Rapidly prototyping DSP extensions using CoDeL: the DWT using lifting

In this report, we present CoDeL, a rapid hardware prototyping language, to implement a DSP module which performs the biorthogonal one-dimensional discrete wavelet transform using the lifting technique. Specifically, we implement the wavelet transform using the Le Gall integer-to-integer 5/3 filter bank. Using CoDeL, we show how this wavelet transform can be implemented with just a few lines of code
