Zhang Heng did not participate in the signing negotiation with the Xu brothers, and handed over the matter to Tang Jihua and several other shareholders, Australian iron ore affairs do not follow people's subjective will, and the progress of various projects is fast and slow, and he can only watch from afar, at most call from time to time to understand and supervise.

Zhang Heng then put his focus back on Daheng Technology, specifically several projects of Daheng Technology.

The most important is naturally the new arcade chip project codenamed DHJ-73 spearheaded by Fakin.

"This is the overall framework of DHJ-73, which is divided into two parts: the core and the periphery, the middle part is the core processor, and the periphery includes the storage module, the sound module, the display module, and the input and output control module. ”

In the Daheng Science and Technology Laboratory, Fajin held a thin wooden stick and pointed on the blackboard, and below sat Zhang Heng, Lu Yuanteng, Herney, and more than a dozen young members of the DHJ-73 project team headed by Chen Zhefeng, a small part of them were dug from other local electronics factories, and most of them came from the Fairchild factory that Daheng Group had just taken over.

In the past few months, thanks to the full guidance of high-level veterans like Fajin, otherwise these engineers who have only learned ordinary circuit electronics would not have been able to enter the field of integrated circuits in a short period of time.

Zhang Heng was very satisfied with the selfless cooperation of Fajin, and felt that the options and other favorable conditions he paid were completely worthwhile, in order to show respect, he raised his hand to ask to speak, and said after getting Fajin's signal: "Federico, according to what you said, our DHJ-73 chip, including the core processor, will integrate all the five modules in one chip, is there any difficulty in circuit design?"

Fakin shook his head with a relaxed expression: "It's not too big of a problem in terms of design......"

According to what he said, this highly integrated arcade chip, only the input and output module needs to be specially isolated because of the existence of ANALOG (analog circuit) part, this part he handled with Herney, and the rest are all the most basic CMOS circuits, there will be no crosstalk, Zhang Zhefeng and his team have drawn all the circuit diagrams, and are preparing for the next step of computer simulation.

Returning to the core processor, Faggin added an address and data bus to the 8008 architecture, expanding it into a 16-bit data bus and a 20-bit address bus, which can support up to 1MB of external storage addresses, and also added a digital co-processor, which solidifies some of the advanced math functions that should be involved in arcade games.

In this way, the computing power and speed of this core processor will theoretically be increased by more than ten times compared with the 8008, that is, its main frequency will reach at least 8Mhz, and the maximum operating frequency of the 8008 used in the first generation of Daheng arcade is only 0.8Mhz.

"It's almost up to the 8086 computing frequency launched by Intel in 1978, but the Daheng chip also has an integrated audio and video processing part, which is much more powerful. ”

After silently comparing and calculating in his heart, Zhang Heng asked another question: "After the data bus reaches 16 bits, will there be a problem with the support for the corresponding peripherals in the future?"

"Boss, you mean that this chip might not only be used on our own arcade machine?" Fakin looked at him in amazement.

"As an effective whole, the DHJ-73 should only be used on our arcade machines, but the core processor in the middle, I intend to list it as a separate chip and sell it to the public. ”

Lu Yuanteng couldn't help but ask: "What if there are competing manufacturers to buy it?"

"Sell it too!" Zhang Heng replied without hesitation, seeing that everyone had incomprehensible expressions on their faces, he said with a smile: "Don't forget, through the acquisition of Mirohua, Daheng already has the most important TV game console patents, as well as contact cross resistance rocker and ball stick patents, if there are competitors, such as Atari, well, for the time being, we don't have time to trouble it, let's fatten it up first and then slaughter it." ”

Everyone in the room laughed.

Zhang Heng is really ready to fatten up Atari and kill it again, because Mirohua launched the arcade authorized by Daheng, Atari's "PONG" sales have been declining recently, and now the lawsuit will definitely not lose too much money, so it is not a waste of lawyer's fees.

On the other hand, Zhang Heng also wanted to see what kind of amazing ideas the genius founder of Atari would burst out in the adversity of the unfavorable start in this life, which can be regarded as some kind of fun for him, with a little weirdness and malice.

"Okay, competitors don't have to worry too much for the time being, I plan to sell this single main core to more manufacturers that need a complete industrial control system, such as Ford, such as Pang Dingyuan's steel plant. ”

Fakin thought for a moment and said, "In that case, our main core may be a bit overkill. ”

Zhang Heng glanced at him appreciatively, he was actually talking nonsense just now, the chip used in the industrial control system definitely does not need to be so complex and powerful, there are two directions he really wants to use:

The first is to actually sell to competitors.

