【Abstract】 The theory of wavelet transform algorithm and its applications are firstly introduced in this paper. Some questions in the use of Mallat algorithm are then analyzed. The implementations of parallel multiply and add instructions, circular addressing mode and repeat mode operation in wavelet algorithms are also put forward. The wavelet algorithm is emulated with DSP development system finally. The result of emulations indicates that the implementation of wavelet algorithm on DSP can satisfy requirements of real time usage.
