Summary: Abstract
The general purpose processor has long been the focus
of intense optimization efforts that have resulted in an
impressive doubling of performance every 18 months.
However, recent evidence suggests that these efforts
may be faltering as pipelining and ILP processing tech-
niques experience diminishing returns. Application spe-
cific architectures hold great potential as an alternative
means to continue scaling application performance. The
approach works by specializing a design to a small
domain of important applications, and it benefits from
improved performance, greater power efficiency, and
reduced area costs. This technique is well matched to
embedded targets, where application domains are typi-
cally narrow.
In this paper we present a case study of an application
specific processor design. Our design, called the Cryp-
toManiac processor, is an architecture specialized to
efficiently execute cryptographic ciphers. We carefully
highlight the domain specific application characteristics
