    Layoffs at SiFive as RISC-V upstart turns focus to custom cores

    Layoffs at SiFive as RISC-V upstart faces a crossroads
    https://www.edn.com/layoffs-at-sifive-as-risc-v-upstart-faces-a-crossroads/?fbclid=IwAR1DEqJFfyMaXDEYZ3FCDCX1eLaUhdNLYWan2Ew6ivMTWp_pDu2UVKjHSok

    SiFive, a prominent player in the RISC-V design arena, is going through a radical makeup. While layoffs at one of the early RISC-V startups are making headlines in trade media, what’s happening underneath is a significant shift in its business model.

    The well-funded RISC-V upstart built its business around two product lines. First, pre-designed and silicon-proven RISC-V cores that designers can pick to develop their system-on-chips (SoCs). SiFive has been shipping these ready-made RISC-V cores along with a debugging tool that can be used to test the reliability of an SoC design before manufacturing.

    Second, custom cores that SiFive designed with specific requirements; these custom cores are later installed into an SoC. The news behind this layoff story is that SiFive is dumping its low-cost RISC-V core business to focus on custom cores.

    Still, layoffs have been massive. Though media reports vary on numbers ranging from 100 to more than 300, design engineers have borne the brunt of this restructuring.

    Linux on Scratch Is Proven Possible, Thanks to This Clever RISC-V Emulator Project
    https://www.hackster.io/news/linux-on-scratch-is-proven-possible-thanks-to-this-clever-risc-v-emulator-project-815bf0937ec7

    Running a Scratch port of Charles Lohr’s RISC-V emulator, this clever project achieves the seemingly impossible.

    Pseudonymous developer “bilman66″ has achieved the seemingly impossible by getting a Linux operating system to boot in the Scratch visual coding environment — by writing a Scratch RISC-V emulator.

    “A real build of the Linux 6.1.14 kernel running in pure Scratch code,” bilman66 writes of their creation, brought to our attention by Adafruit. “The Linux build comes with the usual programs like cat/echo and is fully capable of running shell scripts, but it also comes with Duktape (a JavaScript engine), as well as ed for text editing, and CoreMark for benchmarking.”

    CH32 RISC-V MCUS GET OFFICIAL ARDUINO SUPPORT
    https://hackaday.com/2024/01/04/ch32-risc-v-mcus-get-official-arduino-support/

    Like many of you, we’ve been keeping a close eye on the CH32 family of RISC-V microcontrollers from WCH Electronics. You can get the CH32V003, featuring 2 kB RAM and 16 kB of flash for under fifteen cents, and the higher-end models include impressive features like onboard Ethernet. But while the hardware is definitely interesting, the software side of things has been a little rocky compared to what we’ve come to expect from modern MCUs.

    Things should start looking up a bit though with the release of an Arduino core for the CH32 direct from WCH themselves. It’s been tested on Windows, Linux, and Mac, and supports the CH32V00x, CH32V10x, CH32V20x, CH32V30x, and CH32X035 chips.

    Hangover Aiming For RISC-V Support This Year, x86_64 Emulation

    Building off this week’s release of Wine 9.0 for running Windows games and applications on Linux and other platforms is now Hangover 9.0. Hangover as a reminder is the project based on Wine initially focused on running x86 32-bit Windows apps on AArch64 Linux. Hangover works by running Wine atop various emulators such as QEMU, FEX, or Box64 for handling the processor/ISA translation.

    Hangover 9.0 is now available and has Wine 9.0 plus the latest goodies on the Hangover side. Hangover in recent months has seen QEMU support for WOW64 emulation, improved FEX support, Box64 support was fully integrated, Debian packages, and continuing to prove the performance and capabilities of Hangover
