专访隼瞻科技创始人曾轶

专访隼瞻科技创始人曾轶:创新处理器设计方法学,降低芯片设计门槛|看见新力量NO.110

随着IoT、新能源、人工智能等前沿领域的崛起,各式各样智能化的产品和服务呈现井喷状态。芯片设计也随之出现了新的需求转向,尤其在处理器的选择上。从超低功耗的物联网芯片、高可靠性的车规芯片,高性能的多媒体设备芯片,再到高算力AI专用芯片,垂直领域(DSA)专用处理器芯片正在形成下一个百亿级的新市场。image隼瞻科技专注于专用领域架构DSA的RISC-V专用处理器解决方案。公司凭借处理器核、EDA处理器设计平台、跨平台软件生态移植方案的综合优势,为客户实现灵活而完备的IP定制开发。其产品涵盖高中低端,广泛应用于AIoT、DSP、5G网络、汽车电子、AI、高算力运算等场景。

2022年9月,隼瞻科技由曾轶,姚彦斌,张开明三位创始人在上海创立。

创始人曾轶在半导体行业有20年从业经验,曾加入意法半导体、Cadence、Synopsys、Codasip、睿思芯科等全球知名半导体企业。团队联合创始人、CTO姚彦斌博士毕业于中科院计算所,先后加入国内一线设计公司和安谋中国,在DSP处理器,RISC-V处理器以及ASIP平台方向造诣深厚。联合创始人、COO张开明先后毕业于浙江大学、北京大学微电子系和光华管理学院MBA,曾加入意法半导体和国内一线设计公司,任芯片设计工程师和战略市场部经理。

近年来,人工智能等技术飞速发展,算力成新型生产力,SOC行业从传统的IP搭积木模式向更激进的追求高算力、高能效的DSA模式转向,市场常见的通用处理器也开始频频受挫。曾轶介绍,很多终端客户在产品设计中都会面对通用处理器只能发挥其中一部分功能,无法“物尽其用”的情况,“比如只用到处理器30%的功能,70%的功能都是浪费的”。另外,通用处理器降低了不同产品间的差异性,显著削弱了产品的竞争力。因此,面向应用的专用处理器(ASIP)开始成为不少专用领域SOC芯片设计首选。

不过,处理器定制开发成本高、交付周期长、可编程/扩展性弱等痛点也始终存在。如何在保证高性能低功耗的基础上,使芯片具备优秀的可编程性和可配置性,并在成本可控范围内实现?隼瞻科技用“高端处理器核+智能开发平台+先进设计方法学”的DSA处理器解决方案为业界提供了全新的思路。

立足于前期细致的市场分析以及客户反馈,隼瞻科技基于RISC-V技术路线推出了全栈处理器IP家族,覆盖从低功耗IOT/车规MCU处理器,到高安全高实时性CPU处理器(车规域控制器,工控处理器,SSD主控,Wifi6主控),到多核高性能应用CPU处理器(多媒体,AI,PC,服务器)。

公司已发布首个RISC-V MCU处理器IP家族,包括首个RISC-V车规处理器IP产品Wing-M100A、多功能RISC-V车规处理器IP产品Wing-M130以及高性能RISC-V车规处理器IP产品Wing-M500三款IP产品。其Wing系列处理器核IP完全自主可控,并采用了DSA专用处理器设计思路,实现了ASIC级别的硅效率,达到性能、功耗、硅成本的最优解。

众所周知,架构和指令集定制是RISC-V公认的优势,但手工定制设计的高难度、繁复的工作量使得大部分芯片客户望尘莫及。如何简化设计流程,降低设计门槛成为EDA产品要面临的关键问题,隼瞻科技自主研发的ASIP处理器敏捷开发平台WingStudio应运而生。

隼瞻科技的ASIP处理器敏捷开发平台 WingStudio,可以通过高层次架构描述语言对目标处理器架构以及自定义指令集进行描述,并由平台内置的Profiler进行性能评估及迭代,从而进化出垂直领域优化的DSA处理器,并由平台Generator“一键式”生成完整的RISC-V处理器IP包(HDK/SDK)。

WingStudio的出现大大降低了RISC-V处理器设计的门槛,并为以RISC-V定制处理器为核心的SOC设计方法学带来了革命级的改变。在WingStudio的基础上,设计人员得以摆脱了RTL级别的繁复开发工作,更专注于架构和指令集的设计;其一键式的SDK生成引擎更是大量减少了软件工具链开发的工作量,显著缩减了处理器开发的人力成本。

隼瞻科技的WingStudio 为客户搭建了从设计需求到设计能力的桥梁。曾轶把WingStudio的功能形象的比喻为“给处理器做CT”。他解释,平台内部配置了多种人工智能引擎,包括GPT等大模型,能不断通过引擎的分析推导来测试不同的设计方案,并最终优化处理器的各项指标。

以隼瞻科技的处理器IP家族为“基胚”,加上客户的特定算法需求,再辅以高效的WingStudio平台化设计,最终,隼瞻科技得以帮助客户进化出符合特定应用需求的新处理器。

以芯片设计公司为主要客户群体,隼瞻科技的客户结构呈现橄榄型。

曾轶介绍,橄榄型其中一边的客户主要偏好低价格、低成本、低功耗,差异化程度低的处理器产品,这类客户数量众多,产品开发难度低。另一边则以华为、中兴等大客户为主,这类客户内部有很多处理器设计团队,希望有外部的工具来协助其处理器的开发,以起到简化流程提高效率的目的。针对这类大客户,隼瞻科技主要为其提供平台工具以及深度的技术合作。

而在橄榄型的中间,则以大疆等在业内占据一席之地,寻求更多创新发展的企业为主。曾轶表示,这类客户清楚自身的定制化需求,隼瞻科技会相对应的为其提供处理器核、处理器子系统的定制、平台工具以及专家计划等各类服务。

在曾轶看来,芯片客户对于其芯片设计的诉求主要体现在三个方面,分别是提升垂直领域的产品竞争力,拓展产品市场空间,延长产品寿命。围绕这三大核心诉求,隼瞻科技通过DSA处理器、SmartDMA技术以及复杂数据类型的支持,达到性能、功耗、硅成本的最优解,实现ASIC级别的硅效率,帮助产品不断提升竞争力。同时,其处理器自定义指令集和软件开发/调试包,可对数据通道,通信协议,数据接口灵活配置,实现CPU(甚至FPGA)级别的编程灵活性,大大延伸了产品的适配范围。而为了延长产品寿命,隼瞻科技的可编程处理器与硬件深度融合,能适应更多新协议,避免产品因为其他条件的更新换代而被淘汰。

现阶段,隼瞻科技还联合上下游伙伴企业共同推出了行业平台,集合各项资源来服务客户的芯片设计需求,“通过我们的平台,客户可以接触到所有的国产处理器IP”。而这种生态合作圈也是公司拓展客户的重要方式。

成立隼瞻科技前,曾轶深度使用过阿里云的产品,包括跨国企业邮箱、数据传输和数据存储、项目研发协同以及企业级VPN业务,对于阿里云的安全性和便利性深有体会。

此次参加Create@2023阿里巴巴诸神之战“智能制造赛道”全球挑战赛,曾轶与来自工业自动化、工业智能等领域的创业者们聚在一起,不仅对工控领域处理器的需求趋势等有了更深的理解,也积累了行业资源,为后续工控领域的产品设计和业务拓展打下了良好的基础。
