ABSTRACT:
Integrated circuits capable of carrying out transformations of the "cosine transformation" type, used more particularly for the digital processing of images with a view to information compression. The versatile and compact circuit architecture involves dividing a bus into sections separated by switches actuated in phase opposition; certain sections are coupled to computing operators, whereas others are coupled to memories serving for reorganizing the order in which the data is presented to the following operators.
