Abstract
A back end unit for use with a graphics processor includes an input for receiving graphics data streams from the graphics processor, an output for transmitting graphics data streams, and a plurality of paths, coupled with the input and output, that direct graphics data streams between the input and the output. The plurality of paths direct data between the various modules that are a part of the back end unit. To that end, among other things, the back end unit also includes a gamma correction module that applies gamma correction operations to graphics data streams, a cursor module that adds cursor data to graphics data streams, and a digital to analog converter that converts the graphics data streams from a digital format to an analog format. The plurality of paths thus permit graphics data streams to pass through no more than two of the gamma correction module, the cursor module, and the digital to analog converter.
