Coupling TDM NoC and DRAM Controller for Cost and Performance Optimization of Real-Time Systems

Existing memory subsystems and TDM NoCs for real-time systems are optimized independently in terms of cost and performance by configuring their arbiters according to the bandwidth and/or latency requirements of their clients. However, when they are used in conjunction, and run in different clock domains, i.e. they are decoupled; there exists no structured methodology to select the NoC interface width and operating frequency for minimizing area and/or power consumption. Moreover, the multiple arbitration points, one in the NoC and the other in the memory subsystem, introduce additional overhead in the worst-case guaranteed latency.
