Design and Analysis of Defect- and Fault-tolerant Nano-Computing Systems
… One approach for developing robust digital systems from such unreliable nanodevices is to introduce defect- and fault-tolerance at the architecture level. Structurally redundant architectures, reconfigurable architectures and architectures that are a hybrid of the previous two have …

Ψηφιακές και υπολογιστικές συντεταγμένες : προς μια ερμηνεία της εισαγωγής της ψηφιακής σχεδίασης και του υπολογιστικού σχεδιασμού στην αρχιτεκτονική εκπαίδευση
Η νέα χιλιετία βρίσκει το πεδίο της αρχιτεκτονικής να εισέρχεται σε μια “Ψηφιακή” εποχή, την οποία μπορούμε – τηρουμένων των αναλογιών – να παραλληλίσουμε με την “Νέα Εποχή” της Βιομηχανικής Επανάστασης των αρχών του 20ου αιώνα. Η εισαγωγή του Ψηφιακού Ηλεκτρονικού Υπολογιστή – ως φορέα του …

Cross-layer methods for energy-efficient inference using in-memory architectures
… challenge. In conventional von Neumann architectures, the energy and latency cost of realizing ML algorithms is dominated by memory accesses. To address this issue, the deep in-memory architecture (DIMA) was proposed, which embeds mixed-signal computation as an integral part of the …
