A custom processorbased on reconfigurable hardware technology isproposed in order to compute the figure of meritused to measure the quality of the fit ofX-ray diffraction peaks. As the experimentalX-ray profiles can present many peaks severelyoverlapped, it is necessary to select the bestmodel among a large set of reasonably goodsolutions. Determining the best solution iscomputationally intensive, because this is ahard combinatorial optimization problem. Theproposed processors, working in parallel,increase the performance relative to a softwareimplementation
