pipeline break
     
         (Or "pipeline stall") The delay caused on a
        processor using {pipelines} when a {transfer of control} is
        taken.  Normally when a control-transfer instruction (a
        branch, conditional branch, call or trap) is taken, any
        following instructions which have been loaded into the
        processor's {pipeline} must be discarded or "flushed" and new
        instructions loaded from the branch destination.  This
        introduces a delay before the processor can resume execution.
     
        "{Delayed control-transfer}" is a technique used to reduce
        this effect.
