  • First Open-Source RISC-V SoC for Linux Released

    Only months after debuting the Freedom U540, the world's first Linux-compatible processor based on the open-source RISC-V chip architecture, RISC-V chipmaker SiFive has surprised the open-source community again by unveiling a full development board built around the ISA.

    Called the HiFive Unleashed, the new development board is built around SiFive's Freedom U540, which is based on the company's U54-MC Coreplex. The chip is a 64-bit, 4+1 multicore processor that fully supports Linux, as well as other operating systems such as FreeBSD and Unix. The development board itself features a 8GB of DDR4 with ECC, a gigabit ethernet port, 32 MB of quad SPI flash memory, a MicroSD card slot, and an FPGA mezzanine card (FMC) connector for allowing peripherals and other expansion devices to be attached to the board.

  • RISC-V plans to fulfill open-source architecture innovation dreams

    Digital transformation and the proliferation of big data are driving a renaissance in software development, requiring new advancements in hardware and processors. With a range of needs from a variety of users and platforms, standard instruction set architectures are no longer fulfilling all use cases as the demand for flexibility and improved performance increases.

    “The world is dominated by two instruction set architectures. … Both are great, but … they’re owned by their respective companies. RISC-V is a third entrant into this world … it’s completely open source,” said Martin Fink (pictured, right), chief technology officer of Western Digital Corp. Through the RISC-V initiative, Fink and Dave Tang (pictured, left), senior vice president of corporate marketing at Western Digital, are working to provide an instruction set that can be freely shared to encourage innovation.

Linux
Hardware

Contemporary Controls is launching a “BASpi” Raspberry Pi add-on that supports the BACnet building control standard and Sedona Framework, and provides 6x relay outputs and 6x inputs, including analog, temp, contact closure, pulse, and resistance inputs.

Home automation is a new phenomenon compared to more established building automation technology, which largely follows the BACnet (Building Automation Control network) standard. We have seen various Linux-ready IoT products that offer some BACnet support, including Echelon’s IzoT Router. However, Contemporary Controls’ new BASpi Raspberry Pi 3 add-on board is the first product we’ve seen that is specifically designed for the standard.

  • Your first robot: The controller [3/5]

    This is the third blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post you were introduced to the Robot Operating System (ROS), and got your robot moving by ROSifying one of the CamJam worksheets. Today we're going to move beyond the CamJam worksheets, and work toward having our robot remotely controlled by focusing on our wireless controller: getting data out of it and into ROS messages.

  • Tough, Atom-based box PC supports EtherCAT

    Taicenn’s Linux-ready “TBOX-4000” industrial box PC provides an Atom D2550, dual GbE ports with EtherCAT support, mSATA, optional wireless, and shock, vibration, and extended temperature resistance.

    Shenzhen based Taicenn Technology has launched a rugged industrial computer that runs Linux or Windows on an old school Intel Atom D2550 “Cedar Trail” processor with dual 1.86GHz cores, 640MHz Intel graphics, and a separate Intel NM10 controller chipset. The TBOX-4000’s D2550 chip has the advantage of being reasonably power efficient (10W TDP), leading to the computer’s under 20W total consumption. It’s also likely to make this computer more affordable than most, although no pricing was listed.

  • Developing an Open Source Voice Assistant: Interview with Mycroft AI’s Steve Penrod

    Mycroft is an industry first. Where Amazon Echo and Google Home are unsurprisingly closed-lipped about their data gathering, we know that recordings gathered from these devices are stored for later use (whatever that might be). Mycroft Mark II, by comparison, is an open source voice platform.

    This means that users of the Mycroft platform can opt into sharing their usage data and designers can then use that data to learn more about demographics, language, and voice recognition.

    On the other hand, users could choose to keep their data private.

    What we know about Mycroft Mark II's hardware is that it has a Xilinx quad-core processor, specifically a Zynq UltraScale+ EG MPSoC. It has an array of six far-field PDM-based MEMs microphones and has hardware acoustic echo cancellation (AEC) for beamforming and noise reduction. It has stereo sound with dual 2" drivers (10 Watts), a 4" IPS LCD touchscreen, BT 2.1+EDR and BLE 4.2 Bluetooth In, and single-band Wi-Fi (2.4 GHz).

  • Hi-Five Unleashed: The first Linux-capable RISC-V single board computer is here

    For roughly a decade, x86-64 has held hegemony over the desktop and server market. In the mobile space, ARM is the popular platform—for which a glut of cheap ARM processors have led to the rise of mass-produced single-board computers (SBCs) like the Raspberry Pi and competitors. However, proprietary "binary blob" drivers make using these devices somewhat more cumbersome, particularly for developers attempting to learn how devices work or ensuring complete device control.

  • The State of RISC-V Hardware & Software In Early 2018
