After a long period of twists and turns, I figured out the ins and outs of the matter, and I couldn't help but feel very distressed.

However, I don't have enough confidence in my processor for a long time, because after all, it is an experimental product, taking into account the domestic manufacturing capacity, many things (such as hardware multipliers) are subject to the size of the transistor, and the performance data seems to be scary, but the actual application is not much higher than those 8-bit processors of the same level.

It's really Khanna, I didn't expect that my castrated version of the processor could also enter Zhongnanhai, Cao Changjiu thought.

"You can't get out of it now, God really has eyes, I came here today to pack my things. Zhang Chi said with a smile.

"Haven't you already got the system and compiler, what else do you want me to do?" Cao Changjiu also laughed.

"Nonsense, who can read that thing. Zhang Chi Zhengse said, "Hurry up and follow me, and let you go back after figuring out the system." ”

"Well, it can be regarded as contributing to the country. "I couldn't do it for a long time, so I had to pack up my things and leave the room.

This time, they went to Peking University, and asked strangely for a long time, "What are you doing here?"

"The R&D team was stationed at Peking University, and Professor Yang Fuqing (I hope Professor Yang doesn't scold me ^_^) presided over the software development. ”

"Cut, what do you want so many masters to do, it's better than a group of obedient high school students. Long disdain, "Besides, are there so many masters?"

"Of course, you're the only authority on the processor you're designing. ”

When I arrived at the research and development base, I learned for a long time that the heroes from all over the world were true, and there were programmers from almost all walks of life, and a few of them were his students in Hong Kong.

Those who had listened to Chang Chang's lecture were surprised to see him, and they all stepped forward to greet him, saying that he must be Mr. Cao, which made Chang Chang very comfortable.

"Why are you here?" asked them for a long time.

"Respond to the call of the state and work hard to realize the four modernizations!" replied in unison.

“......”

"**, who is this? A nice voice drifted into the ears for a long time.

Looking back for a long time, it was a middle-aged woman with a southern accent, who seemed to have seen it, and it was estimated that it was Professor Yang himself.

I didn't dare to slack off for a long time, this is the senior god, I bowed and said, "Professor Yang is good." ”

"You're good, what a boy. Professor Yang helped Chang Chang and looked at Zhang Chi with an inquiring eye.

Zhang Chi coughed and said: "Let me introduce to you, this is Comrade Cao Changjiu, and he is also the core figure of our project. The processor of the 0521 microcomputer was designed by him. ”

There was an uproar in the audience, and no one thought that this seemingly weak teenager was actually the mysterious designer.

They are all program elites who were called up because of the 0521 project, but because the Lishan Research Institute made a microprocessor, it could not make ideal software.

At that time, they were also skeptical about the ability of the Lishan Research Institute, and they knew that the original designer of the 021 processor was nowhere to be found, so that no one knew enough about its details, so they were all very curious about it for a long time.

As for Professor Yang, she was even more surprised, she had heard that a young genius in computing had actually written a set of operating systems by herself, but she didn't have the opportunity to see it.

The software task of the 757 machine also has a division of labor at Peking University, and she has specially looked for a long-term system and compiler, and I feel that it is indeed very level, but I have never had the opportunity to communicate alone.

After Wang's death, Professor Yang could not find him after going abroad for a long time, so he deeply regretted it. However, the long-term system continued to be improved in the hands of Professor Yang, adding many functions and fixing many bugs.

I didn't expect to see me today, I was younger than I imagined, how could this not make Professor Yang happy.

"Cao Changjiu, the name is like thunder! I still have what you wrote here. Professor Yang said with a smile, "I didn't expect to be a child." ”

Cao Changjiu smiled: "I was originally a child, but I feel very honored to meet Professor Yang." This is true, who is not a programmer of the younger generation in China who has not been illuminated by Professor Yang?

Professor Xu Jiafu of Nanjing University and Professor Yang Fuqing of Peking University are the founding fathers of the Chinese computer programming industry.

Professor Tsui Ka-fuk has unparalleled achievements in programming languages and automation, while Professor Yeung Fu-ching is an academic leader in operating systems and software engineering.

When Bill Gate went to China, he also visited Peking University Jade Bird by name, believing that Professor Yang's project was a monument.

He has always been very respectful of such a person, and his words are respectful and polite.

"Since the original author has arrived, we have to teach us a lesson. ”

"Don't dare, everyone learns from each other. ”

In this way, he put aside his own affairs for a long time and joined the 0521 research and development team. He called the Hong Kong side and told him about the situation, and if he returned later, he would work overtime in Beijing with peace of mind.

For a long time, they also have their own considerations, and these people in the 0521 project are the elites of the software industry from all walks of life, and they are responsible for transplanting the existing software currently used in other systems to 0521, so that the 0521 microcomputer can accumulate a batch of software that can be used in a short period of time, which is indeed a quick way.

But it's a lot of work, and it's not necessarily the best.

I communicated with Professor Yang for a long time and put forward a new idea, which is to specify a national standard and standardize the operating system of 0521 microcomputer, and all software is in accordance with a unified format on the system.

The R&D team issues a fixed R&D schedule, arranging the software to be written according to priority, and striving to make the most used programs come out first, so as to alleviate the development pressure.

At the same time, the software writing is done according to the project, and all the program components are modularized to maximize the utilization rate, so that although the initial stage may be a little slower, but as soon as the assembly line effect comes out, the follow-up products will be continuous.

This rule was unanimously adopted when it was proposed, and no one doubted that it was conceived for a long time, and the policy was implemented without hesitation.

So what is the top priority? Chang has naturally come up with his own research results - videoform software.

Professor Yang is not too interested in the spreadsheets in the videoform, but he is very fond of the small text editing program that he has written for a long time, and he boasts that he has a long-term vision.

I was confused for a long time, so I asked why.

Professor Yang replied: "Text work requires this, although you write an English program, but the bottom layer is double-byte, a little change can be used to edit Chinese, isn't it very good." ”

It turns out that the English program displays letters, and only one byte of space is needed to represent all the letter symbols. And Chinese characters are not good, Chinese commonly used words at least more than 3000, a single byte can not hold so much information, so Huaxia uses double bytes to display Chinese computers, Peking University is the developer.

This brings a problem, the single-byte double-byte standard is different, the two are not compatible, and the English software will have half a Chinese character when processing Chinese characters.

For a long time, it was an editing program written according to his habits in the DOS era.,Naturally, it's processed into a double byte.,I didn't expect to be so fancied.,It's really a joy to fly.。

Excuse me, is it okay to have real people?
