Description of drawings

Fig. 1 is a kind of based on the hardware-accelerated video memory control and treatment method embodiment schematic flow sheet of playing up technology for the present invention.

Embodiment

Specify the preferred embodiments of the present invention below in conjunction with accompanying drawing.

See also Fig. 1, it is a kind of based on the hardware-accelerated video memory control and treatment method embodiment schematic flow sheet of playing up technology.

It is a kind of based on the hardware-accelerated video memory control and treatment method of playing up technology that the present invention provides, and it comprises:

Step 1, input render objects;

Step 2, render objects is carried out cutting; In the present embodiment, the method for render objects being carried out cutting comprises: the display screen area of display is divided by piece, when render objects corresponds on this display screen, correspondingly carry out cutting by piece;

Whether step 3, the render objects of judging present frame change with respect to the render objects of previous frame, if then execution in step 4, otherwise, execution in step 6;

Step 4, the render objects of cutting is indicated,, can all be labeled as the piece at render objects place dirty such as in the present embodiment;

Can understand like this, when the picture on certain piece changes, also promptly should the zone dirty;

Step 5, the render objects of cutting put into play up formation;

Step 6, judge whether the render objects of cutting all carried out cutting, if then execution in step 7, otherwise, execution in step 2;

The render objects whether cutting is arranged in the formation is played up in step 7, judgement, if then execution in step 8, otherwise, execution in step 11;

Step 8, in buffer memory, search and play up the texture that needs, and judge whether to find, if then execution in step 9, otherwise, execution in step 10;

Step 9, the texture of playing up needs that will find are sent into video card and are played up, and execution in step 7 again;

The texture that needs is played up in step 10, application, and copies buffer memory to, and execution in step 9 again;

Whether step 11, determining program finish, if then execution in step 12, otherwise, execution in step 1;

Step 12, end.

Above-mentioned a kind of based on the hardware-accelerated video memory control and treatment method of playing up technology, in the process that realizes, can adopt following technology:

1, pinup picture caching technology: when starting when playing, in video card, distribute one group of video memory page of specifying size in advance, the physical size of the pinup picture that the page can use according to playing is cut apart again, and such page just can be placed a plurality of pinup pictures as required; In operational process, through certain strategy to the replacement Treatment (as: LRU) that wears out of the pinup picture in the buffer memory.For each pinup picture that gets into buffer memory, need to use some algorithm (as: hash etc.) to carry out mark, so that when playing up, can from buffer memory, obtain needed buffer memory pinup picture fast, effectively avoided data redundancy simultaneously.

2, the dirty rectangle technology played up of hardware: at first create one than games window big slightly be equipped with screen, according to certain size this is shielded piecemeal fully then; During drafting, calculate institute's rendered object in the position that is equipped with screen and this object at the piece that is equipped with screen, and carry out cutting according to the piece under it, the rendered object after the cutting is joined successively plays up in the chained list; If the object of current drafting with respect to previous frame state variation (as: position, animation broadcast frame etc. change) has taken place, then when drawing, need notify each affiliated piece of this object to play up; When all objects that need draw after all cutting finishes, traversal is played up chained list, searches the object that all need be played up; If residing needs of this object are played up again, then play up this object, otherwise do not play up; Because being cut into the rendered object of several sections is continuous in playing up chained list; During drafting, can the part that need to change be played up for synthetic one batch, guarantee the efficient of playing up.In addition,, therefore when moving among a small circle, only need the position of adjustment viewport, need not the whole screen that is equipped with is redrawn, have only when viewport to have exceeded when shielding scope fully, just wipe to be equipped with and shield, repaint all pieces because it is big slightly than games window to be equipped with screen.
