Abstract

A method and system for applying pipeline architecture to discrete cosine transform and inverse discrete cosine transform. Each of the discrete cosine transform and inverse cosine transform are divided into four phases computed by process elements. Each phase can be designed by adjusting the amount of process elements according the demand of performance.
