Date: 2026-08-28　Source: People’s Daily Online Jiangsu Channel, Xinhua Daily, 2500sz News

On August 28, the 2026 Open Source Innovation Ecosystem Conference, themed “Open Source Convergence · Intelligent Symbiosis,” was held in Suzhou, officially releasing the OpenAtom Zijin Zone OPC Incubation Action Plan: with JSopen as the core digital foundation and relying on the dual-center linkage of “Suzhou Wuzhong + Nanjing Yuhua,” it aims to build China’s first AI OPC professional open source incubation community. The event featured the unveiling of the OPC Project Incubation Center and the signing of 16 first-batch resident projects (covering AI large models, embodied intelligence, and medical technology); the Zijin Open Source OPC Innovation Investors Alliance was launched, and the Jiangsu Yuntu Kaiyuan Venture Capital Fund was unveiled (an OPC industry fund matrix with a planned total scale of no less than RMB 1 billion, alongside a RMB 30 million AI micro-seed fund established jointly with Nanjing Yuhuatai District). Directly related to RISC-V: the RISC-V Open Source Chip Industry Innovation Center was officially launched as one of the five provincial-level open source ecosystem innovation platforms in the Suzhou pilot, with the OpenHarmony Application Innovation Center and the Zijin Open Source AI Empowerment Center also landing simultaneously; Ecovacs Eight Realms Open Source Smart Innovation Space, the BoCloud BoHub community, and open source innovation laboratories at three universities were unveiled, and the 8th Global Campus AI Algorithm Elite Competition (AI + Open Source) was launched concurrently. This event landed on 08-28 and was reposted by multiple media outlets on the morning of 08-30, representing an important signal for Jiangsu’s open source industry policy and RISC-V ecosystem platform development.

Date: 2026-08-29　Source: Desde Linux, lowRISC OpenTitan News, Google Open Source Blog

Spanish-language tech media outlet Desde Linux published a feature article on Google OpenTitan on 08-29, introducing the world’s most active open source silicon project (an open source secure root of trust RoT chip based on the RISC-V Ibex core). The article is educational in nature, but the background information is worth recording: OpenTitan was mass-produced by Nuvoton in 2025-02 and first deployed in production in Chromebooks, making it the first open source RoT to support post-quantum cryptography (SLH-DSA PQC secure boot); during 2026, Real Intent and Cadence joined successively as tool partners, strengthening the open source silicon signoff and verification chain, with total community commits exceeding 33,000. There were no new OpenTitan releases or events within the window; this is included as a reference for the continued penetration of the open source silicon ecosystem.

II. Product and Ecosystem Developments

2.1 StarFive Dubhe-100 Officially Delivered: China’s First Server-Class RISC-V CPU IP to Reach Deliverable Status

Date: 2026-08-27 (supplementary inclusion)　Source: Sina Tech/Kuaikeji, Tencent News, StarFive Technology Official Website

Kuaikeji news on August 27: StarFive Technology announced that its server-class RISC-V HPC CPU core design Dubhe-100 has been officially delivered — this is China’s first server-class RISC-V CPU IP to reach deliverable status, having been adopted by customers and entered the server chip development stage, filling the gap in domestic RISC-V high-performance computing IP. Core specifications: performance benchmarked against Arm Cortex-A78, with integer IPC reaching SPECint2006 15/GHz; deep out-of-order execution, 15-stage pipeline, 6-issue width, 256-instruction out-of-order window; strictly compliant with the RVA23 specification, and the first to implement an industry-leading out-of-order vector unit (RVV); supports single-core/dual-core/quad-core clusters and TileLink, AXI, ACE, and CHI interconnects, and can connect to the in-house NoC IP StarNoC-700 to scale up to 256 cores; has completed full Type 1/Type 2 Hypervisor support, with Linux and KVM virtualization solutions running stably; simultaneously launched server-class infrastructure IP including the AIA advanced interrupt architecture and IOMMU. On the commercial front, LECARC has confirmed it will use Dubhe-100 to develop a next-generation server CPU for intelligent edge applications (the two parties announced their cooperation on 06-29). Note: the debut of Dubhe-100 (08-19) was already covered in this briefing; “official delivery” is its subsequent milestone, which was missed because the gnews StarFive query in the previous two days was polluted by mislabeled 301536.SZ SigmaStar semi-annual report results, and is included today as a supplementary item.

