"It's really unpleasant to wear this kind of formal suit!" for a long time, he seemed to be uncomfortable, and kept arranging his collar and cuffs.

Although the custom-made Amani on the body is worth a lot of money, the silk fabric, the style is elegant and noble, and the black 'color' has a little metallic smell, but it is so incongruous when worn on the body for a long time.

"I'd love to hear someone say that men are meant to be restrained, and this dress is not suitable for a successful man like me. "For a long time, I felt as if I wasn't going to a banquet, and if I had a little more metallic smell on my clothes, I could wear it on stage and wave my guitar and roar.

"You said that the boy is not a man, this must be understood!" Zhang Yi glared for a long time, this guy was very angry at the dress she chose for the afternoon.

After eating the whites of his eyes, he didn't dare to move anymore for a long time, but he still muttered quietly: "I still like to be more relaxed." ”

Walking through the hallway, the two stepped into the hall. As soon as I entered, I was shocked by this momentum for a long time, the banquet hall was comparable to those palaces, it was extremely spacious, even if it could accommodate three or four hundred people, there was no problem, the design was also very reasonable, and the high roof provided enough volume without shrinking the area, so that so many people did not feel depressed when they gathered together.

The decoration of the hall cannot be described as luxurious, it is only the nouveau riche who like it, and perhaps the luxury can describe it in case. At that time, it was too late, and the oversized carved "flower" crystal chandelier on the sky "flower" board was opened, sprinkling a piece of light, and the handsome men and beautiful "women" old men and gentlemen on the scene were full of red light.

In the corner of the hall was a small band, and the soft music flowed from their hands. A grand piano was placed in front of them, and the style was still shining, and they wanted to come forward for a long time to see if the keys were ivory.

Two long tables were placed on both sides of the scene, and they were filled with 'fine' food for people to take for themselves, and some things had not even been seen for a long time. The waiters who shuttled back and forth were well-trained, and the goblets full of wine were placed on them without moving, which was quite surprising for a long time, and the idea that this was just a buffet party had already been put away.

The blonde and blue-eyed foreigners in the audience sat or stood there chatting, and from time to time they had to let out some low-pressure laughter, which made the little person who had grown up in the oriental cultural environment feel very uncomfortable, this kind of scene seemed to be far away from him, and it seemed that the more lively the scene, the more lonely he felt, and he couldn't help but grasp Zhang Yi's hand tighter.

Chang Chang was looking around, but Zhang Yi pulled away Chang Chang's hand and said, "I'll go talk to others, you can play here by yourself." ”

Chang Chang hurriedly said: "Don't, what should I do if you let me get lost alone?"

"You should just go to the park, no one will kidnap you, pull it with peace of mind, just see if there is a beautiful 'girl' who looks good and hooks up, haha." "Zhang Yi made an unusually rare grimace at Chang Chang, and his strange figure disappeared into the crowd in a flash, as if Ling 'Bo' was taking a slight step.

I didn't hold it for a long time, and I was gone to find someone again.

He was dumbfounded, there were all bunches of people here, and they were all small circles, and rashly 'dealing' with creatures was not a long-term strength.

After standing for about ten seconds, he had to start this embarrassing time for a long time, embarrassed to 'communicate' with others, he could only focus on other matters.

For example, the delicacies and wine in front of you are quite tempting for a long time. In such an environment where there is nothing else to do, I have been completely relaxed for a long time, and what research and development, what Microsoft, what IBM, are all not as good as this unknown small snack in front of me, which is really delicious.

The champagne was good, but it didn't match the taste, so he stopped the 'waiter' for a long time, took a glass and took a sip, frowned, looked around and no one paid attention, and put the glass in the corner of the table.

There are too many desserts, and I have been eating for a long time, and when I am bored, I smell a strong cigar smell, which suddenly arouses a long-term addiction to smoking.

I followed the taste to look for it, but I saw a benevolent brother swallowing clouds and spitting fog in the same corner, very happy, and I watched the long-term 'glamorous' envy of B.

