System on Chips are not containing IP cores only and traditional methods for communication such as bus are not suitable solution for future System on Chips. That is impossible to send signals from one end to another end within a clock cycle. Problems such as global wire delay and global synchronization will limit users. Network on Chip (NoC) is one solution for designing communication among components in the SoC circuits with several billion transistors that will reach the market in approximately 5-10 years from now. Different topologies having various advantages according to their applications. This paper present brief idea about topologies depending on parameter.
