  • X-FAB Silicon Foundries tapes-out open-source RISC-V MCU

    Together with crowd-sourcing IC platform partner Efabless Corporation, X-FAB Silicon Foundries has announced the first-silicon availability of the Efabless RISC-V System on Chip (SoC) reference design.

    This open-source semiconductor project went from design start to tape-out in less than three months using the Efabless design flow based on open-source tools. The mixed-signal SoC, called Raven, is based on the community developed ultra-low power PicoRV32 RISC-V core. Efabless has bench-tested the Raven at 100MHz, and based on simulations the design should be able to operate at up to 150MHz.

    The open-source top-level design uses X-FAB proprietary analog IP and is created with an open-source design flow. This hybrid open-source design brings the power of open innovation and at the same time protecting significant investment in proprietary IP.

  • X-FAB and Efabless Announce Successful First Silicon of Raven, An Open-Source RISC-V Microcontroller

    X-FAB Silicon Foundries, the leading analog/mixed-signal and specialty foundry, together with crowd-sourcing IC platform partner Efabless Corporation, today announced the successful first-silicon availability of the Efabless RISC-V System on Chip (SoC) reference design. This open-source semiconductor project went from design start to tape-out in less than three months using the Efabless design flow based on open-source tools. The mixed-signal SoC, called Raven, is based on the community developed ultra-low power PicoRV32 RISC-V core. Efabless has successfully bench-tested the Raven at 100MHz, and based on simulations the design should be able to operate at up to 150MHz.

  • X-FAB and Efabless Deliver Open Source Mixed-Signal SoC

    Mixed signal foundry X-FAB Silicon Foundries and crowd-sourcing IC platform Efabless Corp. have announced silicon availability of a RISC-V based mixed signal system-on-chip (SoC) reference design. The open-source semiconductor project went from design start to tape-out in less than three months using the Efabless design flow based on open-source tools.

Audiocasts/Shows: This Week in Linux, Command Line Heroes, DevNation Live Introducing Kogito and Python Podcast

  • Episode 75 | This Week in Linux

    On this episode of This Week in Linux, we’ve got a lot of Distro News with the first stable release of EndeavourOS, and we’ve also got new releases from Proxmox, deepin and FerenOS. Dropbox has decided to revert their weird decision of blocking various Linux Filesystems so we’ll talk about that. We’ve got some App News with KDE Connect now being available for macOS and a new release for the Foliate, ebook reader. Later in the show, we’ll cover some Linux Security news regarding a recently found piece of malware targeting the Linux Desktop. Then we’ll round out the show with some Linux Gaming news from Epic Games, Valve, Google Stadia and a new Humble Bundle. All that and much more on Your Weekly Source for Linux GNews!

  • JavaScript's surprising rise from the ashes of the browser wars on Command Line Heroes

    The third season of the Command Line Heroes podcast continues its look at the history of the programming languages we depend on every day. Episode 3, released today, investigates the origin of JavaScript. Here's the unlikely story of how it happened.

  • DevNation Live: Introducing Kogito

    DevNation Live tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about Quarkus, Kogito, and GraalVM from Red Hat’s Mario Fusco, Principal Software Engineer, and Burr Sutter, Chief Developer Evangelist. These days rule engines are often overlooked, possibly because people think that they are only useful inside heavyweight enterprise software products. However, this is not necessarily true. Simply put, a rule engine is just a piece of software that allows you to separate domain and business-specific constraints from the main application flow. Drools is the rule engine of Red Hat, and our goal is to make it ready to be used in serverless environments.

  • Protecting The Future Of Python By Hunting Black Swans

    The Python language has seen exponential growth in popularity and usage over the past decade. This has been driven by industry trends such as the rise of data science and the continued growth of complex web applications. It is easy to think that there is no threat to the continued health of Python, its ecosystem, and its community, but there are always outside factors that may pose a threat in the long term. In this episode Russell Keith-Magee reprises his keynote from PyCon US in 2019 and shares his thoughts on potential black swan events and what we can do as engineers and as a community to guard against them.
