The bug of Pentium microprocessor originated from Intel's multiplication tables being solidified on the chip in order to improve performance.

This was originally a good design, but 5 of the 2o48 numerical terms in the multiplication table are wrong, which leads to the incorrect results being obtained in some rare floating-point operation scenarios.

The situation is similar to a master of abacus, who is very good at planning and invincible, but he just remembers a few wrong melody.

To give a specific example, when the number 3145727 is used to remove 4195835, the calculation result starts from the back of "1.333", and there is a large error.

A professor in the United States encountered confusion when enumerating prime numbers through computers - how can the same mathematical algorithms have different results with a high-end Risc square computer using a ho1der microprocessor and a mid-range Cisc computer using a Pentium microprocessor?

After a lot of trouble, he confirmed that the Pentium microprocessor had chip flaws and sent an email to Intel to report.

In fact, this bug has been discovered earlier in Intel.

According to an engineer, this bug will cause an error in about every 900 million long division operations.

Convert this data into a more vivid statistical caliber, that is, the average fault interval is about once every seven hundred years.

The conclusion is that this bug is almost impossible to occur - but in reality, it is still discovered, and some people claim that they encounter this error much more frequently.

Intel seems to be slow and even a little stupid in handling this matter, otherwise it would not have given an excuse for an average failure interval of 70 years.

Don’t forget that now is entering the Internet era. It can praise you to heaven or scold you as a dog. Intel’s arrogance has attracted overwhelming condemnation from the virtual community. So much so that in real society, professional computer magazines such as Byte and extremely influential media such as Cable News have conducted comprehensive reports.

This bug has been affected by the product, basically covering O.8 micron process and O.6 micron process, and a Pentium microprocessor with a running frequency of less than 12omhz, which can be said to be a serious disaster.

Intel, which has many reasons to make excuses, doesn't matter if its reputation is bad, but it has also affected the personal computer industry, which scared many customers and did not dare to buy computers that use Pentium microprocessors or even the entire Intel family microprocessors.

You should know that in specific daily applications, the operating system's own calculator, spreadsheet software, etc. will call the built-in instructions of CPU. If the financial statements unfortunately encounter this floating-point operation bug, it is hard to say the problem.

I have to say that Intel is really not a good deal of public relations. In addition to being judged by users, media, etc., on the moral commanding heights, it has also attracted a lot of complaints from the industry.

It's so annoying when this crisis occurred.

No matter what the actual product is, it poses a visible threat to PC at least in terms of momentum. Fangyuan personal computer's ho1der product line is aimed at the mid-to-high-end, and the Pentium product line is the main force in fighting against NC and competing for market share. Now Intel has lost its chain, which has caused everyone to fall into a dilemma.

In this case, Mr. Fu rarely issued a leader order, convening major hardware and software manufacturers in the personal computer industry to gather in Cupertino to discuss how to clean up this unexpected chaos - not to give Larry Ellison the opportunity to take advantage of the situation.

Tang Huan's attitude is very clear. There is no other solution. There is only one way to recall the product. Now it is not a problem with an average failure interval of 700 years, but the outside world's impression of Intel and confidence in the product has a crisis.

The reason is there, like buying a product online in time and space, except for the broken packaging and suspected second-hand goods, there is no problem. You can see what customers give them.

Intel CEO Andy Glov also saw the current situation clearly, but he still couldn't overcome that hurdle.

At a small meeting, Andy Glov said to Tang Huan with a bitter face: "If the product is recalled, the related financial losses may be over 500 million US dollars."

Fangyuan Company John Chambers said in dissatisfaction: "You see Intel's economic losses, but you don't think about it. In the face of the NC challenge, how much time will it take to replace the bug-affected Pentium microprocessor with bugs in the PC industry? How many opportunities will it take to replace the bug-affected Pentium microprocessor?"

Andy Glov's temper is famous for being tough, but now he is really too inappropriate and can only be silent.

"No one wants to do this. Everyone wants to make money peacefully, so let's look forward." Tang Huan waved his hand and said in a deep thought: "Although it takes a process to replace the Flawless Pentium Microprocessor, the user's direct user experience depends largely on the software."

Andy Grove, who was in a state of high operation for a while, quickly realized, "Tang meant that the Pentium Floating Point can be controlled from the operating system level to eliminate the adverse effects of errors?"

Tang Huan nodded slightly, "Zheru software has undergone technical evaluation. In addition to being able to identify the floating point, in addition to the wrong Pentium microprocessor, it can also temporarily bypass the problematic multiplication table in the form of sacrificing performance to achieve data security."

Speaking of this, Tang Huan emphasized his tone and pointed out: "But you have to understand that this is just a temporary measure. Intel cannot waste the buffer time that he has finally won."

"Intel will definitely seize the time and recover its mistakes." Andy Glof, who breathed a sigh of relief, solemnly assured: "The Pentium microprocessor with the new core p54c is ready to replace the p5 core product. It's just that the product recall is a bit economic pressure."

"I can help you find funds." Tang Huan comforted Andy Grove and turned his eyes to John Chambers, "Fangyuan Company can also support it, just treat it as the next generation netbsp; John Chambers did not object, but just reminded Andy Grove, "Intel promised a new microprocessor with built-in native multimedia instructions, no mistakes can be made."

