Based on new and fast convolution approach
Efficient memory area (in-place)
Article I use: World Academy of Science, Engineering and Technology , VLSI Design of 2-D Discrete Wavelet Transform for Area-Efficient and High-Speed Image Computing, by Mountassar Maamoun, Mehdi Neggazi, Abdelhamid Meraghni, and Daoud Berkani.

4. Project milestones Learn the 2D-DWT algorithm from the article
Write floating point MATLAB DWT and IDWT
Choose coefficients
Compare the results to MATLAB DWT function
Write fixed point MATLAB DWT and IDWT
Select the fixed point resolution
Architecture:
Learn the proposed architecture from the paper
Adjust it to our case - different coefficients and picture size
Code the module in VHDL
Simulate the module using ModelSim
Synthesis of the module using Vivado
