Highly Scalable Mesh for Large Core Count Automotive Designs Including Chiplets

The Arm Neoverse CMN S3AE coherent mesh network is designed to enable scalable performance for automotive applications, central compute, and machine learning (ML) workloads. The highly scalable mesh is optimized for Armv9.2, Armv9, Armv8-A processors, multichip configurations, and CXL attached devices. It forms the foundation for both SoCs and chiplets. It can be customized across a wide range of performance points.

Features and Benefits

High-Performance, Scalable Coherent Mesh

The scalable mesh network can be customized to meet system performance and area requirements. The native AMBA 5 CHI network provides high-frequency, non-blocking data transfers between compute, accelerator, and IO to shared memory resources.

Safety Capability

CMN S3AE is designed to enable ASIL B use cases, with a range of safety features including ECC & parity mechanisms and other techniques to achieve diagnostic coverage goals.

AMBA CHI Chip to Chip

CMN S3AE forms the foundation for chiplet-based designs. Enabling the key chiplet capabilities needed for next-generation chiplet applications. CMN S3AE enables chiplet designs with same as ease and performance as monolithic designs.
