Reversible Fault‐Tolerant Division Circuit
Hafiz Md. Hasan Babu · 2020
This chapter introduces a fault-tolerant reversible division circuit. In arithmetic and algebraic computation, the basic operations are addition, subtraction, multiplication, and division. It is a fundamental problem to find efficient algorithms for division, as it seems to be the most difficult of these basic operations. The chapter shows a method for binary floating-point division as well as an algorithm for binary floating-point division. The division method consists of four steps: First, it considers floating-point data and rounding. Second, it performs correctly rounded division. Third, it performs correct rounding from one-sided approximations. Finally, it calculates the result of the division operation. In order to design reversible fault-tolerant division circuit, reversible multiplexers, registers, parallel-in-parallel-out left-shift registers, D latch, rounding and normalization registers and parallel adder are required.
