摘要: This paper describes the project of a processor for calculation direct/inverse two-dimensional discrete cosine transform to be employed in videoconference applications. makes use separability technique as method and an architecture based on distributed arithmetic, which multipliers are replaced by accumulation-and-shift blocks. The was implemented AMS 0.8 /spl mu/m technology with semi-custom approach order realize IP macro-cell integrated multimedia ICs. It features very low-complexity (15 kgates) overall area 33 mm/sup 2/ maximum frequency 36 MHz. Besides, is fully compliant accuracy specifications H.263 recommendation.
