Blooming America

"S has an unparalleled advantage over S. We at IBM should start from this aspect."

John Kirk is trying to persuade Watson Jr.

"Does S have any advantages over S?" Watson is still very generous in using money.

John Kirk, born in 1925, received a bachelor's degree in mechanical engineering from Duke University (ty) in 1946. After several years of practical work, he returned to his alma mater for graduate studies and obtained a doctorate in mathematics in 1956. After that, he entered IBM and became the technical leader of the 360 ​​mainframe.

And what he is doing now is to develop their own CPU for IBM.

The cooperation with Fairchild is fairly pleasant, but Fairchild has already started to cooperate with Motorola, so IBM must develop its own CPU to be free from control.

"How did Intel suppress the cost to such a low level?" John Kirk investigated this question for a long time.

Although IBM has the ability to produce CPUs, the technical reserves are sufficient, and even the copyright of the language can be bypassed in front of them.

But there is a problem-the cost of the chips produced by IBM is too high. This problem has always plagued IBM, and even Fairchild cannot compete with Intel in this regard.

Later, after investigating, they found that Intel actually built the factory in Taiwan, and the low labor cost and production cost kept the total cost to a minimum.

And there is another point, that is, Intel has a high rate of good products, because there are few waste products, so the cost is low. This advantage is unmatched by other companies. This is also easy to solve. After studying Intel’s CPU, they found that Intel actually abandoned the previous aluminum process, but used a copper process—in fact, the so-called micro process and nano process refer to The width of these aluminum or copper wires. Although there has been an increase in the production cost, the increase in the yield has caused the cost to fall.

In terms of production technology, the other party has already left IBM at a level, and IBM's research and development costs have always been known for being very high. Compared with the other party in terms of cost advantages, it is really not comparable.

Then, we must start from another aspect.

"After studying our system, I found that simple instructions, which account for only 20 of the total instructions, account for 80 of the program calls, while the complex instructions that account for 80 instructions have only 20 opportunities to be used. Because of this, We can get the S system by streamlining the commands."

The so-called S refers to a complex instruction set computer. The most classic Intel X86 series is the S system. The S system refers to a simplified instruction set computer, which is mainly used in servers and other equipment in the 21st century. The core of IBM in PS3 also uses S.

The number of instructions in an instruction system is limited by the number of bits of the instruction opcode. If the opcode is 8 bits, the number of instructions is at most 256. The width of the instruction is difficult to increase. Intel's solution is to expand the opcode. The operation code is followed by the address code, and some instructions do not use the address code or only use a small amount of the address code. Then, the opcode can be extended to these positions. If the opcode of an instruction system is 2 bits, there can be four different instructions: 00, 01, 10, and 11. Now that 11 is reserved and the opcode is extended to 4 digits, then there can be seven instructions 00, 01, 10, 1100, 1101, 1110, and 1111. Among them, the address codes of the four instructions 1100, 1101, 1110, and 1111 must be two less.

Because of this, when a computer with a complex instruction set is running, it needs a certain amount of resources to handle addressing and decoding. This is an advantage and a disadvantage.

"Computers using complex instruction systems have a strong ability to process high-level languages, which is beneficial to improve computer performance. But this is not absolute. With the development of the times, CPU speeds will become faster and faster. The complex instructions, variable instruction length, and a variety of addressing methods are characteristics, but in the future, this will become a hindrance. The time wasted due to decoding at that time has far exceeded the S The speed advantage that can be brought. At that time, S will be gradually eliminated, and S will become the mainstream."

Because the command is simple and direct, the efficiency of S will be higher.

"The prospects are very good, but in fact it is unlikely..." Watson smiled bitterly, "You should know something about the operating system developed by Microsoft, right?"

Cork hesitated, then nodded: "I've heard that this operating system is said to have increased our sales by 30."

"Yes, this is our questionnaire." Watson Jr. handed a document to the other party: "According to customer surveys, 80 of them said they hope that our next-generation computers will be compatible with Microsoft. Software."

Although the price of an operating system is 29,999 US dollars, people who buy it are still eager for it.

"They are generally dissatisfied with the efficiency of the 360 ​​mainframe, but their favorability for the software remains above 90."

Kirk already understood what Watson Jr. meant: "In other words...we have been kidnapped?"

Yes, in terms of mainframes, Microsoft's products have reached a level where ws dominates the world.

"Microsoft is a software company, and their operating system is just a platform, but with this platform, other Microsoft products can enter our mainframe..."

This is the most troublesome thing.

It is impossible for an operating system to monopolize so many markets, but through applications based on this operating system, this effect can be achieved.

IBM develops its own software?

Just kidding, IBM has never done anything like this, and even though IBM has developed its own products, Microsoft’s products have cultivated a certain degree of "loyalty" in the customer base. If the new generation of IBM mainframes If the S system is adopted, most of the previous things must be incompatible, and then...Orange will take advantage of it.

Although I don't quite understand why Catherine let the former Apple company be divided into the current orange and apple, but the other side's threat to herself still exists.

"So the best time for us to launch S is when the exhibition encounters a bottleneck, we can not only stabilize the market, but also counterattack the other side's market" Keke suddenly thought of a point at this time.

"Hmm..." Watson couldn't help nodding when he heard these words.

Indeed, when the architecture of S can no longer bring greater speed to the computer, then S can play.

"We can put it into Japan first."

After entering Japan, Watson found that this is a really good place, because there are no competitors, so there is no need to worry about anything.

Although some Japanese manufacturers have begun to launch a new generation of products, these Japanese are vulnerable to IBM's huge financial resources. History has advanced 30 years, but IBM is still relying on its powerful force to forcefully enter the market.

Compared to the United States, Japan is really a virgin land, and it could not be better to experiment with the new S mainframe. If the market responds well, it will be applied in the U.S. market for a long time. If the market responds poorly, then the loss will not be too great.

"The game is about to start..."

When she came to the venue in Los Angeles, Catherine looked at the busy workers and couldn't help but sigh.

"Well, it looks like there will be more people this year than in previous years." Although the game hasn't started yet, there are already a lot of people standing outside.

"Should be game enthusiasts?" These people should have come to see the venue.

"Probably..." Elsa glanced back at the venue that had been completed and was being set up.

After the game, it will become an electronic game center, and the first batch of 16-bit arcade machines will be listed here.

"Unfortunately, there are still many games that can't be played..." Catherine shook her head.

"We have the most advanced gaming equipment, can you play whatever you want?" Elsa didn't know what Catherine was referring to, and she didn't know anything about "CS" or "StarCraft"...

"The game I imagined is not like this." Catherine looked at the people on the street, and then made gestures: "Think about it, the picture of the game should be exactly the same as the reality, and it is best to have a full set of glasses. The azimuth super display...well, it also needs to have the ability to sense gestures, and the system can recognize every move..."

"Maybe it can be achieved in a hundred years?" Elsa also learned Catherine's complaints.

"Don't you think it's amazing?"

The most critical part seems to have not been noticed.

"It's really amazing~www.wuxiaspot.com~ but it's impossible to achieve it. It seems that the meaning of science fiction is stronger. In reality..."

Somewhat unlikely?

"But I think my vision is more likely to be realized first than those space programs of the US military."

According to Elsa, isn’t the Pentagon more sci-fi?

"Maybe it will happen in 2001..." Elsa suddenly thought of "2001 A Space Odyssey" that she had watched not long ago.

"Well... when I didn't say it."

(My idea is actually more practical, okay?)

I finished the exam yesterday... I don't know what to say...

To continue the exam tomorrow and the day after tomorrow, everyone bless me.......
