Abstract
An apparatus and method for processing display data in multi-pixel sections which also tracks and maps a cursor in single pixel increments is disclosed. A video buffer card receives display data and generates display control data for a multi-pixel section of display frame, and cursor display information including cursor enable information, cursor color selection information, cursor color and blending information, and X and Y cursor location information. Additionally, the current horizontal and vertical location of the multi-pixel section of the display data is tracked and used in combination with the cursor X and Y location information to calculate an offset that is used to replace certain portions of the display data with cursor color information. The video buffer card also supports a blending operation which provides a blend of the cursor foreground and background colors with the displayed image colors.
