Beagleboard peeps tease dual-core 64-bit RISC-V computer with GPU, AI acceleration, more for $119

UnArmed to the teeth: Early versions to ship in April, more to follow in September


If you’re looking for a modest RISC-V computer capable of running Linux, with AI and other acceleration thrown in, to evaluate the architecture, the people behind the BeagleBoard have teased such a thing: the BeagleV board, starting from $119 (£87).

The single-board computer is the creation of three organizations: chip designer StarFive, Internet-of-Things hardware biz Seeed, and BeagleBoard.org – which is best known for producing affordable Arm-based dev kits, and is now giving RISC-V a shot. StarFive, meanwhile, is linked to SiFive, the RISC-V chip-and-board outfit.

As you'll see, the computer is aimed at engineers, makers, and technologists who want to evaluate the RISC-V architecture and the kinds of processing units, peripherals, and software stacks in its orbit without spending several hundred dollars on higher-end offerings. A Debian-based Linux distro will be available, at least, for the board.

What's on the BeagleV? Here's what we know so far. At its heart is the StarFive JH7100, aka the VIC-7100: this is a 64-bit RISC-V system-on-chip running at up to 1.5GHz. It uses a pair of SiFive-designed U74 RV64GC cores each with a dual-issue, in-order eight-stage pipeline. All the usual MMU and privilege modes are available to run OSes like Linux, and the cores come with 2MB of L2 cache.

We're told the system-on-chip also includes a Tensilica-VP6 Vision DSP to speed up computer vision tasks; an instance of Nvidia’s open-source NVDLA engine, which is a deep-learning accelerator configured with 2,048 MAC units running at 800MHz or 3.5 TOPS; and a neural-network engine featuring 1,024 MACs at 500MHz or 1 TOPS. It's seemingly enough to get going with some network-edge-level AI.

The BeagleV will ship with 4GB of LPDDR4 RAM, with a price tag of $119, or 8GB for $149. According to the team behind it, the computer also includes H.264/H.265 video decode and encode acceleration in hardware that can go up to 4K at 60 FPS; camera and display serial interfaces; HDMI output running up to 1080p at 30 FPS; JPEG hardware encoding and decoding; USB 3.0 ports; gigabit Ethernet; the all important 3.5mm audio jack; an audio DSP; GPIO pins; a microSD slot for the OS and data storage; Wi-Fi and Bluetooth connectivity; and other bits and pieces. Power comes in via USB-C.

One thing to keep in mind is that there will be two spins of the BeagleV: a pilot revision due to ship in April for enthusiastic early adopters, and an updated revision in September. The early version won't sport a dedicated graphics processor, and 8GB of RAM will be the only memory option. Jason Kridner, president of BeagleBoard.org, told El Reg it will still be able to support “a full graphical user interface” via HDMI.

The autumn-expected board will be available for everyone, and include a GPU from PowerVR designers Imagination plus open-source video drivers, we’re told. Presumably, that addition will improve the graphics output of the BeagleV. This enhanced system will also cost $149 for the 8GB model and $119 for the 4GB version.

Kridner also told us that the VIC-7100 system-on-chip will only be available for early Beagle boards, and the later VIC-7110 SoC with the Imagination GPU "will, however, be available for other applications." Said 7110 chip on the later boards is also expected to sport four RV64GC U74 cores. ®

  • Verizon: Ransomware sees biggest jump in five years
    We're only here for DBIRs

    The cybersecurity landscape continues to expand and evolve rapidly, fueled in large part by the cat-and-mouse game between miscreants trying to get into corporate IT environments and those hired by enterprises and security vendors to keep them out.

    Despite all that, Verizon's annual security breach report is again showing that there are constants in the field, including that ransomware continues to be a fast-growing threat and that the "human element" still plays a central role in most security breaches, whether it's through social engineering, bad decisions, or similar.

    According to the US carrier's 2022 Data Breach Investigations Report (DBIR) released this week [PDF], ransomware accounted for 25 percent of the observed security incidents that occurred between November 1, 2020, and October 31, 2021, and was present in 70 percent of all malware infections. Ransomware outbreaks increased 13 percent year-over-year, a larger increase than the previous five years combined.

    These were the words of communication and collaboration platform Mattermost's founder and CTO, Corey Hulen, speaking to The Register about open source, sovereignty and audio bridges.

    "Some of the history of Mattermost is exactly that problem," says Hulen of the issue of closed source software. "We were using proprietary tools – we were not a collaboration platform before, we were a games company before – [and] we were extremely frustrated because we couldn't get our intellectual property out of those systems..."

  • UK government having hard time complying with its own IR35 tax rules
    This shouldn't come as much of a surprise if you've been reading the headlines at all

    Government departments are guilty of high levels of non-compliance with the UK's off-payroll tax regime, according to a report by MPs.

    Difficulties meeting the IR35 rules, which apply to many IT contractors, in central government reflect poor implementation by Her Majesty's Revenue & Customs (HMRC) and other government bodies, the Public Accounts Committee (PAC) said.

    "Central government is spending hundreds of millions of pounds to cover tax owed for individuals wrongly assessed as self-employed. Government departments and agencies owed, or expected to owe, HMRC £263 million in 2020–21 due to incorrect administration of the rules," the report said.

    Internet interruption-watcher NetBlocks has reported internet outages across Pakistan on Wednesday, perhaps timed to coincide with large public protests over the ousting of Prime Minister Imran Khan.

    The watchdog organisation asserted that outages started after 5:00PM and lasted for about two hours. NetBlocks referred to them as “consistent with an intentional disruption to service.”

  • Suspected phishing email crime boss cuffed in Nigeria
    Interpol, cops swoop with intel from cybersecurity bods

    Interpol and cops in Africa have arrested a Nigerian man suspected of running a multi-continent cybercrime ring that specialized in phishing emails targeting businesses.

    His alleged operation was responsible for so-called business email compromise (BEC), a mix of fraud and social engineering in which staff at targeted companies are hoodwinked into, for example, wiring funds to scammers or sending out sensitive information. This can be done by sending messages that impersonate executives or suppliers, with instructions on where to send payments or data, sometimes by breaking into an employee's work email account to do so.

    The 37-year-old's detention is part of a year-long, counter-BEC initiative code-named Operation Delilah that involved international law enforcement, and started with intelligence from cybersecurity companies Group-IB, Palo Alto Networks Unit 42, and Trend Micro.
