Discrete Wavelet Transform
"The BA113FDWT IP core performs hardware 2D multi-level Discrete Wavelet Transform in either lossless or lossy mode with full compatibility with JPEG2000 Standard (ISO/IEC 15444-1). The core is optimized for speed and is suited for high-end applications involving real-time video (e.g. SDTV or more). It features a 16-bit datapath and is able to decompose tiles of size up to 128 by 128 pixels into up to 5 levels of decomposition.
