Abstract
A hardware implementations of Montgomery modular multiplication are described. The number of components as well as the number of cycles may be reduced by using a lookup table and multiplexer for selecting terms to be added during calculations. Also a loop unrolling technique may be used improve performance. A chain of pipeline adder modules and a chain of delay and shift modules may be used to pipeline calculations of multiple sets of operands.