III. Domestic Team Updates and Deep Dives

3.1 Nuclei Listed on NEEQ Innovation Tier (875127): China’s Leading RISC-V CPU IP Vendor Enters Capital Markets

Date: 2026-08-28　Source: Tongbi Finance/Sina Finance, 10jqka, EqualOcean Data/NetEase

Nuclei Zhirong Semiconductor Technology (Shanghai) Co., Ltd. (securities abbreviation: Nuclei, code 875127) had its listing application approved and was officially listed on the NEEQ Innovation Tier on August 28, with China Merchants Securities as lead broker. Founded in 2018 by Hu Zhenbo (author of Hummingbird E203, China’s first open-source RISC-V processor core), the company is among China’s first commercial RISC-V CPU IP suppliers: its products span the N series for low-power embedded, UX series for high energy efficiency, NA series for automotive-grade (the world’s first ISO 26262 ASIL-D certified RISC-V CPU IP), and NI series for AI compute (among the earliest globally to support VLEN 1024 bits); it has licensed to over 300 customers (including listed companies such as GigaDevice, Bestechnic, Amlogic, and Motorcomm), ranking among the global top four RISC-V CPU IP vendors by shipment volume according to the SHD Group 2026-03 report. Financials and funding: 2024/2025 revenue was RMB 73.9987 million/82.9411 million, with losses narrowing period by period after excluding share-based payment effects (-17.2273 million/-9.5863 million/-3.7756 million), and operating cash flow turning positive in 2025 (RMB 7.9203 million); concurrent with the listing, it made a targeted issuance of approximately 82,100 shares, raising about RMB 42 million (subscribers being Heilongjiang Zhenxing Advanced Manufacturing Industry Fund and SMIC Xicheng Beijing Digital Technology Fund), with proceeds directed toward R&D of a RISC-V chip customization platform. Its shareholder roster includes Xiaomi Yangtze River Industry Fund, Legend Capital, CETC Fund, and VeriSilicon (top ten shareholders hold a combined 73.01%). Background: in 2025-08 VeriSilicon had planned to acquire 97% of Nuclei’s equity, announcing termination that December (the target’s demands diverged from market conditions and policy requirements), after which Nuclei pivoted to an independent listing; this listing provides a funding channel for the company’s four-stage strategic upgrade from IP licensing to chip customization, Chiplet, and server CPUs. On the same day, EqualOcean Data categorized it under the “manufacturing sector investment and financing daily” listing category (estimated total financing of about RMB 300 million, including undisclosed figures).

3.2 Sophgo Hardens sophon-tools Security Ahead of Release; SophLiteOS v2.2.6 and Other Fixes Merged

Date: 2026-08-29　Source: sophgo/sophon-tools commit log

Sophgo made 5 commits within the window (sophgo/sophon-tools, all merged on the evening of 08-29), themed around pre-release security checks and hardening: first, same-origin validation and rate-limiting hardening for the /agent/ws service, plus fallback lookup for the CV84X2 device tree (dts) (#160); second, a P1/P2-level security hardening batch — the registration flow rejects temporary tokens, firewall-protected port guards are tightened, and details such as package names/quotes/exit codes/jwt/timeouts/metrics tokens are fixed (#161); third, a fix for the SophLiteOS agent double-reply issue — history is normalized and deduplicated by kind, released with v2.2.6 (#157); fourth, OTA pre-checks intercept incomplete flashing packages to prevent OTA infinite loops (#158); fifth, psocbak backups exclude external data disk mount points and synchronize ota_update md5 (#159). sophon-tools is Sophgo’s SophOS/flashing and OTA toolchain; this batch of commits represents a systematic security and stability convergence on the eve of release, an engineering reinforcement of the mass-production support tooling for the CV84X series (whose official specifications were reported yesterday).

