ADDER SUPPORTING MULTIPLE DATA TYPES, AND METHOD OF SUPPORTING ADDITION AND SUBTRACTION IN MULTIPLE DATA TYPES USING SAID ADDER

摘要

An adder for supporting multiple data types by controlling a carry propagation is provided. In an example, the adder supports a subtraction operation of a maximum n-bit data types, and includes a plurality of the first addition areas each formed with a predetermined unit number of bits and configured to receive pieces of incoming operand data, and one or more second addition areas each formed between the plurality of the first addition areas and configured to receive pieces of control data based on an operand data type and an operation type.
