AMULET3: a 100 MIPS Asynchronous Embedded Processor

S. B. Furber, D. A. Edwards and J. D. Garside


AMULET3 is a 32-bit asynchronous processor core that is fully instruction set compatible with the clocked ARM cores. It represents the culmination of ten years of research and development into asynchronous processor design at the University of Manchester, and is the first step into commercial use for this technology.

AMULET3 shows that asynchronous technology is commercially viable, and is competitive in terms of performance, area and power-efficiency with clocked design. In addition, asynchronous design offers significant advantages in terms of reduced electromagnetic interference and unique power management capabilities.
