With the 2,000 yuan price difference of the Jingdongfang monitor, the Huaguang computer set finally made a profit of 2,300 to 2,400 yuan.
In the future computer sales, Zhonghua Optical will be in an advantageous position.
Not to mention that there is still a profit of more than 2,000 now, didn’t Huaguang sell it with a profit of 300 or 400 at the beginning?
If you get impatient, just reduce the price by another 2,000. I don’t believe that I can’t defeat those foreign computer manufacturers.
Wanfeng has the advantage of being a local company. If there are any outstanding products in computer hardware, even if it cannot defeat foreigners, it will be able to fight with them for a while.
After Wang Desheng went back to organize the production of monitors, Wanfeng received more good news.
Cheng Gong's Huaguang No. 1 chip instruction set conversion is complete.
The original architectural design of Huaguang No. 1 had been completed, and Cheng Gong only needed to replace the instruction set he wrote himself with the X86 instruction set.
After Cheng Gong spent two months replacing the instruction set, as long as the tape-out was successful, this chip could be installed in Chinese computers.
At the same time, Cheng Gong also brought another piece of news. His subordinate Zhang Zhengyang had conducted detailed calculations on the Pentium chip and had indeed discovered a vulnerability in the Pentium chip.
The vulnerability is indeed in the division calculus.
The Pentium chip's flaw stems from the floating-point unit inside the chip. In a computer, all numbers must be expressed in binary. However, when the Pentium chip's floating-point unit expresses numbers in binary, errors in the calculation results may occur in some cases.
The result of the expression X-(XY)Y should be 0, but when -× is calculated using a Pentium processor, the result is not 0 but 256.
The impact of the Pentium processor on the accuracy of floating-point division instructions is related to the characteristic number of the input. In other words, there are some dangerous numbers that, if used as divisors, may reduce the accuracy of the quotient.
Zhang Zhengyang believes that at least 1,738 pairs of numbers will have errors when performing division operations, which reduces the reliability of computers using Pentium microprocessors. Moreover, this kind of error is not what Weiruan said that personal computers will encounter once in 27,000 years, but may occur once in more than 20 days.
As the saying goes, misfortunes never come singly, but Wan Feng encountered three good things in just two or three days.
Zhang Zhengyang and He Ming were the two people who followed Cheng Gong when he left Mi Guangnan's place.
These two people are usually very low-key. They have been in Huaguang for several years and are almost invisible.
If Zhang Zhengyang had not calculated the Pentium chip this time, Wan Feng would have almost lost interest in Cheng Gong having such a talent under his command.
"Engineer Zhang! Is your calculation correct? Are you sure this is a problem with the Pentium chip itself?"
"It's confirmed! He Ming and I have calculated this several times over the past month and are 100% certain that the Pentium chip has a vulnerability."
"Thank you for your hard work."
After Zhang Zhengyang left, Wan Feng began to think.
After thinking for more than ten minutes, he made the following decision.
First, he asked Cheng Gong to personally send the Huaguang No. 1 chip with the instruction set replaced to Shanghai Huaguang Electronics for tape-out, and notify Cheng Gong immediately after the tape-out.
Then he wrote a draft himself.
After finishing the manuscript, Wan Feng called Lin Lairong and read the manuscript to him word by word.
After Lin Lairong finished writing down the manuscript, he was a little dumbfounded: "Boss Wan! Are you saying this is true?"
"Our group's computer experts have been calculating for over a month and there's absolutely no problem."
"So what should I do?"
"Publish it to the Juhua Daily, and then find a way to get this information to the American media."
In the 1990s, Western media control was not so strict. At that time, the freedom of the press and speech they advocated were still more serious, unlike the media decades later, which became completely shameless and talked nonsense all day long.
"Okay! I'll do it right away."
The next day, the Xianggang Juhua Daily published an article on the front page about Intel's Pentium processor.
The article is as follows: As computers become increasingly important in our lives, their accuracy has become one of the most fundamental requirements for their existence. Because a computer calculation error can have immeasurable consequences, experts recently discovered that Intel's Pentium processor can produce data errors when handling division problems. For example, when a Pentium processor calculates -×, the result is not 0 but 256.
This is just one of the errors. After careful calculation, the scholar believes that at least 1,738 pairs of numbers will have errors when performing division operations, which makes the reliability of computers using Pentium microprocessors untrustworthy.
This is a very obvious vulnerability, and Intel programmers must have known about it. But what's unclear is why Intel released it, and why they concealed it, given such an obvious vulnerability. I hope Intel can give computer users an explanation.
The article is more than 300 words long, and explains everything clearly in just a few words.
As a window where the East and the West meet and one of the three major spy capitals in the world, any slight movement in Hunan and Hong Kong can spread to all parts of the world.
Six hours after the Juhua Daily published this news, a tabloid in the United States reprinted it, and it was soon followed up by several major newspapers.
As a result, news about Intel Pentium processors having huge problems appeared everywhere.
Intel has been quick to respond, accusing the news media and some consumers of exaggerating the Pentium microprocessor flaw. It claims the flaw has no significant impact on most business applications running on personal computers. Only a few workstation applications may sometimes experience a loss of precision in division operations.
They performed a trillion random division calculations, and the Pentium defect occurred with a rate of only one in nine billion, located in the fourth to the 19th digits of the result. The calculation error caused by the Pentium microprocessor defect would only occur once in 27,000 years for the average user.
Just one day after this statement appeared, the Hunan and Hong Kong newspaper that broke the news about the problem with the Pentium processor published another article saying that Intel's statement that ordinary users would only encounter it once every 27,000 years was a huge panic. The experts who discovered the vulnerability said that this cycle was not 27,000 years at all, and was less than 27 days. The exact time was once every 20 days, and they provided conclusive evidence.
Although Intel is still trying to argue, the market responded quickly. Stanford University issued a statement warning its customers not to buy computers equipped with Pentium processors.
The university's clients include companies listed by Fortune magazine as one of the 500 largest companies in the United States.
At the same time, IBM also decided to stop selling all computers equipped with Pentium microprocessors.
The occurrence of this incident completely disrupted Intel's development plan and business layout.
