The procedure of the circuit for a linear transformation of clinical

摘要

Circuit for carrying out a linear transformation Xi/xi of N digital data items Xi into N digital data items xi. It comprises calculating means which determine the data xi by carrying out the whole of the processing in serial mode with the aid of 1-bit operators organised into a layered structure, a data item Xi passing, in the course of the processing, through the same number of layers whatever the path followed. It also comprises input/output means comprising N modules which put the data Xi received in parallel into series at the input, and, at the output, de-serialise the data Xi which are delivered in parallel. The circuit makes it possible to carry out discrete cosine transforms DCT or inverse discrete cosine transforms IDCT or other discrete linear transforms. Application to image, speech processing. IMAGE
