Abstract

The invention provides a dynamic voltage frequency regulation system and a method, belonging to the technical field of integrated circuit design. The dynamic voltage frequency regulation system comprises an information monitoring module, a voltage frequency prediction module and a power consumption management module. The information monitoring module collects the real-time state information of theintegrated circuit, the voltage frequency prediction module predicts the working voltage and the clock frequency. The power management module adjusts the value of the power supply voltage and the clock frequency at the next time of the system by configuring a register, and provides the value to the hardware module. The hardware module comprises a processor, a main memory and a communication interface. The power management module adjusts the value of the power supply voltage and the clock frequency at the next time. The dynamic voltage frequency regulation system and method of the invention can predict and regulate the working voltage and clock frequency of the integrated circuit at the next time in real time based on the collected historical state information. Compared with the parameterregulation method such as the clock and the voltage at the existing software level, the feedback is more timely and the power consumption is reduced more greatly.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to a dynamic voltage frequency adjustment system and method. Background technique [0002] Dynamic voltage frequency scaling (Dynamic Voltage Frequency Scaling, DVFS) technology was first seen in the research of computer system architecture. With the expansion of SoC design scale, it was introduced due to the demand for low power consumption design. DVFS technology realizes the dynamic adjustment of chip working voltage and frequency according to the load information monitored by the chip in real time. On the premise of ensuring the system performance requirements, it realizes lower voltage and frequency requirements and reduces waste of power consumption. [0003] The current DVFS technology is mostly based on the preset lookup table mapping information, or the preset upper and lower limit information of the fixed threshold, to judge the working voltage and freque...
