Segment Gating for Static Energy Reduction in Networks-on-Chip

Chip MultiProcessors (CMPs) have emerged as a primary vehicle for overcoming the limitations of uniprocessor scaling, with power constraints now representing a key factor of CMP design. Recent studies have shown that the on-Chip interconnection Network (NOC) can consume as much as 36% of overall chip power. To date, researchers have employed several techniques to reduce power consumption in the network, including the use of on/off links by means of power gating. However, many of these techniques target dynamic power, and those that consider static power focus exclusively on flit buffers.
