Four-phase micropipeline latch control circuits

摘要

Standard micropipelines use simple two-phase control circuits. Thenlatches employed on AMULET1 are level sensitive, so two- to four-phasenconverters are required in each latch controller. To avoid this overheadnan investigation has been carried out into four-phase micropipelinencontrol circuits; this has thrown up several design issues relating toncost, performance and safety, and forms a useful illustration ofnasynchronous design techniques
