Chapter 79: The True Strength of the Monster Little Junior Brother
"I know, big brother."
"Then you should follow Senior Sister Bai first! She is mainly responsible for simple design and debugging work. Let her take you through a little bit of instruction set basics. ”
Su Han nodded, came to Bai Di's side, and pulled a chair.
Bai Di said: "Designing hardware that meets the requirements of the instruction set is a very complex and delicate work, which involves a lot of knowledge to build the underlying logic of the computer, and I can't understand it in a few words. The Rics instruction set we are using now. is an open-source instruction set. However, although it is open source, we have not yet fully grasped the application of this instruction set, and our research topic is to design our own computer based on Rics. If you don't understand it for the time being, don't worry, as long as you are willing to work hard to learn, you will be able to understand sooner or later. ”
"I know, senior sister."
Bai Di nodded, and then began to busy his work.
Bai Di, who entered the working state, quickly immersed himself in it...... It seems that he forgot that there was a person sitting next to him.
It didn't take long, and a difficult point quickly stumped Bai Di.
made her frown.
Repeated debugging data is also not normal.
"What's the problem?" Bai Di muttered a little.
Su Han suddenly interjected: "The above calculation range is set incorrectly. ”
Bai Di said reflexively: "How should it be set?" ”
Su Han said: "-5, 8. And there is a 2 less after add. Because 2 stands for to. Otherwise, it will be misrecognized. ”
Hearing this, Bai Di hurriedly made modifications, and in a test, sure enough, everything met the conditions.
"Huh! Don't say it, you're quite powerful, you can ...... at a glance," Bai Di said this, and suddenly felt something, and hurriedly turned his head to look at Su Han, his expression full of surprise.
"What's the matter, Senior Sister? What are you watching me do. ”
"Little junior brother. Can you read the instruction set? ”
"A little bit!"
Bai Di's face showed suspicion, and he casually pointed to a string of characters and said, "What is this?" ”
"Unconditional Jump in Jump Command."
"What about this?" Bai Di pointed to another one.
"Principles of Alignment and Backward Expansion."
"What about this?"
"Function instructions represent the amount of movement."
"Isn't it! Why are you so powerful. ”
"Just a little bit of it."
"That's a little bit of understanding. You're better than me. Feed! Come on, everybody. ”
Hearing this, everyone got up and walked over.
When Bai Di told everyone what had happened.
Everyone was suspicious.
Can an undergraduate student understand the instruction set?
Really?
Of course, He Liang didn't believe it.
How can a freshman undergraduate be so awesome.
He Liang picked out a lot of difficulties in the instruction set, and began to test Su Han.
Su Han answered the question fluently...... There was hardly anything he didn't know.
The more the crowd listened, the more frightened they became.
The more I listened, the more shocked I became.
The last one was in disbelief.
Of course, He Liang didn't believe that Su Han was so awesome, but several questions didn't stump the other party. Then he gritted his teeth and wrote down a series of instruction syntax for his design and compilation at this stage.
After reading it, Su Han said, "This is a simplified fragment of a register. And you're doing it wrong. A Q should be added to the end to indicate parallelism. Otherwise, the hosting process will be too complex and take up more system resources. Shouldn't the design idea of a reduced instruction set be more lean? ”
Everyone was completely stunned when they heard this.
No way!
Where the hell did this guy come from?
He Liang didn't expect that the stage results he had worked so hard to get out would not only be seen through by the other party at a glance, but also saw a loophole.
Seemingly feeling a little unconvinced, He Liang changed and redebugged the command.
After testing, the results were exactly the same as Su Han said, the efficiency was greatly improved, and a lot of resources were saved.
Everyone looked at each other, and the atmosphere in the room suddenly became a little weird.
……
Bai Di said: "Little junior brother! Where did you learn all these things? ”
Su Han said: "Self-taught." Don't I have a computer at home? Sometimes I also design my own instruction set to play at home. Just pass the time! ”
Design your own instruction set to play to pass the time.
Everyone would be completely dumbfounded.
How can such an awesome person exist in the world.
Isn't he a freshman in high school?
Could it be that the other party is attending a space university?
……
Wei Haoguang pushed the door and walked in at this time. "Everyone is just right. In the past two days, Su Han and I have studied the instruction set we have designed. There is a big problem with the train of thought. It should be overhauled and adjusted. Therefore, the focus of the next stage is to overturn the compiled instruction set and re-modify the design. And also! Su Han's command set level is higher than yours, and he usually has to communicate more with his junior brother to improve his business level. Did you hear that? ”
"Hear this!" A few people reflexively said.
However, looking at Su Han's eyes, all changed.
It turns out that the other party is not pretending to be awesome, but really awesome.
No wonder the teacher is willing to let the other party go straight to the doctor!
It turns out that the other party is a computer monster at all.
It seems that there is an amazing computer genius on the team.
……
The next whole week.
Su Han helps everyone to revise the design ideas and research results in the laboratory every day.
Su Han had in his head how many generations of reduced instruction sets and chip design drawings would follow.
Naturally, there is no end to knowing everything.
Although the most advanced version,Subject to the current hardware,It's not used yet.,But some of the compilation ideas,It's not comparable to the current era.。。
Therefore, for the entire laboratory, the research results of three years are not as fast as the progress of the week that Su Han joined.
In the end, there was no one in the whole experiment who was not convinced by Su Han.
Self-study can reach this level.
It is not too much to say that it is the first super student in the history of the Mushui Computer Department.
In the end, even the senior brother He Liang was not convinced.
Of course, what makes him even happier is that because of Su Han's joining, his level has also improved significantly, he was still old and worried, there was no breakthrough in his thesis, and he couldn't finish his studies when he was old.
It's good now.
The dawn of graduation is getting closer and closer.
Several other people were even more affectionate to Su Han.
After all, there is such a genius junior brother to carry the banner, and they will also follow it.
But they'll be able to see it.
The Su Han family is definitely a tyrant-level existence.
Because Su Han actually has his own phone.
Tens of thousands of dollars in phone calls are still unimaginable for ordinary people in this era.
Genius or not.
It's okay to be a local tyrant.
For several people, there is absolutely nothing wrong with befriending Su Han.
……
Su Han came to Wei Haoguang's house this time, because the master was looking for him.
Zhou Yiru said with a smile: "Su Han is here." Come and sit. Let me introduce you to it. ”
Zhou Yiru turned around and introduced a man and a woman to Su Han.
The man's name is Deng Chengli.
The woman's name is Feng Yan.
