The development of technology in the semiconductor industry is changing with each passing day, and new technologies are produced almost every day and every hour, although not every new technology is advanced technology, but the number of patents applied for by Intel and NVIDIA companies every day has invisibly put a lot of pressure on Wang Anran.

Wang Anran put the report of the Ministry of Information on the table and took a deep breath.

"Huaxin Technology is now like a catfish in the water, making the already active fish pond more active. ”

"Intel is now like a chicken, and there are dozens or even hundreds of technology patents applied for every day!"

In this way, it will not be long before Huaxin Technology will have no way out, and the patent barriers of the original plan will be impossible to talk about.

Shaking his head and sitting in his chair.

Li Qiusheng didn't dare to say a word, in fact, he just came over to deliver a report.

"Mr. Wang, if there is nothing else, I'll go back!"

Wang Anran nodded, thinking about the original Intel's technology development route, and Huaxin Technology might overtake in a corner.

At that moment, there was a knock on the door.

"Mr. Wang, you call me!"

Wang Anran stood up and said with a smile: "You are the master of Xinyan, Lu Xiaochuan, right!"

"It's me, Mr. Wang!"

"Sit, sit down!"

Pouring water, Wang Anran said: "I just talked about you with Xinyan, and we seem to have a common opinion on assembly language!"

When it comes to professional content, Lu Xiaochuan is a lot more relaxed, and he is not as restrained as when he first came in.

"Mr. Wang, assembly language, as the language closest to the bottom, I think it will be of great help to our research on chips, and it is a shortcut to get started quickly for novices, and of course, it is also the most basic. ”

Wang Anran nodded, in fact, many chip design practitioners have a very narrow understanding, and some are only proficient in EDA software, Verilog HDL and other circuit design languages, and when the designed circuit has a problem, there is often no way.

"Circuit design software is designed by people, it is difficult to consider the complete situation, under special conditions, hidden bugs will appear, which requires not only experience, but also requires extraordinary sensitivity and proficiency in the underlying code and logic circuits. ”

……

"Who's in there?"

"It's Lu Xiaochuan of the microarchitecture technology group!"

"How long?"

"It's been almost three hours!"

"Three hours?"

The other nodded.

Xue Jin couldn't help but panic for a while, and his brows furrowed.

Just kidding, the boss went to inspect his own department, and didn't let himself, the minister, report to his work, but found Lu Xiaochuan from the technical group, what is the situation, are you not satisfied with yourself!

There is no way, since Mr. Wang directly accepted the microprocessor division, the leader seems to have to change constantly, which can't help but make Xue Jin think wildly.

Half an hour later, the door to the conference room opened.

Wang Anran walked out the door and saw Xue Jin standing not far away, waiting, this scene made him frown.

In Wang Anran's view, a minister's job is to stick to his post, not wait for him here!

"Minister Xue!"

Xue Jin hurriedly trotted forward all the way and said, "Mr. Wang, you are here to inspect the work!"

Wang Anran nodded, he didn't want to say anything, turned his head to Lu Xiaochuan and said, "Go back first, I'm delaying your work!"

"No, no, don't delay, Mr. Wang, then I'll go first!"

Wang Anran also turned his head and left.

Looking at the current situation, the R&D team of Huaxin Technology does not have the ability to innovate alone.

Under the existing architecture and conditions, the R&D department can make the CPU to the extreme, but when it comes to adjusting the new architecture and new bus technology, it is a bit inadequate.

Waiting for it to be cultivated slowly, the daylilies are cold.

Wang Anran returned to the office, thought about it, and still copied the homework first.

After thinking about it again, I decided to start with the hard disk interface.

For no other reason, FinFET stacked flash storage has matured, and it can achieve eight layers of 180 nanometers stacking in its own laboratory, and theoretically 16 layers and 32 layers can also be achieved.

Suffering from the relatively backward manufacturing process of Huaxin Technology, it has not been realized.

In the tape-out test of memory chips, the speed of reading and storage has exceeded 100m/s, and the original IDE interface no longer meets the requirements.

The design of a new interface requires a new bus design, and the bus also affects the design of the CPU.

On the second day, Wang Anran convened a meeting of the members of the bus R&D group, the microarchitecture R&D group and the FINFET business group.

"As early as the beginning of the year, the research and development task of the storage device interface has been arranged, and we have a meeting today to understand the development of the project, and on the other hand, I also want to discuss with you in detail the follow-up development. ”

Chen Lan, the backbone of the bus R&D team, said: "Mr. Wang, we have designed a new parallel port control protocol, which is specially optimized for the current IDE interface bus data tolerance and transmission interference, and it is worth mentioning that we have raised the existing 8-bit parallel port to 16 bits, and the speed of a transmission is twice as fast as the original......"

"What about interference, how to solve the frequency of transmission?"

Wang Anran directly interrupted Chen Lan's speech and continued: "Professor Chen, I remember that when I assigned the task, I specifically mentioned that we can refer to the transmission method of optical fiber, is there any argument for this?"

Chen Lan shook her head, unconvinced, and said secretly: "You are the boss, you have a big mouth, and people who understand technology know that who is faster in the end of transmitting 16-bit data at a time and transmitting 4-digit data at a time, just like an eight-lane road and a two-lane road, who has a large traffic flow, does this still need to be demonstrated?"

"So, you didn't do anything and vetoed this plan?"

Everyone is engaged in technology, the pride of the sky, Chen Lan rushed up in one breath, and immediately said: "Mr. Wang, optical fiber and wire are fundamentally different, one is to transmit optical signals, you must know that light is not electromagnetic induction, so there is no interference, and wires, whether it is 4 bits or 16 bits, high-frequency electrical signals, will inevitably produce interference, I don't think 8 bits to 4 bits or 2 bits will produce much speed increase, all, I think, we don't need to focus on projects that are doomed to failure." ”

"Failure, how do you know failure, Chen Lan, you have done a test to demonstrate, you have not tried it, how can you conclude that it is a project that must fail!"

Although SATA bus transmission is also used as a transitional solution, it will eventually be replaced by the nvme interface PCI bus, or it cannot be said to be replaced, SATA will always exist for a long time, because it can be used as an interface for high-speed mechanical hard disks.

This is the demonstration of countless companies, the original SATA alliance, can include Seagate, intel, AMD, IBM and a series of industry leaders, in fact, it is also proven to be stable performance, the most economical solution.

You know, "the most economical", this is the most direct indicator to consider a technology, and SATA contemporary, there are many bus transmission technologies, their performance is even faster than SATA, more stable, but all lost to the SATA protocol.

Another example is the same for Huaxin Technology's core technology DDR memory, in terms of performance, whether it is latency or same frequency transmission speed, it is slightly inferior to Rambus memory, but the manufacturing cost is only one-third of Rambus, providing similar performance, which is the biggest killer!
