When CPUs first developed, the main frequency of the CPU was equivalent to the FSB frequency of the front-side bus, which was equivalent to the frequency of the device bus interface.

Later, the interface frequency of the front-side bus and the device bus could not keep up, and the main frequency of the CPU became the frequency of the front-side bus multiplied by the frequency of the double, and the frequency of the CPU and the front-side bus at this time were the same.

After that, the frequency of the device bus can not keep up, the main frequency of the CPU is equal to the external frequency multiplied by the frequency double, and the front-side bus is higher than the external frequency.

Figuratively speaking, the main frequency of the CPU represents the ability of the CPU to process in one second, the external frequency can be regarded as the pipeline for dealing with problems, and the frequency doubling is that there are several pipelines.

This involves a topic among DIY enthusiasts, overclocking.

The meaning of overclocking is to get a distinguished service at a normal price, and the starting point is nothing more than two, one is super foreign frequency, and the other is super multiplier.

Compared with frequency doubling, the external frequency involves not only the CPU, but also the front-side bus and the PCI interface of the device, which is naturally much more difficult.

In terms of CPU design, this is also a helpless move for the CPU's powerful throughput capacity to take care of other bus interfaces.

If it is a simple frequency doubling design, Wang Anran will naturally not make a big splash.

"Ladies and gentlemen, it's not just the frequency doubling design, we also have to redesign the bus interface, and we are the pioneer in the 180nm manufacturing process.

Director Gu also said just now that the current bus interface of 1Ghz CPU can no longer meet the needs.

Not only FBS, but also the serial bus interface can not meet the needs of our graphics card, we need a new design!"

"A new design?"

Wang Anran nodded and said: "At present, not only the PCI interface but also the AGP graphical interface that Intel is now promoting, all of them are using a shared parallel bus architecture, and the PCI host and all devices share a common set of addresses, data and control lines.

This poses a problem, as the number of devices increases, the bandwidth allocation will drop dramatically, and multiple devices will also affect each other. ”

How to solve it? There are a lot of smart people in Huaxin.

On this occasion, how many people want to show in front of Mr. Wang.

Zhu Chaojie, a senior engineer, said: "The parallel PCI bus has only one address, and all devices are connected to the host through this address.

In the past, when the bus bandwidth was limited, it was indeed a helpless move to adopt this method, but now that the performance of the CPU and bridge chip is rapidly improving, the original design still cannot meet the needs.

My vision is a multi-address shared host connection, where each device can communicate with the host. ”

Wang Anran nodded and wrote down the name Zhu Chaojie, which has clearly stated the characteristics of the PCI_e, and the main difference with PCI is the point-to-point topology.

Wang Anran likes to talk to smart people, and it is clear that PCI-E is not only an expansion and supplement to the PCI interface.

For Huaxin Technology, DDR memory is still a half-covered face with Intel.

The PCI_e interface is the first time that Huaxin Technology has started a battle with Intel.

The reason for choosing PCI_e interface is not only on the graphics card, but also because the existing PCI bandwidth can no longer meet the needs.

More importantly, Wang Anran is now going to lay out the development of solid-state drives, in terms of interface, the current speed of IDE is only 66M, and after the development of 2000, it is only 133Mhz, which cannot meet the needs of solid-state at all.

It's always good to be prepared, and you won't be led by Intel by the nose after the solid state comes out in the end.

And that day is not too far off.

At the end of the CPU product demonstration meeting, the following preliminary research such as technical implementation analysis, Wang Anran will not start in person.

In fact, Wang Anran is also doing chip design, and his mind is now completely immersed in chip production technology......

……

In the eyes of the outside world, Huaxin Technology has been low-key enough in the near future, because it has no capital or is holding back its big moves, and everyone has everyone's opinion.

After all, Huaxin Technology's CPU was pressed to the ground by the third-generation Pentium 586 processor, and Huaxin Technology's graphics card was beaten by Nvidia's TNT graphics card.

In such a situation, the people who eat melons are naturally welcomed, and they didn't see the original high-flying Pentium processor, and now the price has dropped to 1500 yuan.

And the original unattainable Ripper 107 graphics card, the price has also fallen below 1000 yuan, and now you can save a computer that can play Counter-Strike without much effort.

However, it is not so polite in the media, Apple Daily directly and publicly called, Huaxin Technology has exhausted its talents, China's chip industry is short-lived after all, and it is time to face up to reality.

If that's all it takes, this bullshit newspaper also brought up the patent dispute between SGI and Intel again, vaguely saying that Huaxin Technology's products are plagiarizing SGI and Intel's patents, and as for the settlement, it is because of the benefits that satisfy the two giants.

Moreover, Apple Daily also pointed the finger at the country, saying that the background of Huaxin Technology is the country, and Wang Anran, including the current Rebus, is just a puppet......

……

When he heard this report, Wang Anran was eating breakfast, swallowing a poached egg and drinking a mouthful of mutton soup.

Apple Daily, he knows, the little cub of the British, in the industry, is famous for biting dogs.

Most Chinese people and institutions often swallow their anger and don't care about it when they encounter such a little cub biting, but Huaxin Technology is not used to it.

"Let's also advertise in the Island Daily!"

Rebus swallowed a mouthful of fritters and asked, "What advertisement?" ”

Wang Anran wiped his mouth with a towel, burped, and said: "Arrange half a page, put a picture of a middle finger on it, and publish a sentence: Fuck Apple Daily." ”

Rebus almost squirted out a mouthful of soy milk, and hurriedly said, "Mr. Wang, is this okay?"

"What's not okay, some media just don't scold, if you get used to it, he will be even more arrogant. ”

Rebus looked black and said: "Apple Daily is a piece of, and we Huaxin Technology are lifting them up." ”

"Well, or in your name!"

“……”

Wang Anran looked at Rebus's loveless appearance, and knew that intimidating people was not his forte.

"Okay, add one more me, I'll give you a platform, sometimes, you don't care about others, people don't think you're magnanimous, but think you're afraid of it, and the next bite will be more fierce. ”

"Mr. Wang, I want to just vent it verbally to get a good time, such an unscrupulous media, no matter how you say it, you have to make him pay a price. ”

"Of course, what do you think?"

Rebus said: "Isn't Hong Kong Island paying attention to the law, let's think of a way in the law, how to say this also constitutes a slander of the image of Huaxin Technology!"

"This can be had, hire the best lawyer, and try to make them pay tens of millions!"

If this media is directly shut down this time, there will be a lot less in the future.
