The NoC interconnect is the SoC architecture.
In my first article of this series about interconnect design, I explained why on-chip communication has become central to a system-on-chip (SoC) architecture. These architectural decisions determine bandwidth, throughput, quality-of-service (QoS), power usage, safety, and cost. Here, the difference between a world-class achievement and a shortcoming starts with the communication architecture choice.
