An amulet is an object whose most important characteristic is the power ascribed to it to protect its owner from danger or harm. Amulets are different from talismans as a talisman is believed to bring luck or some other benefit, though it can offer protection as well. Amulets are often confused with pendants—charms that hang from necklaces—any given pendant may indeed be an amulet, but so may any other charm which purports to protect its owner from danger.

AMULET is a series of microprocessors implementing the ARM processor architecture. Developed by the Advanced Processor Technologies group at the School of Computer Science at the University of Manchester (formerly the AMULET and PAL groups based at the same institution), AMULET is unique amongst ARM implementations in being an asynchronous microprocessor, not making use of a square wave clock signal for data synchronization and movement.
