Wake-up ensures efficient network switching, so that even if a fatal error occurs on an external network such as the Internet, the internal network of the company can be used normally. This can effectively reduce costs and office space.

Hereinafter, a preferred embodiment of a computer with a network switching function and a network switching method according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention can be applied to various types of computers, such as desktop computers used in a company that independently operates and manages an internal network in a company, apart from an external network such as the Internet.

For example, FIG. 1 illustrates a configuration of an embodiment of a computer equipped with a network switching function according to the present invention. The computer includes a central processing unit (CPU) and a memory controller hub (MCH). ), Video Graphics Array (VGA) card, Peripheral Component Interconnect express (PCle) x 16 card, Ethernet switch, I / O Controller Hub (ICH), and Optical Disc Drive (ODD) Etc. are comprised.

In addition, as shown in Fig. 1, the computer includes a LAN selection unit 10, a memory selection unit 20, an HDD selection unit 30, a network switch input unit 30, and a power switch input unit 40. ) Is configured to include.

On the other hand, the LAN selection unit 10, for example, as shown in Figure 2, LAN Port A (LAN Port A) 100 for the use of the internal network, and LAN port B ( LAN Port B) 101, and a LAN switch 102 for selectively switching the LAN ports.

In addition, the LAN switch 102 performs an interface with an Ethernet switch connected to the input / output controller hub ICH, and also has a microcomputer (or SIO) in the network switch input unit 30 shown in FIG. The LAN port A 100 or the LAN port B 101 is selected according to a selection signal (eg, SEL) output from the.

In addition, as shown in FIG. 3, the memory selection unit 20 includes four dual inline memory modules (DIMMs), for example, DIMM 0 (200) and DIMM 2. 202 is for using an internal network, and DIMM 1 201 and DIMM 3 203 are for using an external network.

Meanwhile, the dual in-line memory module (DIMM) divides and allocates a DIMM slot in half, and is selected by the memory controller hub (MCH). The DIMM includes a plurality of DRAM chips. A memory module mounted on a circuit board and used as a main memory of a computer.

The memory controller hub (MCH) is an integrated circuit that resides on the main board of a computer and controls high speed devices such as CPU, VGA card, PCle x 16 card, and DIMM attached to the computer.

The memory controller hub (MCH) determines whether each port is an input or an output. For example, as shown in FIG. 4, a standard Data Direction Resister port x (DDRx) system is used. Control the memory selection unit 20 by using the clock, data, command and control values defined in the configuration of a standard bus bus. do.

For example, as shown in FIG. 5, a memory controller hub (MCH) serving as a north bridge of one channel may include a demux having 12 input ports and 24 output ports. PI3PCIE2612-A), and two DIMM slots are connected to the demux.

On the other hand, as shown in Figure 6, the memory controller hub (MCH), which serves as a North Bridge of two channels, is connected to a demux having 12 input ports and 24 output ports. Four DIMM slots are connected to the demux.

In addition, the demux is controlled to be switched to a selection signal (for example, SEL) output from a micom in the network switching switch input unit 40, for example, for convenience of layout. For this purpose, it is desirable to be arranged at the bottom layer, and also to have a signal route at the bottom layer.

Meanwhile, as shown in FIG. 7, the input / output controller hub (ICH) serving as a BIOS (BIO) determines whether a DIMM slot is installed by checking a rank through SPD data connected through SMBUS. In this case, since the memory mounted in the internal network and the external network DIMM slots must be recognized separately, the SMB_DATA is switched and managed separately.

As shown in FIG. 8, the micom 401 included in the network switch input unit 40 includes a network switch switching button 400 and a power switch button in the power switch input unit 50. According to the on / off of 500, a selection signal (eg, SEL) for selecting a memory, a LAN port, a hard disk, and the like is output.

In addition, the selection signal SEL is input to the input / output controller hub ICH, and the memory power-out (MEM_PWRO) signal output from the microcomputer 401 is a voltage regulator VR for supplying power to a memory or the like. A high level signal is applied to one terminal of an OR gate provided in front of an enable port EN of a regulator.

In addition, a low level sleep signal SLP_S4 # is applied to the other terminal of the OR gate, for example, when the power saving mode S4 Status is set, so that the low voltage sleep signal SLP_S4 # is applied. In the VR, even if the hibernation mode is set, power is continuously supplied to the memory by the memory power-out (MEM_PWRO) signal of the microcomputer 401.

