reversible sequential computing in sections 4 and 5, we started from a certain computing object (viz., a finite func- tion), and we discussed the conditions for its reversible realization first (a) as an object of the same nature (viz., an invertible finite function) treated as a "lumped" system, t h u s stressing functional aspects, and then …

Reversible Computing is about being able to obtain, from a result, the values that originated it (one by one). As we well know, our computers work with a binary system whose values, true or false ( on/off if we think of transistors as light bulbs), and the logical operations on the bits are diverse.

Part of the Lecture Notes in Computer Science book series (LNCS,volume 85) Abstract The theory of reversible computing is based on invertible primitives and composition rules that preserve invertibility.

The Future of Computing Depends on Making It Reversible It's time to embrace reversible computing, which could offer dramatic improvements in energy efficiency Michael P. Frank 25 Aug 2017 10 min read Illustration: Chad Hagen

Reversible computing, in a general sense, means computing using reversible operations, that is, operations that can be easily and exactly reversed, or undone. In technical terms, a reversible operation performs a bijective transformation of its local configuration space.

2.3 Reversible Computing Reversibility of computation has been studied in several works [10, 26, 64] with a first aim to reduce the energy dissipation due to the irreversibility of computing process. A computing is reversible if we can always reconstruct a previous state from the actual state as it is shown in Figure 2.2.

Reversible computing is computing such that, not only can you get from the input to the output, but you can take the output and drive the computation backward to get the input. It is of interest for a couple of reasons. Alex Niemeyer has already mentioned the thermodynamics, so I won't go into that. However, there's a more important reason.

With reversible computers, you won't emit any heat. You won't erase anything, either; you can mark a bit as erased, but it's there if you want to retrieve it. It can cost more or less, but you never really lose anything. It's inevitable to draw some parallelisms with real life. Life is irreversible, that is, time can only go forwards.

One of the outside runners in the race to take the world of logic by storm is reversible computing. By that, computer scientists mean computation that takes place in steps that are time...

What's Reversible Computing? Broadly speaking, there are two different levels of reversible computing: Logically reversible computing means computing in such a way that it always remains possible to efficiently reconstruct the previous state of the computation from the current state. (Follow the above link for more details.)

Reversible computing is a paradigm where computing models are defined so that they reflect physical reversibility, one of the fundamental microscopic physical property of Nature. Also, it is one of the basic microscopic physical laws of nature. Reversible computing refers tothe computation that could always be reversed to recover its earlier state.

Environment Location. Cherkasy is situated on the high right bank of the Dnipro River, in the middle of the Kremenchuk Reservoir.Relief of the historical part of the city was influenced by Zamkova (Castle) mountain, where Cherkasy Castle was situated. The major part of Cherkasy occurs as lowlands.. The city occupies an area of 69 km 2 (26.6 sq mi). The city's length is 17 km (10.56 mi) along ...

A reversible computing system is defined as a "backwarddeterministic" system, where every computational configuration (state of the whole system) has exactly one previous configuration. Hence,a backward computation can be performed by its "inverse" computing system.

It explores up-and-coming theories, techniques, and tools for the application of reversible computing―the logical next step in the evolution of computing systems. The book covers theory, hardware and software aspects, fundamental limits, complexity analyses, practical algorithms, compilers, efficiency improvement techniques, and application areas.

Reversible computing's efficient use of heat could make it possible to come up with 3-D chip designs, Bennett said. This would push all of the circuitry closer together and ultimately increase performance. Frank is currently coming up with ways to outfit chip designs with the oscillators. More information on his work can be found here.

mike frank: reversible computing refers to computation using logically reversible (invertible) transformations of the digital state of the machine, transformations that are also carried out using physical mechanisms that are (almost) thermodynamically reversible - that is, mechanisms that produce no, or negligibly small amounts of, physical …

What is reversible computing? At it's core, reversible computing is exactly as it sounds: computations that can be reversed. Think of a simple program that adds a to b.A reversible system would allow this transaction to be 'undone' and have a and b revert to their initial states. You may be thinking "Well that's already possible, it's called the undo button!".

The theory of reversible computing is based on invertib|e primitives and composition rules that preserve invertibility. With these constraints, one can still satisfactorily deal with both functional and structural aspects of computing processes; at the same time, one attains a closer correspondence between the behavior of abstract computing systems and the microscopic physical laws (which are ...

Reversible computing is an unconventional computing model where the computational process to some extent is time-reversible. One neat consequence of that fact is that reversible computers are the only ones with the potential, in principle, to dissipate arbitrarily little heat. You won't see "Moore's law" being praised much, here.
