Network-on-Chip

Network-on-Chip(NoC) has become default communication paradigm in System-on-Chip (SoC). The research challenges involve low power, high performance, security and scalability aspects of NoC design beyond current state of art in the industries. During the last decade, the researchers in the lab have contributed their works in the following topics.

  • Interconnect Modelling
  • Core-Network Interface Architecture
  • Concurrent online testing
  • Low Power NoC Design
  • Virtual Prototypes

However, the demand for bandwidth increases exponentially with the rise in number of cores of CMPs. Traditional metallic interconnects can’t offer such an enormous bandwidth considering the power limits. On the contrary, photonic interconnects provides extremely high data rate with least power consumption. Photonic Network-on-Chip(PNoC) is the next generation on-chip communication paradigm for CMPs, which uses photonic interconnects as its building blocks. The group currently investigates the following topics

  • Adaptive multiplexing in PNoC
  • Multi-layer PNoC design
  • Thermal management in PNoC
  • Reliability aware power management in photonic data centers.
