Abstract:
A data processing method comprising the steps of:(a) processing an N.times.N first matrix, consisting of each N data to be processed arranged in every first and second directions, in every first direction by a first one-dimensional orthogonal transformation in order to obtain intermediate results, and obtaining an N.times.N second matrix by arranging said intermediate results, obtained in every first direction, in said second direction; and(b) obtaining transform values, forming an N.times.N third matrix, by processing said second matrix by a second one-dimensional orthogonal transformation in every first direction;wherein:a memory for storing said first and second matrices stores data arranged consecutively in said first direction, at consecutive addresses; andsaid first and second one-dimensional orthogonal transformations together serve as a two-dimensional orthogonal transformation for said data to be processed.
