Deng, or, the system power supply stage of Intel (Intel) company defined: S0 start-up period, S1 to S3 sleep stage, S4 dormant stage and S5 dwell period ... Deng.
In the present embodiment, above-mentioned each power supply stage is a corresponding read mode for the driving data of external daughter board 120 all respectively.The read mode of indication herein, can comprise continuous read mode, fixed interval read mode, single read mode or stop read mode.The power supply timing unit 220 of Fig. 2 utilize power supply stage list 225 with according to each power supply stage (such as, S3 ~ S5 that list 225 indicates) distinguish corresponding respective reading flag, and each reading flag uses the code stored corresponding to above-mentioned read mode.For example, at this, continuous read mode, fixed interval read mode, single read mode and stopping read mode being sequentially set as code C1, C2, C3 and C4.The continuous read mode of S3 sleep stage and S4 dormant stage corresponding code C1, and the stopping read mode of the corresponding code C4 of S5 dwell period.
Displacement busbar unit 230 is coupled to power supply timing unit 220, its reading enable signal RD_EN sent according to power supply timing unit 220 and carry out the reading of external daughter board 120 driving data.External daughter board 120 is connected to displacement busbar unit 220 by bus-bar 130.Have storage device in the middle of external daughter board 120 to store the driving data of itself, driving data kind herein illustrates in above-described embodiment, does not repeat them here.
In view of this, power supply timing unit 220 is after computer installation 200 starts, just the power supply stage that computer installation 200 is current can be judged, and then select corresponding read mode, and control according to corresponding read mode the busbar unit 230 that is shifted, use and detect and read the driving data of external daughter board 120, allow the South Bridge chip 152 in motherboard 210 and Basic Input or Output System (BIOS) 160 be able to according to driving data to intercom with external daughter board 120 phase.Baseboard management controller 170 also immediately can obtain and monitor the relevent information of external daughter board 120.
The thin portion framework of power supply timing unit 220 is described in detail in detail at this, and is illustrated the method for detecting of external daughter board, Fig. 3 is the process flow diagram of the method for detecting that external daughter board is described according to one embodiment of the invention.Displacement busbar unit 230 comprises digital independent control module 240, data read signal generation module 250 and Data buffer 260.In the present embodiment, displacement busbar unit 230 also comprises output switch 280, preset data memory module 270 and temporary storage location 290.Digital independent control module 240 is coupled to data read signal generation module 250, Data buffer 260 and output switch 280.The first input end of output switch 280 is coupled to Data buffer 260, uses the driving data receiving external daughter board 120.Preset data memory module 270 is coupled to the second input end of output switch 280, and it is in order to store a preset data.Temporary storage location 290 is coupled to the output terminal of output switch 280.
Referring to Fig. 2 and Fig. 3, in step S310, power supply timing unit 220 performs power supply sequential with sequential start to be continued to provide the power supply in computer installation 200 needed for each element, to maintain the running of computer installation 200.In step S320, power supply timing unit 220 judges the power supply stage that computer installation 200 is current, use by select in power supply stage list 225 corresponding read mode one of them, and control according to by the read mode selected the busbar unit 230 that is shifted, to detect and to read the driving data of external daughter board 120.
In the present embodiment, if when selecting continuous read mode or the fixed interval read mode of code C1 or C2, then enter step S330, power supply timing unit 220 sends reading enable signal RD_EN continuously or every a fixed interval, thus control displacement busbar unit 230 to read continuously or to read the driving data in external daughter board 120 with the set time, and driving data is stored in temporary storage location 290.
Similarly, if when selecting the single read mode of code C3, then enter step S340, power supply timing unit 220 sends and once reads enable signal RD_EN, use and control displacement busbar unit 230 single and read driving data in external daughter board 120, and driving data is stored in temporary storage location 290.If when selecting the stopping read mode of code C4, then enter step S350, power supply timing unit 220 stops sending and reads enable signal RD_EN, to stop reading the driving data in external daughter board 120, and to maintain in temporary storage location 290 previously stored in driving data be unlikely lost to make it.By this, in step S360, motherboard 210 just can look for corresponding driver according to the driving data in temporary storage location 290, and comes according to this to intercom with external daughter board 120 phase.
