SiFive’s new AI accelerators speed up semiconductor firms’ time-to-market, delivering scalable, high-performance solutions for Edge, IoT, and data centers.
RISC-V chipmaker SiFive has announced a new series of AI accelerators for high-performance workloads.
The company says the Intelligence XM Series is its first IP to include a scalable matrix engine, designed to accelerate time-to-market for semiconductor companies building system-on-chip solutions for Edge, IoT, and data centers.
Based on the RISC-V open-source chip architecture, the Intelligence XM Series features four X-Core chips per cluster.
Each cluster can deliver 16 tera operations per second (INT8) or eight teraflops per second (BF16) per GHz. Each XM Series cluster has one TBp of sustained memory bandwidth, and it can access memory via a high-bandwidth port or a CHI port for coherent memory access.
Patrick Little, CEO of SiFive, said: “Many companies are seeing the benefits of an open processor standard while they race to keep up with the rapid pace of change with AI.
“AI plays to SiFive’s strengths with performance per watt and our unique ability to help customers customize their solutions. We’re already supplying our RISC-V solutions to five of the ‘Magnificent 7’ companies (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla), and as companies pivot to a ‘software first’ design strategy, we are working on new AI solutions with a wide variety of companies from automotive to data center and the intelligent Edge and IoT.”
SiFive also announced its intention to implement open-source references for its SiFive Kernel Library, which shows the company’s support for the wider RISC-V community.

“RISC-V was originally developed to efficiently support specialized computing engines, including mixed-precision operations,” said Krste Asanovic, SiFive founder and chief architect. “This, coupled with the inclusion of efficient vector instructions and the support of specialized AI extensions, are why many of the largest data center companies have already adopted RISC-V AI accelerators.”
Founded in California in 2015, SiFive is a fabless chip company that designs chips based on RISC-V, the open architecture that is increasingly seen as a useful alternative to the dominant x86 and Arm ecosystems.
In July, it launched SiFive Performance P870-D, a data center-focused processor for AI workloads.
