High Precision DCT CORDIC Architectures for Maximum PSNR [PDF]
Cet article propose deux architectures optimales DCT (Discrete Cosine Transform algorithm) basées sur Cordic Loeffler : une architecture DCT rapide et de faible puissance et une architecture DCT PSNR élevée. Les paramètres de rotation des angles CORDIC requis pour ces architectures ont été calculés à l'aide d'un script Matlab. Ce script permet de faire
