What is a reversible computer technology?
Since the density and speed of switching our computing devices continue to increase exponentially, the amount of energy distracted by these devices must remain at a certain level, otherwise economically impractical cooling apparatus is required. Conventional computers perform thermodynamically irreversible logical operations, that is, it is not possible to extrapolate the previous states of machines based solely on information from future countries. Information in the form of bits is deleted. This bit of erase represents entropy that is correlated with a heat scatter. Around 2015, however, the development reaches the basic barrier - KT barrier - which represents the amount of energy calculated by multiplying the temperature of the computing environment (generally room or 300 Kelvin temperature) by the Boltzmann constant. The only way to penetrate this barrier is to reduce the temperature of our computers or develop a thermodynamically reversible computers that do not generate entropy and therefore dispel almost as much heat as conventional, irreversible computers.
Creating reversible computers is a significantly more attractive option than cooling, as the reduction of the computing environment to the lowest reaching temperature (~ 0 Kelvin) reduces only the energy scatter per unit of volume by two orders, while building reversible computers allows energy scattering to reduce arbitrarily.
.By building computers that perform reversible logical operations, the heat scattering levels can be achieved. The disadvantage is that reversible architecture can become quite complicated. When 2015 is approaching and the calculation industry begins to approach the KT barrier, it is a liqueur that the compilers will be designed to maximize the number of thermodynamically reversible operations in conventional computational architectures. When we begin to think about computers constructed from very small and fast logical gates like in nanocomput, reversibility becomes more thana narrow function to maintain energy scattering at tolerable levels.
Research in a reversible calculation today is a pioneer of MIT, whose project the pendulum was specially created to propose a fully reversible computational architecture. Since maximum achievable computer efficiency is necessarily formed by reversible architecture, this area of research is necessary if the strength and economy of our computers continue to increase.
