Fastest Path to Production Silicon with World-Leading Performance, on Leading-Edge Technology

Pressure on today’s computing infrastructure is driving the need for specialized processing across cloud, AI, 5G, and networking markets. With Arm Neoverse Compute Subsystems (CSS), Arm delivers validated, performance-optimized compute on a leading-edge foundry process, so Arm’s infrastructure partners can focus scarce silicon design resources on building differentiated, market-customized solutions.

Features and Benefits

Fastest Path to Production Silicon

With Arm Neoverse Compute Subsystems (CSS), Arm delivers a proven, verified compute subsystem that can reduce risk, lower NRE, and accelerate CPU time to market by up to one year. Together with SystemReady SR compliance, Neoverse CSS helps enable a software ecosystem that just works.

Customizable, World-Class Performance

Neoverse CSS takes Arm Neoverse platform IP and optimizes it for performance, power, and area using a leading-edge foundry process. Customers can customize Neoverse CSS with on-chip or off-chip accelerators for performance-per-watt optimized specialized computing.
Leading Edge Technology

Neoverse CSS delivers the roadmap of Armv9 features and Neoverse technologies out of the box – Arm Confidential Compute, AMBA CHI C2C, Arm Scalable Matrix Extensions, and more. Neoverse CSS also provides system management, power management, and platform software support.

Neoverse CSS Customer Value

Arm Neoverse CSS delivers customer value by performing more of the non-differentiated but necessary steps in bringing customized silicon to market. Neoverse CSS customers have reported significant benefits from this unique engagement with Arm, including:
