It is no secret that silicon manufacturing is an expensive and difficult process which requires big investment and a lot of effort to get right. Take Intel's 10 nm for example. It was originally planned to launch in 2015, but because of technical difficulties, it got delayed for 2019. That shows how silicon scaling is getting more difficult than ever, while costs are rising exponentially. Development of newer nodes is expected to cost billions of Dollars more, just for the research alone and that is not even including the costs for the setting up a manufacturing facility. In order to prepare for the moment when the development of ever-decreasing size nodes becomes financially and physically unfeasible, researchers are exploring new technologies that could replace and possibly possess even better electrical properties than silicon. One such material (actually a structure made from it) is Carbon Nanotube or CNT in short.

Researchers from MIT, in collaboration with scientists from Analog Devices, have successfully built a CPU based on RISC-V architecture entirely using CNTs. Called RV16X Nano, this CPU is currently only capable of executing a classic "Hello World" program. CNT is a natural semiconductor, however, when manufactured, it is being made as a metallic nanotube. That is due to the fact that metallic nanotubes are easier to integrate into the manufacturing ecosystem. Its has numerous challenges in production because CNTs tend to position themselves randomly in XYZ axes. Researchers from MIT and Analog Devices solved this problem by making large enough surfaces so that enough random tubes are positioned well.

Western Digital Corp. today announced that Martin Fink, executive vice president and chief technology officer, will be transitioning to retirement and moving to an advisory role with the Company. Mr. Fink will continue to report to Steve Milligan, chief executive officer, and advise Mr. Milligan and the executive team on matters relating to data center architectures, including RISC-V. Dr. Siva Sivaram, executive vice president, Silicon Technology and Manufacturing, has been appointed to the newly created role of President, Technology and Strategy, effective immediately. In this expanded strategic role, Dr. Sivaram will oversee Western Digital's key technology initiatives and corporate strategy.

Dr. Sivaram has more than 35 years of experience in semiconductor technology and manufacturing. Prior to joining Western Digital in 2016 following the acquisition of SanDisk, he held executive positions at Intel and Matrix Semiconductor. Additionally, he was the founder and CEO of Twin Creeks Technologies, a solar panel and equipment company.

"Siva has been instrumental in leading the ongoing development of our 3D flash memory and other next generation technologies," said Steve Milligan, Western Digital chief executive officer. "Looking to the future, I am confident that with Siva's expertise, we will be well positioned to further strengthen Western Digital's leading technology position and innovative product portfolio."

The European Processor Initiative(EPI), crucial element of the European exascale strategy, delivers its first architectural design to the European Commission and welcomes new partners Almost six months in, the project that kicked off last December has already delivered its first architectural designs to the European Commission, thus marking initial milestones successfully executed. The project that will be the cornerstone of the EU's strategic plans in HPC initially brought together 23 partners from 10 European countries, but has now welcomed three more strong additions to its EPI family. EPI consortium aims to bring a low-power microprocessor to the market and ensure that the key competences for high-end chip design remain in Europe. The European Union's Horizon 2020 program funds this project with a special Framework Partnership Agreement. The initial stage is a three-year Specific Grant Agreement, which lasts until November 2021.

As the trade war between the US and China continues to unfold, we are seeing major US companies ban or stop providing service to China's technology giant Huawei. Now, it looks like the trade war has crossed the ocean and reached the UK. This time, UK based ARM Holdings, the provider of mobile chip IP for nearly all smartphones and tablets, has revoked the license it has given Huawei.

According to the BBC, ARM Holdings employees were instructed to suspend all interactions with Huawei, and to send a note informing Huawei that "due to an unfortunate situation, they were not allowed to provide support, deliver technology (whether software, code, or other updates), engage in technical discussions, or otherwise discuss technical matters with Huawei, HiSilicon or any of the other named entities." The news came from an internal ARM document the BBC has obtained.

Western Digital Corp. today announced at the RISC-V Summit three new open-source innovations designed to support Western Digital's internal RISC-V development efforts and those of the growing RISC-V ecosystem. In his keynote address, Western Digital's Chief Technology Officer Martin Fink unveiled plans to release a new open source RISC-V core, an open standard initiative for cache coherent memory over a network and an open source RISC-V instruction set simulator.

These innovations are expected to accelerate development of new open, purpose-built compute architectures for Big Data and Fast Data environments. Western Digital has taken an active role in helping to advance the RISC-V ecosystem, including multiple related strategic investments and partnerships, and demonstrated progress toward its stated goal of transitioning one billion of the company's processor cores to the RISC-V architecture.

You may never have heard of SiFive before -and that's perfectly understandable. The startup has just been brought from the ground-up following a round of funding, which netted it some $50.6 million dollars in the old, pre-ICO-preferred ways for funding: venture capital. The objective: to offer other startup companies a way to bring their idealized silicon into actual, custom silicon based on the RISC-V architecture, and then work with them towards achieving actual large-scale production.

The company will have available for customers options of IP and pre-baked designs which they can mix and match according to their needs, alongside small-scale production capability for companies to have their actual product - and test it in real-world conditions - before entering large-scale production. This move by SiFive aims to enable a larger variety of task-specific processor designs, ushering in a new, more liberal area of chip design and production.

Recent articles in the media have raised awareness around the processor security vulnerabilities named Meltdown and Spectre. These vulnerabilities are particularly troubling as they are not due to a bug in a particular processor implementation, but are a consequence of the widespread technique of speculative execution. Many generations of processors with different ISAs and from several different manufacturers are susceptible to the attacks, which exploit the fact that instructions speculatively executed on incorrectly predicted code paths can leave observable changes in micro-architectural state even though the instructions' architectural state changes will be undone once the branch prediction is found incorrect. No announced RISC-V silicon is susceptible, and the popular open-source RISC-V Rocket processor is unaffected as it does not perform memory accesses speculatively.

Western Digital Corp. announced today at the 7th RISC-V Workshop that the company intends to lead the industry transition toward open, purpose-built compute architectures to meet the increasingly diverse application needs of a data-centric world. In his keynote address, Western Digital's Chief Technology Officer Martin Fink expressed the company's commitment to help lead the advancement of data-centric compute environments through the work of the RISC-V Foundation. RISC-V is an open and scalable compute architecture that will enable the diversity of Big Data and Fast Data applications and workloads proliferating in core cloud data centers and in remote and mobile systems at the edge. Western Digital's leadership role in the RISC-V initiative is significant in that it aims to accelerate the advancement of the technology and the surrounding ecosystem by transitioning its own consumption of processors - over one billion cores per year - to RISC-V.
