Perspectives of Using Oscillators for Computing and Signal Processing
It is an intriguing concept to use oscillators as fundamental building blocks
of electronic computers. The idea is not new, but is currently subject to
intense research as a part of the quest for 'beyond Moore' electronic devices.
In this paper we give an engineering-minded survey of oscillator-based
computing architectures, with the goal of understanding their promise and
limitations for next-generation computing. We will mostly discuss non-Boolean,
neurally-inspired computing concepts and put the emphasis on hardware and on
circuits where the oscillators are realized from emerging, nanoscale building
blocks. Despite all the promise that oscillatory computing holds, existing
literature gives very few clear-cut arguments about the possible benefits of
using oscillators in place of other analog nonlinear circuit elements. In this
survey we will argue for finding the rationale of using oscillatory building
blocks and call for benchmarking studies that compare oscillatory computing
circuits to level-based (analog) implementations
