Chapter 4: Z eighty processor

Li Xuan was stunned for a moment. He didn't expect his boss to agree so easily. In fact, his bottom line was 50,000 Hong Kong dollars.

Huo Junming didn't look at his usual amiable appearance. In fact, as a shrewd businessman, he knew very well what to fight and what not to fight. Compared with the millions of profits that can be brought to him every year by winning the agency rights, 100,000 yuan is only a small amount. Just like what Li Xuan said before, he has eaten meat in large chunks, and he still doesn't allow others to drink broth after him?

In contrast, he was more suspicious of whether Li Xuan could get the Hanka he mentioned. But these are things in the future, and now the most important thing is to contact the Japanese company to get the exclusive agency distribution rights. Whether Li Xuan can drink soup depends on his own ability. If it is really unreliable, he will spend a little more money to find a competent professional to make a Hanka.

"Well, okay, you are so refreshing, I am not ambiguous! You go to contact Japan Epson now, and it will take a few days for them to reply to you. I will quickly get the circuit design of Hanka ready. You When you go to Japan to negotiate, throwing this to the other party will give you a little more sincerity and confidence!" Li Xuan said loudly.

"Well, you have a lot of ambition, don't let me down!" Before Li Xuan left, Huo Junming said encouragingly behind his back.

"Vincent, what are you talking about with the old man inside? Why did you go in for so long?" Huo Junming's secretary Cao Yajing's desk is not far from the door.

"Company secrets, your level is too low to know!" Li Xuan said with a smile.

"Hmph, just trick me. Be careful that I will secretly give you small shoes in the future, and I will speak ill of you in front of the old and the young every day!" Cao Jingya rolled his eyes at him.

"The Amy I know is a kind and generous pretty girl, how could she do such a rude thing!" Li Xuan half leaned on the other side's table, not in a hurry to leave, "How about I bribe you? , please have afternoon tea!"

"Che, it's not sincere at all! I didn't invite me alone. Everyone in the company has a share. You think I don't know!"

"Hey, others are just ordinary milk tea, but I bought you bubble tea. Others only have pineapple buns, and you have egg tarts. Are you sincere enough!" Li Xuan got up and left, saying as he walked.

"It's almost there!"

Li Xuan and Cao Jingya teased a few words before returning to their positions. The military order he made in front of the boss just now, designing a Hanka is naturally not something that can be completed in a day or two.

In fact, he started working on it as early as half a month ago. The core of Hanka is naturally a chip that stores a Chinese character library and can process Chinese character information. The second is the integrated circuit board with the chip design.

This printer Hanka designed by Li Xuan is going to use the Z80 processor as the core. This chip was launched in 1976. The Zilog company that produced the Z80 was founded by several technicians who resigned from Intel. The design idea of ​​this chip is a copy of Intel's 8080 processor.

As a result, the newly launched Li Gui Z80 beat Intel's genuine Li Kui, and the only killer is the price. At that time, the retail price of the 8080 chip was $150 each, while the price of the Z80 was $25. The huge price gap between the two made Intel's 8080 chip instantly useless.

The 8-bit chip Z80 was later selected as one of the 25 most shocking chips in history. Even in the 21st century, 30 years later, it still continues to glow tenaciously on some low-end single-chip microcomputers. vitality.

Besides the consideration of low price, Li Xuan chose it because he is no stranger to the structure of this chip. When Li Xuan was in college, there were many Z80 single-board computers purchased in the 1990s that were idle and useless in the laboratory.

In a major assignment in a professional course, he also specially studied the feasibility of improving the backward Z80 single-board computer into an MCS-51 single-chip computer. To this end, he spent half a semester doing various experiments, and finally wrote a complete thesis. This paper was later recommended by the teacher to be published in the natural science edition of the university journal of our school. Therefore, Li Xuan is very familiar with the circuit structure and performance of the Z80, and is naturally more handy when designing the corresponding circuit board.

Before Li Xuan's rebirth, he was engaged in the bottom-level design of embedded systems, and both software programming and hardware design must be excellent. And hardware design naturally includes circuit board design. Designing a Hanka is really not difficult for him. Compared with the work before his rebirth, this task can only be regarded as entry-level difficulty at most.

But easy in theory does not mean easy in practice. The biggest problem Li Xuan encountered was that the development tools were not suitable. In the 21st century, circuit design has already entered the stage of computer automation development, and various CAD and EDA auxiliary software are very handy. Back in 1979, commercial computer-aided software had not yet come out, and the design and wiring of integrated circuits were mostly done manually.

Of course, if Li Xuan was in a big company like IBM and Intel, there must be design software developed by those companies and large computers for on-board simulation testing. But Li Xuan is now fighting alone, UU reading www.uukanshu. com This undoubtedly greatly increases the difficulty. Fortunately, the circuit diagram of this Hanka is not too complicated, and Li Xuan can barely handle it.

As for the negotiation with the Japanese, it depends on whether the boss Huo Junming can successfully convince the other party. If it doesn't work, all his hard work these days will be in vain. As for whether Huo Junming would turn his face over after taking over the distribution rights of Epson's MX-80 printer, Li Xuan thought it was unlikely.

Based on his own observations since he joined the company, although the boss is more shrewd in business, he is not the kind of person who cares about things, and he is more decisive in his work. This is why Li Xuan is willing to encourage him to go to Japan to talk about agency rights.

If the other party really kicked him away in the end, Li Xuan could only admit that he was unlucky. Who told him that his strength was not enough, he was not qualified to end up as a player, but could only be a small chip for others.

As for applying for a patent or something, it's not a very powerful invention, it's just a small application based on someone else's product. The design of the whole Chinese Hanka is largely based on the original Japanese Hanka in the Epson printer, and the line interface is also based on the interface of the printer, so there is no value in opening this printer.

And to some extent, Li Xuan's Hanka is suspected of plagiarizing other people's technology. If you really want to avoid his design, it is not difficult to redesign a Hanka.

So he never thought about applying for a patent at all. After all, applying for a patent is not free, on the contrary, the cost is not cheap. Even if you apply for a patent in Hong Kong, it costs a few hundred yuan, and if you apply for an international patent, you need to find a specialized agency, which costs at least a thousand yuan.
