Connecting the Dots: Why RISC-V System Design Is Entering a New Era

RISC-V is transitioning towards a system-level design focus, emphasizing connectivity, integration, and security as crucial for scalability. Data movement, not compute power, is now the primary bottleneck in system performance, especially in GPU-class SoCs. The rise of chiplets and multi-die architectures adds complexity, making connectivity a central architectural pillar. RISC-V's flexibility poses integration challenges, necessitating a robust interconnect strategy to avoid fragmentation. Collaboration and ecosystem-level solutions are key to addressing challenges in automotive, AI, and hardware security, highlighting the need for a system-centric design approach for successful RISC-V-based SoCs.
