This paper introduces PASTIS, a novel photonic arbitration protocol based on a scalable token injection scheme, and ring-based nanophotonic technology. It aims at connecting together processors and memories in many-core computer systems by means of a ring topology. The main strength of PASTIS lays in the fact that it uses photonic components exclusively, that is, routing does not require any electronics. In this work, we compare it with an hybrid opto-electronic protocol as presented in a related work. Simulations show that PASTIS performs better in terms of bandwidth, latency and energy consumption. Indeed, it is scalable as it can adapt its bandwith to the system's workload, thereby saving energy. Finally, we also study the opportunity of using reconfigurable rings. We determine that they almost halve the overall static power consumption.
