摘要: In this paper a generalized look-ahead logic algorithm for number conversion from signed-digit to its complement representation is developed. By properly encoding the signed digits, all operations are performed by binary logic, and unified logical expressions can be obtained modified-signed-digit (MSD) 2's complement, trinary (TSD) 3's quaternary (QSD) 4's complement. For optical implementation, parallel array module using electron-trapping device employed, which suitable realizing complex functions in form of sum-of-product. The proposed architecture compatible with general-purpose optoelectronic computing system.© (2001) COPYRIGHT SPIE--The International Society Optical Engineering.
