Method and system for performing two-dimensional transform on data value array with reduced power consumption

摘要: A method and system for performing a 2D transform is disclosed. The may include row and/or column transform. When the or transform, it be determined whether each of different subsets data values including partition includes at least one zero value, first subset other value. transformation operation on value bypassed performed in reduced-power manner, where such would otherwise manner consuming full power if were non-zero
