Network processors afford a great degree of flexibility to
current day routers, yet they still have followed the trend
of being largely specialized to the domain of route table
look-up. By using a processor architecture that is more gen-
eral purpose, routers can gain from economies of scale and
increased programmatic flexibility. We propose the use of
the Raw Processor [5] as both a network processor and
switch fabric for multi-gigabit IP routing. While previous
general purpose architectures have failed to give a useful
programmatic interface to sufficient bandwidth to support
multi-gigabit IP routing, the Raw Processor, through its
tiled architecture and software exposed on-chip network-
ing, has enough internal and external bandwidth to deal
