The person who knows you best may be your opponent and of course your friend.

For Huaxin Technology, Intel will always be an opponent, and Texas Instruments can be said to be a temporary ally.

Just when Huaxin Technology was nervously testing the latest Athlon-2 CPU, Texas Instruments was also conducting corresponding tests.

The conclusions reached embarrassed the senior engineers of Texas Instruments.

"God, they've been able to stabilize up to 533Mhz. ”

In this era of frequency paramount, what does 533Mhz mean, it means that the crown of the world's most powerful desktop processor will be lost. This means that Texas Instruments will continue to be in a catch-up position.

"Why, with the same process and the same architecture, our best chips can go up to 400Mhz, but they, Huaxin Technology, can easily go up to 533Mhz. ”

Ignoring Director Camero's complaints, Clouen said to himself: "I can say responsibly that they must have adopted a pipeline deepening technology similar to Intel's Pentium II processor, and in addition, they have done enough optimization on complex instructions." ”

"This kind of technology, which we also use, is available in the Athlon generation. ”

"No, Mr. Camero, like the production line in the factory, the manufacture of a product can be divided into 10 processes or 20 processes. ”

This Camero naturally knows that assembly line technology is very simple to say.

The CPU handles ten additive calculations.

If there is no flow deepening technology, the CPU cores will be processed in turn according to the program settings.

In the deepening flow technology, the one-time addition calculation is divided into read_deposit_calculation_writeback

After the read stream has completed the read of one computation and handed it to the register, the second computation can be read without waiting for the first computation to be written back, and when the fourth computation is read, the first computation goes to the write command.

With such a design, the benefits are obvious.

Every computing resource in the CPU can be fully utilized.

There is no phenomenon of idle computing units.

In fact, this is how graphics cards are designed for a single task.

The difficulty faced by CPU deepening flow is predictable.

Well, the data processed by the CPU is not single.

Logical judgment, scientific computing, storage, and I/O device hardware management.

And many processes have a logical relationship with each other.

How to design this assembly line is not a very simple matter.

The purpose of pipeline design is to make full use of the existing resources of the CPU, if the design is unreasonable, repeated transfer, and endless loop, the original design purpose is often not achieved.

Texas Instruments naturally tried this and found this way after trying

In history, Intel was an expert in assembly line design, and at its craziest time, it designed 34 running water on the Pentium processor.

However, due to the low energy of the flow and algorithm design, Intel's processors have high scores and low energy, and the performance often lags behind competitors when the frequency is the same.

"Huaxin Technology can, and there is no reason why we at Texas Instruments can't do it. ”

Camero said seriously: "Now what I want to know most is the technical indicators of this CPU, how many stages of flow they have designed, how the computing processing unit room of the CPU is arranged, and why their frequency can go up to 533Mhz." ”

"We need time!"

"Well, you need time, one year is enough, three years is not enough, at that time, Texas Instruments, will be out of the CPU market again. ”

“......”

............

In Huaxin Technology, there is also a discussion based on deep pipeline design.

"Mr. Wang, based on the 180nm manufacturing process of the CPU, the 28-level design of the pipeline is not necessary at all, according to the simulation results, we cannot make an accurate judgment on the branch, which will seriously drag down the CPU core processing efficiency. ”

Wang Anran shook his head, Zhu Chaojie's judgment was correct, but he still decided to do it.

Why?

Quite simply, the 180nm manufacturing process of the CPU is to break through the 1Ghz frequency mark.

It is an opportunity for Huaxin Technology to reach the top.

And after the release of this CPU, the relevant data will definitely be announced.

Wang Anran's purpose is very simple, that is, to lead the opponents to a point of no return.

That is to give them the illusion that deepening the assembly line will be the direction of future processor development.

In fact, the once glorious Core processor uses only sixteen levels of pipeline depth.

It is necessary to deepen the flow technology, but after more than one degree, the difficulty of the design will increase exponentially, and the improved performance will increase at a turtle rate.

It is necessary to dig a hole.

Wang Anran thinks so, after the release of the second generation of Athlon, Huaxin Technology is naturally the target of its peers, and it is what Huaxin Technology should do to guide them to a "clear road".

Otherwise, with the strong R&D capabilities of the foreign semiconductor industry, sooner or later, all of Wang Anran's technical reserves will be hollowed out.

"It's a day to be able to drag it out!"

Wang Anran said in his heart.

There is no breakthrough in its own CPU production, but it is important to stay ahead of the curve in chip design.

At least there is the ability to bargain with these giants.

"I think the potential of deep flow technology has not yet been fully explored, and the CPU with 180nm manufacturing process will be the benchmark for desktop/server processors in the world, and it is necessary to create a collection of the top technologies of Huaxin Technology. ”

"But Mr. Wang, we use the existing mature 18-stage assembly line design, which can also achieve the expected goal, and I think it is still possible to break through the frequency of 1Ghz. ”

"You said it too, it's just possible!

Zhu Chaojie shook his head, he just put forward his opinion, and when it comes to this, there is nothing to say.

The decision is the boss's, and the boss bears the responsibility for mistakes.

And if it is replaced by oneself and something goes wrong, I will definitely not be able to bear this responsibility.

"Got it!"

Wang Anran took a sip of water, watched Zhu Chaojie walk out of the office, and suddenly thought, what is the old rival Intel doing?

Now the next-generation 320nm manufacturing process has begun to be tested.

The Pentium three processors have also entered the final test.

The development of chip technology is advancing rapidly, and before mastering the core chip manufacturing capacity, Wang Anran does not know how long Huaxin Technology's current leading edge can be maintained.

Two years from now, will Texas Instruments be as obedient as it is now, OEM the most advanced technology products for Huaxin Technology?

It's a big head to think about, but what comforts him is that at least Huaxin Technology has sold a solid step.

And according to the news from Dajing Zhang, a paper on the BSIM mathematical model of the new FinFET transistor has been published.

"Anran, tell me about it, how can you thank me. ”
