32-Bit & 64-Bit High Performance Processor - 9-Stage Pipeline, Dual-issue
900 Series processors include four different classes: N900 (32 bit), U900 (32 bit + MMU), NX900 (64 bit) and UX900 (64 bit + MMU).
Overview
900 Series processors include four different classes: N900 (32 bit), U900 (32 bit + MMU), NX900 (64 bit) and UX900 (64 bit + MMU). With MMU, UX900 supports heavyload operating systems such as Linux. 900 Series can be applied to edge computing, data center, networking, etc.
600-SMP(multi-core) is the configurable version of 600 Series support symmetric multi-processor (SMP) configuration.

Announcing Arm AGI CPU: The silicon foundation for the agentic AI cloud era
For the first time in our more than 35-year history, Arm is delivering its own silicon products – extending the Arm Neoverse platform beyond IP and Arm Compute Subsystems (CSS) to give customers greater choice in how they deploy Arm compute – from building custom silicon to integrating platform-level solutions or deploying Arm-designed processors.
ChiPy®: Bridge Neural Networks and C++ on Silicon — Full Inference Pipelines with Zero CPU Round-Trips
The ChiPy DSL is Quadric's Python framework for building complete on-chip pipelines. Using YOLOX-M as a case study, we show how backbone inference, box decoding, and NMS run entirely on the Chimera GPNPU — no host CPU intervention, no DDR round-trips, just Python compiled to silicon.
Unleashing Leading On-Device AI Performance and Efficiency with New Arm C1 CPU Cluster
As part of the new Arm Lumex compute subsystem (CSS) platform, the Arm C1 CPU cluster – the first built on the Armv9.3 architecture – is the next evolution of our highest performing CPU cluster for consumer devices, designed to unleash the full potential of on-device AI and elevate the user experience.
Encarsia: Evaluating CPU Fuzzers via Automatic Bug Injection
Hardware fuzzing has recently gained momentum with many discovered bugs in open-source RISC-V CPU designs. Comparing the effectiveness of different hardware fuzzers, however, remains a challenge: each fuzzer optimizes for a different metric and is demonstrated on different CPU designs.
