Original Abstract Submitted

an apparatus includes a system-on-chip that includes a plurality of agents configured to generate data transactions, a communication network configured to transfer transactions between two or more of the agents, a plurality of network switches, and a bandwidth regulation circuit. the network switching circuits may be coupled to the agents and to the network. one of the network switches may be configured to estimate a bandwidth need for transactions to be sent via the network switch in an upcoming window. the bandwidth regulation circuit may be configured to moderate power consumption of the network by determining a bandwidth budget using a network power budget for the upcoming time window, and determining a global bandwidth forecast using estimated bandwidth needs received from the network switches. the bandwidth regulation circuit may also be configured to allocate, using the global bandwidth forecast, the bandwidth budget among the network switches.
