J-core is a clean-room open source processor and SOC design using the SuperH instruction set, implemented in VHDL and available royalty and patent free under a BSD license.
The rest of this page explains how to compile and install a "bitstream" file to implement this processor in a cheap (about $50) FPGA board, then how to build Linux for that board and boot it to a shell prompt.

2018-10-04: technologists and U.S. trade hawks have a common but perhaps impossible mission: reverse decades of globalization in computing to try to prevent damaging attacks. Computer Networks Are Now Permanently Hackable. The web of parts makers, assemblers, testers and contractors is almost impossible to untangle.
The supply chain attack could have siphoned corporate secrets and government information while leaving few fingerprints. It’s the most insidious kind of digital spying imaginable, and some of the savviest tech minds in the world haven’t yet found a reliable way to sniff out the hardware-infiltration attacks, according to the Bloomberg Businessweek reporting. And worse, I’m not sure what, if anything, could be done to prevent this kind of snooping.
Perhaps the only surefire prevention is for Google, Apple, the U.S. government and others to build every circuit and computer chip by hand and make sure the parts and equipment never leave the sight of people they trust. This seems impossible. It would cost a fortune, of course, and it may not be practically possible at all. Over the decades, companies in China, Taiwan, the U.S., Vietnam and elsewhere in the world have developed specialization at discrete steps in manufacturing or assembly for computing equipment. It would takes years and support from the U.S. government to replicate that specialization entirely in the U.S. or other countries that American companies and the government trust.
2018/10/01: China's biggest tech firm announced Wednesday that the new business will develop artificial intelligence chips for cloud computing, internet-connected devices and other sectors.
Alibaba's chief technology officer, Jeff Zhang, said the e-commerce company's advantages in algorithms and data put it in "a unique position to lead real technology breakthroughs in disruptive areas, such as quantum and chip technology."
Alibaba (BABA) has previously made several investments in chipmakers. Earlier this year, it bought C-Sky, a Chinese chip design firm.
Alibaba Executive Chairman Jack Ma has been vocal about addressing China's heavy reliance on foreign-made chips.
"The market for chips is controlled by America ... and suddenly if they stop selling, what that means, you understand," Ma told university students in Tokyo in April. "That's why China, Japan and any country — you need core technologies."
Ma's remarks came shortly after the US Commerce Department blocked American companies from selling parts to ZTE (ZTCOF), a Chinese tech company that relied on US suppliers, including chipmakers, to manufacture smartphones and telecommunications equipment.

The Mill is a new general-purpose high-performance processor design from out-of-the-box computing (http://ootbcomp.com/)
. They claim to beat typical high-end out-of-order (OOO) designs like the Intel Haswell generation by crazy factors, such as being 2.3x faster while using 2.3x less power compared to a Haswell. All the while costing less. Ignoring the cost aspect, the power and performance numbers are truly impressive - especially for general code. How can they do something so much better than what we have today? For general code? That requires some serious innovation. With that perspective, I ask myself where the Mill is really significantly different from what we have seen before.
It is a pity that smartphones and tablets did not come along earlier and did not need 64-bit processing and memory addressing sooner than they did. Had

3D printing technology can produce complex objects directly from computer aided digital designs. The technology has traditionally been used by large companies to produce fit and form concept prototypes ('rapid prototyping') before production. In recent years however there has been a move to adopt the technology as full-scale manufacturing solution. The advent of low-cost, desktop 3D printers such as the RepRap and Fab@Home has meant a wider user base are now able to have access to desktop manufacturing platforms enabling them to produce highly customised products for personal use and sale. This uptake in usage has been coupled with a demand for printing technology and materials able to print functional elements such as electronic sensors. Here we present formulation of a simple conductive thermoplastic composite we term 'carbomorph' and demonstrate how it can be used in an unmodified low-cost 3D printer to print electronic sensors able to sense mechanical flexing and capacitance changes. We show how this capability can be used to produce custom sensing devices and user interface devices along with printed objects with embedded sensing capability. This advance in low-cost 3D printing with offer a new paradigm in the 3D printing field with printed sensors and electronics embedded inside 3D printed objects in a single build process without requiring complex or expensive materials incorporating additives such as carbon nanotubes.
Embedding sensors and electronics inside of 3D objects in a single build process has been a long sought after ...
