At the 2025 RISC-V Summit North America, Min Hsu, Staff Compiler Engineer at SiFive, presented on enhancing tiling support within SiFive’s AI/ML software stack for the RISC-V Vector-Matrix Extension (VME). This extension aims to boost matrix multiplication efficiency, a cornerstone of AI workloads. SiFive’s… Read More
In a presentation at the RISC-V Summit North America 2025, John Simpson, Senior Principal Architect at SiFive, delved into the evolving landscape of RISC-V extensions tailored for artificial intelligence and machine learning. RISC-V’s open architecture has fueled its adoption in AI/ML markets by allowing customization… Read More
RISC-V has emerged as a cornerstone of modern computing, offering an open-source alternative to proprietary designs like ARM and x86. Free from licensing fees and highly extensible, RISC-V powers everything from IoT devices to AI accelerators, with over 13 billion cores shipped globally. Annual RISC-V Summits, organized… Read More
SiFive, founded by the original creators of the RISC-V instruction set, has become the leading independent supplier of RISC-V processor IP. More than two billion devices already incorporate SiFive designs, ranging from camera controllers and SSDs to smartphones and automotive systems. The company no longer sells its own chips,… Read More
ARM’s Quiet Coup in DPUs
The datacenter is usually framed as a contest between CPUs (x86, ARM, RISC-V) and GPUs (NVIDIA, AMD, custom ASICs). But beneath those high-profile battles, another silent revolution has played out: ARM quietly displaced Intel and AMD in the Data Processing Unit (DPU) market.
DPUs — also called SmartNICs… Read More

Universal Chiplet Interconnect Express (UCIe) is an open specification that defines the interconnect between chiplets within a package. The objective is to enable an open chiplet ecosystem. Although the initial specification for UCIe was developed by Intel, a consortium was announced in March with Intel, AMD, Arm, Google,… Read More
Alphawave IP has agreed to acquire OpenFive, a SiFive business unit (formerly Open-Silicon) for $210m in cash. Having spent many years in the ASIC business which included working with Open-Silicon, Alphawave, and OpenFive here is my perspective on the acquisition:
This acquisition accomplishes two things: First it trims down… Read More
Exciting times for the semiconductor industry! Last week Intel announced a billion dollar fund to build a foundry ecosystem and today Intel announced they are acquiring foundry Tower Semiconductor for $5.6 billion dollars, WOW! Some people doubted Intel’s commitment to the foundry market this time. I think we can now put that… Read More
Operating systems and Instruction Set Architectures (ISA) can have long lifespans, and I’ve been an engineering user of many ISAs since the 1970s. For mobile devices I’ve followed the rise to popularity of the ARM architecture, and then more recently the RISC-V ISA which has successfully made the leap from university… Read More
