Title: Catnap (a short, light sleep): Năng lượng tỉ lệ với đa NOC

Main contribution:

• Catnap architecture consists of synergistic subnet selection and powergating policies.
• Catnap maximizes the number of consecutive idle cycles in a router, while avoiding performance loss due to overloading a subnet.

Result:

• Average network power could be 44% lower than a bandwidth equivalent single-network design
• An average performance cost of about 5%

Question:

• Why the title mentions energy but the result only considers power and cost.

Intro

An on-chip network is energy-proportional if it consumes power that is proportional to the network demand and has insignificant impact on network latency.

Motivation: a few phases that consume peak network bandwidth, and other computationally intensive phases that inject few packets into the network. Thus, to build an energy proportional many-core processor, it is important to design energy proportional on-chip networks.
