An 800 Mpixels/s, ~260 LUTs Implementation of the QOI Lossle

This paper discusses the hardware implementation of an encoder and a decoder for the QOI lossless RGB image format. Some results are given for the AMD/Xilinx architecture, reaching over 800 Mpixels/s in Ultrascale+ and more than 4K@30 in Artix-7. A compression improvement up to ~15% is also observed when natural images are scanned along a Hilbert curve instead of the normal raster order.
