In chip-multiprocessors (CMPs) the network-on-chip (NoC) carries cache coherence and data messages. These messages may be classified into critical and non-critical messages. Hence, instead of having one interconnect plane to serve all traffic, power can be saved if the NoC is split into two planes: a fast plane dedicated to the critical messages and a slower, more power-efficient plane dedicated only to the non-critical messages. This split, however, can be beneficial to save energy only if… CONTINUE READING
