In-place averaging of packed pixel data
Abstract:
Methods, systems, and apparatuses for averaging data in packed format are provided. The data may be image data, such as data words containing color-specific data portions representative of pixels of a captured image. A first data word containing first image data is received. A second data word containing second image data is received. A logical AND of the first data word and the second data word is performed to generate a third data word. A logical exclusive OR (XOR) of the first data word and the second data word is performed to generate a fourth data word. A right shift of the fourth data word is performed. The third data word and the right shifted fourth data word are summed to generate a fifth data word that is an average of the first and second data words.
