AMULET1 was the world's first asynchronous implementation of a commercial microprocessor architecture. It executes standard ARM code, and proved that complex asynchronous design is feasible. AMULET1 was recognised with one of three 1995 British Computer Society Awards
Advanced RISC Machines Limited, the owners of the ARM architecture, have an agreement with the University which gives them rights the the AMULET processor technology and allows us to offer the 'ARM Research Studentship' to a worthy candidate.
The AMULET2e microprocessor, a chip with an enhanced AMULET processor core and an on-chip cache memory, has been fabricated and demonstrated. It shows significant power saving opportunities and much lower electromagnetic emission than a comparable synchronous chip. It has a simple external interface and is a flexible embedded processing unit.
Construction a radically redesigned AMULET3 processor has already started. This will offer much more processing power without compromising energy efficiency or EMC. The chip incorporates a number of new design features, and problems such as asynchronous on-chip buses and internal DMA are being addressed.
We are getting increasingly close to commercial viability, and future research plans revolve around making the technology more attractive to our industrial collaborators. Students are welcome to join the group to work in any relevant areas. Suggested topics are:
The Department of Computer Science at the University of Manchester has many other research activities and opportunities.
