生态进展
国际峰会:
进迭时空携手 RVI 亮相 OSS/ELC NA 2026
进迭时空参加 Open Source Summit + Embedded Linux Conference North America 2026 ,并在同期 RISC-V Insights Mini Summit 进行了 K3 硬件能力与开源生态主题分享。
项目案例:
进迭时空 K1 落地荷坳水厂,实现 RISC-V + 鸿蒙 全栈自主智能化升级
进迭时空联合吉斯凯达、中国科学院软件研究所,基于自研 RISC-V AI CPU K1 完成深圳荷坳水厂"鸿蒙化 2.0 升级"项目。方案以基于 K1 的鸿蒙智控器替代传统"PLC+网关+边缘设备"组合架构,实现从底层芯片到上层工控软件的完整鸿蒙化体系。
X200:
进迭时空第三代高性能 RISC-V 处理器核 X200 正式完成研发 。相比X100,最新一代X200 在单核性能、向量计算、访存系统、多核互联、虚拟化、安全与RAS 等方面持续提升,单核性能达到 16分/GHz@SPEC2006 Int。X200 针对Agent 计算机(Agent Computer)、迷你 AI 超算(Personal AI Supercomputer)、具身机器人、云计算等场景进行了专项优化。
K3 shelf:
K3 真机编译效率提升 10 倍
对于依赖 QEMU 仿真进行 RISC-V 开发的工程师而言,进迭时空 K3 提供了一个更高效的选择。实测数据显示,K3 真机编译相比 QEMU system-mode 提速 10 倍,以 Linux 内核 6.18 为例,编译时间从 3.8 小时缩短至 22 分钟。
