<span title="2005-07-01">2005</span> <i title="SPIE"> Visual Communications and Image Processing 2005 </i> &nbsp;
MPEG-4 has many computationally demanding underlying algorithms, an example of which is the Shape Adaptive Discrete Cosine Transform (SA-DCT).  ...  The entire design has been synthesized using TSMC 0.09µm TCBN90LP technology yielding a gate count of 12028 for the datapath and its control logic.  ...  ACKNOWLEDGMENTS The support of the Research Innovation Fund of Enterprise Ireland and the Embark Initiative is gratefully acknowledged.  ...
