Overview

The latest generation SiFive Performance™ P600-Series processors are the highest performance commercially licensable RISC-V processors.

The P670 vector application processor features a thirteen-stage, four-issue, out-of-order pipeline and offers best-in-class performance, with >50% uplift over the SiFive Performance P550, while maintaining a significant performance-per-area advantage compared to the Arm® Cortex®-A78.

For applications that don't require vector compute, or for more area-constrained markets, the P650 offers similar performance levels in a smaller area footprint.

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.

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.

Pie: Pooling CPU Memory for LLM Inference

Pie maintains low computation latency, high throughput, and high elasticity. Our experimental evaluation demonstrates that Pie achieves optimal swapping policy during cache warmup and effectively balances increased memory capacity with negligible impact on computation. With its extended capacity, Pie outperforms vLLM by up to 1.9X in throughput and 2X in latency. Additionally, Pie can reduce GPU memory usage by up to 1.67X while maintaining the same performance. Compared to FlexGen, an offline profiling-based swapping solution, Pie achieves magnitudes lower latency and 9.4X higher throughput.
