Round 1

Reviewer 1 Report

The paper deals with a Finite Time Thermodynamic approach to the thermodynamics of computing. The paper addresses a standard model of computing where charged particles carry the information through the machine. (not a quantum computer). As in the endo reversible heat engine model temperature and chemical potential gaps are placed on the interface of the machine.to facilitate finite processing power. The study is a natural extension of the main ideas developed for heat engines.

What is missing from this analysis is some numbers for example for C-MOS to quantify the amount of entropy production.

Reviewer 2 Report

This is a very well written manuscript on the endoreversible modelling of information processing. It gives the reader a direct access into the thermodynamic and information-theoretic considerations for reversible and irreversible computing. The material is presented in a clear and structured fashion. I have only one remark for a potential improvement.

After eq. 3 one might expand the third sentence:

“We associate the microentropy with the heat Q, i.e. with that energy exchange, which would occur, if the microentropy enters or leaves the system at temperature T. According to . . . ”
