The two girls have always been concerned about the things they produce on the Science and Technology Park. They can even listen to Li Yuanling's explanation with peace of mind when they don't understand them. They are naturally curious about pagers, which were very fashionable in the late 1980s.

The two sat on both sides of Liang Yuan's handrails, urging Liang Yuan to open the box as soon as possible.

Unlike the relatively empty electronic products commonly seen in later generations, the box was stuffed with a lot of effort. Liang Yuan took a lot of effort to open the lid. A manual with a foot and a finger thicker than the box first came into view.

Taking the instruction manual, there was a square pure black pager and a pager protective cover with clips. A green circuit board full of components was placed next to the two finished products. Liang Yuan glanced at the circuit board that looked like it was the pager.

"Oh, it looks much smaller than winter."

"Xiaoyuan, this paging screen is so wide."

"Yes, yes, this screen is different from the colors we saw during the Chinese New Year."

“It seems to be much lighter than the display screens of electronic watches and calculators.”

A large two-finger-wide screen occupies more than half of the entire pager surface area. On the left side of the screen, the slightly elongated variant of the Hong Kong-based current collector is printed with the English abbreviation of the H-K-I-C.

Below the right side of the screen are two independent soft rubber buttons with an angle of 45 degrees obliquely set, one for up and down pages of screen information, and the other for entering and exiting submenu.

On the left side of the pager facade, the power indicator light and keychain are designed to be integrated. Below the indicator light is the screen light switch, and the pager power key is designed to the right facade.

Although the pager developed by the Communication Center also uses the current popular TN-LCD screen. However, when choosing an LCD screen, the Science and Technology Park chose a special polarizer, which makes the dark green background of the screen look gray and white, and the contrast is much higher than that of ordinary LCD screens.

This is also the reason why the two girls found that the pager screen of the Science and Technology Park looked a bit shallow.

Liang Yuan took out the instruction manual and threw it to Xiong Weixin opposite him, handed the pager to the two extremely curious girls, and then picked up the circuit board and looked at it carefully.

For ordinary microcontroller enthusiasts like Liang Yuan, although they cannot understand the high-difficulty technical principles such as coding in paging technology and stable radio frequency reception and transmission, it is still clear which chip is responsible for what it is.

On the light green electronic substrate, the three Hong Kong Basic Core Co., Ltd.'s own processors are embedded in the middle of the circuit board in a square shape.

In addition to these three processors, there is also a rectangular ROM chip embedded on the left side of the circuit board. On the right side of the circuit board is a small motor responsible for vibration. The gray-green LCD screen is connected to the upper part of the electronic substrate through a large series of wires.

A rectangular frame bent from an aluminum wire extends at the two end points directly above the circuit substrate, which looks like a paged RF reception antenna.

Liang Yuan looked at the light green circuit board in his hand intoxicatedly. No one knew the great value of the board in his hand.

For example, the radio frequency substrate for paging already has the function of receiving and processing wireless signals. If further research and development is further developed, the function of sending radio frequency signals will be added, which will become the core technology used in digital mobile phones in a few years - baseband chips.

In addition to the purchase of cache, vibration motors, TN screens and general electronic components, core technologies such as radio frequency substrates, communication processors, Chinese character encoding and codecs, etc., have been developed by Hong Kong Base Collective in nearly two years.

Although the core designed by the communication center for the communication processor uses a MIPS architecture, the peripheral circuit has long been changed beyond recognition.

However, the chip operating frequency of the three blocks, which are simply named F2 communication processors by the communication center, is much lower than that of the C2 processors of the Hong Kong-based power collector, with a maximum of only 15MKZ. It is precisely because of the insufficient chip performance that three F2 communication processors have to be installed on the paged RF substrate.

"Xiaoyuan. What do these chips do?" Ning Wanjia asked curiously at the three F2 processors on the circuit board.

"This is responsible for driving the LCD screen display, this is used to control the Chinese characters and letter decoding output. This is used to control the normal operation of the entire RF circuit, such as vibration, power switch, sound prompt, etc.." Liang Yuan pointed to the three chips and talked about the related functions with Ning Wanjia one by one.

"It looks so complicated. Didn't Xiaoyuan say that the processor can do a lot of things? Why don't you use a processor?" Hearing Liang Yuan telling Ning Wanjia about the paging structure, Ning Wanfei handed the prototype in her hand to Xiong Weixin, and then joined in the fun with her rare.

"The performance is insufficient. In English, Latin and other alphabetical characters, generally speaking, only about 50 fixed symbols are required to include upper and lower case. Even after the commonly used Chinese characters are simplified, they still need to process more than 2,000 characters. If the display trouble is added, the difficulty of processing Chinese characters in computers is at least twenty times that of alphabetical characters." Liang Yuan said with some emotion.

In this life, as Liang Yuan came into contact with the computer industry very early, he had heard many jokes that he had never heard in later generations. As the country opened its doors and the flower world outside completely defeated many people's backbone, some reverse racists openly claimed that Chinese civilization is the most backward civilization on this planet.

For example, it means that advanced computers are very difficult to process Chinese characters, and even require dedicated Han card connections to use such equipment that is destined to dominate the future, which means that Chinese civilization is incompatible with the mainstream of human beings.

Similar remarks are very popular among the groups who worship "Heshang". For example, among the people who love to take a walk, the heartbroken prides of heaven are always emotionally interpreting such jokes.

Liang Yuan’s deskmate Wang Mengmeng, who was in the junior class, had a female pen-friend who was studying in the junior class of the University of Science and Technology. The two had discussed the issues of Chinese characters and computers in their correspondence. After Liang Yuan learned about it, Liang Yuan criticized this view.

