Abstract

The invention relates to a self-adaptive voltage regulation SoC system and a control method. The system comprises a power circuit and an energy-saving optimization circuit which are connected with each other; the power supply circuit is connected with a battery power supply unit and a power supply unit; the power supply circuit is connected with internal equipment of the SoC system and provides power supply voltage; the power supply circuit is used for supplying power by adopting the battery power supply unit or the power supply unit so as to output power supply voltage; the energy-saving optimization circuit is used for acquiring state data of the SoC system and adjusting the power supply voltage and the working frequency of the power supply circuit according to the state data; and the state data comprises frequency information, voltage information and temperature information. According to the invention, through design of the system power supply architecture, the voltage is rapidly adjusted, the time sequence margin is further reduced, and deeper optimization of the power consumption is realized.

Description

technical field [0001] The present application relates to the technical field of low power consumption design, in particular to an adaptive voltage regulation SoC system and a control method. Background technique [0002] With the process feature size of integrated circuits getting smaller and smaller, and its operating frequency is increasing, chip design is facing more and more challenges, including antenna effect, power / ground network voltage drop, timing closure, power consumption And other issues, especially the challenge of power consumption is particularly severe. On the one hand, gradually increasing application requirements such as 3D (threedimensional, 3D for short) games, Internet of Things devices, etc., have more and more requirements on power consumption; , Voltage, Temperature, referred to as PVT) conditions and working under different aging degrees will have a corresponding impact on the actual working conditions of the chip. [0003] In actual application ...
