Abstract
A modular arithmetic unit includes a first input generator receiving first data to generate a first operand; a second input generator receiving second data to generate a second operand; an accumulator performing an accumulate/shift operation to add the first and second operands and outputting the carry and sum; a carry propagation adder adding the carry and the sum to output a result; and a data handler receiving either external data or the result and outputting the first data and the second data.
