Four-phase micropipeline latch control circuits

S.B. Furber, P. Day
1996 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
Standard micropipelines use simple two-phase control circuits. The latches employed on AMULET1 are levelsensitive, 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  ...  An obvious way to avoid the conversion circuit cost is to implement the micropipeline handshake with four-phase signalling.  ...

Investigation into micropipeline latch design styles

P. Day, J.V. Woods
1995 IEEE Transactions on Very Large Scale Integration (vlsi) Systems  
An asynchronous implementation of the ARM microprocessor has been designed and fabricated based on Sutherland's Micropipeline approach.  ...  This paper assesses the effects of different design styles on the micropipeline latch structures used. The original design has latch structures based on passtransistor transparent latches.  ...  This simple micropipeline approach is therefore undesirable for the micropipeline structures used in the asynchronous ARM.  ...

Reduced complexity two-phase micropipeline latch controller

G.S. Taylor, G.M. Blair
1998 IEEE Journal of Solid-State Circuits  
A latch control circuit for two-phase micropipelines is presented and compared to previously published alternatives.

Abstract Modelling of Asynchronous Micropipeline Systems using Rainbow [chapter]

Howard Barringer, Donal Fellows, Graham Gough, Alan Williams
1997 Hardware Description Languages and their Applications  
We consider Sutherland's Micropipeline methodology for asynchronous hardware systems and highlight problems of design representation.  ...  The Rainbow hardware design framework supports such description, simulation and analysis of micropipeline systems. It provides a set of sub-languages each offering a different description style.  ...  Again, communication between elements uses micropipeline handshaking.  ...
