On-Chip Networks Optimize Shared Memory For Multicore SoCs

Why increasing core counts and newer DRAMs impact external DRAM access and what to do about it.


Performance of multicore SoCs is often dominated by external DRAM access, particularly in digital consumer devices running high quality video and graphics applications. Increasing core counts and newer DRAMs make the problems much more difficult. This article covers optimization of the on-chip network and memory system to achieve the required system throughput.
