摘要

In a routing design of a voltage-frequency-island (VFI) network-on-chip (NoC), VFI NoC provides a path between a plurality of cores, a plurality of routers matched by the cores, , Wherein a plurality of cores and routers are zoned into two or more zones each using a different voltage and frequency, and the consumed energy value per bit per packet of data according to the traffic characteristic of any application and a different Calculating an optimal path having a minimum energy consumption value based on the additional energy consumption by the communication between the zones, calculating at least one bypass path for each router assuming a failure for each link passing through the optimal path, And stores at least one bypass route in the routing table of the router.
