AMULET3: A High-Performance Self-Timed ARM Microprocessor
S.B. Furber, J.D. Garside, D.A. Gilbert
AMULET3 is a fully asynchronous implementation of ARM architecture v4T and was designed at the University of Manchester between 1996 and 1998. It is the third generation asynchronous ARM, and is aimed at a significantly higher performance level than its predecessors. Achieving this higher performance has required significant enhancements to the internal micro-architecture, such as the introduction of a reorder buffer to support efficient forwarding while retaining exact exception handling.
In this paper we present an overview of the AMULET3 core, highlighting the issues which arise when striving for high performance and instruction set compatibility in an asynchronous design framework.PDF (32K). IEEE Copyright
