Blooming America

At the end of the month, the Xunlei Laboratory, which belongs to the intee company, was in joy at this time.

"Sacrifice energy is not bad."

Catherine is also here at this time, and her eyes are full of light.

The highest frequency of the trial-produced Capricorn once reached 100mhz, but that was only a very small number of super high-end cpus, it can be said that it is the limit that the cpu can reach now.

As for the current high-end cpu, the highest clock speed is only abusive, while the general product is about Weiwang.

In front of Catherine's eyes is the 42mhz version of the flagship version that will be promoted to the market.

There is a big difference between laboratory products and official products.

And even intee, dare not immediately launch 100mhz products.

After all, this is almost ten times the xìng performance of current mainstream CPUs, and most importantly, this is a 32-bit system CPU.

This also means that there will be a cliff that cannot be crossed between the two.

And right now, the introduction of a new cpu with a minimum of 10mhz is also to turn the gully into small

Slit.

In this way, it is conducive to product promotion.

Over-advanced products will cause a series of terrible problems, and these problems are likely to be fatal.

Katherine can make the CPU appear early, but it is impossible to develop these products faster.

It's as if intee has long developed a 100ghz optical processor in history, but used it as a technical reserve. It would rather develop an ordinary processor with the iuy architecture than launch such a killer optical processor. Too sturdy equipment will push the enterprise itself to the edge of the cliff.

The 100mhz product was launched as the next generation product.

According to Catherine's idea, a first-generation product, the zodiac sign, will be launched in about a year and a half, which is a total of 36 years.

Well, wait until all the zodiac signs are released at the end, then steal a lazy launch of a new zodiac sign, and then turn a set of twelve old unsold CPUs into "collectibles of the year"

Then take it to auction...

Catherine's wishful thinking is crackling.

"If the experiment is 100mhz, can it be stable?" Catherine asked.

"There are still some problems in the process." Robert replied: "Although the frequency is high, the problem of heat dissipation is very big. Also, this cpu often fails to cause crashes, and it runs at such a high frequency. There will be many defective products during production... Therefore, if a 100mhz cpu wants to be launched, at least it has to wait until the process is mature one year later or a new process is adopted-then high-frequency cpu may be promoted to market."

Catherine nodded.

Originally, she wanted to get a 100mhz cpu in her office, but when she heard the problem of frequent errors and crashes, Catherine felt that she would still choose a 42mhz product...

It is rare that Catherine wants to enjoy special treatment as a boss, but it is a pity, but the fact is not as good as she imagined.

"If possible, our next-generation products should not be entangled with the main frequency. We have to consider the proportion of GPUs in our processors. The next generation is not only this generation, we will call the products that integrate cpu and GPUs. It is now an apu, and both cpu and gpu will exist as processing units."

Catherine's thoughts, Robert felt deeply impressed.

The frequency of the current machine is sufficient. After the process is mature, the 100mhz cpu can be promoted. In fact, even if the process is mature, you may have to wait until the market can accept it before launching to achieve the best results.

At this time, it is obviously unwise to continue to increase the frequency.

To be good at work, you must first sharpen your tools. It may be better to mature the new apu architecture.

Therefore, according to the plan, the next-generation CPU will not increase the clock speed, which means that the highest clock speed of the next-generation computer will also be 100mhz.

But the next generation of cpu will also undergo a revolution in creation and change.

Generally speaking, cpu is good at task allocation, data pre-reading, decoding, branch prediction, etc.

And Catherine's goals for these researchers are also in these aspects.

The GPU has strong floating-point computing capabilities. Although Capricorn integrates cpu and gpu at the same time, the two are still working. Although there is a cuda architecture, in many cases, this architecture cannot be used to perform on the cpu. Enhanced, in fact, cuda is generally only effective for external graphics cards.

And because of the limitation of the architecture, even if it is used in the cpu, the improvement efficiency obtained will be very limited.

