Carbon nanotubes as interconnect for next generation network on chip

Multi-core processors provide better performance when compared with their single-core equivalent. Recently, Networks-on-Chip (NoC) have been emerged as a communication methodology for multi core chips. Network-on-Chip uses packet based communication for establishing a communication path between multiple cores connected via interconnects. Clock frequency, energy consumption and chip size are largely determined by these interconnects. According to the International Technology Roadmap for Semiconductors (ITRS), in the next five years up to 80% of microprocessor power will be consumed by interconnects. In the sub 100nm scaling range, interconnect behavior limits the performance and correctness of VLSI systems. The performance of copper interconnects tend to get reduced in the sub 100nm range and hence we need to examine for other interconnect
