Abstract
A method used to test the correctness of image data transited between the system memory and display memory is described as follows. First, a image data A is stored in a location B of the system memory. Then, the data of image A and a location C of display memory are stored into a Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A stored in the location B of system memory to the location C of display memory. Then, the data of location C, location D of display memory, and image A are input into the Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A from the location C to the location D of display memory. The data of image A and location E are input into the Bitblt temporary storage means. The Bitblt engine is used to transit the data of image A from the location D into the location E of the system memory. Then, the image data A in location B of system memory is compared with the image data A in location E of system memory for determining whether the image data A is correct after the transiting procedure completed.
