中文摘要	a novel optoelectronic quotient-selected modified signed-digit division technique is proposed. this division method generates one quotient digit per iteration involving only one shift operation, one quotient selection operation and one addition/subtraction operation. the quotient digit can be selected by observing three most significant digits of the partial remainder independent of the divisor. two algorithms based on truth-table look-up and binary logic operations are derived. for optoelectronic implementation, an efficient shared content-addressable memory based architecture as well as compact logic array processor based architecture with an electron-trapping device is proposed. performance evaluation of the proposed optoelectronic quotient-selected division shows that it is faster than the previously reported convergence division approach. finally, proof-of-principle experimental results are presented to verify the effectiveness of the proposed technique.
