Alibaba T-Head TH1520 RISC-V processor to power the ROMA laptop

The ROMA RISC-V laptop was announced this summer with an unnamed RISC-V processor with GPU and NPU. We now know it will be the Alibaba T-Head TH1520 quad-core Xuantie C910 processor clocked at up to 2.5GHz with a 4 TOPS NPU, and support for 64-bit DDR at up 4266 MT. The TH1520 is born out of the Wujian 600 platform unveiled by Alibaba in August 2022, and is capable of running desktop-level applications such as Firefox browser and LibreOffice office suite on OpenAnolis open-source Linux-based operating system launched by Alibaba in 2020. So that means we now have a better idea of the specifications of the ROMA RISC-V developer laptop: SoC – Alibaba T-Head quad-core RISC-V Xuantie C910 processor @ 2.5 GHz, unnamed Imagination GPU for graphics, 4 TOPS NPU for AI System Memory – Up to 16GB LPDDR4/LPDDR4X RAM Storage – Up to 256GB eMMC flash Display – 14.1-inch […]

Linux 6.0 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.0 has just been released by Linus Torvalds: So, as is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes. But of course there’s a lot of various changes in 6.0 – we’ve got over 15k non-merge commits in there in total, after all, and as such 6.0 is one of the bigger releases at least in numbers of commits in a while. The shortlog of changes below is only the last week since 6.0-rc7. A little bit of everything, although the diffstat is dominated by drm (mostly amd new chip support) and networking drivers. And this obviously means that tomorrow I’ll open the merge window for 6.1. Which – unlike 6.0 – has a number of fairly core new things lined up. But for now, please do give this most […]

OpenHarmony development board borrows BBC Micro:bit edge connector

OpenHarmony development board BBC micro bit

HopeRun’s HiHope development board features a HiSilicon Hi3861V100 32-bit RISC-V microcontroller compatible with OpenHarmony OS and looks very much like the BBC Micro:bit educational board notably with its edge connector. The board is also designed for youth education (in China) and comes with similar sensors, but there are some differences such as a 0.96-inch OLED instead of an LED matrix and support for offline voice recognition. There’s no wireless connectivity apart from NFC support.

SiFive unveils Automotive E6-A, X280-A, and S7-A RISC-V processors

RISC-V is coming to your car too, with the introduction of SiFive Automotive E6-A, X280-A, and S7-A RISC-V processors designed for automotive applications such as infotainment, cockpit, connectivity, ADAS, and electrification. Those are built on the existing SiFive Essential 6-series E6 32-bit real-time cores, SiFive Intelligence X280 64-bit RISC-V processor with AI extensions, and SiFive S7 64-bit real-time cores (equivalent to Cortex-R7/R8), but adds safety, security, and performance required by the automotive market such as ASIL compliance. Each new core targets specific applications within a vehicle: The SiFive E6-A series will be found in system control boards, hardware security modules (HSMs) and safety islands, as well as standalone in microcontrollers. The SiFive S7-A 64-bit real-time core is said to be suited to the needs of SoCs with performant safety islands, requiring both low latency interrupt support and the same 64-bit memory space as the main application CPUs. The SiFive X280-A […]
