A parametric DCT architecture for H.263+ mobile terminals video streaming

Due to the recent wireless market explosion, it is forecastable that in the near future, mobile terminals will deploy both voice and true multimedia services. In this framework, the need for a low-power, multimedia oriented IP is noted. In particular, since the greater part of video coding standards rely on common functionalities, it is very important to develop a library of parametric IP. The main aim of this paper is to discuss a parametric architecture for the discrete cosine transform (DCT). The proposed architecture is intended to be used as a transform stage in a mobile H.263+ codec. What is striking about this core is that it is able to sustain a full-motion PAL video streaming operating at a frequency of 74 MHz with 39 mW of dynamic power dissipation.
