Wat is an amulet?

AMULET is a series of microprocessors that implement the ARM processor architecture. Developed by the Advanced Processor Technologies group under the University of Manchester's computer science school (formerly the AMULET and PAL groups based at the same institution), AMULET is unique from other ARM implementations in that it is an asynchronous microprocessor, not making use of a square wave clock signal for data synchronization and movement.
