Chapter 87 Inventing Wenquxing

In 1997, Wenquxing PC22 was launched. It sold for 330 yuan and had a built-in game called "Snake".

There is no doubt that the main function of Chinese character dot matrix Wenquxing is games.

It’s just that the vast majority of parents don’t believe this when buying!

I always thought that with Wenquxing, I could do well in English...

Later, some people bought more advanced ones and could play "Hero Forum"!

Li Sanbiao cannot comment on such wishful thinking.

If it can only play games, it will definitely be called a dog, so Li Sanbiao still has to give it a dictionary.

He asked A Yuan to bring him a dictionary. What A Yuan brought was the "New English-Chinese Dictionary" from Modou Translation Publishing House.

Until 2000, there were no foreign dictionaries such as Oxford, Longman and Cambridge. They were all compiled by the Chinese themselves.

The most popular English-Chinese dictionary is none other than the New English-Chinese Dictionary!

There was an English craze in 1981, which set off a craze for everyone to learn English!

Although the price is very high, the book is hard to find!

In fact, foreign dictionaries are not suitable for students from the Dragon Kingdom, because foreign dictionaries do not distinguish between transitive and intransitive verbs, that is, Vt and Vi.

However, Longguo’s own dictionary is differentiated, and the exam is specifically directed to this top,

Therefore, the dictionaries compiled by Long Guo in the 1980s were more suitable for the examination requirements, but it was a pity that they later became foreign dictionaries that dominated the world.

Li Sanbiao made up his mind to create a tailor-made dictionary for many students, and the best foundation is this one!

Li Sanbiao flipped through the dictionary and realized that the book was so thick. Fortunately, the third uncle could directly import the contents of the electronic dictionary into the storage ROM.

He took out a piece of read-only memory and silently said to the third uncle to start work, but he got a message that the writing failed!

Li Sanbiao suddenly discovered that there seems to be no universal Chinese character library in the current computer system! Therefore, there is no way to recognize and display Chinese!

But Li Sanbiao is very confident and thinks that there is no need to ask Academician Wang to transfer this technology because he has the third master of supercomputing!

Aren’t Chinese characters just a dot matrix?

Bitmap fonts are also called bitmap fonts, in which each glyph is represented by a set of two-dimensional pixel information. It divides each English letter into 8x16 points, and Chinese characters are divided into 16x16 or 24x24 points.

Later, computer performance improved and it became 96X96 points.

This text display method was commonly used in earlier computer systems (such as the DOS operating system without a graphical interface), but it is easily distorted when scaling.

A byte has 8 bits, and one bit represents a point, so a byte can only represent 8 points.

Because there are 26 letters in English, 8x16 dots, and 8 bits are exactly one byte, so one letter requires 16 bytes. 26 letters are 26X16=416 bytes. Even if uppercase letters and numbers are added, a total of 1K memory is required.

!

When a Chinese character needs to be displayed in a 16x16 dot matrix, a Chinese character with a 16x16 dot matrix will occupy 2x16=32 bytes.

Then the commonly used 3755 first-level Chinese characters require a total of 3755x32= bytes. And 1KB=1024 bytes, so the first-level Chinese character library requires 117KB of storage space. Taking the integer power of 2, it is 128KB.

Therefore, when the fonts are the same, there are as many Chinese character bitmap fonts as there are font sizes.

In other words, Chinese characters are essentially a graphics library on the computer.

For Li Sanbiao's Wenquxing, only one Song style, with two fonts, large and small, is enough.

Therefore, he feels that there is no need for powerful hardware specifically for processing Chinese characters.

Wenquxing requires at least two font sizes, Song-style and small, which is 256K!

Well, plus a few games, 1 megabyte of memory will be enough.

"Ayuan, go find a memory stick with 1 megabyte of memory!"

A Yuan was shocked this time:

"Brother A Biao, 1 MB of memory? Are you kidding me? I heard that the largest memory is only 256K, and it's not on the market yet!"

Li Sanbiao patted his head and saw the perspective of a time traveler again!

In 1978, the largest memory was only 64K!

For 8086 microcomputers, the commonly used memories are 8K and 16K!

As for Apple II computers, the early memory was only 4K!

Existing computers are not enough to accommodate the 128K Chinese character library!

It is now 1981, and the maximum memory that will be released at this time is only 256K!

The 128K that can be seen on the market is a super luxurious configuration! If you read a font library, you can't do anything!

Li Sanbiao was speechless. It’s not easy to be a literary star. Just a Chinese character library destroyed the world’s top computers! No wonder A Yuan is in a dilemma!

Li Sanbiao remembered that to solve the problem of inputting Chinese characters, in 1974, the Fourth Ministry of Machinery took the lead in carrying out the Chinese character informatization project code-named Project 748.

This dot matrix scheme was invented by Academician Wang Xuan.

Later, he invented the "contour parameter" technology to store Chinese characters, which compressed Chinese character information 500-1000 times and solved the problem of insufficient storage space for Chinese character information.

The news bulletin just broadcasted that the Huaguang 1 laser imagesetter has just been built, and an original chip has been invented through a combination of software and hardware.

The font restoration speed reaches 710 words per second, realizing high-precision computer phototypesetting of Chinese characters.

Li Sanbiao lamented that although Academician Wang greatly compressed the size of the lattice, ordinary memory can also run Chinese character software.

But the efficiency of 710 words per second is really impressive!

But this is a laser imagesetter supported by the whole country, and it’s huge!

If we switch to a handheld console like Wenquxing, even if we follow Academician Wang’s method of compression,

We have to face the difficulty of insufficient chip computing power during decompression!

Now Li Sanbiao hesitated, is it so difficult to be an inconspicuous literary star?

With current technology, is it really impossible for Chinese characters to appear on handheld devices?

A Yuan took out a handkerchief and wiped Li Sanbiao's sweat very thoughtfully.

Li Sanbiao suddenly had an idea. At worst, he could connect several chips in series to form a 4-core chip, which would greatly increase the computing speed!

As soon as he said it, Li Sanbiao immediately asked the third uncle to start calculations, thinking that six computing chips would be connected in series and improved, and then the Chinese character lattice would be changed from 16X16 to 4X4 according to the size of Wenquxing, which can roughly meet the computing requirements.

Today's Wenquxing is not necessarily so small. I asked the third uncle to slightly increase the size, and after a while of revisions, I finally drew a perfect circuit diagram, which is as thick as 50 A1 drawings!

Li Sanbiao was very satisfied with this and said: "A Yuan, Wenquxing has been designed. The chief engineer should be satisfied!"

A Yuan looked at the design drawings and felt waves in his heart!

Relying on this blueprint, I will definitely be able to return to the family and become the apple of my eye!

She admired Li Sanbiao infinitely, and although she wanted to repay him, she had no way of opening her mouth.

Li Sanbiao spent a day drawing pictures, and his back ached and he felt very tired.

Mao Xiaotong brought him a bowl of ginseng Qi-boosting soup and helped him to rest in the back.

Of course Li Sanbiao is really taking a rest, the female secretary is just doing what she should do,
Chapter completed!
