Contribution
It presents a novel analytical method to compute latency bounds in routerless networks-on-chip for real-time systems, which was not previously available.
Findings
Routerless networks can meet real-time latency guarantees under certain conditions.
The proposed framework effectively compares routerless and traditional networks.
Routerless networks show promising performance for real-time multiprocessor communication.
Abstract
This paper considers the use of routerless networks-on-chip as an alternative on-chip interconnect for multiprocessor systems requiring hard real-time guarantees for inter-processor communication. It presents a novel analytical framework that can provide latency upper bounds to real-time packet flows sent over routerless networks-on-chip, and it uses that framework to evaluate the ability of such networks to provide real-time guarantees. Extensive comparative analysis is provided, considering different architectures for routerless networks and a state-of-the-art wormhole network based on priority-preemptive routers as a baseline.
