Deep Vision licenses SiFive Intelligence X280 processor to deliver greater flexibility and AI inference pre-processing for many markets

SAN MATEO, Calif., — (BUSINESS WIRE) — January 17, 2022 — SiFive, Inc., the founder and leader of RISC-V computing, today announced that Deep Vision will integrate SiFive RISC-V processor IP into its next-generation inference accelerators to enable more comprehensive computer vision and voice in edge devices. Specifically, Deep Vision will license SiFive Intelligence™ X280 and SiFive Essential™ S7 processor IP to enhance the flexibility and functionality of their products to better support customers building applications for markets like smart city, smart retail, automotive, and industrial.

SemiCo Research¹ estimates the AI SoC market to reach 25B units by 2027, with revenue reaching $291B, with RISC-V-based AI SoCs unit CAGR of 73.6% by 2027. The SiFive Intelligence X280 processor enables Deep Vision accelerators to offer broader neural network model support and optimizations for floating-point operations. SiFive Intelligence processors feature SiFive Intelligence Extensions to support TensorFlow Lite and a broad range of AI/ML data types, including BFLOAT16. The flexibility and programmability of the SiFive Intelligence X280 processor as an application class AI processor extends the proven capabilities and performance of Deep Vision accelerators to rapidly support new and evolving AI inference models in hardware, as well as AI pre-processing tasks such as image scaling, color conversion, and white noise subtraction.

The SiFive Essential S7 processor features real-time, deterministic processing capabilities to enable command and control applications within a heterogeneous compute cluster, alongside other SiFive RISC-V processors. Ideally suited to latency-sensitive edge compute applications, the SiFive Essential S7 processor architecture features enhanced security and real-time determinism while offering area-efficient performance-per-watt.

“We are excited to increase the flexibility and capabilities of our next-generation AI accelerators with the performance and features of SiFive RISC-V processors,” said Ravi Annavajjhala, CEO, Deep Vision. “We can address a broader range of AI use cases and applications, thanks to SiFive Intelligence and SiFive Essential processors, as well as accelerate customer adoption of our solutions. With the AI market evolving rapidly, flexibility and more comprehensive AI support are crucial for success.”

“Combining the strengths of SiFive Intelligence RISC-V processors with Deep Vision inference accelerators is a natural way to quickly and efficiently build new hardware for the rapidly evolving AI processor market,” said Dr. Yunsup Lee, CTO and co-founder, SiFive. “The requirements for modern AI are well matched to SiFive Intelligence Extensions and RISC-V Vectors as implemented in the SiFive Intelligence X280. With our industry-leading RISC-V processor IP portfolio, SiFive is perfectly positioned to enable AI companies who seek to quickly develop market-focused platforms.”

Recently, SiFive introduced the SiFive 21G3 update with enhancements and performance improvements for a wide range of products, including support for the recently ratified RISC-V Vector and Hypervisor specifications. For more information, please read our blog covering recent announcements, here.
