Electronic computer speeds are restricted not only by the speed of electrons
in matter but also by the escalating density of interconnections necessary to
connect the electronic gates on microchips. Electrical engineers and physicists
Line have been developing and augmenting the technologies of analog and digital
(5) optical computing, in which the information is primarily carried by photons
rather than by electrons. Optical computing could, in principle, generate much
higher computer speeds, but one of the problems it has encountered lies in
accuracy, for these devices have practical limits of 8 to 11 bits of accuracy in
basic operations. Recent research has evinced that digital partitioning
(10) algorithms in tandem with error-correction codes, can substantially enhance the
accuracy of optical computing operations. In the near term optical computers
will most likely be hybrid optical/electronic systems that preprocess input data
for computation and post-process output data via electronic circuits, but
nevertheless, the prospect of all-optical computing remains highly attractive. [br] Which of the following can be inferred from the passage about the technology employed in optical computing?
选项
A、The technology is more expensive to develop than the technology that was required in electronic computing.
B、The search for technology necessary for all-optical computing is considered unfeasible and has been largely abandoned.
C、Optical computers systems that rely on digital partitioning algorithms in tandem with error-correction codes are considered hybrid technology.
D、The technology necessary for digital optical computing appears within closer reach than the technology for analog optical computing.
E、The most feasible version of optical computing at present is a synthesis of electronic and optical technology.
