Four-Phase Micropipeline Latch Control Circuits
Stephen B. Furber and Paul Day
Abstract
Standard micropipelines use simple two-phase control circuits.
The latches employed on AMULET1 are level-sensitive, so two-
to four-phase converters are required in each latch controller.
To avoid this overhead an investigation has been carried out
into four-phase micropipeline control circuits; this has thrown
up several design issues relating to cost, performance and
safety, and forms a useful illustration of asynchronous design
techniques.
