Network on Chip :-

There are two terms widely used in the electronic industry to come out as a full fledged IC design.
The one of these is SOC  and the other is NOC.


The NOC is the newly introduced concept on the basis of which the communication interfaces between different communication media is developed especially for intellectual property blocks which are normally used on VLSI chips.

below is the diagram which illustrates the architecture of network on chip

 
The implementation of Network On chip involves following 


1. NoC applies networking  theory and methods to on-chip communication and brings notable improvements over conventional bus and crossbar interconnections. NoC improves the scalability of SoCs, and the power efficiency of complex SoCs compared to other designs. 


2.Like the networking of computers, NoC provides an efficient means to manage communications among any collection of distributed systems, which in the case of a complex SoC can be individual IP blocks and/or clusters of functionality that all must communicate with each other.
