Why SoC Interconnects Have Outgrown the Bus

This technical white paper explores why modern AI, automotive, and chiplet-based SoCs are outgrowing traditional interconnects and how advanced NoC architectures and coherent subsystem IP can address the industry’s next-generation scalability, safety, and performance challenges. The shared-bus and crossbar interconnects that served the SoC industry for two decades are running out of room. AI accelerator workloads demand heterogeneous coherency at agent counts where broadcast-snoop fabrics collap