Andy Grove agreed with ease, not caring about the unceremonious warning in the other party's words.

It has to be said that compared to the original control of time and space in the personal computer industry, Intel's current position has fallen to a level directly - it depends on Fangyuan Company's expression.

After reaching an agreement on this small-scale meeting, Tang Huan began to chair a larger industry meeting to coordinate various affairs.

Because the cost of the Pentium microprocessor recall was solved by Intel and Fangyuan, the other companies were not burdened with each other, and it was completely within their acceptable range. In addition, the atmosphere of the meeting was not as heavy as many people had imagined before. After a brief debate, they raised their hands unanimously and accepted the work they undertake, which was enough to release news to the outside world.

The large number of journalists squatting in Cupertino were very surprised by the degree of this meeting. Until they were arranged to be in the conference room where the press conference was held, they still looked surprised.

The protagonist Andy Glov sat in the middle. He seriously announced that Intel is a responsible and great company. In order to eliminate user doubts, he decided to recall the flawed Pentium microprocessor without regard to gains and losses.

This passionate statement really touched many people.

But someone still asked sharply - what should I do after the flawed Pentium microprocessor is recalled? Will it flow back into the market after being "polished"?

Andy Glov bit his back teeth and replied: "To make everyone feel completely relieved, this batch of flawed Pentium microprocessors will be destroyed in a centralized manner."

Seeing that the atmosphere of the press conference was a bit tragic, Mr. Fu interjected: "I have a suggestion, I don't know if it works - this batch of flawed Pentium microprocessors is better to make creative small items such as keychains as souvenirs for everyone."

...

The following is the anti-d part, updated tomorrow morning, and ignore it directly.

...

Tang Huan, who had foreseeed for a long time, was not surprised. He just held a media briefing based on feedback from the public relations department, and gave an official attitude on recent hot issues.

It can be imagined that Zheru Software Company has been taking the blame for its continuous actions in open source during this period.

Tang Huan, who is also the CEO of Zheru Software Company, opened the microphone and talked: "For a long time, there has been a very strong voice that accused Zheru Software Company of its actions, which is an intrusion with ulterior motives. I think this is unfair and even too extreme."

"The commercial success of Zheru Software Company cannot be the reason and motivation for malicious speculation about it. It is precisely because of this kind of commercial achievement that Zheru Software Company hopes that the entire industry can develop better - everyone understands the truth that the skin is gone, where will the hair be attached."

"Zheru Software Company has been paying attention to the software open source movement for a long time, so after careful evaluation and affirming its positive significance to the entire industry, it has made some attempts."

"Here, I don't want to show off anything, I just want to emphasize that doing is better than not doing it."

"I don't hide it. Zheru Software Company does not, and dares not open source the latest version of software products. However, Zheru Software Company is trying to share source code with its partners. However, the main driving force for doing so is due to the consideration of commercial interests in software engineering and the simple concept of the software open source movement, which is obviously different from the simple concept of the software open source movement."

"From the current results, Zheru Software's open source measures have played an active role at least in education. We are deeply pleased with this and have a clear conscience."

"I personally believe that the advocates and leaders of the open source community at this stage should focus more on how to improve the licensing agreement, so as not to use the free public resources of the open source community to obtain a mature and stable code base, and suddenly change the course and transform it into a closed source commercial product."

Speaking of this, Tang Huan shrugged, "I think this is something that people with ulterior motives should really worry about."

In the midst of laughter, the curiosity about Zheru Software's participation in the open source movement disappeared suddenly - and the window paper was poked so big, so what's the mystery?

Next, a financial reporter asked about the listing process of Zheru Software Company.

"According to the schedule, Zheru Software Company will be listed at the right time next year. I don't have more details here. If you are interested, you can pay attention to the company's subsequent public information." Tang Huan added after a clear answer: "Zheru Software Company is preparing to move to have a headquarters that belongs entirely to its own."

When he heard this, someone immediately linked it to the April Fools' Day joke that was so popular that it was moving on the spot, so he quickly asked the difference between the two.

Tang Huan replied in a natural tone: "Zheru Software Company will operate in a new posture as a public company, move out of Cupertino, get rid of the influence of the old management mechanism, and achieve maximum independence, which should be a wise decision."

The reporter asked relentlessly: "What was the reason for moving to the Rockefeller Center in America Online? There are rumors that you will buy the Rockefeller Center, is it true?"

"American Online's decision was naturally for the needs of developing its business. Acquiring the Rockefeller Center was a very challenging thing." This time, Mr. Fu's answer was not so pleasant. The unpleasant performance of the dragonfly skimming the water and the fog made the reporter feel very tickle.

Tang Huan then coughed lightly and said, "This time I met you to discuss the issue about Zheru Software Company. Please do not deviate from this center when asking questions from media friends."

"I can disclose to you some of the latest developments in Zheru Software's products. For example, a batch of 'i' products will be released in 6 consecutive times."

"So, what does 'i' mean?" asked listlessly.

Mr. Fu replied with a thrilling look: "One of the meaning of 'i' is 'internet'. For example, the upcoming Zheru office software suite is called zeroone_office_i, and according to the positioning of the enterprise version, professional version and personal version, it has the difference between i7, i5, and i3. The purpose is to reflect the new generation of software products centered on Internet applications."
