A 2 Tb/s 6 $\,\times\,$ 4 Mesh Network for a Single-Chip Cloud Computer With DVFS in 45 nm CMOS

A packet-switched 6 × 4 2-D mesh network providing 2 Tb/s of bisectional bandwidth with a per-hop latency of 4-cycles, forms the high performance communication fabric for a Single-Chip Cloud Computer (SCC) with 48 Pentium™ class IA-32 cores. The fabric operates on an independent power supply and frequency domain. The router micro-architecture achieves over 90% network utilization by effective use ...
