Abstract

This paper presents a novel scheduling approach that efficiently schedules the computational and the communicational resources of a Software-Defined Photonic Network-on-Chip (SD-PNoC) Architecture designed for high-performance real-time systems. The proposed scheduling approach extends the conventional cyclic executive scheduling algorithm from the one that schedules solely the computational resources into a general one that schedules both the computational and the communicational resources together in a synchronized manner. The proposed SD-PNoC architecture employs Software Defined Network (SDN) approach by using application specific conflict-free and contention-free communication patterns to solve the routing and wavelength assignment (RWA) problem exists in photonic networks. The implementations of the collective communication primitives such as broadcast and all-to-broadcast are also presented to demonstrate the system as a whole.
