Abstract :
Real time implementation of wavelet transformations is becoming of great importance, since it is one of the key elements of JPEG2000 and MPEG4 encoding operations. This paper details a dedicated wavelet decomposition implementation for ADSP-BF533 and ADSP-BF561 fixed-point DSPs, and reports experimental results on several test images.
