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] It can be inferred from the passage that the author would be more optimistic about optical computing if which of the following were true?
选项
A、Digital partitioning algorithms could be applied to electronic, and not just optical circuits.
B、The speed of photons could be shown to be significantly greater than that of electrons.
C、The precision level in basic operations can be substantially increased without great expense.
D、The accuracy of electronic circuits used to preprocess input data and post- process data could be greatly increased.
E、The microchips optical computer systems were shown to require an increasing density of interconnections.
