Abstract
The application of coding strategies is an established
methodology to improve the characteristics of on-chip intercon-
nect architectures. Therefore, design methods are required which
realize the corresponding encoders and decoders with as small
as possible overhead in terms of power and delay. In the past,
conventional design methods have been applied for this purpose.
This work proposes an entirely new direction which exploits
design methods for reversible circuits. Here, much progress has
been made in the last years. The resulting reversible circuits
represent one-to-one mappings which can inherently work as
logical descriptions for the desired encoders and decoders. Both,
an exact and a heuristic synthesis approach, are introduced which
rely on reversible design principles but also incorporate objectives
from on-chip interconnect architectures.
Experiments show that significant improvements with respect
to power consumption, area, and delay can be achieved using the
proposed direction.
