ABSTRACT:
A system for calculating the discrete cosine transform of dimension M*M which is orthogonal and separable under the form of two monodimensional transforms calculated by a fast algorithm, by operating on incoming and outgoing words, in the form of parallel bits, and by operating on the data internally in the system in words represented by 2M bits. The operations of addition and subtraction between variable data and the operations of multiplying by the variable data using fixed coefficients are made on the data represented in the form of M couples of serialized bits, so that the speed of the incoming and outgoing words, in the form of words of parallel bits, is equal to the speed of bit couples that represent the internal data. A circuit implemented onto a silicon base for implementation the fulfillment of this system includes at least: an input interface; a converter for incoming words for the conversion from the form of parallel bits to the form of words represented by serial bit couples for the incoming words and vice versa for the outgoing words; a first operator for the discrete cosine transform (DCT) monodimensional transform; a transpositor from lines to columns; a second operator for monodimensional transform; and a scaling device for outgoing words.
