In the IT sector, CPU chip and operating system is the most basic network in the letter the field core technology. But in chips, high technology and capital threshold, the most widely used instruction set architecture required to obtain patents can be used, such as x86, Arm and so on. The R & D investment to 14nm technology, for example, need a billion dollars in research and development costs.
Study how to reduce the threshold of the chip? Was known as "the semiconductor industry Linux" open source instruction set RISC-V is probably one of the important help.
January 13, China Eco-open instruction (RISC-V) Alliance 2019 Conference and Wuhan research Innovation Forum was successfully held in Wuhan. Wuhan RISC-V production and research base, RISC-V sub-center coalition Wuhan, Hubei and Xing RISC-V in production and research base inaugurated the conference .
At the meeting, Chinese Academy of Engineering, China Eco-open instruction (RISC-V) Alliance chairman Ni Guangnan represent "the future of RISC-V is likely to become one of the world's mainstream CPU, thus forming Intel in the CPU field, Arm, RISC-V-thirds the pattern of the world. "
Ni Guangnan so why say? RISC-V What are the characteristics?
RISC-V architecture is simple, modular support
RISC-V is a RISC (Reduced Instruction Set Computing, reduced instruction set) fifth-generation version. The Turing Award winner, Professor RISC inventor David Patterson in 2010, led by the University of California, Berkeley team took three months to complete the initial design and development of RISC-V instruction set.
According to Ni Guangnan introduced, RISC-V is based on the widely used and very loose standard BSD license, developers can freely free to use RISC-V is designed CPU, develop and add its own instruction set to expand, choose whether public offering or commercial sales, or replacement of other license agreement, or completely closed source.
Thus, the advantages of RISC-V is very significant:
1, lower capital threshold chip design.
Input costs of traditional chip design of large human and financial resources, may need to put hundreds of people in the team and funding a billion dollars to develop SMEs prohibitive. The open-source chip design reduces chip design threshold, only a few million, a small team of 3-5 people within 3-4 months will be able to develop a chip for their own business, in favor of small and medium entrepreneurship needed to promote chip development of the industry.
2, simple architecture that supports modular.
RISC-V current molding technology code set small, simple structure, basic instruction set only 40 pieces, plus other modular expansion command a total of tens of instructions. RISC -V support modularity, superior performance to meet the needs of all types of processors from microcontrollers to supercomputers. And to support the implementation of FPGA, ASIC and future devices.
Because RISC-V With the above advantages, the broad market applications: According to analyst firm Semico Research released "RISC-V Market Analysis: Emerging Markets" report data, 2025, the market will be spending a total of 62.4 billion RISC-V CPU kernel, which is expected to be the largest industry segment, with 16.7 billion kernel.
All things Internet era, RISC-V ushered in opportunities
With the advent of the Internet era of all things, domestic and foreign numerous machine and system manufacturers have the chip layout area. In this conference, the Ministry of Industry Institute for Integrated Circuits Research Institute CCID senior analyst kinds Dandan introduced the Road, Apple's self-development A series processors used in the iPhone, with plans in 2020, using a self-developed chips on Mac ; Google self-developed artificial intelligence ASIC chip TPU, applied AlphaGo system; chip Amazon has a team composed of 449 employees, a new generation of self-developed chips used in Amazon Echo intelligent speaker; Facebook recruiting semiconductor R & D team, its self-developed chips use hardware products, data center servers.
In China, relying on Huawei's HiSilicon, Kirin developed a variety of series phones SoC chip, chip and release Kunpeng Tarzan server; Alibaba set up grub brother semiconductor, issued based on RISC-V Xuantie series processors; Baidu released the first self-developed full-featured cloud models AI chip "Kunlun."
Looking back at history, we find in the PC era, x86 architecture spawned Intel and other companies; in the mobile Internet era, Arm architecture gave birth to Qualcomm, MediaTek, Arm and other enterprises; and now into the IoT era, generally agreed that networking and edge computing may be a RISC the greatest opportunity -V development.
It introduced species Dandan , intelligent hardware products rely on the CPU of Applied Ecology, the performance is lower than the PC, mobile phones and other products, x86, Arm traditional strengths CPU architecture can not fully play; In addition, intelligent hardware products for the CPU power consumption, size cost and highly sensitive part of the RISC-V architecture with embedded CPU than similar Arm, x86 architecture CPU lower power consumption, smaller area and lower prices.
Turning to RISC-V opportunities in the era of things, and before CSDN interview Patterson outstanding students, student RISC-V one of the key founding team, deputy director of the laboratory RIOS Turing Award - Tan Zhang Xi, he also talked about the same point of view: "In the emerging markets, we also make a new choice, RISC-V has the flexibility, modularity, openness, safety advantages, will become the first choice for many people, such as in the field of things, because things device fragmentation, demand very diverse, we need to be very flexible architecture to adapt to it, RISC-V according to different user needs, but also increase their own instruction set extensions to increase the expansion module. "
Eco-development proposals
On the one hand the diverse needs of emerging markets, but on the one hand we are facing integrated circuit talent gap is large: According to the "White Paper on China's IC industry talent (2018--2019 edition)" The data show that as of the end of 2018, China's IC industry employees size of about 46.1 million people, is expected to 2021, the scale of the whole industry talent demand of 72.2 million people, 26.1 million people in the middle there is a gap.
And in 2018, the IC industry's voluntary turnover rate was 14.3%, integrated circuit industry average monthly salary of 11,130 yuan.
How to better develop and retain talent related?
In this regard, kind Dandan make a few suggestions:
1, accelerated processor talent introduction and development work:
(1) from the Recruiting establish long-term incentives of development talent and his team for the introduction of new instructions;
(2) from the left only on personnel policy to explore multi-dimensional, as settled and other measures;
(3) from the Yucai, training school-enterprise cooperation, combining teaching and research are encouraged to chip in theory and practice. Religions play and integrated circuit production and the development of open and positive role in China instruction ecology (RISC-V) alliance and the like.
2, RISC-V industrial ecology construction:
(1) strengthen the open-source chip R & D support, through special research projects supported RISC-V chip IP core development, to provide domestic chip performance levels.
(2) enterprises to actively participate in the open source community RISC-V-related work.
(3) to encourage the industry chain upstream and downstream enterprises to form a virtual IDM set architecture around RISC-V and other new directive (Integrated Device Manufacturer, integrated component manufacturer) alliance.
(4) RISC-V-related industry alliance to promote cooperation with universities and other related businesses, such as promoting the construction of community standards and technical specifications of the system, and gradually build industrial ecology.
Today in Wuhan, the establishment of China's first RISC-V production and research base, and Wuhan as the world's largest number of students in the city, I believe will add more young innovative strength RISC-V ecology. The future can be expected.
