Adaptive Voltage Scaling (AVS) is a closed-loop dynamic power minimization technique that adjusts the voltage supplied to a computer chip to match the chip's power needs during operation. Many computer chips, especially those in mobile devices or Internet of things devices are constrained by the power available (for example, they are limited to the power stored in a battery) and face varying workloads. In other situations a chip may be constrained by the amount of heat it is allowed to generate. In addition, individual chips can vary in their efficiency due to many factors, including minor differences in manufacturing conditions. AVS allows the voltage supplied to the chip, and therefore its power consumption, to be continuously adjusted to be appropriate to the workload and the parameters of the specific chip. This is accomplished by integrating a device that monitors the performance of the chip (a hardware performance manager) into the chip, which then provides information to a power controller.

The application belongs to the technical field of low power consumption, and particularly relates to a low power consumption design method and device with adaptive voltage regulation. The method comprises the following steps: 1) simulating a key path of an analog-digital circuit, wherein the key path refers to a path with the maximum delay in the digital circuit; 2) generating a test clock signal and a sampling clock signal, and inputting the generated test clock signal into the key path; 3) detecting the output signal of the key path by using the sampling clock signal with the same sampling time and / or different sampling times, and controlling and adjusting the power supply voltage of the digital circuit according to the detection result, so as to determine the minimum power consumption voltage for ensuring the normal operation of the digital circuit. The application uses the key path to represent a complex load, and has simple structure and wide application range. The power supply voltage of the circuit is controlled and adjusted according to the voltage detection result, so that the control precision and the adjustment efficiency are improved, the minimum voltage for ensuring the normal operation of the circuit is determined, and energy saving is achieved.
