Investigation into Micropipeline Latch Design Styles
Paul Day and J.Viv. Woods
Abstract
An asynchronous implementation of the ARM microprocessor has been designed
and fabricated based on Sutherland's Micropipeline approach. Reviews of
this work have shown that considerable performance improvement may be
possible in a number of key design areas. This paper assesses the effects
of different design styles on the micropipe- line latch structures used.
The original design has latch structures based on pass- transistor
transparent latches. An evaluation of the use of single-phase transparent
latch structures is given plus the application of 2-phase and 4-phase
control techniques.
