FPGA design of Daubechies wavelet lifting scheme for audio processing

Project (M.S., Electrical and Electronic Engineering) -- California State University, Sacramento, 2008.

The goal of this project is to design and implement FPGA design of Daubechies
 lifting scheme for audio compression and reconstruction. The design approach is to use
 top down hierarchical design. The algorithm implemented performs compression and
 reconstruction for three levels. Daubechies scheme is recursive process in which output
 of previous level is input to another level and so forth. It was challenging to implement
 this project, as it needed lots of research effort for both software algorithm and hardware
 interface implementation. The completely audio compression system was implemented
 initially with Matlab and then with Verilog Hardware description language and emulated
 on Cyclone II FPGA of Altera DE2 kit. The algorithm generates satisfactory audio
 decompressed outputs.
