Noc-based thread synchronization in a custom manycore system

Abstract

This workshop paper presents an efficient hardware support for thread synchronization in a customized manycore system developed within the MANGO H2020 project. The solution relies on a distributed master and on a lightweight control unit on the core side, using hardware-level messages and thus avoiding memory accesses. It supports multiple barriers for different application kernels executed simultaneously. The results for different NoC sizes provide indications about the reduced synchronization times and the area overheads incurred by our solution.
