中文摘要	we present, for the first time to our knowledge, a generalized lookahead logic algorithm for number conversion from signed-digit to complement representation. by properly encoding the signed-digits, all the operations are performed by binary logic, and unified logical expressions can be obtained for conversion from modified-signed-digit (msd) to 2's complement, trinary signed-digit (tsd) to 3's complement, and quarternary signed-digit (qsd) to 4's complement. for optical implementation, a parallel logical array module using an electron-trapping device is employed and experimental results are shown. this optical module is suitable for implementing complex logic functions in the form of the sum of the product. the algorithm and architecture are compatible with a general-purpose optoelectronic computing system.
