Using Segmentation to Improve Schedulability of RRA-based NoCs with Mixed Traffic

Publication Type:

Conference/Workshop Paper

Venue:

22nd Asia and South Pacific Design Automation Conference


Abstract

Network-on-Chip (NoC) is the interconnect of choice for many- core processors and system-on-chips in general. Most of the exist- ing NoC designs focus on the performance with respect to average throughput, which makes them less applicable for real-time appli- cations especially when applications have hard timing requirements on the worst-case scenarios. In this paper, we focus on a Round- Robin Arbitration (RRA) based wormhole-switched NoC which is a common architecture used in most of the existing implementa- tions. We propose a novel segmentation algorithm targeting RRA- based NoCs in order to improve the schedulability of real-time traf- fic without modifying the hardware architecture. Additionally, we also address the problem of transmitting both real-time traffic and best-effort traffic in the same NoC. The proposed solutions aim to provide timing guarantees to real-time traffic and achieve low la- tency for best-effort traffic. According to the evaluation results, the proposed segmentation solution can significantly improve the schedulability of the whole network.
