In the 80286 era, some graphics-related design software began to appear on personal computers, and programmers at that time also began to write some small games for their leisure time, or port some games on game consoles to the PC. Pen, fun, and www.biquge.info

At this time, there is a four-color adapter that can recognize three-dimensional colors and black and white.

The display of this adapter was very mediocre, but at the time it was a big step forward.

Since this is the first color display card, it is called CGA.

In the CGA era, the requirements for graphics cards have increased significantly, but CGA graphics cards are still integrated into the motherboard and implemented in a single-chip way.

It wasn't until 1987 that IBM introduced the PS/2 personal computer.

The sales of this computer are very popular, but the VGA video transmission standard used on the PS/2 has been widely used in the field of color displays because of its advantages of high resolution, fast display rate, and rich colors.

It is from this era that the graphics card began to become independent and become a graphics card in the true sense, rather than an unknown chip.

Yang Weining naturally will not ask Jiangnan to come up with a graphics card that meets the VGA standard, because although the VGA standard can be realistic16 colors, it requires the graphics card to have at least 512KB of video memory, which is not possible with current technology, even if the laboratory can make it, the cost is too high to promote.

What Yang Weining wants is just a four-color display card.

Listening to Yang Weining's idea of a four-color display adapter, Gu Pei thought for a while and said: "This is a good way, but this matter has already involved the cooperation between the two research units, and I can't make a decision alone, so let's go to Lu Suo, and he will come forward and say to Jiangnan." ”

Yang Weining nodded and smiled: "That's great, otherwise if I go rashly alone, Lu might think that I can't get CAD software, and use this excuse to prevaricate him." ”

Gu Pei smiled, if he hadn't seen Yang Weining's programming level with his own eyes, he might have such doubts in his heart.

The two of them said that, regardless of whether it was still working time, they got up and went directly to the administrative building to find Lu Wenjun.

As soon as they arrived at the door of Lu Wenjun's office, Yang Weining and Gu Pei were stopped by a young girl in her twenties.

"Director Gu, why are you here?"

Gu Pei obviously knew this girl, and said, "Secretary Liu, Director Lu is here, you go in and help me inform me, just say that I have something important to discuss with him." ”

The girl showed a look of embarrassment on her face, and said, "Director Gu, Director Lu is meeting with an important guest, and he specially instructed me before, saying that no one will go in to disturb him, you should not wait any longer." ”

Although Secretary Liu said it to Gu Pei, his eyes couldn't help but glance at Yang Weining, secretly guessing the identity of this handsome young man.

Thanks to the excellent genes of the cheap father, Yang Weining's appearance conditions are very good, coupled with the temperament that is very different from the Chinese people of this era, it can naturally attract the attention of many people of the opposite sex.

Gu Pei said: "Secretary Liu, we can wait here for a while, but you better go in and inform us, our matter is more urgent." ”

"This ......"

Secretary Liu's face showed embarrassment.

At this moment, the office door suddenly opened, and Lu Wenjun and an old lady who looked to be in her sixties and wore glasses walked out of it.

Although the old lady is old, she has excellent spirits and fair skin, and it can be seen from her facial features that she must have been a rare beauty when she was young.

Seeing this old lady, Gu Pei's face changed, and he hurriedly stepped forward and said, "Professor Xia, why did you come to Rongcheng?"

"Who are you?"

The old lady lifted the glasses on her face and wondered.

"I'm Xiao Gu, Gu Pei, do you remember me? Seventeen years ago, at Huaqing University, I also participated in the computer project led by you!"

"Are you Gu Pei?" the old lady obviously recognized Gu Pei and said in surprise: "Why did you come to work in the 611 Institute? I remember that you were not assigned to the University of Science and Technology of China at that time?"

Gu Pei sighed: "It's hard to say, Professor Xia, why did you come to the 611 Institute today?"

Professor Xia said with a smile: "Lao Lu and I are college classmates, and this time I came to Rongcheng on a business trip, and I came to meet my old classmates by the way." ”

Lu Wenjun didn't expect Gu Pei to know this old lady, and said with a smile: "This is really a coincidence, I didn't expect that Lao Gu you also knew Professor Xia." Oh, by the way, let me introduce you, Lao Xia, this is the Yang Weining I told you, and now he is helping us develop CAD software. Wei Ning, this is Professor Xia Peisu, a well-known computer expert in China. ”

In fact, there was no need for Lu Wenjun to introduce him, when Gu Pei said the three words Professor Xia, Yang Weining recognized who this old lady was.

Xia Peisu, academician of the Chinese Academy of Sciences, the founder of China's computer industry, known as the mother of China's electronic computers, is an extremely rare female computer expert in this era.

In 1958, she was responsible for the design and development of the general-purpose electronic digital computer 107, which was China's first self-developed general-purpose electronic digital computer, which proved with facts and actions that the Chinese had the ability and ambition to design and develop their own computers.

She proposed the principle of the maximum time difference pipeline that greatly increases the computing speed of the computer, which greatly shortens the clock cycle of the pipeline computer.

In addition, she effectively solves the waveform distortion problem that occurs during high-speed signal transmission in mainframe computers.

The research results have been adopted or referred to by many domestic units that develop large-scale high-speed computers. Based on this, she also formulated specific engineering design specifications for a number of high-performance computers that she was responsible for designing and developing, and achieved good signal transmission results.

She was responsible for the successful development of the high-speed array processor 150-AP, the computing speed of the 150 computer is 1 million times/second, and the computing speed of the 150-AP has reached 14 million times/second, which is higher than the computing speed of similar products embargoed by the United States to China at that time, which has received great attention in the world and made a significant contribution to China's petroleum exploration.

She presided over functional distributed computer systems and led the team to successfully develop the GF10 series of computers, which later became the focus of research in the Institute of Computing Technology for a period of time.

In addition, she also founded the Journal of Computer Science, which is the most influential in the field of computer science in China, and the Journal of Computer Science and Technology, which is distributed abroad, and presided over the compilation of the English-Chinese Computer Dictionary.
