Performance analysis of Network-on-Chip (NoC) architectures has traditionally been done by assuming dumb slaves that return responses either immediately or with a fixed delay. Typical SoC architectures incorporating a NoC have high bandwidth communication to an external DRAM. In effect, the DRAM creates the performance bottleneck of the system.
This paper provides a set of necessary parameters that can be used to generate a highly abstracted DRAM controller and memory. The objective is to keep the abstraction level high enough to make development easy, and at the same time, capture the critical parameters that significantly influence the performance of the system.
