8 X 8 Discrete Cosine Transforms on TMS320C25/TMS320C30 (Contains Scanned Text)
Texas InstrumentsThe Discrete Cosine Transform (DCT) stands apart from other orthogonal transforms because of its favorable comparison to the Karhunen-Loeve Transform (KLT). However there is no fast algorithm to compute the KLT which makes the DCT an attractive alternative. This book presents two 8X8 DCT routines and is divided into the following pieces:- The DCT algorithm- Implementation in the TMS320C2
