The two girls have always been interested in the things produced by the science and technology park themselves, and even the gas turbines that they can't understand at all can listen to Li Yuanling's explanations with peace of mind, and they are naturally very curious about pagers, which were still very fashionable communication products in the late eighties.

The two sat on both sides of Liang Yuansha's handrails, urging Liang Yuan to open the box quickly.

Different from the more empty packaging of electronic products that was common in later generations, the box was stuffed to the brim, and Liang Yuan took a lot of effort to open the lid, and a manual with a finger thickness slightly smaller than the box came into view.

Taking away the manual, there was a boxy solid black pager underneath, a paging protective case with a clip, and a green circuit board full of components next to the two finished products, Liang glanced at the circuit board that looked like it should be a pager.

"Gee, it looks a lot smaller than it did in winter. ”

"Xiaoyuan, this pager screen is so wide. ”

"Yes, yes, this screen is not the same as the color we will see during the New Year."

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

The large two-finger-wide screen occupies more than half of the entire pager's surface area, and on the left side of the screen is printed the slightly elongated variant of the Port-based collector Möbius ring logo and h-k-I-netbsp; At the bottom of the right side of the screen are two independent soft rubber buttons with a diagonal setting of 45 degrees, one for turning up and down the pages of the screen information, and one for entering and exiting submenus.

On the left side of the pager façade, the power indicator and keychain are designed as one. Underneath the indicator is a screen light switch, while the paging power button is designed to the right façade.

Although the pagers opened by the communication center also use the Tn-LCD screen, which is relatively popular at present. However, when choosing the LCD screen, the Science and Technology Park chose a special polarizer, which made the dark green background of the screen gray and white, and the contrast ratio was much higher than that of ordinary LCD screens.

This is also the reason why the pager screens of the two girls in the Science and Technology Park look a little shallow.

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

For ordinary microcontroller enthusiasts like Liang Yuan, although they can't figure out the coding in paging technology, RF stabilization and other difficult technical principles, but look at the component structure. It's still relatively clear which chip is responsible for what.

On the light green electronic substrate, three processors produced by Gangji Jidian are square-shaped and inlaid in the center of the circuit board.

In addition to the three processors, there is a rectangular Rom chip embedded on the left side of the circuit board, on the right side of which is a small motor responsible for generating vibrations, and a gray-green LCD screen connected to the upper part of the electronic substrate through a large series of cables.

Directly above the circuit board, two endpoints protrude from a rectangular frame made of a bent aluminum wire, which looks like a paging RF receiving antenna.

Liang Yuan looked at the light green circuit board in his hand with some intoxication, and no one knew it for the time being. The great value of this board in their own hands.

For example, the RF substrate for paging has the function of receiving and processing wireless signals, and if it is further studied, the function of sending RF signals will also be added, and it will become the core technology used in digital mobile phones in a few years - baseband chips.

In addition to the outsourcing of caches, vibration motors, Tn screens and general electronic components, the core technologies of Hanxian paging such as RF substrates, communication processors, and Chinese character codecs have been continuously developed by Gangji Electric in nearly two years6.

The core of the communication processor designed by the communication center adopts the mIps architecture. However, the peripheral circuitry has long since changed beyond recognition.

However, the operating frequency of the three chips, which are simply named F2 communication processors by the communication center, is much lower than that of the c2 processor of the Hong Kong-based power collector, with a maximum of only 15mkZ.

"Xiaoyuan. What are these chips for?" Ning Wanjia asked curiously, pointing to the three F2 processors on the circuit board.

"This piece is responsible for driving the LCD screen display, and this piece is responsible for controlling the output of Chinese characters and letters. This piece is to control the normal operation of the entire RF circuit, such as vibration, power on/off, prompt sound, and so on. Liang Yuan pointed to the three chips and told Ning Wanjia about the relevant functions one by one.

"It looks so complicated, didn't Xiao Yuan say that the processor can do a lot of things, why not use a processor?" Listening to Liang Yuan tell Ning Wanjia about the structure of paging, Ning Wanfei handed the prototype in her hand to Xiong Weixin, and then rarely joined in the fun.

"Lack of performance, English, Latin and other alphabetic word processing, counting the upper and lower case generally only need about 5o fixed symbols, even if the commonly used Chinese characters are simplified, they also need to process more than 2ooo characters, if you add the trouble of display, the difficulty of Chinese characters in computer processing is at least 20 times that of alphabetic 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 a lot of jokes that he had never heard of in later generations, and as the world of flowers outside the country completely broke the backbone of many people, some reverse racists openly declared that Chinese civilization was the most backward civilization on the planet.

For example, it means that advanced computers are very difficult to process Chinese characters, and even need a special Hanka connection to use this device that is destined to rule the future, which means that Chinese civilization is incompatible with the mainstream of mankind.

Similar remarks are very popular among the groups who worship "River Death", for example, among the people who love walking, there are always heartbroken children of heaven who are excited to interpret this kind of joke.

Wang Mengmeng, Liang Yuan's tablemate in the juvenile class, made a female pen pal who studied in the juvenile class of the University of Science and Technology, and the two discussed the issue of Chinese characters and computers in their correspondence.

