January 2015-January 2016, University of Texas at Austin, Research Fellow (postdoc). November 2009 -September 2014, Assistant Researcher, Institute of Software, Chinese Academy of Sciences.” When the editor saw such a wonderful personal resume, he was actually worried about the results of this interview. Sure enough, he abandoned the natural barriers of liberal arts and sciences. The dimensionality reduction caused by the difference in academic and professional abilities caused the editor to lose a lot of hair in the final draft of this interview. Under the conditions of listening to the recording while looking for industry-specific abbreviations, the manuscript was finally completed. Today, let me come to Pengfeng Technology and learn about **Zhang Xianyi, CEO and co-founder of PerfXLab.**   The true feeling is not forgetting the original intention. A person's life will play many roles, being a son and a daughter, a wife and a husband, and a father and a mother. The dreams of childhood, the pursuit of youth, and the aspirations of old age, along the way, some people may gradually lose, or some may give up halfway; but the true feelings are not to forget the original intention, to retain the truest self in my heart, and to protect them silently. Wait, persist, pursue, and finally try to be outstanding. Zhang Xianyi is a person with real feelings. Through his brilliant personal resume, through this interview and communication, he can feel the persistent pursuit of technology revealed in his bones. ------------ The following content is derived from the recording summary during the interview: - Q: "Did you have the aura of a schoolmaster since you were young?" A: "I don't think I am a schoolmaster. Since I was a student, I prefer technology. After work I have also been doing technical things." - Q: "I am about to start my own business for five years, what changes have been made in my mentality?" A: "Pengfeng is a company that does a low-level computing technology software stack. This direction is closely related to computing hardware. There is a certain distance from the application side. In the case that China’s core technology in the computing field is still heavily dependent on imports, the commercial implementation of the computing software stack is still quite difficult. The Sino-US friction that began in 2018, China’s chip, AI, HPC. In the context of the pursuit of autonomous and controllable computing hardware technology, the computing technology software stack has also ushered in a major development opportunity. In the past five years of entrepreneurship, there have been confusions and difficulties in the process, but we have always upheld our original intention and insisted on doing what we think is valuable. Today it seems that this is quite correct. - Q: "How to understand Pengfeng's business from a more popular perspective?" A：A: "The computing software stack we made belongs to the core middleware in the technical system. It is at the same technical level and has the same value as the operating system, and it also has ecological problems. The operating system solves hardware resource scheduling and user interaction, while the computing software stack solves complex mathematical operations. For example, vision, audio, and AI involve heavy and complex mathematical operations. An interesting phenomenon is that people hope that the operating system consumes as little hardware computing resources as possible, and the efficiency of the computing software stack is as high as possible. Usually, the computing software stack consumes more than 80% of the chip's processing power." - Q: "If you were to describe yourself in three sentences, how would you elaborate?" A: "First of all, it's a geek, geek; the second sentence, I've been doing things I'm interested in; the third sentence..." - Q: "You don't need to be restrained, a very personal description is fine." A: "Very personal?" Always on the way to lose weight, hahaha" ###### Geek, a fanatic of technology; things of interest, technology; more than an hour of interviews, the most frequently mentioned vocabulary in Dr. Zhang's mouth is "technology", if you leave it to himself sharing, maybe the third sentence will also be a summary of the state of technology-related or love of technology. When a person’s love for a thing covers his hobbies, pursuits, career and even imagination, our Doing your best to be good will only leave trust and waiting. Geeks, people who are fanatical about technology; things of interest, technology; more than an hour of interviews, the most frequently mentioned vocabulary in Dr. Zhang’s mouth is “technology”, if you leave it to himself Sharing, maybe the third sentence will also be a summary of the state of technology-related or love of technology. When a person’s love for a thing covers his hobbies, pursuits, career and even imagination, do your best to be good, and only trust and wait are left. ------------ #### Pengfeng Vision: To be the world's leading computing software stack company, and to empower the development of computing technology through open source software. PerfXLab is a leading domestic technology company focusing on computing software stacks, providing complete computing software stack solutions based on terminal platforms such as ARM/FPGA/GPU/RISC-V, including application algorithms, frameworks, and high-performance computing libraries, software tools, and related hardware boards, etc. Application areas: Mainly serve the industry's major customers in the computing hardware field, and develop developers, enthusiasts, and university education markets through open source concepts. The company's core technical members come from MIT and the Chinese Academy of Sciences, and have rich experience in underlying computing technologies. In addition, Pengfeng Technology strongly supports the open source community, leading the internationally renowned open source matrix library OpenBLAS (top three in the world), and contributing the OpenCL GPU code of the OpenCV project. In 2020, we took the lead in launching the RVBoards open source software technology organization, with the goal of enabling open source software to empower every RISC-V SoC. It is also the first to provide the RISC-V community with a cost-effective Perf-V development board. In the future, it will increase efforts to provide developers with more inclusive and better RISC-V open source hardware. ------------ #### Representative product: Perf-V development board Perf-V development board uses Xilinx's Artix-7 series FPGA, model XC7A35/50/100T-1FTG256C, 256-pin FBGA package. The development board provides a wealth of interfaces, including PMOD, Arduino compatible expansion interface, JTAG, UART, and the aforementioned HDMI, VGA, USB2.0/3.0, camera, Bluetooth, expansion board, etc. that can be expanded through the adapter board. The high-speed interface, flexible, convenient for evaluation and prototype verification. The specific board resources are shown in the figure below.  The Perf-V development board already supports a variety of open source soft cores and commercial company soft cores, with relevant materials and tutorials, rich interfaces, and a variety of application scenarios. - Q: "Are there any pain points or difficulties that I hope can be solved through the platform?" A: "It's still in the direction of investment and financing. Last year, because the business model was not fully understood, I didn't think about the relevant aspects, but one we have proved that our path is feasible in the past year, so there is still a need for financing. We plan to concentrate on preparing for the first half of this year. Although we can do it without financing, after all, the influx of capital can accelerate the realization of our ideals. ------------ <span style="font-size:24px;"> </span> <span style="font-size:24px;"> </span>
