ABSTRACT:
A computer video display acceleration system and method is disclosed for increasing the speed with which modifications can be made to video memory. This system and method uses a video buffer section in system memory with high priority access by a central processing unit which can use the buffer space to make changes rapidly in the stored video information. Once the changes are completed, the data stored in the buffer is written as a block of data to video memory without requiring additional video memory read cycles.
