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 micropipeline 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.<>
