Voltage dynamic adjustment method and device, equipment and medium

Abstract

The invention discloses a method for dynamically adjusting voltage. The method comprises the following steps of electrifying a CPLD (Complex Programmable Logic Device) in response to startup, and controlling a power supply chip to electrify an exchange chip through the CPLD; detecting an AVS value output by the switching chip through the CPLD, and filtering out an invalid AVS value; converting thefiltered AVS value into a register value meeting the standard requirement of a PMBUS, transmitting the register value to a register for controlling an output voltage value in the power supply chip through the PMBUS, and acquiring the output voltage of the power supply chip to the switching chip by the register according to the register value; and the reset signal output to the switching chip being configured to be at a high level to execute voltage outputted to the switching chip after the CPLD controls delay for a preset time. The invention further discloses a device, equipment and a medium.The method is advantaged in that an output voltage of the power supply chip can be controlled by dynamically adjusting the voltage of the core through the CPLD, so power consumption of the switchingchip is reduced.

Description

technical field [0001] The present invention relates to the technical field of hardware monitoring, and more specifically, to a method, device, equipment and medium for dynamically adjusting voltage. Background technique [0002] With the continuous development of network communication, the switch must exist in the network. At present, the bandwidth of the switch chip is getting larger and higher, and the frequency is getting higher and higher, which will bring about the problem of power consumption. Excessive power consumption will affect the smooth operation of the entire switch system. [0003] Regarding how to reduce the power consumption of the switch, some switch chip manufacturers have proposed their own design methods for reducing power consumption, most of which are to reduce the power consumption of the switch chip by reducing the voltage. [0004] At present, some switch manufacturers do not use the dynamic voltage adjustment function of AVS (Adaptive Voltage Sca...

Problems solved by technology

[0005]However, the Core voltage of Broadcom switching chips is different for each chip. If the Core voltage is a lower limit value, the fixed value set by the switch manufacturer is higher than the actual value of the chip. The value is high, and the current required by the switching chip is a fixed value, which will increase the overall power consumption of the switch system virtually; if the fixed value set by the switch manufacturer is higher than the actual value of the chip, it may cause damage to the chip and reduce the power consumption of the switch. service life; and the overall power consumption of the switch system increases, which will increase the pressure on the overall heat dissipation, increasing the noise of the fan, etc.
