ABSTRACT:
A method and apparatus for pixel conversion using multiple buffers includes receiving a position value including a horizontal value and a vertical value. The method and apparatus further includes receiving a byte per pixel value and a pixels per group. The method and apparatus further includes determining a pitch value for each of the multiple buffers and determining an offset value for each of the multiple buffers. The method and apparatus further includes assigning each of the multiple buffers to varying buffer locations within a frame buffer based on the position value, the byte per pixel value and the pixels per group value such that a first and second converted pixel values may be equivalent to a first and second corresponding assigned buffer location.
