[0036] Please refer to Figure 5 A preferred embodiment of the chip power supply adjustment method of the present invention includes the following steps:
[0037] Step S1, the PLL circuit 50 judges whether the CPU 40 enters the overclocking mode, and when the CPU 40 enters the overclocking mode, enters step S2; when the CPU 40 does not enter the overclocking mode, continues to judge whether the CPU 40 enters the overclocking mode .
[0038]In step S2, the phase-locked loop circuit 50 transmits a trigger signal including communication frequency information corresponding to the operating frequency of the CPU 40 at this time.
[0039] Step S3, the MCU 60 correspondingly adjusts the clock frequency of the MCU 60 itself according to the frequency information included in the trigger signal.
[0040] Step S4, the MCU 60 receives the data information transmitted by the CPU 40, and analyzes the data information to obtain corresponding instructions.
[0041] Step S5, the MCU 60 trans...

The invention relates to a chip power supply regulating system which comprises a frequency tracking circuit, a microprocessor and a voltage regulating module, wherein the frequency tracking circuit is used for outputting a trigger signal containing the information of the communication frequency corresponding to a working frequency of a chip when the chip enters into an over-frequency mode; the microprocessor is used for receiving the trigger signal outputted by the frequency tracking circuit; when the trigger signal is received by the microprocessor, the own clock frequency is correspondingly regulated by the microprocessor according to the information of the communication frequency contained in the trigger signal; the communication data transmitted by the chip is analyzed by the microprocessor, so that a corresponding control command is acquired; the microprocessor is also used for outputting the control command; the voltage regulating module comprises a PWM (Pulse Width Modulation) controller; the PWM controller is used for receiving the control command outputted by the microprocessor and outputting a corresponding voltage to the chip according to the control command. The chip power supply regulating system provided by the invention can ensure the smooth communication of the chip working in the over-frequency mode. The invention also provides a chip power supply regulating method.
Description
technical field [0001] The invention relates to a chip power supply adjustment system and method. Background technique [0002] The existing CPU (Central Processing Unit, central processing unit) provides working voltage through a VRM (Voltage Regulator Module, voltage regulation module). Such as figure 1 As shown, the CPU 10 communicates with the VRM 20 through a PMBus (Power Manager Bus), wherein the PMBus is composed of a clock signal line SCL, a data signal line SDA and a prompt signal line ALTER. The communication frequency of VRM 20 and CPU 10 must be the same. For example, when the operating frequency of CPU 10 is 100 MHz (rated frequency), the communication frequency of CPU 10 is 25 MHz, that is, the communication frequency of VRM 20 must also be 25 MHz at this time. However, in some cases (for example, when the CPU 10 is overclocked), it is possible that the communication frequency between the VRM 20 and the CPU 10 is not consistent, so that the CPU 10 cannot comm...
