Arm's Chiplet System Architecture Spec Opens Up a New Era of Silicon Design
Arm has released the first public specification for its Chiplet System Architecture (CSA), with over 60 companies already engaged. The CSA addresses the growing demand for custom silicon and the associated high costs and complexities of monolithic chip production by enabling the reuse of specialized chiplets to create multiple custom systems-on-chips (SoCs) with better performance and lower power consumption. This standardization effort, developed collaboratively with the ecosystem, ensures interoperability and reusability, accelerating innovation and reducing fragmentation. Early adopters are already leveraging the CSA to build solutions tailored for diverse AI workloads. Alphawave Semi, for instance, combines Arm Neoverse CSS-powered chiplets with proprietary I/O dies to create performant chips for various markets. Meanwhile, ADTechnology, Samsung Foundry, and Rebellions are collaborating with Arm on an AI CPU chiplet platform for large-scale AI training and inference, boasting a 2-3x efficiency advantage for GenAI workloads.
