1. A system for network-on-chip power management, comprising:
a primary network-on-chip comprises multiple components, each component having a power controller;
characterized by
a secondary network-on-chip comprises a secondary network-on-chip master node and a plurality of secondary network-on-chip nodes connected thereto, the plurality of secondary network-on-chip nodes associated to the components of the primary network-on-chip for power managing individual and link components of the primary network-on-chip; and
a power management unit connected to the secondary network-on-chip master node, configured to polling status registers of the components of the primary network-on-chip for accessing power states of each component, accessing routing information of the components of the primary network-on-chip and sending request to the secondary network-on-chip nodes for powering on or off the associated components of the primary network-chip through the power controller.
