Claim One:
1. A video graphics module comprises: a plurality of video graphics pipelines, wherein each of the plurality of video graphics pipelines is operable to process a corresponding image layer and wherein one of the plurality of video graphics pipelines processes a foremost graphics image layer and the video graphics pipelines is operable to process the corresponding image layers in parallel, wherein each of the foremost graphics image layer and the corresponding image layers are operatively received from at least one frame buffer; and a blending module operably coupled to the plurality of video graphics pipelines, wherein the blending module is operable to blend the corresponding image layers in a predetermined blending order, thereby creating an intermediate blended image, and blending the intermediate blended image with the foremost graphics image layer, to produce an output image having the foremost graphics image layer blended in a foremost position with respect to the other corresponding image layers with negligible loss of information of the other corresponding image layers, wherein the blending module is selectably controllable to blend the intermediate blended image with the foremost graphics image layer in accordance with an alpha blending convention or an AND/XOR blending convention; wherein the blending module comprises a first mixing module and a second mixing module, wherein the first mixing module is operable to blend at least two of the corresponding image layers to produce the intermediate blended image, and wherein the second mixing module is operable to blend the foremost graphics image layer with the intermediate blended image.
