ABSTRACT:
An integrated circuit data processing structure and method for performing a discrete cosine transform (DCT) makes the correspondence between a table f(x,y) of N.times.N data and a table F(u,v) of N.times.N coefficients according to the following relation: ##EQU1## The innovative structure uses: a memory containing a data table;
