A Realization Method of Forward Converters from Multiple-Precision Binary Numbers to Residue Numbers with Arbitrary Mutable Modulus

This paper presents a realization method of forward converters from multiple-precision binary numbers to residue numbers. Single-precision forward converters use conversion tables realized with memories. However, multiple-precision, e.g. more than 1024 bits, forward converters require huge memories. This paper proposes the circuit calculating a value in the conversion table in every clock cycle. Experimental results show that the proposed method can quadruplicate the dynamic range.
