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?

CPU Shack Museum — Jun 4, 2017
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.

Electronic Design — May 8, 2017
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.

SiFive is the first fabless provider of customized, open-source-enabled semiconductors. The RISC-V ISA has been central to our vision of enabling a whole new range of applications for everyone. In November 2016, we announced the availability of the Freedom Everywhere 310 (FE310) SoC, the industry's first commercially available chip based on RISC-V. Bringing the first commercially available SoC based on the RISC-V ISA is a huge milestone for the open-source hardware community.
Cadence — Jan 22, 2017
The SiFive business model is that lots of people are locked out of silicon. SiFive can do custom design and deliver chips. "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. The market is fragmented. SiFive wants to give everyone a chance. In a bit more detail, they will do a customer microcontroller platform and deliver 100 or so chips for under $100K.

One of the lessons learned years ago in the open-source Linux world is that free software isn’t always good enough. Consequently, being able to add commercial value around freeware can turn into a lucrative business.
Enter SiFive, a startup that has been building customized platforms based on the RISC-V CPU. Started by the creators of the RISC V instruction set architecture (ISA), the company’s stated goal is to shake up the economics of the chip industry.
Design News — Dec 15, 2016
Moore's Law is dead...just not in the way everyone thinks. Technological advances keep allowing chips to scale, but the economics are another story – particularly for smaller companies that can't afford chips in the volumes that the big chipmakers would like from their customers.
The solution, according to San Francisco-based startup, SiFive, is open-source hardware, specifically an architecture developed by the company's founders called RISC-V (pronounced “risk-five”). Done right SiFive, which was awarded Startup of the Year at the 2016 Creativity in Electronics (ACE) Awards, believes that RISC-V will do for the hardware industry what Linux has done for software.

Hackaday — Nov 28, 2016
The RISC-V ISA has seen an uptick in popularity as of late — almost as if there’s a conference going on right now — thanks to the fact that this instruction set is big-O Open. This openness allows anyone to build their own software and hardware. Of course, getting your hands on a RISC-V chip has until now, been a bit difficult. You could always go over to opencores, grab some VHDL, and run a RISC-V chip on an FPGA. Last week, OnChip released the RISC-V Open-V in real, tangible silicon.
EE Times — Nov 28, 2016
Startup SiFive started selling today a $59 Arduino board running its first RISC-V-based SoC and made open source RTL code available online for the chip. The news marks a milestone for a still nascent open source hardware movement.
Open source cores have been available previously but they tended to be academic efforts or lacked broad commercial support. The HiFive board is intended to drive demand for custom SoCs SiFive will design and comes with a growing pool of open source Linux variants and tools fed by an expanding foundation that maintains the RISC-V instruction set.

New Electronics — Sep 26, 2016
In their 2014 technical report for the University of California at Berkeley, Krste Asanovic and Professor David Patterson – who developed the concepts behind the SPARC architecture in the 1980s – argued that, while there are good commercial reasons for processor makers to maintain proprietary instruction sets, there is no good technical reason for users to adopt them. Their proposal was for an instruction set architecture (ISA) offered on a similar basis to open source software that could stimulate an ecosystem similar to that built around Linux.
As their proposal represented the fifth generation of RISC processor design, it was called RISC-V.

A couple of weeks ago I talked to Krste Asanović and Jack Kang of SiFive. One of their motivations is to bring the cost reduction that goes along with open-source software (and instruction sets!) to the hardware world. There is an increasing move in this direction as companies like Facebook, IBM, and Google put parts of their server infrastructure into the public domain. This is especially important in semiconductors since Moore's law has run into a wall, at least economically, even though we have a couple more process generations coming at us.

RISC-V is a new general-purpose instruction-set archi-tecture (ISA) that’s BSD licensed, extensible, and royalty free. It’s clean and modular with a 32-, 64-, or 128-bit inte-ger base and various optional extensions (e.g., floating point). RISC-V is easier to implement than some alterna-tives—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.