In someone's words, with the flying of semiconductor technology. With the doubling of processor power, the so-called Chinese characters will be nearly as difficult to process on a computer as possible for a maximum of five years. In the distant future, representing the ultimate form of the computer technology exhibition, artificial intelligence, Chinese characters have incomparable advantages.

Regardless of the technical approach of artificial intelligence, the ability to independently understand the whole world should be a sign of the success of artificial intelligence, relatively speaking, 2ooo Chinese characters can basically accurately describe more than 7o% of the content of the whole world, and what can the corresponding 2,000-letter words do?

Chinese is an extremely refined and grand language, similar to Dao Zhi Simple. Corresponding to the Western language, it is a precise and cumbersome language, in which everything in the world has a special title and noun expression record, and the Western language has a slight advantage in the current stage of human civilization.

The core of the problem is that with the progress of civilization and the development of knowledge, the language and writing used to carry knowledge are destined to carry more and more content, when information tends to infinity. Should the vocabulary of the Western language also be developed into infinity?

Just like a picture, when the lines are complicated to the extreme, it means that the whole drawing board is pitch black, and when the information tends to infinity, the collapse of Western literature is obvious, which can be fully confirmed from the popular eschatological theory of Western civilization, but China has never had any bullshit eschatology, and Chinese civilization has always believed that the future of mankind is to become immortals and attain happiness, and ...... is extremely happy.

Although the future is uncertain. But the logic in Liang Yuan's theory is indeed real, and for a time this extremely sci-fi topic has become a hot topic of correspondence between the two junior classes of Tokyo University and University of Science and Technology, from technology to philosophy, from science to human nature, and as a result, some people in the junior class still mention it from time to time.

Of course. The two girls admired Liang Yuan's ability to death, and after someone pretended to be a god, she received two fragrant kisses.

"It's no wonder that the pagers commonly used by Hong Kong people look so small. Ning Wanfei said thoughtfully.

"If it's just in English, or if you use pinyin to express Chinese characters. This type of pager only needs an F2 chip to drive the whole system normally, and the memory on the right for storing Chinese character codes is also not needed, and it can be done exactly like the popular small computers in Hong Kong. Liang Yuan pointed to the square F2 communication chip and the rectangular Rom memory and said.

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

"If only one chip is used to control the system, the main frequency of the communication processor must reach at least 9omhZ, and the first-level cache must reach at least 256kB, which means that the performance of the chip will be increased by three to four times. ”

A month ago, the American mIps company, which understands the mIps architecture, has just laid out the first upgraded version of its flagship processor R3ooo, which uses 1 micron advanced process technology to manufacture the highest frequency of the R3oooa processor, from R3ooo's 3omhZ to 4omhZ, but it is still not close to 9omhZ.

"It's a big screen. Wilson Xiong was full of praise for the large 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 taken aback by Xiong Weixin's keen military sense, and being able to provide information and read maps had become a digital tactical terminal in the hands of the "Wang Shi".

Pointing to the two-finger-wide large LCD screen of the pager in Xiong Weixin's hand, Liang Yuan said with a smile: "Because of the use of three processors, there is really no way to reduce the volume, in order to look coordinated, Lao Su and they decided to turn the screen into two rows, otherwise they would not be so kind to choose the large screen." ”

"However, Uncle Wilson said that the information can see the map, it seems that there must be satellite or ground base station support, technically speaking, the relevant technology will mature one by one in about ten to fifteen years, but the cost and difficulty are not small, I estimate that the ground support system, Uncle Wilson's professional may not be able to see, the satellite system support system is afraid that the country will take the lead to achieve it. ”

Xiong Weixin laughed, and he was deeply convinced of Liang Yuan's statement.

While the four of them were chatting, Qi Lianshan and Liang Haiping returned to the hotel one after another, and after complaining about the traffic 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 single-chip microcomputers, can also be called professionals, combined with manuals, circuit boards, and commodity prototypes, from the market to technology, from the industry to the future, Liang Yuan said this new product of Gangji Collector very thoroughly, and everyone nodded frequently.

"This is an epoch-making breakthrough, the world's first Chinese character pager was actually left in the corner for three or four days, even in Hong Kong, it is an explosive news to release it casually. Qi Lianshan looked at Liang Yuan helplessly.

"Uh... , I've been busy with things in Jardine these days, and Lao Su called me on the day I received the mail, but I turned around and received a call from Zhou Yuanhang, and then I forgot about it. Liang Yuan said with some embarrassment.

Because of the extremely advanced future of the semiconductor industry, the pager is an instant messenger in Liang Yuan's eyes, and he really doesn't feel any epoch-making feeling, in someone's opinion, mp3 players, smartphones, touch tablets and other things can be associated with the great word epoch-making.

"Xiaoyuan has been fooling Liu Changhe for nearly two years, and now that the finished product is finally out, the waiting time for the sample is still quite worthwhile, Xiaoyuan said, how do you plan to cooperate with the railway system?" Liang Haiping asked with a smile.

ps: Uh, I'm busy during the holidays, and even the network is going to be cut off, so I'm going to update it, thank you for the book friends ^_^ who appreciate moon cakes and osmanthus wine
