The application discloses a dynamic voltage regulation and power balance control method and system in an integrated circuit, and particularly relates to the technical field of integrated circuit power management, which measures the timing margin, load change slope and voltage undershoot amplitude of a key path in real time, calculates a timing robustness quantitative value, calculates a leading compensation pulse and sends the same before load jumping, dynamically switches PID coefficients to suppress nonlinear oscillation, stretches a clock or freezes a pipeline when the timing robustness quantitative value is lower than a first threshold value, inserts idle instructions to cut off positive feedback when the product of a current change rate and a temperature gradient is higher than a second threshold value, decouples and isolates a calculation core from peripheral logic, and calibrates the first and second threshold values, so that the application suppresses voltage transients through the leading compensation pulse, reduces timing violation risks, blocks metastable state propagation and positive feedback cycles through clock stretching or pipeline freezing and forced idle instructions, and improves adaptive capacity through voltage domain decoupling and isolation and stable state feedback calibration of threshold values.

Implementations are disclosed for a power switching regulator defined to be used for power harvesting but is instead configured to include an additional power rail. A switching regulator includes a first contact defined as a first power input to the switching regulator (with the first contact coupled to a first power source), a second contact defined as a second power input to the switching regulator (with the second contact defined to be coupled to a harvester), and a third contact whose output is defined as a storage voltage for harvesting. Instead of the third contact being used for outputting a storage voltage for harvesting, the third contact is coupled to a voltage (VSTORE) power rail for providing power (that may be configurable) to one or more electronic components of the electronic device (such as a CPU to perform dynamic voltage scaling or by a power amplifier sensitive to power efficiency).

This invention discloses a power supply system and an artificial intelligence system based on an artificial intelligence processor. In the power supply system, multiple DC-DC converters are connected in parallel on a first power supply rail, and the outputs of these DC-DC converters are all connected to the output of the power supply system. Multiple fast voltage regulators are connected in parallel on a second power supply rail, and their outputs are also connected to the output of the power supply system. The output of the power supply system is connected to the power input 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 this 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.
