Advancements in the field of chip fabrication has facilitated in integrating more number of transistors in a given area which has lead to an era of multi-core processors. Future multi-core chips or chip multiprocessors (CMPs) will have hundreds of heterogeneous components including processing engines, custom logic, GPU units, programmable fabrics and distributed memory. Such multi-core chips are expected to run varied multiple parallel workloads simultaneously. Hence, different communicating cores will require different bandwidths leading to the necessity of a heterogeneous Network-on-Chip (NoC) architecture. Simply over-provisioning for performance will invariably result in loss of power efficiency. On the other hand, recent research has shown that photonic interconnects are capable of achieving high-bandwidth and energy-efficient on-chip data transfer. In this paper we propose a dynamic heterogeneous photonic NoC (d-HetPNOC) architecture with dynamic bandwidth allocation to achieve better performance and energy-efficiency compared to a homogeneous photonic NoC architecture with the same aggregate data bandwidth.
