Abstract
This paper explores the architectural challenges introduced by emerging
bottom-up fabrication of nanoelectronic circuits and develops an
architecture that meets these challenges. While our implementation is based
on one specific technology, we believe the architecture is compatible with
other emerging technologies. The specific nanotechnology we explore uses
patterned DNA nanostructures and carbon nanotube FETs to create a
hierarchical design. Patterned DNA nanostructures provide a scaffold for
the placement and interconnection of CNFETs to create a limited size
circuit (node). These nodes are interconnected using DNA-guided
self-assembly, but without the control available in the patterned
nanostructures, thus producing a random interconnect. Three characteristics
of this technology that significantly impact architecture are 1) limited
node size, 2) random node interconnection, and 3) high defect rates. We
present an accumulator-based active network architecture that addresses
these three challenges.
