Discrete cosine transform chip using neural network concepts for calculating values of a discrete cosine transform function

摘要

A discrete cosine transform chip includes circuits using neural network concepts that have parallel processing capability as well as conventional digital logic circuits. In particular, the discrete cosine transform chip includes a cosine term processing portion, a multiplier, an adder, a subtractor, and two groups of latches. The multiplier, the adder and the subtractor incorporated in the discrete cosine transform chip use unidirectional feed back neural network models.
