Abstract
A display mode processor which maps pixel inputs into addresses for entries in window-specific color look-up tables in accordance with a predetermined display mode. The display mode processor relieves the central processing unit from video display tasks in a multi-window environment and also supports window-specific attributes such as display mode in addition to window specific color look up tables. This dedicated hardware for video display tasks allows for a more flexible and efficient color display system without sacrificing the overall system performance.