3.3 XiangShan: Ftq Prefetch Performance Tuning, KunminghuV2 CI Options, and Deterload Tool H/V Extension Support

Date: 2026-08-29　Source: OpenXiangShan/XiangShan, OpenXiangShan/Deterload

The OpenXiangShan organization made 4 commits within the window: two in the main XiangShan repository — perf(Ftq) sets the branch prefetch run-ahead distance (BpRunAheadDistance) to the icache way lookup depth (#6425, 08-29 17:23 Beijing time), and ci(perf) adds a new performance regression trigger option for the KunminghuV2 configuration (#6437); two in the XiangShan Lab Deterload tool — adding a hello example with H/V extensions and adding enableV/enableH parameters to builders (around 08-29 21:40), enabling the deterministic workload generation toolchain to cover virtualization and vector extension verification scenarios. Overall this is routine performance tuning and toolchain capability expansion, modest in scale but clear in direction: the CI performance regression system for the KunminghuV2 configuration and Deterload’s H/V support both serve the verification and tuning loop for XiangShan’s next-generation core.

3.4 SpacemiT P3 PMIC Datasheet Documentation Lands; Revyos Updates SG2044 Firmware (Brief)

Date: 2026-08-29/08-30　Source: spacemit-com/docs-chip, revyos/firmware-sg204x

The SpacemiT docs-chip repository added P3 power management IC (PMIC) datasheet documentation (bilingual Chinese-English, 08-29 19:44 Beijing time), continuing its engineering accumulation of hardware documentation (the AVL documentation work was reported the previous day). The Revyos organization’s firmware-sg204x repository made two commits: updating the fsbl.bin boot firmware for the SG2044 platform, and switching the EDK2 build to the Linux cross-compiler (early morning 08-30), a routine iteration of the UEFI firmware chain for the SG2044 platform. Both teams saw only small-step iterations within the window, with no architectural-level changes.

IV. Embodied Intelligence and Robotics Special Section

4.1 Kaihong Releases M-Robots OS 3.0 Beta: OpenHarmony Robot OS Shifts Focus to Swarm Intelligence

Date: 2026-08-29　Source: Sina Tech/ITHome, Kaihong Official Site

At the 2026 China International Big Data Industry Expo in Guiyang, Kaihong Senior Vice President Wang Hao officially released M-Robots OS 3.0 Beta. M-Robots OS is China’s first distributed heterogeneous multi-robot collaborative robot operating system based on OpenHarmony. Version 3.0 Beta shifts its focus from “single-machine capability” to “swarm intelligence,” with systematic upgrades across four directions: security, real-time performance, swarm intelligence, and digital foundation. On the security side, it builds a three-dimensional defense of “trusted networking, controllable access, and defensible operation.” Kaihong had just launched M-Robots community co-building on 06-26 (the first OpenHarmony robot operating system community) and continues to participate in OpenHarmony/RISC-V ecosystem competitions and hardware adaptation. There were no new RISC-V embodied intelligence hardware products in this window; this item is included as an OpenHarmony robotics ecosystem development—alongside yesterday’s Microduck (a Hugging Face ecosystem bipedal robot), it corroborates the pattern that “terminal main controllers still rely primarily on ARM/existing ecosystems, while RISC-V leads in standards and governance layers in embodied intelligence.” However, the hardware adaptation surface of the OpenHarmony robot OS already covers RISC-V development boards, making it a potential penetration channel worth tracking.

