8. Concluding remarks

As embedded and mobile systems are invisible computer systems, they naturally share many of the same characteristics as conventional computer systems. For low-end products, there are many of the features of the first microprocessor-based systems of the 1980s. For high-end multiprocessor systems-on-a-chip, there are many features in common with multicore or multicore clusters in terms of hardware, software and system design, design and validation issues. The specificity of embedded systems is the set of particular constraints we have reviewed: cost, size, energy, reliability, etc., which particularizes design and realization problems. Among embedded systems, critical systems are becoming increasingly important in certain fields, as can be seen from the steady increase in electronic systems in the automotive industry and the possibilities they open up (e.g. driverless cars).
