This course aims at giving the student a detailed overview of the computation circuits and systems for computations that are expected to become the main actor in the forthcoming scenario, going beyonf the ultra-scaled CMOS technologies and focusing the attention on the emerging technologies among which the winner is still to be defined. Those devices, circuits and systems will be analyzed considering the connection among CMOS and beyond COMS devices with circuits and architectures based on them. This because the complexity of nanoscale systems does not allow to disentangle different planes as design, analysis and evaluation.

It is preferable to have understanding of digital circuits, knlowledges of devices and circuits based on CMOS technology and processing systems based on CMOS. In case these knwloedges would be missing the students will be given material for compensation.
