ABSTRACT
The recent proliferation of computing technology has brought
added interest to natural I/O interface technologies such
as speech recognition. Unfortunately, the computational
and memory demands of such applications currently pro-
hibit their use on low­power portable devices in anything
more than their simplest forms. Previous work has demon-
strated that the thread level concurrency inherent in this
application domain can be used to dramatically improve
performance with minimal impact on overall system energy
consumption, but that such benefits are severely constrained
by memory system bandwidth. This work presents a design
space exploration of potential memory system architectures.
A range of low­power memory organizations are considered,
