At present, I am interested in the following: embedded (real-time) operating system UC / OS-II, UCLinux, VxWorks based embedded system embedded systems for embedded systems and related tools C and assembly mix programming and The related compilation knowledge General operating system principle computer network (mainly TCP / IP)
Some of the discontinued words of the research direction
Some people say that the only unchanged in this world is changing. I feel that myself has changed a lot in this year, and all aspects may be some or I don't realize. People are changing, and what they do is also changing. In the first year of graduate students, or in Guangzhou, I can't think of the current research direction anyway. At that time, the company was used, and the Unix, database, middleware, and also happy, feeling a little entitled, thinking about what is going to learn, what is going to work, and even what kind of company works in the future. The encounter of life is sometimes difficult to expect. Later, after returning to the school, it began to change, the boss made the study of smart cards. To Tell the Truth, I just started, I am very reluctant. I have always feel that I am not the child who is like listening, or it is called a master. But the boss is a person who is more changing than me, so it is still compromising, the opening issue has become a smart card. I don't understand smart cards, may know more than ordinary users, knowing that smart card generally refers to an IC card containing CPU and operating system, which is now. To this end, it is very painful for a while, can't tolerate what you study, staying in such a coarse state, and is not interested in it. I love thinking, the more painful thinking, and the time to study and study is so precious. At the beginning, I chose the postgraduate study, I think this science is too shallow, I want to see some books during the postgraduate period, do something. Two brothers let me get out of this confusion. They have a similar experience with me, and the previous year is doing information system development. Later, it is written in the paper, and it is also a smart card. Often communicate with the brothers, they actually have similar confusion, but they have found a better way. I want to come too simple, I feel that what is going on, I have to have a banner in front of the front of the door, write the things you have to do, and then try to do it. In fact, many times is not the case, or you can't do this in reality. I don't know if it is a real wisdom or a smooth, everyone can still make two different things together, of course, they are associated. The process of thinking and going to change is trivial, and I don't want to describe it. I recently listened to a friend who hobbed a Buddhist, I told me a truth. He said that we can't change something, but you can change your understanding. I don't understand the things of Buddhism, but I understand this reason, it is like I accept coffee than I have, in fact it doesn't change, it is me. Before graduating from undergraduate, I paid attention to the open source real-time embedded operating system UC / OS-II, because reading a series of articles on the "MCU and Embedded System Application", very touched, I want to engage in this area thing. After he took the award of the National Electronic Design Competition, he was arrested by a teacher to achieve his fuzzy control theory, and he was also done. Later he graduated from work, do SCANNER's software development, and did not depart from this direction. I have been directly engaged in the study of embedded operating system, read the source code of UC / OS-II, and made some analysis, but did not do it to make porting. At the time of the defense, I used the embedded operating system for a bunch of teachers to control the direction of the system software development. Since the teachers are all controlled, the controlled algorithms and assembly estimates are more powerful, and the possibility of operating systems can also understand Not so much, so I didn't ask me, let me pass. However, he thinks that it is more sweat, nothing to do, the only thing that feels comforting is some of the words that I have said in the past two years. These years embedded things, especially the embedded operating system.
Unfortunately, I have never started to study in Guangzhou. One is more than a year. It is a completely different thing, and then I have learned a completely different thing, and I spent a lot of energy and enthusiasm to learn those things. Perhaps it is a fate, I didn't expect to be an embedded aspect, but I have to write the banner of the smart card. I feel gratified is that later I use IAR's compiler to transplant UC / OS-II to Intel 196kc, which has made a lot of analysis and software simulation. When the board is almost successful, it is made up for regret, there are some gains. Compared to actual applications, UC / OS-II is still simple, so start learning vxworks and uclinux, which also have a lot of utilitarian factors, that is, I want to prepare for this work. I have seen some articles and introductions, I know that the application of ARM is relatively wide, so I started to pay attention to ARM, I have read several books, and then I bought a development board with my partners, and I do something above. I have recently encountered a lot of difficulties in VxWorks and Uclinux, still working hard. In the year of reading a school, I have gone a lot of courses, of course, I have also taken a lot of tests. Among them, it is more interested in databases and networks, read Larry Peterson and W. Richard Stevens, have some understanding of TCP / IP, and then I like to get on the network, I hope I can learn more later. Preparing OS examinations when you originate from OS, you have an interesting thing to study those algorithm strategies. Later, in UC / OS-II, you will become a code, which has become more interest. Later, I saw Tanenbaum and William Stallings. I feel very good. To engage in computer, OS estimation will continue. The future charm is unknown, I want to work hard to do what I want to do.
