Ephedrine QoS: An Antidote to Slow, Congested, Bufferless NoCs

Table 1

Interval-based QBLESS congestion control.

Each node	Global controller
(1) Dynamically throttle according to global controller information from previous quantum; (2) Monitor IPF and starvation throughout this quantum	(1) Collect node measurements from previous quantum; (2) Identify congestion spots; (3) Calculate throttling rate for next quantum; (4) Broadcast throttling rate; (5) Wait for next quantum and repeat
