The invention discloses a DQN-based network-on-
chip arbitration intelligent optimization method, and belongs to the field of computer
system structure network-on-
chip interconnection. In an application task execution process, data
packet arrival information of an input port of an on-
chip network router is collected in real time, time density characteristics and fluctuation characteristics reflecting
traffic intensity and
time sequence fluctuation characteristics are extracted, and operation state information such as a
router cache
utilization rate, a port competition degree and an
injection rate is combined, so that the data
packet arrival information of the input port of the on-chip
network router is obtained. And multi-dimensional state description of the
router is constructed. A plurality of candidate basic arbitration strategies are preset, a deep Q network
reinforcement learning model is adopted, and dynamic selection is carried out among the candidate arbitration strategies according to real-time
router state information, so that a better arbitration strategy is selected under the constraint of communication
delay and
power consumption. Through continuous
interactive learning with a network-on-chip operation environment, the method can adaptively match arbitration strategies under different load and flow scenes, effectively reduce communication
delay and
tail delay, and improve communication efficiency and energy efficiency of the network-on-chip.
