Our scientific and technological innovation can be said to be vigorous. However, most of those innovations are behind foreign countries. Except for traditional Chinese medicine, it is impossible to find Chinese originality to be recommended. This phenomenon will make those who doubt the IQ of Chinese laugh. Can't China produce its own scientific originality at this stage?

Indeed, in the field of scientific invention and creation, we have lagged behind for quite a long time. However, in the decades of reform and opening up, we have studied hard, accumulated a considerable degree of scientific heritage, and many fields have moved from backwardness to the forefront, which is a fact for all to see. But unfortunately, almost all follow the research, with little or no pioneering scientific originality. Is it true that there is no scientific originality? no The scientific originality of Fengmao Lingjiao was ignored or shelved by those authorities in the vigorous tide of studying abroad, so that it did not get due attention. Since ancient times, good writers have been despised in China. Because of the lack of scientific research habits of mutual discussion and debate, it is difficult for people to hear and see even if there is originality. Now it often depends on how to identify it abroad, which makes those local scholars whose English is not good enough lose the right to speak. People seem to forget that only your mother tongue can make you think at will, and arbitrary thinking is the origin of scientific originality. Now, Chinese people really have groundbreaking inventions and creations. They don't write them in English and don't publish them in foreign English journals. Who will believe that they are earth shaking inventions and creations? The "Han Chunyu incident" in gene research has made us experience a sad process of innovation, which shows that what is published in famous foreign journals may not be right. On the contrary, what is published in Chinese journals today may not be rubbish! Do foreigners have to be notified of the great inventions and creations of the Chinese people? So, what else do we talk about occupying the commanding heights of world science?

After the reform and opening up, many scholars studying abroad have brought back many advanced science and technology. Do those Chinese who have not gone abroad and have the courage to explore have no achievements? Please allow me to explore this point with my personal experience.

I was admitted to the Mathematics Department of Harbin Normal University in 1977. Previously, he was a middle school teacher in the second division of Heilongjiang production and Construction Corps. Before 1977, due to interest, I found some higher mathematics handouts printed on black paper in the basement of Xinhua Bookstore in Luobei county and took relevant courses by myself. During the self-study period, I put forward my views on the continuity of real numbers, and submitted the manuscript to the Journal of mathematical practice and cognition. Although I was not hired, it stimulated my interest in scientific research. In early 1982, he graduated from the teacher class of the University and was assigned to Beijing. Later, he taught mathematics and computer courses at the China Institute of finance. Since teaching computer courses, I wanted to design and make a computer from scratch. In the process of developing computers, I feel that the so-called "complement system" is not perfect, and there are loopholes that can not be explained. In order to eliminate those loopholes and improve the theory of machine computing, I studied the "limit" theory and found the basis for accurate machine computing. In 2004, he published an article on the understanding of complement system in the domestic journal computer technology and application, which expounds the limit theory and makes up for the shortcomings of complement system. On the basis of this research, a book "Computer Principle Course" is compiled. In this book, the complete computer design method starting from logic circuit is systematically introduced, but it is only carried out from the theoretical level.

In 2005, I got the EDA software Quartus II by chance, and systematically designed an 8-bit computer using FPGA development board DE1. About in 2007, I completed the single chip microcomputer design of this computer with pads circuit design auxiliary software, named pmc110. Although pmc110 is an 8-bit computer, and the input depends on 8 switches and the output depends on LED and nixie tube, the basic functions that can be completed are complete. Pmc110 has its own operating system and instruction system, which can complete the program input and execution in the virtual space, and can accurately calculate the value of ultra long digits. Using the limited resources of FPGA, not only the required equipment such as CPU, memory, various registers and clock metronome are designed, but also the input buffer is designed, and the buffer has the function of editing with switches and buttons. In a word, the pmc110 I made is a complete computer (see Figure 1).

After the completion of pmc110 design, I realized that the era that individuals can design and make computers has come. If we could pay attention to complete computer design at that time, especially the design and research of computer core components, we would open up a new world in China and take a big step on the road to computer cutting-edge science.
