@ Daryo Thank you very much for info. Language is simpler, easy to understand, all I have to do is convince client o rewrite the title and abstract. Althea`s refs seem fine. I`ll let you know how I get on with client.

I would get rid of "offset" as it's no more than a misleading and unnecessary "synonym" for shifting (bits of a register), and stick to the terminology used in the very relevant references found by Althea Draper.

Such a multiplier (/multiplication unit (?) operating by...) by shifting and adding typically comprises a plurality of shifters (/shifter units), each shifter (/shifter unit) being connected to the input and configured to shift the input value to the left by a predefined number of bits; and a set of adders (/ adder units) connected directly to the output of the shifters (/shifter units) and configured to sum the outputs of the shifters (/shifter units).

BTW "shift" is one of the most basic commands in "bare metal" computer programming.

@ Samuel In the translated text we have "offset and addition " followed by "shifts which appears to replace the offset. What if any is the difference between shift and offset?

Samuël Buysschaert Jul 30, 2021:

@agree with Tony and Conor The text mentions "unités de décalage" so shift units is correct,
shifter is "registre à décalage" if i am not mistaken. // what i mean by that is shifter unit feels weird, as shifter = unité de décalage in the references, to quote "Les unités de calcul, 3 unités: UAL, multiplieur, registre de décalage (shifter)" 'Unité de décalage (Shifter)"; would stick with shift unit.

Althea Draper Jul 30, 2021:

I think it might be shifter units and adder units. Have a look at the following
https://constellation.uqac.ca/509/1/24625610.pdf page 21 under "Multipliers" "Décalage et addition — Un opérande est décalé à gauche d'un bit par cycle et est appliqué à un additionneur lorsque le bit correspondant du second opérande est haut. Cette technique donne des mises en œuvre compactes, mais très lentes, nécessitant N cycles d'horloge pour se compléter, et ne permet pas le chevauchement des calculs. Arbre logique - Chacun des bits résultants sont une fonction logique des bits associés de chaque opérande. Cela donne une grande structure à entrance élevée, envisageable jusqu'à 32 bits"

@ Asker No, we wouldn't say 'sum' units (though we might do) — it's difficult to explain, it's just that it 'feels' wrong; I think it's because we are more used in everyday language to use 'sum' and 'summing', whereas 'shift' is not a normal operator in arithmetic. It just feels to me as if one might consider that the unit 'creates' a 'shift', whereas we don't think of an adder as 'creating a sum' (OK, it does, literally — but we don't really analyse it down to that level in everyday use)
There's 'clunky' and 'clunky' — patentese is clunky in a specific way, compared to everyday EN — but when you get bits that sound clunky even to the jargon-attuned ears of a specialist in the field, you can start to suspect soemthing's amiss.

Bashiqa (asker) Jul 30, 2021:

@ Tony My choice is shift units, but would we also say sum units? Re clunky phrase, patents are mostly clunky. If it was left to me I`d delete about 50% of the text, I`d also lose my job.

Tony M Jul 30, 2021:

@ Asker I'd say 'shift units' — avoid the '-ing', it's used like a different part of speech in this context. Cf. expressions like 'shift register' etc.

I'm not too sure about that "multiplier by offset and addition" either... sounds clunky to me, not natural jargon. I'd expect something more like 'shift/add multiplier' etc.

Bashiqa (asker) Jul 30, 2021:

@ Any answerers Just noticed that there are summing units, so perhaps "shifting units" is OK.
