Embodiment
The invention provides a kind of method that can switch the computer applications formula immediately.
Fig. 1 shows system architecture diagram of the present invention.
The present invention is mainly on keyboard 30 fast key is set, after pressing fast key, central processing unit 10 sees through the application that basic output/input system 20 starts corresponding fast key in the storage device 40, wherein the essential hardware peripheral equipment of several of each application correspondence can be initialised, then can initialization as for other and the not corresponding hardware peripheral equipment of application that starts, so can accelerate starting up speed.
The input control of keyboard 30 is by keyboard controller (Keyboard Controller) control, and keyboard controller has:
(a) buffer memory (Buffer) can store the input data of keyboard.
(b) scan code (Scan Code) is used for comparing the data of input.
(c) send the demand of interrupting (Interrupt Request)
When pressing a certain key, corresponding key pulse (Keystroke) can appear, keyboard controller is found out corresponding piling up by scan code (Scan code) and is placed buffer memory then, then keyboard controller is sent the demand of interrupting and is given central processing unit, central processing unit is written into and carries out the corresponding service formula that interrupts demand, and last central processing unit reads in data by buffer memory.
So, promptly send key pulse to keyboard controller, and deposit in the buffer memory through output/input port (I/Oport) when the user press fast key on the lower keyboard 30.Scan code is after comparing this key pulse, and with piling up at buffer memory of correspondence, basic output/input system reads this yard and presses the fast key of which application to judge the user, to switch to the application corresponding formula.
With general normal startup computer operating system, putting down in writing a lot of order of booting computer standard program in the basic output/input system 20, when computer power starting, at first can start shooting according to the boot program order of being put down in writing in the boot program memory body:
I. power-on starts every hardware peripheral equipment.
II. output/input system 20 is written in the memory body substantially.
III. central processing unit 10 is sought basic output/input system 20 to specific memory body position.
IV. central processing unit 10 moves on other address and carries out formula according to basic output/input system 20.
V. to storage device 40 (normally hard disc) look for, the initiating task system, and will give that operating system is opened, control with manage computer hardware.
Have three big elements in the basic output/input system 20:
Basic output/input system ROM (ROM):
Be ROM, record is main source code in the output/input system 20 substantially.Most basic in recent years output/input systems 20 have been used fast flash memory bank (Flash ROM), can utilize specific formula to go to revise formula in basic output/input system ROM, to deal with soft, the hardware device of renewal.
Basic output/input system complementary metal oxide formula semiconductor (CMOS):
Store and to need the setting revised usually.For example hard disc form, connector specification etc.In boot program, the data that can revise all be stored in the complementary metal oxide formula semi-conductive in.
Basic output/input system battery:
For the required electric power of complementary metal oxide formula semiconductor record data.Early stage motherboard is the configuration rechargeable battery, but many in recent years use mercury batteries provide electric power.
General formula can be divided into system program and application two big classes, system program refers to the formula of master control computer running, comprise basic output/input system, operating system (OS, OperatingSystem), and tool software (for example: magnetic disc planning software, sweep-drug software, formula develop software ... Deng); Application then is to be additional to computer to make its formula that more meets user's demand, for example: browser, document software for editing, mapping software, Games Software ... briefly, the application framework is on system program and the formula that development is come out.
In the present invention, before basic output/input system 20 starts application, earlier will be corresponding to the hardware peripheral equipment initialization of application, for instance, if will play MP3, initialized possibly hardware peripheral equipment comprises video graphics array (VGA) 80, screen 85, integrated magnetic disc electrical interface (IDE) 90 and laser disc 93.
Fig. 2 is for realizing flow chart of steps of the present invention.
At first, in outer several independently fast key that is provided with of original computor-keyboard, wherein, a fast key can start a corresponding embedded system of application (A, B, C represent application respectively), and this fast key is designed to possess power up function, promptly presses above-mentioned fast key and can start shooting.
Step S1 presses first fast key.At the application that institute's desire starts, press corresponding fast key, computer system also starts thereupon.
Step S11 initiating hardware peripheral equipment.The hardware peripheral equipment that will correspond to the embedded system of first fast key through basic output/input system carries out initialization.
Step S2 starts first embedded system.After pressing first fast key, in start process, the basic output of computer system/input system inquiry keyboard controller (also can be described as embedded controller, Embedded Controller) the fast key state of being replied, can learn that present system is with the start of first fast key, therefore starts first embedded system.
Step S3 presses second fast key.If this moment, desire was used the Another Application formula, then press another fast key to start another embedded system.
Step S31 initiating hardware peripheral equipment.The hardware peripheral equipment that will correspond to the embedded system of second fast key through basic output/input system carries out initialization.
Step S4 starts second embedded system.After pressing second fast key, in start process, the fast key state that the basic output of computer system/input system inquiry keyboard controller is replied can learn that present system is with the start of second fast key, therefore starts second embedded system.
Step S5 closes first embedded system.After starting second embedded system, because of temporarily not using first embedded system, so close first embedded system to save system resource.
According to the fast key of being pressed, basic its relevant hardware of output/input system initialization, thus enter the embedded system of its respective application formula, because of other hardware that is not used is not initialised, so can shorten the on time.If will switch to other application, press corresponding fast key and can enter corresponding embedded system, same, the hardware that an initialization is used, so can reduce the time of other required wait of hardware that is not initialised of initialization, can reach the purpose of instant switch application formula.
The present invention is independent with the function that various general users use always, realize in the embedded system mode, significantly shorten the time that the user waits for, make the product of class household electrical appliances, the function that not only has personal computer system, each multimedia function also can be independent separately.The global function of PC is combined with embedded system, make PC not only have extendibility, conformability, also have the independence of each function simultaneously concurrently, allow the user can arbitraryly control the function of various PC.
