This paper presents a new dynamic non-uniform segmentation method for the first-order polynomial function evaluation. The proposed method can evaluate the elementary functions (e.g. log, exp, sin, cos, tan, etc.) and combinations of these functions by an optimized linear approximation with the fewest non-uniform segments. Compared with the previous evaluation method based on the static bit-width analysis,...
This paper presents a novel design and implementation of a 7-digit fixed-point decimal-to-decimal antilogarithmic converter. A linear approximation algorithm is proposed and simulated in MATLAB models. The maximum absolute error of the proposed decimal antilogarithmic converter is in the range of -0.000999 les Eabsolute les 0.000857 and the maximum percent error is in the range of -0.000715 les Epercent...
