Description
Technical field
The present invention relates to Computer display technical field, and in particular to a kind of quick display based on domestic processor platform
Apparatus and method.
Background technology
Currently, in the BIOS based on domestic CPU platforms, the initialization for display device is swept in PCI-E bus apparatus
Carried out after retouching and initializing.Due to platform architecture and bios code performance reason, lighted from An County power key to display, most
It is fast about 12 seconds, there is very big gap with X86 platforms.Display continues blank screen in the meantime, and computer, which can not be provided a user, appoints
What feeds back, and is easily caused user and is mistakenly considered system and delay machine or situations such as go wrong, has a strong impact on Consumer's Experience.
The content of the invention
The technical problem to be solved in the present invention is：The present invention is put down for problem above there is provided one kind based on domestic processor
The quick display device and method of platform.
The technical solution adopted in the present invention is：
A kind of quick display device based on domestic processor platform, described device includes following four module：
A, PCI-E bus operation module, it is main to be responsible for the corresponding PCI-E controllers of operation display controller, complete necessary
PCI-E bus operations；
B, display controller initialization module, selection complete display device using X86 simulators and initialized；
C, LOGO display function module, for writing data to video memory, show LOGO；
D, Debugging message output function module, provide Debugging message output to BIOS and other modules and service.
The PCI-E bus operations module groundwork has following items：
1）Complete the corresponding PCI-E controllers PCI-E link registers initialization of display controller；
2) display controller PCI link initialization of register is completed；
3) initialization of display controller PCI base registers is completed.
The display controller initialization module and the function mould called in BIOS Plays display device initialization procedures
Block is shared, and major function is to perform the code being integrated in video card VBIOS, completes display controller initialization.Due to initialization
Code is directly integrated in video card VBIOS, therefore preferable for the compatibility of video card, and execution efficiency is high.
A kind of fast display method based on domestic processor platform, methods described is after BIOS startups, C stacks（Order stack,
Link stack）After the completion of initialization, the functional module is loaded immediately, is completed corresponding display function initialization, is rapidly completed display
The functions such as LOGO, display Debugging message.
Beneficial effects of the present invention are：
The present invention can be rapidly completed the functions such as display LOGO, display Debugging message.Display shows that the time only about needs 3 seconds.
To provide to user or developer while computer starting and effectively feed back, the use of user can be greatly improved
Impression, while developer can be facilitated to carry out hardware and software debugging.
Embodiment
With reference to embodiment, the present invention is further described：
Embodiment 1：
A kind of quick display device based on domestic processor platform, described device includes following four module：
A, PCI-E bus operation module, it is main to be responsible for the corresponding PCI-E controllers of operation display controller, complete necessary
PCI-E bus operations；Because now PCI-E controllers not yet complete initialization, standard operating instruction and correlation function still can not
With, therefore this module is used, and it is main to be responsible for the corresponding PCI-E controllers of operation display controller, complete necessary PCI-E buses
Operation；
B, display controller initialization module, selection complete display device using X86 simulators and initialized；
Because the technology of the present invention is mainly used in the non-X86 platforms of domestic CPU, to strengthen the compatibility to display controller, reduction by two
Secondary development difficulty, selection completes display device using X86 simulators and initialized；
C, LOGO display function module, for writing data to video memory, show LOGO；
D, Debugging message output function module, provide Debugging message output to BIOS and other modules and service.
Embodiment 2：
On the basis of embodiment 1, PCI-E bus operations module groundwork described in the present embodiment has following items：
1）Complete the corresponding PCI-E controllers PCI-E link registers initialization of display controller；
2) display controller PCI link initialization of register is completed；
3) initialization of display controller PCI base registers is completed.
Embodiment 3：
On the basis of embodiment 1 or 2, display controller initialization module shows with BIOS Plays and set described in the present embodiment 3
The functional module called in standby initialization procedure is shared, and major function is to perform the code being integrated in video card VBIOS, completes aobvious
Show that controller is initialized.Because setup code is directly integrated in video card VBIOS, thus it is preferable for the compatibility of video card,
And execution efficiency is high.
Embodiment 4：
On the basis of embodiment 2, a kind of fast display method based on domestic processor platform of the present embodiment, methods described exists
After BIOS starts, C stacks（Order stack, link stack）After the completion of initialization, the functional module is loaded immediately, completes corresponding display work(
It can initialize, be rapidly completed the functions such as display LOGO, display Debugging message.
Embodiment is merely to illustrate the present invention, and not limitation of the present invention, about the ordinary skill of technical field
Personnel, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all equivalent
Technical scheme fall within scope of the invention, scope of patent protection of the invention should be defined by the claims.
