A 5-GHz Mesh Interconnect for a Teraflops Processor

A multicore processor in 65-Nm technology with 80 single-precision, floatingpoint cores delivers performance in excess of a Teraflops while consuming less than 100 W. A 2D on-die mesh interconnection network operating at 5 GHz provides the high-performance communication fabric to connect the cores. The network delivers a bisection bandwidth of 2.56 Terabits per second and a per hop fall-through latency of 1 nanosecond.
