Whether the attribute information of band, which needs, pre-processes, and step 3 is performed for the order that needs pre-process, for the life that need not be pre-processed
Order performs step 4；
Step 3, for the graphics command that pre-processes of needs, order entrained attribute information handle after and update,
Perform step 4；
Step 4, the graphics command for receiving are to judge current Graphics instruction according to graphics command service condition code
It is no to be immediately performed, if can be immediately performed, step 5 is performed, otherwise, performs step 7.
Step 5, the difference according to graphics command, selection, which performs, sends command code, configuration attribute register and initiation data
At least one of transmission operation in the process of implementation, according to graphics command function, if desired calls common process interface, then
It performs step 6 and returns, step 2 is performed after a graphics command has been handled；If need not if, refer to having handled a figure
Step 2 is performed after order；
Step 6 can selectively call running state monitoring, error handle, data format to turn according to the different of graphics command
It changes, matrix management common process interface；
When step 7, current Graphics instruction cannot be immediately performed, judge whether the processing procedure is overtime, if overtime, perform step
Error handle in rapid 6 if having not timed out, performs step 4, judges whether that the instruction can be performed again.
It is an advantage of the invention that：
The present invention provides a kind of efficient graphics command resolution design method, reduces the dependence of processing procedure, avoids
It is unnecessary redirect caused by overhead, for the analytical design method of graphics command provide effective support.
Description of the drawings
Fig. 1 is the functional block diagram of the present invention.
Specific embodiment
In the following with reference to the drawings and specific embodiments, technical scheme is clearly and completely stated.Obviously,
The embodiment stated only is part of the embodiment of the present invention, instead of all the embodiments, based on the embodiments of the present invention,
Those skilled in the art are not making creative work premise all other embodiments obtained, belong to the guarantor of the present invention
Protect scope.
A kind of graphics command resolution design method, including：
Step 1, the graphics command coding of receiving host transmission；
Step 2 instructs generation graphics command service condition coding according to current Graphics, judges that current graphics command is taken
Whether the attribute information of band, which needs, pre-processes, and step 3 is performed for the order that needs pre-process, for the life that need not be pre-processed
Order performs step 4；
Step 3, for the graphics command that pre-processes of needs, order entrained attribute information handle after and update,
Perform step 4；
Step 4, the graphics command for receiving are to judge current Graphics instruction according to graphics command service condition code
It is no to be immediately performed, if can be immediately performed, step 5 is performed, otherwise, performs step 7.
Step 5, the difference according to graphics command, selection, which performs, sends command code, configuration attribute register and initiation data
At least one of transmission operation in the process of implementation, according to graphics command function, if desired calls common process interface, then
It performs step 6 and returns, step 2 is performed after a graphics command has been handled；If need not if, refer to having handled a figure
Step 2 is performed after order；
Step 6 can selectively call running state monitoring, error handle, data format to turn according to the different of graphics command
It changes, matrix management common process interface；
When step 7, current Graphics instruction cannot be immediately performed, judge whether the processing procedure is overtime, if overtime, perform step
Error handle in rapid 6 if having not timed out, performs step 4, judges whether that the instruction can be performed again.
Embodiment
As shown in Figure 1, a kind of efficient graphics command resolution design method, this method is divided into graphics command preparation, figure refers to
Processing, common interface is made to handle three levels.Graphics command preparation includes the acquisition of (1) graphics command；(2) graphics command is known
Not；(3) graphic attribute storage and pretreatment；(4) judgement of graphics command service condition is met；Graphics command processing includes (5)
Graphics command processing；The common interface stage includes the processing of (6) common interface；(7) time-out judges
(1) graphics command obtains, and realizes the graphics command coding of receiving host transmission, and it is known to (2) graphics command
Not.
(2) graphics command identifies, according to the graphics command received, first determines whether the attribute information entrained by present instruction
Whether need and handle, if desired, graphics command is then issued into the storage of (3) graphic attribute and pretreatment；Secondly generation figure refers to
Service condition code is made, is stored for (3) graphic attribute and judges to use with pre-processing.
(3) graphic attribute storage and pretreatment, this step is not essential process flow, just for need attribute storage with
The graphics command of pretreatment.It is sent to by the attribute information that attribute information new after pretreatment is instead preceding, and by graphics command
(4) judgement of graphics command service condition is met.
(4) judgement of graphics command service condition is met, the graphics command generated in being identified according to step (2) graphics command is transported
Whether row condition code can be immediately performed to judge that current Graphics instruct, if can be immediately performed, graphics command is sent to (5) figure
Instruction is handled, and otherwise, graphics command is sent (7) time-out and is judged.
(5) graphics command is handled, and includes transmission command code, configuration attribute register and initiation data transmission three parts,
According to the difference of graphics command, selection performs function above, can be called in graphics command process flow in the processing of (6) common interface
Processing Interface after return, and next graphics command is identified after graphics command has been handled.
(6) common interface is handled, and is included running state monitoring, error handle, Data Format Transform, matrix management etc. and is connect
Mouthful, the processing of common interface function in the processing of (5) graphics command is completed, returns to the processing of (5) graphics command after finishing.
(7) time-out judges, if realizing processing when current Graphics instruction cannot be immediately performed.If cannot be immediately performed and not
Time-out then cycles wait；The error handling interface in the processing of (6) common interface is called if time-out.
Finally it should be noted that more than fact Example is merely illustrative of the technical solution of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that；It still may be used
To modify to the technical solution that foregoing embodiments are recorded or carry out equivalent substitution to which part technical characteristic；And
These modifications are replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of various embodiments of the present invention technical solution
It encloses.