4.2 Global Embodied Intelligence Robot Industry Expo Concludes, 3.9 Billion Yuan in Deal Intentions Reached in 3 Days

Date: 2026-08-30　Source: Sohu reposting Shenzhen Special Zone Daily, Guancha

The 2026 AGIC Shenzhen International General Artificial Intelligence Industry Expo and GERX Global Embodied Intelligence Robot Industry Expo, held in Shenzhen from August 26-28, has concluded. Shenzhen Special Zone Daily reported 3.9 billion yuan in deal intentions over 3 days, with 1,200 mature exhibits available for direct ordering and over 7,000 overseas buyers in attendance. Meanwhile, following the World Robot Conference (Beijing), a “robot sports meet” sparked discussion on the “acceleration and brakes” of embodied intelligence (Guancha, 08-29), with industry focus shifting from technology demonstrations to deployment and reliability. Such industry-level progress serves as an external environment indicator for the RISC-V embodied intelligence ecosystem: China’s embodied intelligence industry is entering a phase of commercial scaling, continuously opening demand windows for edge-side chips (including RISC-V).

4.3 Still No New RISC-V Embodied Intelligence Hardware in This Window (Pattern Continues)

Date: 2026-08-29~08-30　Source: Consolidated gnews/HN/GitHub search

In this window, gnews robot-related queries (embodied intelligence, risc-v robot, etc.) returned only industry trends and OpenHarmony ecosystem news, with no new RISC-V embodied intelligence hardware releases; GitHub commits from various RISC-V teams also showed no new embodied-related repositories. Consistent with yesterday’s conclusion: RISC-V in embodied intelligence remains at the stage of “standards and governance layers leading (MIPS promoted to RISC-V International premier member), terminal deployment yet to be observed,” with middleware ecosystems such as the OpenHarmony robot OS (M-Robots OS) serving as potential penetration channels.

V. Summary and Trend Observations

  1. Capital market milestone: Nuclei (875127) listed on the NEEQ Innovation Tier on August 28, becoming China’s first commercial RISC-V CPU IP company to enter the capital markets (independently listed after VeriSilicon’s terminated acquisition at the end of 2025), with a targeted issuance raising approximately 42 million yuan for RISC-V chip customization platform R&D; combined with Jieli Technology’s Beijing Stock Exchange listing in mid-August, domestic RISC-V/chip design companies are accelerating their connection to multi-tier capital markets.
  2. Server track advances further: StarFive Dubhe-100 moves from “release” to “official delivery” (China’s first server-class RISC-V CPU IP to reach deliverable status), with XIAO confirmed as an adopter; echoing SiFive BigSky delivery (reported yesterday), both international and domestic lines of RISC-V server CPU IP are moving from silicon design to customer project deployment.
  3. Domestic team engineering cadence: Sophgo releases pre-release security hardening for sophon-tools (5 commits including SophLiteOS v2.2.6); XiangShan advances KunminghuV2 performance regression CI and Deterload H/V support; SpacemiT and Revyos continue documentation and firmware iteration—leading teams are entering the deep waters of mass-production support and verification toolchains.
  4. Open source ecosystem policy: The OpenAtom Zijin Zone OPC incubation action plan lands in Suzhou, with the RISC-V open source chip industry innovation center listed among five provincial-level platform pilots, supported by a 1 billion yuan-scale OPC industry fund matrix and a 30 million yuan AI micro-seed fund—open source chip incubation gains dual support from local policy and capital.
  5. Embodied intelligence: No new RISC-V hardware in this window; M-Robots OS 3.0 Beta (OpenHarmony robot OS) shifts to swarm intelligence, and the Shenzhen embodied intelligence expo saw 390 million yuan in deal intentions over 3 days—industrial scaling is underway, with RISC-V penetration still led by ecosystem and middleware layers.
  6. Limitations: gnews Chinese team queries remain noisy (“XiangShan” matches Beijing Xiangshan Forum, “Sophgo” matches gambling/automotive content, “Milk-V” polluted by tokenization); SiFive when:3d query returned empty; GitHub search constrained by unauthenticated rate limits used single commit search, with deep-dive granularity based primarily on commit titles.
