Abstract
AMULET1 demonstrated the feasibility of building an asynchronous
implementation of the ARM microprocessor. Although functional, this first
asynchronous ARM microprocessor did not fully exploit the potential of the
asynchronous design style to deliver improved performance and power
consumption.
This paper describes AMULET2e, an embedded system chip incorporating an
enhanced asynchronous ARM core (AMULET2), a 4 Kbyte pipelined cache, a
flexible memory interface and assorted programmable control
functions. AMULET2e silicon demonstrates competitive performance and
power-efficiency, ease of design, and innovative features that exploit its
asynchronous operation to advantage in power-sensitive applications.