I came out to change my clothes this time, my pocket was empty, and I felt bitter in my mouth, and it was nothing if there was no one in the hall to 'smoke', but once it was in my eyes, I couldn't help it, and walked up to talk.

It's still a bit of eloquence to talk about for a long time, limited to familiar people, and when you meet a stranger, it's over, and the clumsy tongue really makes that Taoist friend angry.

Finally understood the meaning of Changjiu, the Taoist friend smiled, pointed to a silver box on the table and said, "You don't need to look around, there is it." ”

After a long time, I couldn't help but scold myself for having bad eyes, it turned out that there was a neat row of cigarettes in the box, and it was specially prepared for the guests.

I lit one and took a deep breath, well, it feels good, although it is not a top grade, but it is also rare, this old and young are shrunk in this ventilated corner, which is more than a cigarette.

The 'spirit' spirit instantly soothed, and he exhaled a long puff of smoke, and then he had time to observe this fellow Daoist carefully. Brother Ren's face is bearded, and the 'flower' and 'flower' can't see the age in vain, quite the demeanor of middle-aged Sean Connery, and even the smoke is so manly.

The real man also couldn't help but praise secretly for a long time, "Didn't ask for the name of Gao?"

"John, you call me John. The old beautiful man smiled, wrinkles appeared at the corners of his eyes, "It's rare for young people to have such a big addiction to smoking, in order to live longer, you'd better exercise a lot and stay away from these toxic things." ”

"Cao Changjiu, it's an honor to meet you. I didn't dare to be rude for a long time, so I hurriedly reported my name, flicked the cigarette ash and said, "I have developed a bad habit for many years, and I have quit several times, but I found that I was sluggish at work and had no inspiration, just like suddenly changing from a supercomputer to the second generation of Apple, completely overwhelmed, haha." ”

John laughed and nodded again and again: "I'm worse than you, without this thing, I'm simply replaced by a cowherd star." ”

"Wait, Cao Changjiu, I seem to have heard of this name somewhere. John frowned and pondered, but the Chinese name was so awkward that he couldn't remember anything, "Don't remind me, I think for myself." You're also in the computer industry?"

"It's just a matter of buying and selling workstations. With a long smile, he secretly said that he has always been low-key, and he knows that there are really not many people.

As soon as John heard that Changjiu was selling workstations, he immediately became interested, so he chatted with Changjiu and talked about his work.

Listening to the boasting of this old beautiful man, he became more and more surprised and interested for a long time.

It turned out that the name of this brother, John Hennessy, was a professor at the Stanford Microelectronics Laboratory, and he was leading a group of students to do research on modern microprocessor architectures.

If others don't know the name of Mr. John, how can they not know him for a long time, this immortal is a grandmaster of modern computer processor architecture, the inventor of the famous MIPS system, and David Patterson of Berkeley.

It turns out that the concept of RISC took root as early as the time when Seymour Clay, the father of supercomputers, was a researcher, and its CDC6600 designed for the company is recognized as the origin of the 'lean' simplicity architecture, but it can only be understood conceptually.

Later, IBM inherited CDC6600's ideas, and in 76 years the 801 project led by Kirk of the Watson Research Center 'flowered' and produced a prototype, which is IBM's 'lean' architecture research and development plan, everything was caused by the classic 80/20 thesis.

However, IBM is not interested in this, its "essence" is attracted by the PC, so it was not until 90 years that the famous RS-6000 series was launched, and then it was jointly developed with Motorola and Apple to develop the poer series, and has held this banner until now.

But these studies did not come to fruition or were too late, and in the 80s it was actually two people who preached the RISC Bible: David Patterson of Berkeley and John Hennessy of Stanford, whose RISC and MIPS projects respectively successfully blossomed and became the leaders of the "Elite" Church, influencing a large number of followers in later generations.

