Abstract
A method and system for increasing the throughput of video input and output operations in a computer system is provided. In a memory mapped video environment the preferred embodiment increases the speed of video access by redirecting the video I/O to system RAM and updating the actual memory mapped video asynchronously. Thus full CPU speed is attained in assembling the images, while the screen image is copied to video memory in the background and while the CPU is idle.
