An Italian-style mansion in Beacon Hill.

Fakin pushed open the door and entered the living room where the music was echoing, and there were two women sitting in front of the grand piano, one was his wife and the other was the teacher who had come to teach her Cantonese.

The music stopped, the two got up, the teacher bowed to him slightly, and then smiled goodbye, and Mrs. Farkin sent the woman away, came back and sat down on the sofa with her husband, and asked, "Federico, I've almost packed up the salute, do you have anything else to take to the United States?"

"Mom, can I take Lily to America too?" At the top of the stairs, a little girl broke free from the maid's arms, staggered over the gorgeous carpet, and threw herself into her mother's arms.

Lily, the neighbor's child, was the first friend of the same age the little girl ever met, and the two had grown close over the course of several months.

Faggin and his wife looked at each other with a hint of bitterness in their eyes, and the couple did not know how to explain the meaning of the intercontinental migration to their young daughter.

Seeing that her parents did not speak, the little girl obediently hid her head in her mother's arms and stopped talking.

Just seeing a chic letter on the coffee table, Fakin changed the subject and said, "What's that?"

Mrs. Faggin said lightly: "It's an invitation letter from the Chinese University, and they need a lecturer in European literature for the next academic year." ”

A smile appeared on Fajin's face, and then it turned into a wry smile: "Actually, it's good for you to teach, this is your dream in college." ”

"It's a pity it's not the right time...... "Mrs. Faggin smiled, got up with the child in her arms and told the servant, "Prepare dinner." ”

"Why don't we stay?" said Fakin as he followed them.

Madame Faggin turned her head and looked at him deeply, "Federico, you don't have to stay for me, just like you said, Xiangjiang is a desert for scientific research, and it is difficult to grow fruits. ”

Fa Jin hugged his wife and daughter, and said with some sadness: "The company rejected Zhang's request, and I went back to another project team to do it, and I suddenly felt that it was good to stay." ”

"Federico, can you design the product you want here?" said Madame Faggin, staring at him.

"It's difficult for the time being, Daheng doesn't have any technology accumulation, and there is no wafer factory here to foundry. Fa Jin said lightly, a fire dancing in his eyes, "But I think Zhang may be able to agree to my request, maybe we can try this option." ”

Madame Fakin's eyes were full of warmth and encouragement: "Perhaps...... Let's give it a try. ”

......

Not to Zhang Heng's expectations, Intel politely declined Daheng Technology's request to develop an exclusive CPU.

It may be that the two losses on the 4004 and 8008 customization have made them lose interest, or it may be that they have not yet seen the real prospect of an arcade machine with 8008 applied.

In Zhang Heng's view, the main reason is that Intel does not regard CPU as a mainline product, at this time, in their wafer factory, orders for RAM and ROM have been scheduled until the end of 74, and there is no time to consider large-scale production of other products.

You must know that Daheng's 8008 order is just a test factory, not large-scale production at all, and adjusting the wafer factory production line is a costly and cumbersome matter, and Intel cannot agree to design and produce a new chip without being sure.

This is actually Zhang Heng's intention, he did not promise the minimum production required by Intel, 100,000 new chips per year.

In addition, the letter of appointment of the Chinese University of Chinese was also facilitated by him through Professor Gao.

At this moment, in his office, he looked at Fakin with joy.

"If you want to stay in Daheng, that's great, the colleagues in the R&D department must be happy!"

"Zhang, I have one more request......" Fajin said in a hesitant voice.

Zhang Heng said briskly: "It's the salary, no problem!"

"No, I'd like to design this dedicated CPU!"

"It's not a big problem for you to take the lead in the design. Zhang Heng looked at him with a smile, "But there are too many problems that we can't solve for the time being, and the most important thing is who to find for production?"

The design of an integrated circuit, must be built on the existing production process, without the manufacturer's technical parameters, can not achieve a specific circuit, at this time there is no professional foundry, and Intel is obviously more willing to provide a mature 8008, Daheng Technology is likely to be just wishful thinking to do useless work.

Faggin hesitated: "Maybe I still have to talk to Noyce and them, and try to put it in their wafer factory tape-out, after all, my design is still based on the 8008 architecture." ”

Zhang Heng frowned and said, "I'm afraid that if you jump ship this time, what do they think." ”

Fakin also frowned and said nothing.

"I'll talk to Noyce about this problem, let's not consider the tape-out problem for the time being, you first set the general framework of the logic circuit. After thinking about it for a while, Zhang Heng said.

Fajin nodded: "Okay, then it's a matter of manpower." ”

He will assume the responsibility of the main designer of the new CPU, but the specific process also needs corresponding manpower, such as logic circuit designer, analog circuit designer, wiring designer, input and output designer, etc., and many new modules in the CPU may also involve existing patents, which need to carry out complex query and verification work, which also requires professionals to cooperate with lawyers.

"The manpower company will figure it out, and you can just check it when the time comes. Zhang Heng said that he decided to go to the United States again, and this time there are many problems to be solved.

"Okay, Zhang, let's talk about the framework of the new CPU. "Faggin quickly returned to the technical level.

Last time, all the members of the R&D department of Daheng Technology discussed it with Zhang Heng and sent it to Intel the new CPU design idea was based on 8008, adding some special circuits and internal registers.

In short, this CPU integrates display, sound and verification circuits on the basis of 8008, which is more powerful, but the circuit will be more complex.

As before, Fakin reiterated his reservations: "I think the overall cost of such an integrated chip will be relatively high, it is better to make each module into an independent device, so that the design difficulty will be much smaller, the production cost can also be reduced, and in this way, we can provide solutions for other products." ”

Of course, his design idea makes perfect sense, and it is completely correct when used to design computers, and he is a bit radical when it comes to arcade machines that need to prevent large-scale piracy.

"Federico, the market for arcade CPUs is going to be much larger than we imagined, and it is necessary for us to design a dedicated CPU for this purpose, rather than thinking about how to develop other generic products first. ”

Zhang Heng said very seriously, "When there are no other competitors entering this market, it is necessary for us to build a barrier with complex technology, and only after we firmly occupy a dominant position, can we consider simplification and optimization." ”

Fakin nodded silently.

"However, your idea is valuable, and when this generation of arcade machines matures, we will launch new products based on this idea, not limited to arcade machines. So, let's start with this CPU!"

Zhang Heng's words made Fajin's eyes light up.
