From black technology to super engineering

Chapter 51 You Forgot the System

Professor Chen was taken aback by Ye Ming's question.

Because... this question is very unstandard, even a bit civilized.

As we all know, there are several big "hooligans" in the field of computer science.

For example, talking about design out of requirements, technology out of scenarios, architecture out of ecology... These are all hooligans.

Ye Ming's question is a bit like breaking away from the ecological framework.

But Professor Chen was only taken aback for a moment.

After all, he knew that Ye Ming's knowledge of accounting was very solid.

After pondering for a moment, Professor Chen smiled slightly: "If you enlarge your question to the entire electronic circuit, instead of simply referring to our personal computer system, then the answer is obviously yes, because assembly language is not required for embedded development."

"That's where the definition of assembly language comes in -- it started out as an upgrade of the old computer machine language, and then it became a symbolic description of processor instructions."

As he spoke, Professor Chen picked up the chalk and began to draw a simple PC architecture on the blackboard.

"When we started learning assembly, we talked about computer systems, from machine language to assembly language to high-level language..."

Professor Chen didn't bother, and quickly explained the basics of computer architecture.

"...Here, at the system level, a new player has emerged—Android. Because Android is a framework built by JAVA, if you want to develop Android in the future, you don't need to master the 8086 assembly instructions and codes in the book. — but Android also has ARM-based assembly instructions..."

As the blackboard was full of writing on the blackboard, Professor Chen put down the chalk, picked up a towel and wiped his hands, and finally looked at Ye Ming.

"...so, let's get back to your question."

"For ordinary developers, if a system's development framework can be perfected, then machine-oriented low-level languages ​​are not necessary, such as Android development."

"But for systems and hardware, assembly language will not disappear, it will only exist in another form - because its essence is a bridge between data and processor communication."

"Of course, if you can develop a brand new processor architecture and match it with a brand new system, I think everything is possible."

Professor Chen looked at Ye Ming after a moment of silence.

"Have you made it clear?"

"Thank you, Teacher Chen."

...

After sitting down under Shen Ruhai's surprised eyes, Ye Ming asked Professor Chen the same question in his mind.

"Have you made it clear?"

"Make it clear."

"Then do you still want to design a system?" Ye Ming remained expressionless.

"I also want to design a processor."

"true or false?"

"real."

Ye Ming: "...What about the application scenario? What about the software environment?"

Ita replied calmly: "Brain machine."

The corners of Ye Ming's eyes shrank suddenly!

"Wait, we have discussed before, the most critical difficulty of brain-computer is data transmission..."

"There will be a solution."

Ye Ming: "...you can't always be whimsical."

"If the biological knowledge you taught me is correct and accurate, then I can understand that the biggest deception received by the biological brain perception is visual deception."

"Although I don't have an intuitive feeling about how you 'see' the world you are in, from your description, I can probably estimate the relevant scene."

Accompanied by Ita's voice, a stick figure appeared in Ye Ming's mind - this was "generated with the brain" when he depicted a human image for Ita.

Judging from the appearance, Ita probably thinks this is his image...

Immediately afterwards, all kinds of strange things began to form around the stick man, including but not limited to water cups, chairs, tables, mountains, trees, and other people...

"These things exist in your space. You perceive them through the organ of the eyes, and then convert them into nerve signals, and finally process them through the brain to generate pictures."

Looking at the abstract line drawings in his head, Ye Ming was sweating: "...Yes, and let me declare that the real world is not like this. I want to be much more handsome!"

"That doesn't matter. What matters is that vision is signal deception. If your world can manufacture tens of billions of transistors and circuits in a square centimeter, it should be able to manufacture chips and circuits that connect the visual nervous system. "

Ye Ming: "It's impossible under the current conditions..."

Ita's voice came calmly: "You forgot the system."

Ye Ming was taken aback for a moment, and he immediately thought of those material analysis and technological breakthroughs.

Is it really possible to make a biochip?

And if there is a biochip, then...

What more X86! ARM!

Tang Zhigao Laboratory.

Yang Chaoxiong, as the number one leader of Professor Tang's new project, naturally assumed the responsibility of the team leader of the project preparatory meeting.

So, Ye Ming's experimental design draft fell into his hands, and he discussed it with his brothers and sisters.

"Brother, let me first say that I am a layman with brains and computers, but Ye Ming's report seems feasible." Guan Hai, who is about to graduate, is turning the pen skillfully with his right hand, and his eyes are fixed on the notebook: "In the past half month, we have written There are many related papers, and you can see his design, the reference electrode when collecting EEG signals, he does not use the grounding scheme, but the scheme of taking electricity from the earlobe to form a differential circuit."

"This kind of solution is also the current mainstream solution, but we can't get other people's denoising algorithms."

Yang Chaoxiong nodded expressionlessly: "As far as the algorithm is concerned, Ye Ming is very sharp, we have all seen it before."

Hearing this, the group of people laughed at the same time.

Brother Yang Chaoxiong is a doctoral student, but Ye Ming, an undergraduate, pretended to be B, and he was very depressed...

But fortunately, Ye Ming's attitude is modest and he didn't talk much about Yang Chaoxiong's code. He just carried out algorithm iterations - those who can win, everyone has to accept it.

Therefore, everyone didn't have any special views on this junior who the teacher valued very much.

At this moment, the door was pushed open, and Professor Tang Zhigao walked in.

"How's the discussion going?" Professor Tang asked, pulling up a chair and sitting next to Yang Chaoxiong.

"No problem on the whole." Yang Chaoxiong nodded after thinking for a while: "After all, I admit that Ye Ming is still very rigorous in his work. It's just that he didn't write about the equipment purchase and other detailed plans."

"Well, after all, people's energy is limited." Professor Tang looked at everyone with a smile: "That means, can you let him mess around?"

"Teacher, it's okay to try, the equipment is really expensive..." Yang Chaoxiong looked back at the instructor: "Let's not talk about anything else, a GAMMABOX signal instrument from g. easy to find."

Professor Tang frowned slightly.

Everyone fell silent.

Buying equipment before applying for funds means that the laboratory pays for itself...

But everyone also knows that there is a reason why Professor Tang wants to develop brain-computer + AI + wheelchair.
