Problems solved by technology

[0005] The embodiment of the present invention provides a device and recovery method for realizing the last state of the general server power supply, which is used to solve the problem that in the prior art, the state preservation of the last state of the server power supply of the x86 architecture needs to rely on the RTC battery for power supply. When the situation is exhausted, the last state of the power supply cannot save the state. At the same time, there is a technical problem that depends on the CPU platform and cannot be extended to other general servers.

Embodiment 1

[0029]figure 1 It is a schematic structural diagram of a device for realizing the last state of a universal server power supply in an embodiment of the present invention. Such asfigure 1 As shown, the embodiment of the present invention provides a device for realizing the last state of a universal server power supply, and the device includes:

[0030]Central processing unit 1, said central processing unit 1 includes x86 architecture and arm architecture;

[0031]Power supply 2, said power supply 2 is connected to said central processing unit 1;

[0032]A power management chip 3, the power management chip 3 is connected to the power source 2 and is in communication connection with the central processing unit 1;

[0033]The storage chip 4 is arranged on the periphery of the power management chip 3 and is communicatively connected with the power management chip 3.

[0034]Further, the storage chip 4 is a non-volatile storage chip 4.

[0035]Specifically, last state literally means the last state, and he...

Embodiment 2

[0037]The embodiment of the present invention also provides a recovery method for realizing the 2last state of the universal server power supply, such asfigure 2 As shown, the method includes:

[0038]Step 110: Obtain the operating state of the central processing unit 1, where the operating state includes a power-on state and a power-off state;

[0039]Step 120: According to the operating status, the central processing unit 1 sends a status indication signal to the power management chip 3;

[0040]Step 130: After receiving the state indication signal, the power management chip 3 rewrites the last state state through the access interface of the storage chip 4;

[0041]Step 140: When the power supply 2 is unexpectedly powered down and recovered, the power management chip 3 reads the laststate state;

[0042]Step 150: According to the read last state, the power management chip 3 controls the on-off state of the power source 2, where the on-off state of the power source 2 includes on and off;

[0043]Ste...

Abstract

The invention provides a device for realizing the last state of a general server power supply and a recovery method. The device comprises a central processing unit, a power supply, a power supply management chip and a storage chip, wherein the central processing unit comprises an x86 architecture and an arm architecture; the power supply is connected with the central processing unit; the power supply management chip is connected with the power supply and is in communication connection with the central processing unit; and the storage chip is arranged at the periphery of the power supply management chip and is in communication connection with the power supply management chip. By additionally arranging a nonvolatile storage chip to the periphery of the power supply management chip, the device solves the state saving problem of the last state of all platform serves without depending on an RTC battery, and the technical effects of higher reliability and higher adaptability are achieved.

Description

Technical field[0001]The present invention relates to the technical field of server power supply last state, and in particular to a device and recovery method for realizing the last state of a universal server power supply.Background technique[0002]The current general-purpose server is divided into two main types based on x86 architecture and based on arm architecture. For servers based on the x86 architecture, in order to save the last state of the server power supply, a cache powered by the RTC battery on the motherboard is integrated in the x86 CPU. When the AC power input of the server disappears, the cache inside the CPU can pass The RTC button battery on the motherboard can still work normally, and the contents of the last state register on the cache will not be lost. In this way, when the AC power supply of the whole machine is restored, the power control chip on the motherboard can read the last state register on the CPU cache to determine whether to directly power on the se...