This is a little far away from Catherine's idea. According to Catherine's idea, a processor that integrates gpu and cpu should be a bit more awkward.

In order to achieve the goal of improving xìng, Catherine decided to streamline the task of the cpu to pre-reading and decoding, and the gpu will be responsible for the main calculation work, so that the cpu becomes only pre-reading and decoding data for the gpu, and the gpu is It runs at full speed and becomes the center of computing. If it can be realized, the computer will gain more than 20% of the xìng energy increase.

Let the gpu core perform computational functions, while allowing the cpu to prefetch the gpu from the off-chip main memory

The required data. This is more efficient because it allows cpu and gpu to do what they are good at: gpu's strengths are calculations, and cpu is suitable for making decisions and fetching data.

In fact, the speed at which cpu and gpu get data from the main memory is about the same, but if the cpu can be allowed to determine the data required by the gpu in advance, and use it to prepare, the gpu can reduce the burden and devote itself to execution and calculation. Go, efficiency can naturally be improved.

In a gpu processor assisted by the cpu, after the cpu starts a gpu program, a pre-execution program is created. The program is automatically generated from the gpu kernel using a compiler algorithm, and contains memory access instructions for multiple thread blocks of the gpu kernel. The cpu pre-execution program will run before the gpu core. This is because: first, the cpu pre-execution thread only contains the memory pickup instructions from the gpu core, and there is no floating point calculation: second, compared to the gpu scalar core, the cpu runs The frequency is higher, and the parallelism of the instruction level is also higher.

It doesn't matter if you don't understand, just know that it sounds like a great deal.

The grievances of science students will not be understood by liberal arts students.

All in all, in the new cpu, the proportion of cpu and gpu will become equally important, as if the weights on both sides of the balance are the same weight, balance is the king.

In addition, another technology will also be applied to the new cpu, that is frequency multiplication technology.

The frequency doubling technology is still in the research and development process, but this technology is not difficult to research, so it can be developed quickly.

With the frequency multiplier, there is no need to worry about the frequency. As long as the frequency can be doubled, the maximum frequency of the cpu will reach 200mhz.

Of course, this frequency doubling technology cannot be used immediately.

Even for a new generation of CPUs, frequency multiplication technology will only be possible in high-end products and flagship products. As for the normal version, it is completely impossible.

Catherine analyzed the current situation, 100mhz cpu has been developed for half a year, but the researchers can not continue to increase the frequency, which means that the main frequency of the cpu has been increased and has fallen into a period of stagnation. If there is no way to find more Before advanced technology and architecture, it was impossible to increase the main frequency.

So after Capricorn, the main work of intee will be to improve the efficiency of the processor, not simply to increase the main frequency. Efficiency is also very important. It is as if a 3.0GHz i3 processor is more efficient and smoother than a dual-cpu system using two Pentium 5.0GHz.

More importantly, Catherine has decided that the frequency multiplication technology will be the main function of the next generation of CPUs. It was naturally impossible to popularize this technology before. In fact,

If Catherine started to make a cpu, so far, she should have developed a more perfect cpu. You know that historical intee has spent so much time, and already has a 386 cpu.

The cpu of 386 is not inferior to Catherine's Capricorn. In fact, if it weren't for Capricorn's integration with gpu, it would be better for Capricorn to be able to go to ~www.wuxiaspot.com~.

But after Capricorn, the situation will completely change. The new generation of CPUs will take a completely different path from the historical products. This path was completely developed by Catherine. This will be a path that no one has ever walked. path of.

Now, as long as the operating system x- is developed, Catherine’s Capricorn will be listed on the market.

At this time, intee's research and development work has shifted to the core of a new generation of processors that can be better developed by gpuxìng and xìng.

The new generation of apu will be named-Aquarius.

The plot of [China] will not develop further, and if it develops further, it will become harmonious after being reported.

So the last chapter can only come to an end.

Two more completes~

Next week, I will prepare an entire e3-1230v2 computer. I will remove all the SSDs of the notebook! .
