The current process technologies are able to integrate billions of transistors on a single chip and the density of integration is even increasing. To effectively utilize the continuous increase in on-chip area there is a trend towards integration of more and more processing elements e.g. general-purpose processors, DSPs, memories, ASICs, reconfigurable hardware and custom hardware onto a single chip. The continuous increasing demand in number of on-chip resources has lead the SoC researchers to design scalable, modular and efficient on-chip communication infrastructures known as networks on...
