Airbus do not stipulate a procedure for eng failure on final approach in CAT I or better conditions.
Airbus do state ECAM actions at least 400' above the runway for takeoff approach or go-around. The also state in FCOM 3 (A320 3.02.01) 'In some emergency cases, provided the appropriate flight path is established, the pilot flying may initiate ECAM actions before this height.
I believe the references in FCOM 4 Flight Phase Related Procedures refer to CAT II/III approaches where ECAM actions must be completed prior to 1000'.
In CAT III DUAL if below alert height (100' radio A320 family) then you may continue and autoland after an engine failure.
CAT I approaches are not subject to the same regulation and below 1000', I believe it is acceptable to carry on, stopping ECAM at 400' to concentrate on landing the aircraft, or if on fire invoking the 'In some emergency cases........' clause.
Assuming A/THR is engaged at the time of failure and flap full is selected with the aircraft stable prior to the failure if my memory is correct all you would have to do is place the thrust levers in the MCT gate when the FMA prompts you, centre the slip indicator & trim the rudder. Sorted. ECAM actions down to 400', land, complete ECAM actions. (And don't forget the landing checklist!)
Of course in a 737..............
