A 5-Ghz Mesh Interconnect For A Teraflops Processor

A multicore processor in 65-nm technology with 80 single-precision, floating point 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.
