dc.description.abstractThis paper presents two bus coding schemes for power optimization
of application-specific systems: Partial Bus-Invert coding and its
extension to Multiway Partial Bus-Invert coding. In the first scheme, only
a selected subgroup of bus lines is encoded to avoid unnecessary inversion
of relatively inactive and/or uncorrelated bus lines which are not included
in the subgroup. In the extended scheme, we partition a bus into multiple
subbuses by clustering highly correlated bus lines and then encode each
subbus independently. We describe a heuristic algorithm of partitioning a
bus into subbuses for each encoding scheme. Experimental results for various
examples indicate that both encoding schemes are highly efficient for
application-specific systems.
