Abstract :
To design a 32-bit logarithmic number system (LNS) processor, this paper presents two novel techniques: Digit-Partition (DP) to design log 2(1.x) function and Iterative Difference by Linear Approximation (IDLA) to design 20.x function. The experimental result reveals that the proposed design is more attractive than the previous researches in the LNS processor