Illustrate that displacement busbar unit 230 reads the detailed process of driving data in external daughter board 120 at every turn at this.Fig. 4 illustrates each flow chart of steps reading driving data in external daughter board according to one embodiment of the invention.Referring to Fig. 2 and Fig. 4, in step S410, digital independent control module 240 judges whether to receive and reads enable signal RD_EN.When digital independent control module 240 receive reading enable signal RD_EN that power supply timing unit 220 transmits read to carry out single time, just step S410 is entered, what digital independent control module 240 judged external daughter board 120 and motherboard 210 couples relation, that is, whether digital independent control module 240 utilization couples signal PS and really couples both confirming, uses control output switch 280 and selects the driving data of the preset data in preset data memory module 270 or external daughter board 120 to be stored in temporary storage location 290.
In other words, when the words that external daughter board 120 does not couple with motherboard 210, just do not need to read the driving data in external daughter board 120, therefore step S430 can be entered by step S420, digital independent control module 240 directly controls output switch 280 to be stored in temporary storage location 290 by preset data used when mutually not coupling, use replacement driving data, the detecting of external daughter board can be completed.
On the other hand, when external daughter board 120 couples mutually with motherboard 210 time, just enter step S440 by step S420, displacement busbar unit 230 just starts the driving data reading external daughter board 120.In detail, digital independent control module 240 control data in displacement busbar unit 230 reads signal generator module 250 to produce data read signal D_RD, and transfers to external daughter board 120 by bus-bar 130.Then, enter step S450, digital independent control module 240 judges whether the reading access signal RD_AS (not having the sign of RD_AS in Fig. 2) of external daughter board 120 is ready to complete.If reading access signal RD_AS was not also ready to complete more than a schedule time by external daughter board 120, then digital independent control module 240 comes back to step S440 with the data read signal D_RD that retransfers.
After external daughter board 120 receives data read signal D_RD, just can utilize shift registor 125 that the driving data of parallel transmission is converted to the driving data of serial transmission, be read access signal RD_AS the driving data of serial transmission to be used as.Then, to send signal by bus-bar 130 ready to make digital independent control module 240 learn to read access signal RD_AS for external daughter board 120.
In step S460, the driving data of serial transmission to read access signal RD_AS from external daughter board 120 received in sequence, and is changed and keeps in as driving data arranged side by side by the digital independent control module 240 control data working storage 260 in displacement busbar unit 230.By this, in step S470, digital independent control module 240 controls output switch 280 to be stored in temporary storage location 290 by the driving data of above-mentioned external daughter board 120, digital independent control module 240 also can transmit a reading settling signal RD_OK to power supply timing unit 220, reads to complete single.Application the present embodiment person should know, above-mentioned continuous read mode or fixed interval read mode are after single read mode completes, power supply timing unit 220 immediately or postpone again to send after a fixed interval to read enable signal RD_EN, to make displacement busbar unit 230 continuously and repeatedly to carry out above-mentioned reading flow process.
In this special instruction, the present embodiment is illustrated by power initiation sequential, uses and enables those skilled in the art more understand the embodiment of the present invention.Fig. 5 A and Fig. 5 B illustrates the relation schematic diagram in power supply sequential between multiple power supply stage and reading enable signal RD_EN.Please refer to Fig. 5 A and coordinate Fig. 2, when computer installation 200 has just connected AC power (such as, 110V/220V civil power) time, power supply timing unit 220 just can start the pre-stand-by power source stage P1 performing power supply sequential, and it is the pre-stand-by power source of sequential start according to voltage quasi position from large to small.Time shared by pre-stand-by power source stage P1 is very of short duration, and now detects external daughter board 120 and there is no substantial benefit, therefore only need read its driving data with single read mode.In other words, power supply timing unit 220 is once enable to reading enable signal RD_EN, now read driving data is called it is the first driving data herein.
After pre-stand-by power source all starts, power supply sequential just enters direct current and to leave unused stage P2.In the present embodiment, whether couple may there is no real benefit owing to detecting external daughter board 120 at this moment, therefore the direct current stage P2 that leaves unused corresponding can stop read mode, makes reading enable signal RD_EN be all forbidden energy, uses and continue to stop reading its driving data (as solid line L1).But, in section Example, baseboard management controller 170 must monitor the change conditions of each element of whole computer installation 200, therefore, when the power supply stage of computer installation 200 be direct current leave unused stage P2 time, power supply timing unit 220 also can be set as continuous read mode or fixed interval read mode (such as dotted line L2), makes reading enable signal RD_EN enable continuously, uses the driving data continuing to read up-to-date external daughter board 120.
