Abstract EN
Network-on-Chip (NoC) is one of critical communication architectures for future many-core systems.
As technology is continually scaling down, on-chip network meets the increasing leakage power crisis.
As a leakage power mitigation technique, power-gating can be utilized in on-chip network to solve the crisis.
However, the network performance is severely affected by the disconnection in the conventional power-gated NoC.
In this paper, we propose a novel partial power-gating approach to improve the performance in the power-gated NoC.
The approach mainly involves a direction-slicing scheme, an improved routing algorithm, and a deadlock recovery mechanism.
In the synthetic traffic simulation, the proposed design shows favorable power-efficiency at low-load range and achieves better performance than the conventional power-gated one.
For the application trace simulation, the design in the mesh/torus network consumes 15.2%/18.9% more power on average, whereas it can averagely obtain 45.0%/28.7% performance improvement compared with the conventional power-gated design.
On balance, the proposed design with partial power-gating has a better tradeoff between performance and power-efficiency.
