ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to integrated circuits, and more particularly to an integrated circuit graphics display system.
BACKGROUND OF THE INVENTION
Graphics display systems are typically used in television control electronics, such as set top boxes, integrated digital TVs, and home network computers. Graphics display systems typically include a display engine that may perform display functions. The display engine is the part of the graphics display system that receives display pixel data from any combination of locally attached video and graphics input ports, processes the data in some way, and produces final display pixels as output.
This application includes references to both graphics and video, which reflects in certain ways the structure of the hardware itself. This split does not, however, imply the existence of any fundamental difference between graphics and video, and in fact much of the functionality is common to both. Graphics as used herein may include graphics, text and video.
SUMMARY OF THE INVENTION
The present invention provides a graphics accelerator that includes a memory for graphics data. The graphics accelerator preferably includes a coprocessor for performing vector type operations on a plurality of components of one pixel of the graphics data.
