Abstract
En 中文
This brief presents a hardware-efficient logarithm circuit design based on a novel discontinuous piecewise linear approximation method. Hardware synthesis results targeted for a commercial application specific integrated circuit cell library and field-programmable gate array show the practicality of the proposed design. A new figure of merit that combines error, area, time, and power is introduced and used to show that the proposed method provides the designer with useful design options when implementing logarithmic conversion.
