| Abstract(in English) | In this study, we propose reverse converters for moduli set ${2^k,2^n+1,2^n-1}$ that convert residue number system to weighted number system. By using SD(Signed-Digit) number and SD number addition algorithm, we can reduce number of modular addition of reverse conversion. Moreover, we consider a method that can detect a number is represented by a negative value and obtain an equivalent positive value of the residue SD number that may take negative values at a higher speed by using SD-binary subtraction algorithm. We have designed the reverse conversion circuit with a hardware description language by using a 0.18{textmu}m CMOS gate array technology library. |
