On August 2, the second phase of the NH Tech Salon (New Helium Technology Salon) held at the New Helium Brain Intelligence was successfully concluded. This salon event invited King Zhu, who worked at Analog Devices (ADI) and Microsoft. He graduated from the Massachusetts Institute of Technology (MIT) with three and a half years of undergraduate and master's degrees in electrical engineering and computer science (EECS). In this issue of the salon, he shared the theme of "The development needs of AI chips and existing solutions".

At the event, King Zhu introduced it as "History of AI Development". He mentioned, "From the term" AI "was formally proposed in 1956, to the rapid improvement of BP algorithm and the explosion of data, and AI has entered again in recent years. During the prosperous period, everyone can find artificial intelligence in various industries and rapidly develop and change people's lives. "By sharing his life experience, King Zhu allows everyone to feel the power of AI more closely.

Subsequently, King Zhu pointed out that in the AI application scenarios, "cloud services", "cameras", "robots", and "IOT" have relatively more applications for AI chips, and the largest application scenario for chips is "cloud servers." The results of the rapid development of AI chips are also reflected in various application scenarios. King Zhu explained that the more important the AI chip is in the application scenarios and the greater the challenge to the hardware, he introduced three cases to the guests. And explained with simple and clear data, at the same time King Zhu pointed out that the high requirements of AI chips for hardware are divided into three points: high computing power, high efficiency and low price. He believes that it is possible to "define how to design the hardware through the requirements of software", and through explaining the bottleneck of AI algorithm and von Neumann to explain to the guests that data transmission requires large power consumption.

King Zhu said that in the second golden age of computer architecture, in order to achieve the goal of "high computing power, high efficiency, and low price", it can be achieved through the improvement of three methods:
1) reduce the amount of transmitted data;
2) accelerate the transmission speed;
3) Parallel computing.

Based on the background mentioned earlier, King Zhu shared five AI chip solutions for the live guests, and highlighted the highlights of these AI chip different solutions through different types of cases to make it easier for guests to understand the different The essence of the solution.

Among them, "AI hardware new technology solution" is the direction that King Zhu deserves attention. He introduced to the guests on the scene three new technologies that he believes have great potential for expansion and development:

1) The emergence of analog computing has greatly affected AI hardware. It saves power consumption and improves speed, but poor accuracy and poor scalability are also problems that need to be overcome;
2) Optical operation is calculated by light, and the speed of light is not much different from the speed of electrical propagation, and Perfectly overcome the heat dissipation problem;
3) Brain-like chip is a sustainable training technology. Pulsed Neural Network (SNN) launches models through neurons, and the memory requirements are also greatly reduced, thus greatly reducing the training time.

Regarding the future development trend of AI chips, King Zhu believes that smart cars will be popularized in the future, and AI chips can provide processing and judgment in real-time road conditions to make road traffic more smooth and orderly. At the same time, King Zhu believes that in the future of intelligent voice and intelligent robots, there will be a greater improvement and better services for humans. At the event site, King also gave some future prospects in different directions, and believes that there will be AI chips where there is AI in the future. Perhaps in the future, AI chips can be used with CPUs and GPUs to become another type of electronic equipment. Processor.

From the event to the interactive question and answer session, the guests put forward their understanding and confusion about the AI chip. King Zhu answered the questions one by one. The guests all said that although the time is not long, they have achieved a lot. Finally, under the guidance of the staff, the participants took a group photo with King Zhu, and jointly wished that the new helium brain intelligent salon event could be better and better!
