Sensor network processors and their applications are a grow-
ing area of focus in computer system research and design. Inher-
ent to this design space is a reduced processing performance re-
quirement and extremely high energy constraints, such that sen-
sor network processors must execute low-performance tasks for
long durations on small energy supplies. In this paper, we demon-
strate that subthreshold-voltage circuit design (400 mV and be-
low) lends itself well to the performance and energy demands of
sensor network processors. Moreover, we show that the landscape
for microarchitectural energy optimization dramatically changes
in the subthreshold domain. The dominance of leakage power in
the subthreshold regime demands architectures that i) reduce over-
