Title: Efficient Implementation of the Discrete Wavelet Transform on
Digital Signal Processors

e-mail: t.sinnwell@rz.uni-sb.de

Abstract:

The wavelet transform (WT) is a very powerful tool for the analysis of
transient signals. An efficient implementation of the discrete form of
the wavelet transform on digital signal processors (DSPs) is
especially interesting for the analysis of real time signals. The
present paper begins by presenting and discussing the continuous
wavelet transform. The transition to the discrete WT is then explained
and executed. After a short discussion of the possibilities of
implementing the discrete WT, the implementation of the periodic
extension of the discrete WT on digital signal processors is
described. Within this context, special attention is given to circular
addressing as a special form of indirect addressing. The corresponding
assembly code is described for the digital signal processor TMS320C3X
series from Texas Instruments.

Keywords: Wavelet transform (WT), Multiresolution analysis (MRA), Digital
signal processors (DSPs)

Status: Submitted to Applied Signal Processing
