Abstract
The present invention applies to the field of integrated-circuit control, and provides a temperature feedback control system and method for DVFS (Dynamic Voltage Frequency Scaling). In the present invention, a main processor sends a control data packet to a microprocessor according to a received temperature feedback trigger signal, and the microprocessor immediately triggers working of a temperature data acquiring module, and after the temperature data acquiring module acquires real-time temperature data of a chip, executes a temperature feedback algorithm on the real-time temperature data according to the control data packet to output a corresponding performance control parameter, so as to enable a DVFS circuit to adjust a working frequency and a working voltage of the chip, and further enable the chip to implement automatic frequency and voltage adjusting at a low voltage and a low temperature and at a high voltage and a high temperature.
