دانلود A Survey on Different Topologies, Switching Techniques and Routing Algorithms for A Network on Chip

Abstract

Network on Chip (NoC) is a new paradigm for making interconnections w ithin System on Chip (SoC) system. With the increasing chip integration and  decreasing feature size  the SoC does not  meet the  challenges  of  the  new  process  technologies  .The  challenges  include    complexity and    increased  delay  in  communication  and  also  the  bus  contention  and  arbitration    slows down  the  data  movement  which  degrades  the  overall  performance  of  Soc.  Noc  is  a  design platform that can meet these challenges to a great extend. In the network design of the NoC the most  essential  things  are  a  network  topology  and  a  routing  algorithm.  Routers  route  the packets  based  on  the  algorithm  that  they  use.  In  this  paper  a  study  of    the  different  routing algorithms for network on chip is presented that can cope up with above mentioned problems arising  in  SoC.  The  routing  algorithm  of  a  given  NoC  system  is  measured  with  respect  to performance metrics such as  latency, throughput and load distribution.  Here we are about to deal with the different topologies ,switching techniques ,performance analysis of NoC  routing algorithms  such as X Y routing algorithm, OE routing algorithm and DyAD routing algorithm.