In someone's words, with the rapid development of semiconductor technology and the doubled processor capability, the difficulty of processing so-called Chinese characters on computers will become almost non-existent in the distant future. In the distant future, in artificial intelligence, which represents the ultimate form of computer technology development, Chinese characters have unparalleled advantages.

No matter what technical approach is artificial intelligence achieved, being able to independently understand the entire world should be a sign of the success of artificial intelligence. Relatively speaking, 2,000 Chinese characters can basically accurately describe more than 70% of the content of the entire world. What can the corresponding 2,000 alphabetical vocabulary do?

Chinese is an extremely refined and grand language, similar to the simplest way. In this way, Western language is an accurate and complicated language. In Western language, it wishes that everything in the world has a unique name and noun expression record. From the current stage of human civilization, Western language has a slight advantage.

The core of the problem is that with the progress of civilization, the language and text used to carry knowledge are destined to carry more and more content. When information tends to be infinity, will the vocabulary of Western languages ​​also develop into infinity?

It is like a picture. When the lines are complex to the extreme, it means that the entire drawing board is pitch black. When information tends to be infinity, the collapse of Western languages ​​is obvious. This can be fully confirmed by the popular apocalyptic theory of Western civilization. However, China has never had any bullshit apocalyptic theory. Chinese civilization has always believed that the future of mankind is to become an immortal and achieve the Tao and be extremely happy...

Although the future is untestable, the logic in Liang Yuan's theory is indeed real. For a time, this extremely science fiction topic became a hot topic for letter exchanges between two junior classes of the University of Science and Technology of Dongda University and the University of Science and Technology, from technology to philosophy, from science to human nature. As a result, people still mention it from time to time in the junior class.

Of course, the two girls admire Liang Yuan's nonsense ability so much. After pretending to be a charlatan, they really gained a sweet kiss.

"No wonder the pager commonly used by Hong Kong people looks so small." Ning Wanfei said thoughtfully.

"If you only display English or express Chinese characters in pinyin, this type of pager only needs a F2 chip to drive the entire system normally. The memory used to store Chinese character encoding on the right is no longer needed. It can be made like the popular small machine in Hong Kong." Liang Yuan said, pointing to the square F2 communication chip and rectangular ROM storage.

"Xiaoyuan, how long will it take to make Chinese character paging as small as commonly used in English paging in Hong Kong?" Ning Wanjia asked.

"If only one chip is used to control it, the communication processor's main frequency must reach at least 90MHZ and the first-level cache must reach at least 256KB, which means that the chip's performance must be improved by three to four times. Even in the United States, the most developed electronics industry, there are no commercial processors with such high main frequency now."

A month ago, the American MIPS company, which invented the MIPS architecture, just released the first upgraded version of its flagship processor R3000. The highest main frequency of the R3000A processor made using 1 micron advanced process technology has been increased from 30MHZ of R3000 to 40MHZ, but it is still a short distance from 90MHZ.

"This big screen is really good." Xiong Weixin praised the big screen of the pager in his hand.

"Xiaoyuan, do you think this thing can send information or maps to each other in the future?" Xiong Weixin asked casually.

Liang Yuan was shocked by Xiong Weixin's keen military feeling. Being able to send messages and view maps has become a digital tactical terminal for the "King Army" to call styles.

Pointing at the large LCD screen with two fingers wide on Xiong Weixin's pager, Liang Yuan smiled and said, "Because it is used for three processors, there is no way to reduce the size. In order to look harmonious, Lao Su and the others decided to turn the screen into two lines, otherwise they would not be so kind to choose a large screen."

"However, Uncle Weixin said that he could send messages and see maps, and it seemed that he would need to have satellite or ground base station support. Technically speaking, the relevant technologies will mature one by one in about ten to fifteen years, but the cost and difficulty are not small. I guess Uncle Weixin's professionalism may not be able to like it. The system supported by satellite systems is probably led by the state to be able to be realized."

Xiong Weixin laughed and agreed with Liang Yuan’s statement.

While the four of them chatted, Qilianshan and Liang Haiping returned to the hotel one after another. After complaining about the transportation in Hong Kong, both of them were very interested in the pager sample that Liang Yuan had just taken out.

Among the few people in the room, Liang Yuan, who loves microcontrollers, can also be called a professional. Combined with the instructions, circuit boards, commodity prototypes, from the market to technology, from the industry to the future, Liang Yuan explained the new product of Hong Kong and Electric Power Collection very thoroughly, making everyone nodded frequently.

"This is an epoch-making breakthrough. The world's first Chinese character pager was thrown into the corner by the eldest son for three or four days. Even if this news is in Hong Kong, it will be an explosive big news if it is released casually." Qilianshan looked at Liang Yuan helplessly.

"Uh..., I have been busy with Yihe's affairs these days. On the day I received the receipt, Old Soda called me to remind me, but turned around and received another call from Zhou Yuanhang, and I forgot it." Liang Yuan said embarrassedly.

Since it comes from the extremely developed future of the semiconductor industry, the instant messaging tool of pagers is just an antique in Liang Yuan's eyes, and he really didn't find any epoch-making feeling. In someone's opinion, MP3 players, smartphones, touch tablets and other things can be linked to the great vocabulary of epoch-making.

"Xiaoyuan has been fooling Liu Changhe for nearly two years, and the finished product has finally been calculated. It seems that the waiting time for the sample is quite worth it. Xiaoyuan tells me, how do you plan to cooperate with the railway system?" Liang Haiping asked with a smile.

PS: Well, I was so busy during the holidays that even the Internet was about to be cut off. I'm going to be updated. Thank you to the book friends who enjoyed mooncakes and osmanthus wine^_^
