NoC Matters: Designing the Backbone of Next-Gen AI SoCs

The role of the network-on-chip (NoC) in modern AI SoC design has become crucial for system performance, power efficiency, and scalability, with data movement being a key factor. NoC architecture must be a primary design consideration due to the increasing complexity of AI-centric SoCs with diverse accelerators. Coherency models, specialized NoC hardware units, and physical floorplanning are essential aspects that impact system performance and efficiency. A structured methodology for NoC development, including traffic modeling, topology exploration, and physical partitioning, is crucial for successful implementation. Treating the NoC as a fundamental system-level design element is essential for achieving scalable performance and efficient power usage in complex AI SoCs.
