Abstract

PURPOSE:To quickly generate the final result of shift operation by outputting upper bits resulting from addition of upper bits of addition data as partial shift data. CONSTITUTION:Each module outputs corresponding one of signals UG1-UG3, which indicates success of the condition that carry C63 generated in lower eight bits by inputted addition data a0-63 and b0-63 is transmitted up to the weight position of the fourth bit from the most significant bit, to the just higher-order module. Each module reports corresponding one of signals UP1-UP3, which indicates success of the condition that carry is transmitted up to the weight position of the fourth bit from the least significant bit, to the just higher-order module. Only upper eight bits of inputted addition data are added, and data corresponding to upper four bits of the addition result is generated as partial shift data and is transferred to the just higher-order module as R16-19, R32-35, and R48-51.