Zhang Heng understands that even if Daheng wins the infringement lawsuit with Atari in the future, it is impossible for him to prevent Atari from continuing to develop and produce arcade machines, because of the huge anti-monopoly legal system, there is only one supplier of a product in the market, which is almost impossible.

There are also a series of large and small manufacturers such as Japan's Nintendo, and they will definitely jump into this industry that seems to be a blue ocean at present.

They will definitely buy patent licenses from Daheng before they put them into production, which goes without saying.

If you really want to hold the idea of eating alone, resolutely do not give patent authorization, then Daheng Group is equivalent to offending the enterprises of Japan and the United States, the arcade industry may be monopolized (but it will also be deliberately suppressed), and other industries still want to be mixed.

Therefore, instead of letting these competitors buy chips from Intel or other emerging companies, or develop and produce chips by themselves, it is better for Daheng to sell chips generously, which not only makes chip money, but also inadvertently promotes industry standards to favor Daheng.

In this way, Daheng's position as the leader of the arcade industry will be difficult to shake.

I can make you guys make money in the arcade industry, but I definitely make a lot of money!

Second, Zhang Heng plans to use this main core chip to try to build a general-purpose motherboard, so as to develop the world's first real personal computer (PC).

It turned out that the first real PC was successfully developed by IBM in 80 years and brought to the market on a large scale, using the 8088 launched by Intel in 1979, that is, the castrated version of 8086 (in order to adapt to the mainstream external equipment at that time, the 16-bit was changed back to 8-bit).

So why didn't Zhang Heng simply use the DHJ-73, which has a higher degree of integration and a more powerful functional module?

Because he deeply understands that making it big and looking beautiful and even monopolizing the entire motherboard is actually creating more trouble for himself.

Like audio and video processing systems, used in the arcade Daheng can develop and integrate by itself, but there is no need to hold on to the PC, it can be like the original time and space, so that each company can show its powers, and it is inseparable, as long as Daheng firmly controls the core CPU part, you can stand on a high place and overlook the show.

Of course, if the technical strength or economic strength is sufficient, Zhang Heng is not completely unmoved by other modules, such as the display screen and memory, considering the development of mobile phones in a few decades, he will still intervene in the layout early.

"Federico, you don't have to think about the usage level for the time being, and plan a small project on the main core first, I think it should be easy. ”

"I see, half a day is fine. ”

Zhang Heng nodded happily, he originally wanted to discuss the chip design ideas of different modes of instruction sets, that chip is going to be used in some scenarios where the operation is relatively simple and repetitive, there is not much market for the time being, there are many people today, or find an opportunity to communicate privately with Fajin in the future.

"Well, the problem is production. He turned to Herney next to him, "Is there a problem with the production of DHJ-73 chips in our factory?" ”

Herney frowned and muttered for a moment and said: "Boss, to be honest, there will be a big challenge, our factory has not fully understood the newly introduced CMOS process, maybe we can continue to use the HMOS process, otherwise I dare not guarantee the yield." ”

"Herney, the CMOS process has been determined, and this cannot be changed!" Zhang Heng shook his head slowly, his eyes resolute, "The launch date of the second-generation arcade machine corresponding to this chip is preliminarily scheduled for Christmas this year, I would rather have a very low yield at the beginning, and I want you to take this opportunity to understand the new process, and strive to fully exert the production capacity in the first half of next year, then it will be the sales peak of the second-generation arcade machine, do you understand what I mean?"

Herney nodded heavily: "Boss, I understand, I will take them to do a good job and live up to the expectations of you and the board!"

"So, that's it for today's meeting, I hope that in three days, I will see the layout of the two chips, and then I will personally go to the factory and work with the engineers to turn the layout into a mask map as soon as possible. Zhang Heng clapped his hands, "Thank you Federico and Herney for their efforts at this stage, thank you Zhefeng and our guys, the company will give double salaries to all employees in the laboratory this month to reward your hard work and outstanding contributions to the DHJ-73 project!"

"Thank you, boss!" Unlike the two middle-aged and elderly Americans, the young engineers did not hesitate to praise them.

"There's good news. Zhang Heng smiled and pressed his hands, "After the territory comes out, the laboratory can take annual leave in turn according to the group's welfare system, and be paid in full!"

Set a small goal first, such as remembering in 1 second: book guest residence
