As the multicast communication is utilized commonly in various parallel applications, the performance can be significantly improved by supporting multicast operations at the hardware level. In this paper, we define several factors of efficiency for unicast/multicast communication such as average of unicast latency, average of maximum multicast latency and level of parallelism in 3D mesh NoCs. Then,...
Nowadays, in MPSoCs and NoCs, multicast protocol is significantly used for many parallel applications such as cache coherency in distributed shared-memory architectures, clock synchronization, replication, or barrier synchronization. Among several multicast schemes proposed in on chip interconnection networks, path-based multicast scheme has been proven to be more efficient than the tree-based, and...
A novel routing algorithm, named balanced adaptive routing protocol (BARP), is proposed for NoCs to provide adaptive routing and ensure deadlock-free and livelock-free routing at the same time. By evenly distributing input packets of a router among all its shortest path output ports, a novel adaptive routing protocol for avoiding congestion condition emerges. It is observed that BARP can achieve better...
