One piece in chipset in two pieces of monster chips, be usually used to processing high speed signal, for example, processing processor (CPU) with it is interior
It deposits (Dynamic Random Access Memory, DRAM), accelerated graphics interface (Accelerated Graphic Ports,
) or universal serial bus (Peripheral Component Interconnect Express, PCI Express) and south bridge core AGP
Communication between piece (South Bridge).And other one piece of monster chip is South Bridge chip A3 (South Bridge),
South Bridge chip A3 is responsible for the communication between I/O buses, and processing speed is relatively slow, such as pci bus, general serial center line
(Universal Serial Bus, USB), local area network bus (Local Area Network, LAN), hard-disk interface technology
(Advanced Technology Attachment, ATA), Serial Advanced Technology Attachment (Serial Advanced
Technology Attachment, SATA), Audio Controller, keyboard controller, real-time clock controller, advanced power management
Deng.South Bridge chip A3 is connected by certain way with north bridge, and north bridge chips A2 is connected directly with processor A1.Base on mainboard
This I/O chip A4 (Basic Input Output System, BIOS) is connected to South Bridge chip A3 by certain bus
On.Basic input output system is the program on one group of chip being cured in computer on mainboard, its in store calculating
Self-check program and system self-triggered program after the programs of the most important basic input and output of machine, system set-up information, booting, master
It is to provide the bottom, most direct hardware setting and control for computer to want function, can also be arranged using BIOS setup program
Except the system failure or diagnostic system problem, traditional BIOS chips be read-only memory (Read-Only Memory, ROM) or
Person's flash memory (Flash) is made.Traditional mainboard framework is also connected with external internal storage A5 (such as by ATA or SATA
Connect system disk), and a network interface A6 is connected by local area network bus (LAN) etc..
In the prior art, (such as Fig. 2 when multiple computer systems with above structure are connected in a LAN B
It is shown), mutual access should be able to be realized when sharing functionality is opened between each computer system.Such as computer system B1
The internal storage in computer system B2 and computer system B3 is accessed, and realizes mutual data-transformation facility.Together
Sample, computer system B2 and computer system B1 are also able to access that the internal storage of other computer systems B1.But work as
Its internal storage can not just be accessed by the computer of other in LAN when some computer system is closed.Such as work as computer
When system B1 is closed, computer system B2 and computer system B3 can not just obtain the internal storage in computer system B1
Information can not communicate.Assuming that computer system B1 is not used for a long time, and computer system B2 and computer system B3
The data of internal storage in computer system B1 are accessed at any time, then must just keep computer system B1 to open, in this way
Unnecessary power wastage is resulted in.
On the other hand, in traditional computer system, the high performance processor chips of generally use as processing core, and
High-performance processor chip on the market is usually monopolized several in major company's hand of most advanced manufacturing technology, therefore one
As the processor chips purchased, the executable instruction of inside structure and internal preset is not known to user, this leads
Cause the risk for increasing " safe back door " wherein very big.This kind of " safe back door " can't be found in application usually,
Only when some special external commands activate " safe back door ", the computer system being currently running can just be damaged,
Or in user without stealing privacy information etc. when discovering.
Chinese patent (CN101923382A) discloses a kind of power-economizing method and computer system of computer system.It is described
Method includes：Monitor the switching of active window in operating system；It is inactive monitoring first window by active window and being switched to

Whether data or instruction are safe, and further, in preferred embodiment of the invention, unsafe data may include with ill
The data of poison or trojan horse program, unsafe instruction can be instruction of the malicious instructions such as control system from shutdown, above-mentioned number
According to or instruction energy-saving computer internal system can be sent to by network interface A6 by external network, can also be by processor core
Piece A1 is called from internal storage A5.Therefore, data or the instruction of processor chips A1 are sent to when detection unit A8 is detected
With safety issue, then these data or instruction are intercepted, to ensure the safe to use of energy-saving computer system.
In the preferred embodiment of the present invention, above-mentioned detection unit can also be integrated in (not shown) in South Bridge chip, with
It saves on mainboard and has used area.
In the preferred embodiment of the present invention, above-mentioned detection unit A8 is also connected with mode switching unit A7, and pattern conversion is single
Energy-saving computer system is arranged under a detection working condition by first A7, at this time energy-saving computer system be in main work
It is equally worked normally under state, difference is that detection unit A8 is opened and started the data that capture is sent to processor chips A1
Or instruction, and intercept and be detected as unsafe data or instruction.
The present invention preferred embodiment in, due to the operating status of energy-saving computer system should be it is stable, cannot
Its operating status is arbitrarily changed, therefore in order to provide above-mentioned conversion instruction safely, increases by one in above-mentioned energy-saving computer system
A security input unit A9, connection mode converting unit A7.One of the effect of security input unit A9 is defeated for user
Enter above-mentioned conversion instruction, the two of effect is to provide security authentication services when user inputs, specifically for example：Safety input is single
First A9 includes an input module (not shown) and the authentication module (not shown) that is connect with above-mentioned input module.Work as user
When needing to input corresponding conversion instruction, the authentication for first passing through authentication module is needed, side obtains input qualification, such as passes through
The authentication of user name password or fingerprint authentication input corresponding conversion instruction etc. to distinguish whether user is qualified.
Further include an encryption/decryption module C17 in basic information unit C1 in the preferred embodiment of the present invention, connection is micro-
Processing module C13, the data for being received to micro treatment module C13 are decrypted, and are sent to micro treatment module C13
Data be encrypted, to improve the safety of data processing and interactive communication.
In the preferred embodiment of the present invention, due to can equally preset some executable instructions in processor chips A1,
And due to that can not know the inside structure of high-performance processor chip, we, which can not can know that, defaults in therein can perform
The type of instruction, and whether these executable instructions that have no way of finding out about it are safe.Therefore, further include in above-mentioned energy-saving computer system
One instruction screen unit A10, be equally connected between South Bridge chip A3 and network interface A6 and South Bridge chip A3 with it is interior
Between portion memory A5, include for obtaining the external addressing request for being sent to processor chips A1, and by the addressing request
Storage address information is matched with the above-mentioned suspicious storage address information being set, if successful match, shows to seek at this time
Location request requires processor chips A1 addressing corresponding to the suspicious executable instruction of suspicious storage address information, and instruction at this time is shielded
It covers unit A10 and intercepts the addressing request；The addressing request on the contrary, instruction screen unit A10 lets pass.
Further, in preferred embodiment of the invention, the executable instruction in processor chips A1 is enumerated
The reverse engineering of formula is analyzed to distinguish suspicious or believable executable instruction, such as the user hand according to processor chips A1
Whether volume, the handling result for analyzing the processor chips A1 outputs after reverse engineering is analyzed meet regulation.In user's manual
