Field Programmable Gate Arrays constitute one of the technologies at hand for developing electronic systems. They form an attractive option for small production quantities as their non-recurrent engineering costs are much lower than those corresponding to ASIC's. They also offer flexibility and fast time-to-market. Furthermore, in order to reduce their size, and so the unit cost, an interesting possibility is to reconfigure them at run time so that the same programmable device can execute different predefined functions. §Complex systems generally are made up of processors executing programs,...
