SiFive 2nd Generation Intelligence Family Introduction

In this video, SiFive Co-Founder and Chief Architect Krste Asanović presents the second generation of the SiFive Intelligence Family, a suite of RISC-V-based AI accelerator IP cores. These cores support efficient edge AI acceleration across applications from low-power far-edge devices to cloud-scale systems. Built on the open RISC-V standard with custom extensions, the family ensures compatibility with the RVA23 profile, enabling seamless integration with custom accelerators for AI inference, large language models, and related workloads. The second generation delivers up to 2x throughput improvements vs. competition, single-cycle AI instructions, and direct-to-core interfaces such as SSCI and VCIX for enhanced scalability. Supported by more than 40 first-generation design wins, these cores facilitate standalone or hybrid deployments in SoC designs.
