摘要：To day's chip- level multipro cesso rs (CMPs) feature up to a hundred discrete cores, and wit h increasing levels o f integration, CMPs with hundreds o f co res, cache tiles, and specia lized accelerators are anticipat ed in the near future. In t h i s p a p e r , we p r o p o se a n d e v a l u a t e technologies to enable networks-on-chip (NOCs) to support a t housand connected co mponents (Kilo-NOC) with high area a nd energ y efficiency, goo d perfo rmance, and strong quality-of- service (QOS) guarantees. Our a nalysis shows that QOS suppo rt burdens t he network with hig h area and energy cost s. In respo nse, we propose a new light weight topology-aware QOS architect ure that pro vides service guarantees for applications such as co nsolidat ed servers on CMPs and real-t ime SOCs. U nlike prior NOC qualit y-of-service pro posals which require QOS sup-po rt at every network node, our scheme rest ricts t he extent o f ha rdware support to po rtio ns o f the die, reducing router complexit y in the rest of the chip. We furt her impro ve net -work area- and energ y- efficiency through a novel flow cont rol mechanism that enables a sing le-network, low-co st elast ic buffer imp lementatio n. To gether, these techniques yield a hetero geneo us Kilo - NOC architecture that co nsumes 45% less area and 29% less po wer than a state-o f-t he-art QOS- enabled NOC wit ho ut these features