In addition, the selection signal SEL of the microcomputer 401 is applied to the SATA switch 300 included in the hard disk selection unit 30, as shown in FIG. 9, to connect the SATA port 0 301. Select one of the internal network OS (OS1) stored in the hard disk 1 through, or the external network OS (OS2) stored in the hard disk 2 through the SATA port 1 (302).

The SATA switch 300 may be, for example, a PI2DBS212 chip, which is a differential broadband signal switch, and SATA ports 2 to 6 (303 to 307) may be shared in common.

 On the other hand, the network switching operation by switching the LAN port according to the present invention, the network switching switch button 400 input by the user, is made according to the selection signal (SEL) output from the microcomputer 401, This will be described in detail below.

10 to 12 show an operation flowchart of an embodiment of a network switching method according to the present invention. In a computer equipped with a network switching function between an internal network and an external network, The use of a specific network of either the internal network or the external network may first be set to a default value. In the present invention, it is assumed that the use of the internal network is set first.

On the other hand, when the computer is powered on (S10), for example, SLP_S3 # and SLP_S5 # of the sleep signal SLP of the input / output controller hub ICH shown in FIG. 8 are Low, and the voltage regulator ( VR), VCC_DDR is Low, and SEL, which is the selection signal of the microcomputer 401, is low, and an event occurs in IO_PWRBTN # of the microcomputer 401.

In addition, booting configuration means for using Network 1, which is an external network such as the Internet (S11), for example, SLP_S3 # and SLP_S5 # of the input / output controller hub ICH are high. The VCC_DDR of the voltage regulator VR is high, and the SEL of the microcomputer 401 is low, thereby inducing the Windows application to enter the standby mode (S12).

That is, when the SLP_S5 # goes from low to high, the SLP_S5 # is induced to enter the standby mode for the Windows application to operate. Then, while the power is supplied to the memory, the memory is separated for use of the network 1. (S13).

For example, SLP_S3 # is Low, SLP_S5 # is High, VCC_DDR is High, and SEL is Low. The microcomputer 401 switches SLP_S5 # from Low to High, and VCC_DDR is High. When the SLP_S3 # goes from high to low, the SEL state is changed.

In the state where power is supplied to the memory, a switch is made to a configuration means for using an internal network, Network 0 (S14). For example, SLP_S3 # is Low and SLP_S5 # Is High, VCC_DDR is High, and SEL is Low.

In addition, when the power is supplied to the memory, the system is forcibly reset (S15). For example, SLP_S3 # is Low, SLP_S5 # is High, VCC_DDR is High, and the SEL is High. That is, when a predetermined time elapses after the condition is satisfied, the microcomputer 401 generates an interrupt to the input / output controller hub ICH and forcibly resets it.

When booting to the configuration for using network 0 (S16), for example, SLP_S3 # is High, SLP_S5 # is High, VCC_DDR: High, and SEL is High.

Thereafter, as shown in FIG. 11, when the network switch is input (S18), the network enters the standby mode (S4 Status) of the network 0, as shown in FIG. 11. (S19), the data is safely stored in the memory of network 0, and then the memory is separated (S20).

Subsequently, a series of processes for switching to the configuration of network 1 is performed (S21). If the user inputs a power button to shut down the system while using network 0 (S22), system power of network 0 is performed. After turning off (S23), the power supplied to the memory of network 1 is turned off (S24).

On the other hand, if the user attempts to enter the hibernation mode (S4 Status) while using network 0 (S25), a message indicating that the hibernation mode is not available is displayed (S26).

In addition, as shown in FIG. 12, when the network switch is input (S27) while the Wake-Up is being used (S27) as shown in FIG. After entering the standby mode (S4 Status) (S29), after storing data in the memory of the network 1, the memory is separated (S30).

Then, the switch to the configuration of the network 0 (S31), and then wake up (Network) to use (S32) (S32), if you are using the network 1, the user presses the power button to shut down the system If input (S33), the system power of the network 1 is turned off (S34), and then the power supplied to the memory of the network 0 is turned off (S35).

On the other hand, if the user attempts to enter the hibernate mode (S4 Status) while using the network 1 (S36), a message indicating that the hibernate mode is not available is displayed (S37).

Accordingly, in the computer to which the present invention is applied, the data is stored in the memory of network 0 or network 1 by using the standby mode (S3 Status), and then the memory is separated to switch the internal network and the external network independently. It becomes possible.

In addition, by operating the OS (OS) for the internal network and the external network each independently, even if a fatal failure in the external network such as the Internet, the internal network can be used normally without degradation.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. , Alteration, substitution, addition, or the like.
