HiFive Unmatched RISC-V computer board is now shipping

At first glance, the HiFive Unmatched from SiFive looks like just another mini ITX computer motherboard. But rather than an x86 chip, this system is powered by RISC-V processor. First introduced last fall, the board is aimed at developers rather than the general public, and with a $665 price tag, it’s a lot more expensive than some other RISC-V development boards. But the HiFive Unmatched is also one of the most powerful products in this emerging category to date, thanks to SiFive’s FU740 processor.

Moore’s Law is Dead: So, Let’s Talk About the Future of SoCs

By now, you’ve likely heard someone tell you: Moore’s Law is dead. To be sure, it is worthwhile to point out that the design aspect of Moore’s Law is – in most circumstances – very much alive. There are still techniques to be discovered to make the transistors smaller, for them to work faster, and to still put more of them in the same footprint. Rather, it is the economics behind Moore’s Law that has clearly reached its endpoint. Chips might continue to get smaller and faster. But if the economics mean that almost no one can afford to buy them, where exactly are we headed?

SiFive FE310: Setting The RISC Free

It is out of this that SiFive began. SiFive was founded by the creators of the first commercially successful open RISC architecture, known as RISC-V. RISC-V was developed at Berkeley, fittingly, in 2010 and was designed to be a truly useful, general purpose RISC processor, easy to design with, easy to code for, and with enough features to be commercially useful, not limited to the classroom. It is called the RISC-V because it is the fifth RISC design developed at Berkeley, RISC I and RISC II being designed in 1981, followed by SOAR (Smalltalk On A RISC) in 1984 and SPUR (Symbolic Processing Using RISC) in 1988. RISC-V has already proved to be a success, it is licensed freely, and in a way (BSD license) that allows products that use it to be either open, or proprietary. One of the more well known users is Nvidia, which announced they are replacing their own proprietary FALCON processors (used in their GPUs and Tegra processors) with RISC-V. Samsung, Qualcomm, and others are already using RISC-V. These cores are often so deeply embedded that their existence goes without mention, but they are there, working in the background to make whatever tech needs to work, work.

A Patient Disciple of RISC-V, SiFive Starts Selling Cores

Last year, SiFive went fishing for engineers willing to test out chips based on the RISC-V instruction set, releasing a basic core called Rocket that anyone could download and modify. But now the company, whose founders invented RISC-V, is using richer bait for more ambitious customers. Last week, SiFive started selling two embedded cores under the brand Coreplex, with applications ranging from wearables to servers. The company is aiming to lower the bar for engineers trained on Intel or ARM instruction sets to take RISC-V for a spin, when few companies appear to be turned off by the inflexibility or licensing fees of rival technology.

"We believe we can do it cheaper, quicker and more predictably than anyone else.” They have also been getting lots of calls to help with designs. Growing the RISC-V ecosystem is a big opportunity. The traditional semiconductor business models take a lot of resources, so you have to pick the winners. But there aren't any $1B sockets anymore, so you can't easily pick the winners.

RISC-V opens for business with SiFive Freedom

When we talk about open source, free usually comes in the context of “freedom”, not as in “free beer”, and open IP often serves as a base layer of value add for commercialization. The creators of the RISC-V instruction set, now working at startup SiFive, have released specifications for their aptly-named Freedom processor IP cores looking for "enablement of great ideas".

This New Chip Startup Wants To Bring Open Source To A Stagnant Industry

Open source has taken off in the software world. RISC-V maybe has the opportunity to bring open source to the rigid chip industry. Born out of university research, RISC-V is a chip architecture that lets developers freely change and customize chip designs without having to pay for expensive licenses or royalty fees.

Backers of Open Source Chips Launch Startup

A group of university researchers recently attracted attention by applying principles of open-source software to computer chips. Now they’re turning the concept into a company. A San Francisco-based startup called SiFive on Monday is announcing plans to develop and sell chips based on a technology called RISC-V. The tech includes a set of instructions that define the functions of a microprocessor, which can serve as a starting point for designing a chip.

Will Open-Source Work For Chips?

Open source is getting a second look by the semiconductor industry, driven by the high cost of design at complex nodes along with fragmentation in end markets, which increasingly means that one size or approach no longer fits all.

RISC-V—Instruction Sets Want to Be Free

I had never heard of RISC-V (pronounced five, not vee) until earlier this year when there was a presentation about it at EDPS in Monterey. I immediately texted the daughter of a friend of mine who is a CS major at Berkeley where it originated and she gave me a bit more background.

Alternative To X86, Arm Architectures?

Software developed by professors and graduate students from the University of California at Berkeley? That will never fly in the semiconductor industry, right?

Can Open Source Hardware Crack Semiconductor Industry Economics?

The running joke is that when a headline begs a question, the answer is, quite simply, “No.” However, when the question is multi-layered, wrought with dependencies that stretch across an entire supply chain, user bases, and device range, and across companies in the throes of their own economic and production uncertainties, a much more nuanced answer is required.

RISC-V Offers Simple, Modular ISA

RISC-V is a new general-purpose instruction-set architecture (ISA) that’s BSD licensed, extensible, and royalty free. It’s clean and modular with a 32-, 64-, or 128-bit integer base and various optional extensions (e.g., floating point). RISC-V is easier to implement than some alternatives—minimal RISC-V cores are roughly half the size of equivalent ARM cores—and the ISA has already gathered some support from the semiconductor industry.

RISC-V Inching Closer to Reality at Scale

Back in the early 1990s, the common view was that there was little money to be made in the business of open source. As the wave of Linux distributions rolled forth, however, that was quickly disproven, setting the decades-long chain of companies that have secured their footing, funding, and futures on the back of open software.
