中文摘要	a novel, to our knowledge, two-step digit-set-restricted modified signed-digit (msd) addition-subtraction algorithm is proposed. with the introduction of the reference digits, the operand words are mapped into an intermediate carry word with all digits restricted to the set {(1) over bar, 0} and an intermediate sum word with all digits restricted to the set {0, 1}, which can be summed to form the final result without carry generation. the operation can be performed in parallel by use of binary logic. an optical system that utilizes an electron-trapping device is suggested for accomplishing the required binary logic operations. by programming of the illumination of data arrays, any complex logic operations of multiple variables can be realized without additional temporal latency of the intermediate results. this technique has a high space-bandwidth product and signal-to-noise ratio. the main structure can be stacked to construct a compact optoelectronic msd adder-subtracter.
