Paper Abstract

In this paper a novel MDCT without multiplications has been presented via transforming it into the computation of the first-order moment. Then the method proposed for computing moments has been adapted to implement the arbitrary-length MDCT efficiently. A very simple and scalable systolic array without multipliers and ROMs has also been designed to perform the MDCT, which can result in the efficient VLSI implementation easily. And the comparison with some existing methods shows the superiority of our method.
