Zhao Ting has been pregnant for more than 6 months, and her body has begun to have difficulty moving. Since 5 months, Li Guocheng has been picking up and dropping off every day. With Li Guocheng's strong body control, the bike is very stable. Zhao Ting also slowly got used to Li Guocheng's care.

Since the ninjas of Xiaori were wiped out, the capital has strengthened the management of foreigners, especially after the frequency of patrols in Jing'er Hutong was strengthened, and it has been calm for more than 3 months.

It was another sunny summer morning, Li Guocheng was writing and painting at his workstation, and Wu Liankui walked in happily.

"Lao Li, look, this is a large pine nut, for Zhao Ting", said and threw a large bag of pine nuts on the workbench, which was more than 2 catties.

"Oh, this is just coming back from Harbin, have you been annoyed with the Northeast pig killing dishes", Li Guocheng said narrowly.

"It's nothing to mention this stubble, before you went, you told me how good the Northeast pig killing dish is, and said that it is much more authentic than what you Lao Li made. You don't know, the master of Hagong Machine Tool Factory is a second knife, a good pork belly, it only tastes like sauerkraut, and the sauerkraut is a little bitter."

Speaking of this trip, Wu Liankui was afraid for a while, not only did he not eat well, but he was almost drunk to death, "The Northeast people are too powerful, and every thief can say, if you don't drink, it seems that you have made a big mistake."

"Hahaha", Li Guocheng laughed heartily.

"No kidding, this is a task issued by the ministry, and the materials will be sent over to the logistics department in a while," Wu Liankui said, handing over a file bag.

"Yes, Lao Li, the document said that this is a state guest gift, Director Li is very happy, so let you have time to make a few more. How about it, make a few for my brother too", Wu Liankui flattered himself.

"Okay, as long as the materials are sufficient, make a few more, how to divide it, I don't care, hehe."

In front of Wu Liankui, he opened the file bag, and inside was a hand-drawn drawing, a domineering and mighty dragon soaring above the clouds, as if it had broken out of paper.

"It's so beautiful! It's so exciting! Wu Liankui praised again and again, his eyes full of obsession.

Dragon, Li Guocheng has carved a lot, and there are more vivid than this, but there is no ingenious idea of this painting, with simple lines, it depicts the momentum of the dragon soaring nine days, and the dragon body looms in the clouds and mist, which is more agile and extraordinary.

Li Guocheng reproduced the whole painting in his mind, slowly pondering the charm of the author's painting and the artistic conception of the conception, and slowly felt that he had grasped something, but it seemed that there was nothing.

"Lao Li, something is coming", Wu Liankui's voice interrupted Li Guocheng's understanding.

Li Guocheng did not complain, how could he learn the skills of a painter in a short period of time after decades of skill, and he was not interested in this, and he no longer had the energy to study painting.

As a master carver, painting and composing scenes is not a specialty, but reproduction, that is, holding a handle.

The logistics sent are all high-quality small leaf red sandalwood specially prepared by the ministry. Li Guocheng picked up a piece, looked at it carefully for a while, then took out a carving knife and carved it with a brush.

Throughout the day, Li Guocheng completed the engraving of a total of 6 radio shells, and this time the task was 50 units. With the mastery of graphics, the speed of engraving is getting faster and faster.

Sure enough, in just one week, Li Guocheng completed the engraving of 60 radio shells. handed it over to Yan Jiefang and asked him to help spray protective paint.

Now the rolling mill is fully producing Shuguang brand radios, the cost is only 25 yuan, the ex-factory price is 45 yuan, and the sales price is 85.

After the factory leaders discussed, they temporarily requisitioned the auditorium, transferred young people from various workshops, and began the assembly work in three shifts.

Now Wang Gong is a headache, and the five factory representatives who have obtained the index are staying in the machine tool laboratory of the rolling mill, waiting for the manufacture of the chip production line.

Through a struggle, under the supervision of Li Huaide, the order of raising the line was determined by drawing lots, but they still did not leave, and the five representatives were still in the machine tool laboratory

They are also anxious, seeing that the sales of Shuguang brand radios are booming, and the leaders of the five factories are also anxious.

After receiving 60 painted shells, Li Guocheng carefully checked that there were no problems with all the shells, and after assembling them himself to ensure that each radio was free of any flaws, he handed over the 60 radios to Wu Liankui, and it didn't matter how he distributed them.

After the short-term task was completed, Li Guocheng began the design of DRAM memory chips again.

This time it went very smoothly, nothing happened again, and in September, the design of the DRAM memory chip was completed. A set of masks is designed with 12 pieces.

Coincidentally, the commissioning of Yan Jiefang's lithography machine came to an end, and Li Guocheng personally participated in the final commissioning. A week later, all the preparations were completed.

After communicating with the dust-free workshop, everyone in the semiconductor laboratory participated in the preparation of the first real chip with excitement, and it was the simultaneous manufacture of CPU and DRAM.

In order to achieve an accuracy of 1 micron, the wafer is divided into multiple photolithography and etching, which requires very high operations, in order to ensure success, Li Guocheng is personally responsible for the lithography process, and the subsequent process etching, doping, segmentation, packaging and testing are handed over to others in the laboratory to complete, and Li Guocheng is on the side to guide.

In order to complete chip manufacturing, a lot of tooling and fixtures are designed for it, in order to meet the needs of industrial mass manufacturing. Although the chip is complex, with the assistance of tooling and fixtures, everyone has responded, and the process operation they are responsible for is simple and accurate.

Everyone returned to the semiconductor laboratory, looking at the CPU and DRAM on the tray, excited, they have been listening to Li Guocheng explain computer technology recently, they all know the importance of these two chips, and they all want to see the birth of computer technology beyond the current all countries.

They are both witnesses and participants, and in the most recent stage, although Li Guocheng was in charge of the design, other equipment and tooling were optimized or completed by themselves.

KT32F100 is designed exactly like the price of the ARM2 system, with a 32-bit data bus, 26-bit addressing space, and a 64 Mbyte addressing range with 16 32-bit scratchpads.

One of these scratchpads is used as a (word size) program counter, with the first 6 bits and the last 2 bits used to store processor status markers.

KT32F100 is probably the simplest and most practical 32-bit microprocessor in the world, with only 30,000 transistors. The reason for this simplicity is that it contains no microcode, and unlike most CPUs in later generations, it does not contain any cache.

This streamlined feature allows it to use very little power and perform better than the Intel 80286.
