Abstract
The Residue Logarithmic Number System (RLNS) uses the Residue Number System (RNS) to represent logarithms that represent real values. Multiplication and division are easy; reasonable-precision addition and subtraction have not been economical because of RNS sign-detection. This paper adapts novel interpolation (for addition) and cotransformation (for subtraction) to fit the sign-detection limits. Smaller than prior RLNS hardware, the novel ALU defers sign detection with two speculative datapaths.
