Program of efficient implementation of the discrete cosine transform of type-II using cyclic convolutions have been considered. The stages of automatic code generation of computing of DCT-II for arbitrary size N have been determined. The algorithm of DCT-II presents a better program performance for sizes of transform less than N=100, if compared with FFTW library.
