All internal functions measure their own progress and operate as fast as the technology allows.
The objective of this work was to demonstrate the potential power savings and on-chip space savings which accrue from removing the clock. In a conventional modern processor, the clock causes power to be consumed at all times. Asynchronous logic, such as that used in Amulet 1 only uses power in proportion to the current work-load. The work was supported by Advanced RISC Machines Ltd, who supplied design libraries and have subsequently licensed the technology from the University.
