Acquisition and processing of measurement signals via microprocessors - Technologies: current trends and turn-key systems

In the first 2 parts [R 525v2] and [R 526v2] , we reviewed the architecture of a microprocessor-based data acquisition and processing chain, distinguishing its fundamental components and illustrating their specific roles with selected examples (first and second booklets). This third fascicule completes this architectural vision by evoking current technologies: a brief overview of the different families of microprocessors, with the aim of highlighting their advantages and disadvantages in the context of our application (chapter 1), is followed by an evocation of a few families of commercial systems enabling the "turnkey" resolution of a certain number of classic data acquisition and processing problems (chapter 2).
