Arrangement ｜ Wu rouying

RISC-V It is a kind of..., which has sprung up in recent years CPU New architecture , Because of its openness 、 Flexible characteristics have gradually become a popular choice in the semiconductor industry . At present , Already near 2500 I'm going to join RISC-V The foundation , Including ali. 、 Huawei 、Google、 Intel 、IBM Companies such as . In Alibaba, it was announced that pingtouge opened the source of xuantie RISC-V After the series processor , Through opening a series of tools and system software , Push RISC-V Architecture matures , help RISC-V Development of software and hardware technology .

2022 year 7 month 21 Japan , Sponsored by China open source software promotion alliance , Sadie media 、《 Software and integrated circuits 》 Co sponsored by the magazine ,CSDN Exclusive live “ The 17th open source China open source world summit ” On , Ali Flathead CPU Head of technology ecology 、RISC-V Chen Wei, vice chairman of the software Committee of the international foundation, shared with “ Xuantie Kaiyuan , structure RISC-V Inclusive ecology ” A speech on the topic .

The following is the transcript of Chen Wei's speech ：

Hello everyone ！ I'm Chen Wei , What I want to share with you today is 《 Xuantie Kaiyuan , structure RISC-V Inclusive ecology 》.

RISC-V The background and development of

stay RISC-V In the context of development , Computer technology can be divided into four stages ：70 The mainframe era in the early s ;90 The Internet age in ; Mobile Internet era of smart phones and computers ; Nowadays, the era of Internet intelligence with multi terminal devices .

Vertically , More and more devices are moving from the cloud to the edge .

Horizontally , With the advance of the times , Computing power has been significantly improved . Mapping to the development stage of the entire processor , The way of interaction in different stages 、 Architecture 、 Application scenarios have changed significantly . stay AIoT In the application scenario of ,RISC-V Instruction sets have become popular .

from RISC-V The development process of ,2016 Years ago , Basically complete the structure in the school .2017 After the foundation was established in , With Industrial Synergy , Developed 32 position 、64 Bit basic instruction set ,2020 Years later, with the compatibility architecture , There are more advanced SoC appear , The whole software ecosystem is getting richer .

RISC-V Technology is a trend of accelerating development , It takes ten years to complete the traditional structure 20 In the course of .2019 year 10 Of the month 《 The economist 》 The magazine has a prediction , Open source software is a prerequisite for the great development of smart phones in the past decade , and RISC-V Such open source hardware may allow other devices to achieve similar expansion in the next decade .

RISC-V The number of members of the International Foundation has exploded in recent years . At the application level ,RISC-V CPU core The market is growing fast , Reached 115% About a compound annual growth rate . Predict 2025 year , stay IoT、 There will be a significant increase in the industrial and automotive markets .

 RISC-V Advantages and challenges of productization

Pictured above ,RISC-V Open source products bring many advantages , It also brings many challenges . in general , Many companies are involved in these areas , Also concentrate on solving these problems .

Brother Flathead is RISC-V Work at the foundation level

• Top member of the foundation . As a member of the board of Directors , Members with voting rights ,TSC The committee .
• High technical participation . There are 60 Technical groups , Brother Flathead participated 1/3, Include 8 The work of the committee .
• High ecological participation . Pingtouge and global partners jointly establish RISC-V Software ecology of , Active support RISC-V Various meetings of .

RISC-V International Foundation Technology Architecture

    RISC-V The current overall structure of the international foundation is TSC The Technical Steering Committee is the main , coordination CTO、Staff Work , Each committee has more than a dozen technical working groups . In the software committee , The recent expansion is divided into two committees ：Privileged Software The committee 、Applications & Tools The committee . at present , They are responsible together 39 The work of technical groups .

Open source technology 、 Contribution criteria 、 The concept of inclusive ecology

Brother Flathead upholds open source technology 、 Contribution criteria 、 The concept of inclusive ecology , Actively promote work in the community , It is mainly reflected in five aspects .

• Dark iron CPU Open source

Darksteel IP The product line mainly provides low 、 in 、 High three series of processor products ： The low end is marked with XT902 As a representative , At the hardware level TEE aspect , Protect sensitive resources , Greatly improve security . The middle end is marked with XT906 As a representative ,AI Vector engine supports chain acceleration , Calculate bandwidth improvement 50%. High end XT910 As a representative , It is the first commercial multi launch disordered storage architecture RISC-V, Main frequency up to 2.5GHz.

• Sword free SoC Open source of chip design platform

Wujian series mainly provides chip architecture 、 Basic software 、 The overall solution of algorithms and development tools . Sword free platform is based on architecture 、 operating system 、 Software drivers 、 Modular components such as development tools , Basically undertaken AIoT chip 80% General purpose work , It allows people who really do chip development to focus on Design .

• YoC Basic software platform

Software is very important in the whole open source environment , We focus on tools and basic software , Support mass production .

• Sword pool CDK development environment

Cloud integrated development environment CDK, Work through remote development and testing , It can provide developers with standardized test beds 、 Support unified services , Reach all resources .

• OCC The inclusive ecology and construction of chips

Open community of chips OCC, It can provide developers with a variety of solutions , Provide assistance in some specific ecological construction directions , for example ： bluetooth BLE The ecological construction of 、Wifi+TEE Safe ecological construction .

future RISC-V Development direction

future ,RISC-V The development direction of technology products will focus on four aspects .

• Wireless and MCU.RISC-V We need to build on our existing advantages , Achieve low cost and AI The blessing .
• Industrial control and vehicle . In the national strategic requirements , And the industrial control and on-board requirements should be driven by autonomy ,RISC-V Can develop high-performance real-time series .
• Voice and HMI.RISC-V Need to be in BSP、AI The ability to improve , At the same time, in the cloud AI The system should be continuously invested .
• Intelligent vision and edge computing .RISC-V You need to improve your computing power 、AI The blessing , At the same time, we should reduce costs .

Brother Flathead took three years , Finished xuantie RISC-V Full chain open source .

future , We have three visions ： First, the technology is leading , Especially in the formulation of international technical standards ; Second, ecological guidance , There are more rich applications available to the community ; The third is to achieve inclusive and win-win , Only commercialization driven applications are implemented , Will promote ecological prosperity . Through the formulation of Standards 、 Industry university research cooperation 、 The cooperation of ecological partners in exchange for more developers to join the team , Jointly promote the prosperous ecosystem of open source chips .
