—Biosequence alignment recently received an amazing support from both commodity and dedicated hardware platforms. The limitless requirements of this application motivate the search for improved implementations to boost processing time and capabilities. We propose an unprecedented hardware improvement to the classic Smith-Waterman (S-W) algorithm based on a(More)
Many <i>facts</i> about emerging nanotechnologies are yet to be assessed. There are still major concerns, for instance, about maximum achievable device density, or about which architecture is best fit for a specific application. Growing complexity requires taking into account many aspects of technology, application and architecture <i>at the same time</i>.(More)
Among the emerging technologies Field-Coupled devices like Quantum dot Cellular Automata are one of the most interesting. Of all the practical implementations of this principle NanoMagnet Logic shows many important features, such like a very low power consumption and the feasibility with up-to-date technology. However its working principle, based on the(More)

The promising features of Nanoscale array structures pave the way for interesting applications like biosequence alignment, that currently can be addressed only at the price of a huge overhead in terms of area and power dissipation. Nanofabrics, once technology will be mature enough, are expected to enormously overcome these limits, and assure an evident(More)
• We conceive a tool for enabling the design and simulation of parallel nanoarchitectures. • We develop specific algorithms to design layout of circuits based on silicon nanoarrays. • We enable the fast simulation of circuits based on nanoarrays at behavioral level. • We extract spice-equivalent netlists of circuits for physical level simulation. • We(More)
— Nanoscale arrays based on nanowires are expected to have a promising future thanks to their amazing density and regularity. Experiments demonstrated the feasibility of this technology and pointed out that accurate reliability analyses should be accomplished to assure proper yield requirements. Due to the complexity of these systems and the arising(More)
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—Nanowire Field Effect Transistors (FETs) with multiple independent gates around a silicon channel feature ultimate gate control and are regarded as promising candidates for next generation(More)
Density and regularity are deemed as the major advantages of nanoarray architectures based on nanowires. Literature demonstrated that proper reliability analyzes must be performed and solutions have to be devised to improve nanoarrays yield. Their complexity and high-fault probability claim for specific design automation tools able to explore circuit(More)
