voltage regulator 40. This not only improves the response speed of the DC-DC converter 30, but also reduces the continuous current loss of the fast voltage regulator 40.

[0026] Optionally, when the control module 50 determines that the AI ​​processor's status information indicates a regulated operating state, it supplies power to the AI ​​processor via the DC-DC converter 30 and controls the fast voltage regulator module 40 to enter a sleep state. Specifically, when the AI ​​processor's status information indicates a regulated operating state, the current is continuously supplied by the responsive DC-DC converter 30 through an inductor. At this time, the fast voltage regulator module 40 does not need to undertake the main current supply task, only maintaining an extremely low quiescent current. Therefore, the additional power consumption it brings is negligible, and the overall steady-state efficiency of the power supply system is dominated by the high-efficiency DC-DC converter 30.

[0027] Optionally, based on the above embodiments, Figure 2 This is a detailed structural diagram of a power supply system based on an artificial intelligence processor provided in an embodiment of the present invention. See also... Figure 2 The control module 50 includes a first control unit 510 and multiple fast voltage regulator units 410, including a main voltage regulator unit 411 and multiple slave voltage regulator units 412. The main voltage regulator unit 411 is electrically connected to the first control unit 510 and is used to summarize the total current information of the fast voltage regulator module 40 and send the total current information to the first control unit 510. In the transient current state, the power supply system supplies power to the artificial intelligence processor through the fast voltage regulator module 40. At the same time, the first control unit 510 sends a control signal to the DC-DC converter module 30 according to the total current information to increase the output current of the DC-DC converter module 30 until the output current of the DC-DC converter module 30 reaches the set value, and then switches the DC-DC converter module 30 to supply power to the artificial intelligence processor.

[0028] Specifically, such as Figure 1 and Figure 2As shown, the multiple parallel fast voltage regulator units 410 include a main voltage regulator unit 411 and multiple slave voltage regulator units 412. The output terminals of the main voltage regulator unit 411 and the multiple slave voltage regulator units 412 are all connected to the power supply input terminal of the artificial intelligence processor. Among them, the main voltage regulator unit 411 can summarize the output current of the multiple slave voltage regulator units 412 and its own output current to obtain the total current information of the fast voltage regulator module 40, and send it to the first control unit 510. The first control unit 510 can be a DC-DC converter control unit. When the status information of the artificial intelligence processor is a transient current state, the total current information of the fast voltage regulator module 40 will notify the first control unit 510 that the fast voltage regulator module 40 has already output most of the current. Then, the first control unit 510 will send a boost signal to the DC-DC converter module 30 to accelerate the increase of the inductor current, thereby taking over the power supply task of the fast voltage regulator module 40. After the output current of the DC-DC converter module 30 reaches the set value, the DC-DC converter module 30 will be switched to supply power to the artificial intelligence processor. This improves the response speed of the DC-DC converter module 30 and reduces the continuous current loss of the fast voltage regulator module 40.

[0029] Optional, see below Figure 2 The control module 50 also includes a second control unit 520, with the main voltage regulator unit 411 and the slave voltage regulator unit 412 both electrically connected to the second control unit 520. The second control unit 520 is used to receive a first current signal sent by the main voltage regulator unit 411, generate a synchronization signal, and send it to the multiple slave voltage regulator units 412 so that the output current of the slave voltage regulator units 412 is consistent with the output current of the main voltage regulator unit 411.

[0030] Specifically, such as Figure 2 As shown, the second control unit 520 can be a voltage regulator unit controller. The main voltage regulator unit 411 sends a first current signal to the second control unit 520. The second control unit 520 generates a synchronization signal based on the first current signal and sends the synchronization signal to all the slave voltage regulator units 412 to ensure that the output current of all slave voltage regulator units 412 is synchronized with the output current of the main voltage regulator unit 411 and the amplitude is basically the same, thereby realizing the uniform distribution of transient current among the distributed fast voltage regulator units 410.

[0031] Optional, see below Figure 1 and Figure 2 The multiple DC-DC conversion units 310 include a main conversion unit 311 and multiple slave conversion units 312. Both the main conversion unit 311 and the slave conversion units 312 are electrically connected to the first control unit 510. The first control unit 510 is also used to receive the second current information of the main conversion unit 311 and generate multiple current distribution signals according to the second current information and send them to each slave conversion unit 312 respectively, so that the phase of the output current of the multiple DC-DC conversion units 310 is uniform.

[0032] Specifically, the first control unit 510 is a DC-DC conversion control unit used to control the output of the DC-DC conversion unit 310. After determining the second current information of the main conversion unit 311, the first control unit 510 generates multiple current distribution signals based on the second current information and sends them to each slave conversion unit 312 respectively to evenly distribute the circuit among the multi-phase inductors, thereby maintaining the overall stability of the power supply system. It also adjusts the phase of the multi-phase inductors to ensure phase uniformity, thereby reducing the ripple current at the load end of the artificial intelligence processor and the fast voltage regulator module 40 in the power supply system, reducing overall energy loss, and improving the efficiency of the DC-DC conversion module 30.

[0033] It should be noted that, please continue to refer to Figure 1 and Figure 2 Each DC-DC converter 310 includes an inductor L. The inductor L is connected in series between the output terminal of the DC-DC converter 310 and the output terminal OUT of the power supply system. Specifically, the inductor L is an energy storage element. During the switching cycle of the DC-DC converter 310, it stores energy when the DC-DC converter 310 is turned on and releases energy when it is turned off, thereby converting the intermittent switching current into a continuous and smooth output current, reducing the impact of sudden current changes on the load. Furthermore, when the load current of the AI ​​processor changes rapidly, the inductor current cannot change abruptly. The self-induced electromotive force of the inductor L resists the current change, helping to buffer transient current surges and providing response time for the subsequent fast voltage regulator module 40. Moreover, when multiple DC-DC converters 310 operate in parallel, the inductors L in each DC-DC converter 310 help balance and distribute the current, thereby preventing overload of a single DC-DC converter 310.