Patterson's team was established earlier, and compared with Hennessy, Patterson is more enthusiastic about 'lean' and simple architecture, sparing no effort to promote the RISC architecture, and even its planned name is RISC, and the finished processor is also called RISC-I, RISC-II, and is finally called MrRisc.

Basically, on the West Coast of the United States, these two companies are working on the 'fine' simplified architecture, and in terms of time, Patterson's RISC plan is still earlier than the long-term chip molding, and the project was launched in 80, and the Risc-I processor was successfully made in 82.

RISC-I is a 32-bit processor, and the specific 'sex' can be regarded as the first in the world, nearly 3 times faster than Motorola's 68000, while the cost is far lower than 68000.

Patterson was an academic champion, and the technology he developed was not commercialized by himself, but the technology was passed down, and in 85 years, it was fully introduced and improved by Sun Company, and finally achieved the name of sparc, and its workstation products also abandoned Motorola's products and turned to Risc.

However, Patterson's technology can only be regarded as a school, they mainly use the register window *** technique, relying on the use of a large number of registers, minimize access to the main memory to improve the speed of operation, and its success is the introduction of a pipeline mechanism and branch delay to solve the problem of data waiting.

Hennessy, on the other hand, was a bit late, and the Stanford MIPS program he led took a different path. Patterson's research is successful, the pipeline technology makes the processor's computing speed greatly improved, but it also leaves a considerable amount of trouble, because as long as there is a pipeline there is a problem of interlocking, especially the hardware flow, this problem is also very serious, and the branch delay technology can only alleviate this 'problem', and does not help the speed in any way.

Therefore, Hennessy's research direction is how to solve this interlocking problem, and they put the solution on the compiler, using an exceptionally simple hardware architecture, combined with the compiler and other software technologies to achieve a complete RISC concept.

After a short period of time, Hennessy's MIPS project was successful, as the name suggests - a non-interlocking pipeline processing unit, which does not use complex hardware mechanisms to handle the pipeline part, but relies on the compiler to optimize the flow of combined instruction data, avoiding the headache of pipeline interlocking.

Although from the perspective of efficiency, the hardware pipeline seems to be more dominant, but its complexity is very high, take Patterson's processor as an example, its pipeline has reached the third order, the technology in the traditional field has reached its peak, and the dependence and interlocking problem of the pipeline is very serious.

Pipeline is an instruction execution technique used by all kinds of modern microprocessors, that is, the process of retrieving, decoding and executing several instructions is partially overlapped in the pipeline and executed at the same time.

The so-called interlock refers to the fact that the later instructions need the result of the previous instruction when the pipeline is running, and the previous instruction cannot provide the result in the operation, which often causes the pipeline to collapse.

Because the Stanford team was relatively late in research, they had a clear understanding of the problem encountered by Patterson, so they relied on a specially optimized compiler program to arrange and combine the code, and eliminate the interlocking instructions before they were sent to the pipeline for processing, which could naturally greatly improve the efficiency of the pipeline.

There is no martial arts in the martial arts, the more ancient the martial arts, the more powerful, on the contrary, the MIPS architecture is indeed superior to Patterson's RISC. However, it is undeniable that the development results of these two RISC processors have a considerable impact on the mature RISC system of later generations, and their 'refinement' has been incorporated into all modern processors, such as the long-term k32.

When he woke up from a deep memory, John Hennessy was still there talking, praising David Patterson's RISC-based processors and introducing his development plans to the long term.

Chang Chang smiled slightly: "Professor Hennessy, your plan is very attractive, when are you going to do it?"

Hennessy stopped at this time, and said a little uncomfortably: "No one wants to fund this project, everyone has seen David's achievements, but they didn't expect the flaws in it, I came here to try my luck and see if I can get sponsorship." ”

"That's a shame. He smiled and pulled out a business card, "It's so nice to meet you as an expert, if you need anything, you can contact me, I think we will have some common language." ”

Hennessy took the business card and looked at it carefully, with words in his mouth, and suddenly raised his head: "I remember, you are that Cao Changchang!"
