دانلود A Novel Approach to Design Decimal to BCD Encoder with Reversible Logic

Abstract

Encoder circuits are vital component of an electronic computer system. Encoders are generally used for the conversion of a 2n bit number into the n bit number. Applications of encoders can be visualized as keyboard encoder on widespread use. Design of an optimized encoder circuit with the concept of reversible logic is the main  outcome  of  this  research  paper.  The  concept  of  reversible  logic  has  become  burgeoning  tool  for  the  designing  of  efficient  digital  circuits  with  low  power  dissipation.  This  paper  provides  a  possible  approaches  to  design  a  decimal  to  BCD  encoder  using  reversible logic gates. Optimization of the circuit has been explored on the basis of minimization of some performance parameters such as  number  of  reversible  logic  gates  used  in  the  designing,  garbage  outputs generated during the operation of the circuit and quantum cost of the circuit.
