Describe the present invention below with reference to accompanying drawing, wherein:
Fig. 1 is the internal work calcspar of computer system of the present invention;
Fig. 2 is the schematic appearance of computer system shown in Figure 1;
Fig. 3 is the program flow diagram of computer system shown in Figure 1.
Embodiment
At first, with reference to Fig. 1 and Fig. 2.Fig. 1 is the internal work calcspar of computer system 62 of the present invention.Fig. 2 is the schematic appearance of computer system 62 shown in Figure 1.Present embodiment uses a notebook computer 62 as computer system of the present invention.The invention provides a kind of computer system, it includes a peripheral unit, a plurality of inner member, a circuit system 20, a control circuit.This peripheral unit includes a CD drive 34, an amplifier 40 and loudspeaker 42, is used for providing the peripheral function that can directly use to the user, for example plays a reproducing optical disk (audio CD).Circuit system 20 can connect a plurality of inner members via at least one bus 18,28,36, and to control the operation of each inner member, circuit system 20 is connected with described peripheral unit via a peripheral bus 36.Control circuit 14 then is used for the power supply supply of control system circuit 20 and CD drive, and after the power supply of described peripheral unit was unlocked, this peripheral unit can provide described peripheral function to the user, promptly plays described reproducing optical disk.
When circuit system 20 and described peripheral unit are in closed condition, when if control circuit 14 is received the open command of this peripheral unit that the user imports, control circuit 14 can be opened this peripheral unit, so that this peripheral unit can begin to provide the function of playing reproducing optical disk to this user.And when control circuit 14 receives that this user imports the operational order of this peripheral unit, control circuit 14 meeting open system circuit 20, so that circuit system 20 is via peripheral bus 36, control this peripheral unit to finish this operational order, and circuit system 20 then can be closed to save power supply after finishing this operational order.
As shown in Figure 1, this peripheral unit also includes sound effect processor 30 and path selector 32.Sound effect processor 30 is connected between CD drive 34 and the amplifier 40, being used for that the acoustic signal that CD drive 34 is exported is done audio handles, and circuit system 20 interconnects with sound effect processor 30 via a system bus 28, is used for controlling the processing capacity of sound effect processor 30.It still is amplifier 40 that path selector 32 then is used for selecting the acoustic signal that CD drive 34 is exported is sent to sound effect processor 30; When control circuit 14 is received the open command of this peripheral unit that this user imports, control circuit 14 can be opened CD drive 34, amplifier 40 and the path selector 32 of this peripheral unit, and control path selector 32, the acoustic signal that path selector 32 is exported CD drive 34 is sent to amplifier 40.
In addition, computer system 62 also includes battery 16, is connected with control circuit 14; When the voltage of being exported when battery 16 was enough kept the work of control circuit 14, control circuit 14 can be unlocked always, so that computer system 62 is maintained basic control function.
As Fig. 1 and shown in Figure 2, computer system 62 also includes peripheral control panel 12, be connected with control circuit 14, peripheral control panel 12 includes an open key and a plurality of operating key, play button as shown in the figure, Pause key, stop key, eject key, fast forward button and rewind key or the like, wherein when this open key is touched with the generation open command by the user, control circuit 14 can be opened this peripheral unit, so that this peripheral unit can begin to provide to this user the playing function of reproducing optical disk, and touched when producing operational order of this peripheral unit by the user when the arbitrary operating key in a plurality of operating keys, control circuit 14 meeting open system circuit 20 are so that circuit system 52 is controlled this peripheral unit to finish described operational order via peripheral bus 36.In addition, can establish a switch 38 in addition on the peripheral bus 36, when preventing to be in not open state, battery 16 is supplied to the power supply of CD drive 34 to flow backwards back in the circuit system 20.
Again with reference to figure 1, include a processor 22, a storer 24 in the circuit system 20 and be stored in basic input/output routine (BIOS) 26 in the storer 24, behind control circuit 14 open system circuit 20, processor 22 begins to carry out basic input/output routine 26, whether open key and arbitrary operating key that basic input/output routine 26 is then monitored peripheral control panel 12 were once touched by the user, if then circuit system 20 is controlled this peripheral unit to finish described operational order via peripheral bus 36.And circuit system 20 notifies control circuit 14 shutdown system circuit 20 to save power supply after finishing described operational order.
With reference to Fig. 3, Fig. 3 is the program flow diagram of computer system 62 shown in Figure 1.At first, system can check earlier whether computer system 62 is off-mode (44) at present, if not, then carries out the operation handling procedure (46) of common normal boot-strap state, and the reproducing optical disk pattern of play-overing then of the present invention is invalid.If, continue then to check that switch 10 on the computer system 62 makes does not switch to the reproducing optical disk pattern (48) of play-overing, if not, then similar with general open state, any peripheral unit is all invalid, can't use (50).If, continue then to check that the arbitrary button that whether has on the peripheral control panel 12 pressed (52) by the user, if have, then control circuit 14 is checked the key-press status (54) on the peripheral control panel 12, check it is which button is pressed actually, in case behind the button of having determined to press, control circuit 14 open system circuit 20 are handled the instruction of the button that is pressed, and will instruct and be sent to (56) on the CD drive 34 via peripheral bus 36, then, control circuit is after circuit system 20 is finished instruction, just circuit system 20 can be closed, and be sent to the instruction of CD drive 34, and can continue instruction to be sent to amplifier 40 via path selector 32, play out sound equipment (58) via loudspeaker 42 again.This is treatment scheme of the present invention.
Compared to the prior art, computer peripheral control method of the present invention and system can directly use this peripheral unit when off-mode, need not wait for the tediously long on time, also can reach the purpose of saving power supply; In addition, compare with the method for the known independent chip of configuration, the present invention has also saved the cost of this independent chip, and the circuit system 20 that directly utilizes computer system 62 itself to have is carried out identical functions, reached save time, power saving and economical optimum efficiency.
The above only is preferred embodiment of the present invention, and every various variations and modification of doing based on appended claim of the present invention is included within the patent of the present invention.
