  • Open Source Processors: Fact Or Fiction?

    Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails.

    Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keynote speeches, technical sessions, and panels. What’s less obvious is that open ISAs are not a new phenomenon, and neither are free, open processor implementations.

  • Will Open-Source EDA Work?

    Open-source EDA is back on the semiconductor industry’s agenda, spurred by growing interest in open-source hardware. But whether the industry embraces the idea with enough enthusiasm to make it successful is not clear yet.

    One of the key sponsors of this effort is the U.S. Defense Advanced Research Projects Agency (DARPA), which is spearheading a number of programs to lower the cost of chip design, including one for advanced packaging and another for security. The idea behind all of them is to utilize knowledge extracted from millions of existing chip designs to make chip engineering more affordable and predictable.

  • Why Autonomous Vehicle Developers Are Embracing Open Source

    There's a growing trend of autonomous vehicle developers open-sourcing their software tools and hardware, even for applications outside of automotive.

  • Rugged open-source inertial measurement unit sensor offers affordable and rugged solution

    ACEINNA offers the new OpenIMU300RI. The device is a rugged, open-source, sealed-package, 9-DOF IMU for autonomous off-road, construction, agricultural and automotive vehicle applications. This new open-source IMU enables engineers to simply optimise an attitude, navigation or other algorithm for their vehicle/application and run it in on the IMU.

    [...]

    “Different vehicle platforms have different dynamics,” explains James Fennelly, product manager at ACEINNA. “To get the best performance, the attitude, navigation or other algorithm needs to be tailored for each vehicle platform and application. The ACEINNA OpenIMU300RI open-source platform gives designers a flexible and simple-to-integrate IMU solution that can be easily optimized for a wide range of vehicles and applications.”

  • Open Source ESP32 3D Printer Board Supports Marlin 2.0 Firmware
  • The Octopus is a 5K full frame open source camera that lets you swap out sensors

    Now that digital imaging sensors are starting to become more freely available to the masses, all kinds of open source projects have been popping up that use them. Most of them are typically fairly limited to things like the Raspberry Pi or development boards like the Arduino and ESP32.

    But now, there is a new and pretty serious looking open source camera out there. It’s called the Octopus, it has interchangeable sensors that go up to 5K full frame, it’s fully programmable and runs on the open source operating system, Linux.

  • ScopeFun open source all-in-one instrumentation

    ScopeFun has launched a new project via Crowd Supply for their open source all-in-one instrumentation hardware aptly named the ScopeFun. ScopeFun Has been created to provide an affordable platform that offers the following tools : Oscilloscope, Arbitrary waveform generator, Spectrum analyzer, Logic analyzer and Digital pattern generator .

    The hardware supports any accompanying software runs on Windows, Linux, and Mac and also provides a Server Mode that supports remote connections over an IP network. “A Xilinx Artix-7 FPGA and a Cypress EZ-USB FX3 controller allow the board to interface with a PC while maintaining fast data rates. Samples are buffered using 512 Megabytes of DDR3 SDRAM.

  • Bloom Chair is an open source furniture that lets you design your own piece

    Call it modular, call it DIY, call it I-have-control-over-my-interiors; the purpose of the Bloom Chair is to let you customize your chair, just the way you like it to be. It’s a collaborative effort between you and the manufacturer, where you get to download the modular design, cut it yourself and finally assemble it. While you make your piece, you have the liberty of modifying the pattern and making the end-shape define your vision. Haffun!

Intel Announces 12th Gen Core "Alder Lake" CPUs, Linux Tests Forthcoming

Intel is using their inaugural Intel Innovation virtual event today to formally announce the highly-anticipated 12th Gen Core "Alder Lake" processors. These first desktop processors built on their "Intel 7" process and employ a hybrid architecture will be available in retail channels next week. Today we can talk more about Alder Lake specifications and features while our Linux performance benchmarks and support analysis will come once the Alder Lake review embargo expires next week. While there have been many Alder Lake leaks in recent weeks/months and a number of features disclosed back during Architecture Day, today marks the official unveil for the next-gen Intel Core processors. This is a very exciting transition as they have now shifted to their Intel 7 manufacturing process, the hybrid architecture provides a combination of high performance and low power cores depending upon needs, and Intel is at the forefront now in delivering DDR5 memory and PCIe 5.0 to the masses. When it comes to performance, Intel claims Alder Lake can deliver up to two times the performance of prior generation processors for content creation workloads. Meanwhile when it comes to the generational performance uplift for the P (Performance) cores it's said to be around 19%. Read more

Murena smartphones and cloud will protect our privacy

More than ever the market is demanding a new approach for digital products: more and more people around the world want something different, more ethical, more sustainable, with real guarantees about personal data protection. Four years ago, I wanted to break free from Google and Apple, and therefore we created the “eelo” project, with the simple idea that a different mobile operating system and associated cloud services like email or cloud storage could be possible in this world. Followed by an amazing community of supporters, contributors and now users, the project progressed quickly, and became a reality by the end of 2018. The same year, we had to suddenly abandon our initial project name for a temporary name: /e/. Sometimes, temporary things last longer than expected. And despite being hard to pronounce, difficult to search, and largely criticized by many people, /e/ as a brand name had the benefit to be very singular and helped us appear different. In the end it conveyed the idea that we’re doing something special. […] Nevertheless, as we are reaching more and more people and progressively catching interested from a mainstream audience, we have to introduce a new, strong brand, easier to use, easier to refer to and easier to share with people. The goal of this brand is to have a strong name to call our products, intended to be used by a large number of users in many different countries and cultures. It took some time, since we had many different candidates, both from internal suggestions and from our community. We wanted something that would both convey our project’s values, and that could be within the same lineage of our initial project name. We also had to secure this new brand making sure it was not already in use in the same field of activity, and by entering a long trademark registration processes. Read more
