Abstract :
AMULET2e is an embedded system chip incorporating a 32-bit ARM-compatible asynchronous processor core, a 4-Kb pipelined cache, a flexible memory interface with dynamic bus sizing, and assorted programmable control functions. Many on-chip performance-enhancing and power-saving features are switchable, enabling detailed experimental analysis of their effectiveness. AMULET2e silicon demonstrates competitive performance and power efficiency, ease of system design, and it includes innovative features that exploit its asynchronous operation to advantage in applications that require low standby power and/or freedom from the electromagnetic interference generated by system clocks
