AMULET1, developed in the OMI-MAP project, showed that complex asynchronous design is feasible. AMULET2e, developed in the OMI-DE project, is the next step in establishing self-timed processing as a commercially viable technology. It incorporates a new core, AMULET2, which is significantly faster than AMULET1, together with on-chip RAM which can be configured as a fixed block of RAM or as a cache. A flexible memory interface supports a 'conventional' external memory and peripheral system, freeing the board-level designer from the asynchronous timing concerns which have made some previous self-timed chips (including AMULET1) difficult to use as components.
