8 X 8 DISCRETE COSINE TRANSFORMS ON TMS320C25/TMS320C30(CONTAINS SCANNED TEXT)

The 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 TMS320C25 and TMS320C30 processors

- TMS320C25 code for a roundoff routine

- Signal flow graphs for 2-2-point, 4-point, and 8-point DCTs

- TMS320C30 code for bit reversal

- Execution times and memory requirements

The appendices at the end of the book contain code for the DCT algorithms for both the TMS320C25 and TMS320C30 processors.
