Original Kurzfassung:
Adiabatic circuits are heavily investigated since they allow for computations
with an asymptotically close to zero energy dissipation
per operation?serving as an alternative technology for many scenarios
where energy efficiency is preferred over fast execution.
Their concepts are motivated by the fact that the information lost
from conventional circuits results in an entropy increase which
causes energy dissipation. To overcome this issue, computations
are performed in a (conditionally) reversible fashion which, additionally,
have to satisfy switching rules that are different from
conventional circuitry?crying out for dedicated design automation
solutions. While previous approaches either focus on their
electrical realization (resulting in small, hand-crafted circuits only)
or on designing fully reversible building blocks (an unnecessary
overhead), this work aims for providing an automatic and dedicated
design scheme that explicitly takes the recent findings in this
domain into account. To this end, we review the theoretical and
technical background of adiabatic circuits and present automated
methods that dedicatedly realize the desired function as an adiabatic
circuit. The resulting methods are further optimized?leading
to an automatic and efficient design automation for this promising
technology. Evaluations confirm the benefits and applicability of
the proposed solution.
