Abstract
Graded throttling for network-on-chip traffic, including: calculating, by an agent of a network-on-chip, a number of outstanding transactions issued by the agent; determining that the number of outstanding transactions meets a threshold; and implementing, by the agent, in response to the number of outstanding transactions meeting the threshold, a traffic throttling policy.
Claims20
A chip with graded throttling for network-on-chip traffic, the chip comprising:
- a network-on-chip;
- a plurality of agents communicatively coupled to the network-on-chip;
- a detector circuit coupled to one or more of the plurality of agents, the detector circuit configured to determine that a predefined condition is met;
- and
- a mediator circuit coupled to the detector circuit and to one or more agents of the plurality of agents, the mediator circuit configured to:
- receive a signal that the predefined condition is met from the detector circuit;
- and
- transmit, in response to the signal from the detector circuit, an indication to implement a traffic throttling policy to the one or more agents of the plurality of agents using an unrouted signal path between the mediator circuit and the one or more agents of the plurality of agents.

A method of graded throttling for network-on-chip traffic, the method comprising:
- determining, by a detector circuit of a network-on-chip that a predefined condition is met;
- sending a signal from the detector circuit to a mediator circuit;
- and
- sending, in response to the signal, an indication to implement a traffic throttling policy from the mediator circuit to each of a plurality of agents using an unrouted signal path between the mediator circuit and each of the plurality of agents.
