Zhang Zhidong smell speech was very excited, but in a blink of an eye, he put his hands on a bitter face. "Director Liu, we can’t always develop our hands!"! There are few computers! "

Zhang Zhidong’s face-changing technology finally made Liu Meijuan laugh "Ha ha! That’s easy. I’ll change the setting of the bs chip on the motherboard, and then we can install the windws95 operating system.
Just discuss with them the underlying structure of dolphin operation system! "
Liu Meijuan’s spirit has never been more exciting. She just lost her words and hurried to the factory.
Chapter seventy-five Unified framework
Since Liu Meijuan can modify the bis settings, of course, he knows the public bis settings very well. This time, it is not difficult. The motherboard should not change anything, just replace the bis chip.
Funnily enough, bis chip is a reader, and ra must be edited by a special software editor to make it the basi language, which is the computer language of the micro-hard company Laifa, but this is the scope of hardware engineers.
This is because the early brain and computer languages are very simple, and because of simplicity, such an important basic chip as bis setting must be simple bas language plus machine language, which emphasizes stability.
It is ironic that micro-hard tool software has produced a new operating system with micro-hard competition.
Let’s not say that Liu Meijuan returned to the factory in high spirits to revise the bis settings. He said that Zhang Zhidong took over his hand and twenty college software engineers discussed the underlying architecture of Dolphin Operation System.
"How many students are majoring in architecture?"
Zhang Zhidong didn’t talk about it all at once. He first found out.
Sitting straight in the office, five of the students stood up and motioned.
Zhang Zhidong saw that there were five students, and his face was smiling, and his hands were empty. "Good! Please sit down! Very good, with five of your classmates helping me, we are mainly responsible for architecture setting, and his classmates are responsible for stacking code. "
At this time, five students got up together, and one of them said to Zhang Zhidong, "Director Zhang, I’m sorry! We study hardware engineering, I’m afraid we can’t help. "
"well! I know you don’t belong to my management, but I can tell you that your company is about to develop a motherboard, and you have work to do. "
After the five hardware majors sat down, Zhang Zhidong said, "When it comes to the device, it is necessary for me to talk to you."
Our dolphin control system and the robot control system we will develop must have strong interactive performance, and some system structures should be able to save us a lot of research and development time, so we should consider the problems in a comprehensive way
First of all, we can confirm that our dolphin operation system is a closed-source operation system based on uni, similar to Apple as.
Therefore, we don’t consider its computer and manufacturer’s settings, and we don’t need to consider most computer peripherals, some data interface standards, design an excellent peripheral and optimize the technical interface.
This makes it much easier for us to start work.
Of course, we can’t be optimistic about this difficult battle
What functions should a good computer operating system do?
Windws95 graphics operation of micro-hard company has unified our research and development direction.
First of all, you must achieve what you see is what you get, and you don’t need that complicated ds operation instruction any more.
Second, we must have powerful multimedia functions.
This gives me a difficult problem.
That is, parallel management, that is, there are multiple requests that need to be processed by the central processing unit at the same time, which often leads to conflicts or interruptions, that is, crashes
Of course, Intel Pentium chips have multiple computing cores that can handle multiple requests at the same time, but we have to predict that there may be dozens or even dozens of requests happening at the same time.
There are two solutions, one is to prioritize, which requires us to make a setting, which is a big problem because we don’t know what software will be available in the future.
We can classify all kinds of application software according to the request level, buffer, hard disk, graphics card, card, pu, folder, etc. The more limit requirements, the first place, and so on.
The second is the virtual machine, that is, we divide the software of hard disk and other devices into various categories and folders, and all the software should run the virtual machine, so that even if a single process or software crashes, it will not affect its software operation and effectively protect the computer security.
Ann is the most important thing we must pay attention to.
Especially in the future, there will be various requests from outside the internet to access our dolphin brain and cloud disk. Many of these requests are malicious and want to control our computer with viruses.
Either massive access requests cause brain or cloud disk expansion, or data overflow is light, which will cause paralysis and burn out computers or devices.
So how can we judge these harmful visits?
Therefore, we must add a security judgment mechanism. For example, our own research and development software-generated access belongs to Class A, and its formal interconnection access belongs to Class B. Software-generated access that has not been certified by us is dangerous.
In case of emergency, send an alarm or warning text to wake up the computer owner.
At the same time, class A software is allowed to access it, and visual access is allowed.
This will not cause paralysis and achieve the purpose of safety protection.
Of course, in this way, we must establish an security database.
"
Twenty college students in Wang Yong talked with Kan Kan in front of them, and they also benefited a lot from a transparent talk from the framework to the security.
I can’t help but say that Zhang Zhidong is really gifted and has super foresight. You know, there is no such thing as the root, but he has foreseen that some interconnection will lead to some problems.
In 1995, the calculation system was not so complicated, especially the special bis setting in Liu Meijuan reduced the difficulty by N levels.
If the micro-hard windws95 operating system needs hundreds of thousands of lines of code, then the dolphin operating system may have one tenth.
Micro-hard company operating system and Intel company is chip are the same, and there are too many things, which makes the operating system more and more complicated and bloated.
However, the dolphin operation system is a new thing, so there is no burden except to consider the issue of upgrading the system in the future.
Of course, all this is inseparable from the technical support of Liu Meijuan. If there is no Pentium chip set instruction and professional algorithm to re-develop an operating system, we will start with it
The central processing unit and the operating system have never been separated, otherwise there would be no wine alliance.
Some people may say that the graphical interface is a patent of micro-hard company, and his concept will cause patent infringement.
The real graphic interface is a technology developed by Xerox in the early 1970s, and it has just passed the patent protection period. If the dolphin operating interface is slightly hard, it will not constitute invasion.
Chapter seventy-six Expanding the Law Department
An operating system architecture setting can also be said to be a super-large project, because there are many unknown situations, such as the future.
Zhang Zhidong’s courage to accept this large-scale unified development is based on his deep understanding of inu operation system, and he has studied various classical algorithms.
Combining with the new concept of micro-hard windws95 operating system, he has really had some creative thinking. What if he comes to be the chief architect of the system? Every technologist has his own dream.
Who knew that this opportunity came so quickly, and those genius ideas in his mind were still clear, so he just brought them.
In addition, some time ago, he has been learning from Liu Meijuan, and he has a thorough understanding of the company’s research and development of dolphin brain from the inside out. It can be said that he already has the conditions for unified research and development exercises.
