One hundred and twenty-four
Streamlined, something that Cao Changjiu was intoxicated with n years ago, but it's a pity that not advanced things in this world can be popularized.
Cao has long dreamed of making the streamlined architecture popular, shipping tens of millions of pieces every year, and the price is comparable to that of cabbage. It's just that this can only be a dream, no matter what noble things are mixed with interests, they will become tasteless, and brothers are not exempt from vulgarity, let alone shopping malls.
When the RISC chip architecture first came out, there were two companies working on it, Berkeley's RISC project and Stanford's MIPS project, which were developed in the 80s. What is rare is that both projects are scientific research experiments, and the results obtained are public, and anyone can use these two technologies for a certain fee.
Needless to say, MIPS is a widely circulated architecture that focuses on solving the problem of no interlocking in the pipeline, which has influenced the design of many processors.
As for Berkeley's RISC, no one may know, but when it comes to Sun, everyone knows that Sun's SPARC processor is Berkeley's RISC architecture.
These streamlined architectures are all high-efficiency and low-energy products, and can be said to be the best choice. It's just that fate is so funny, IBM is so talented, but it doesn't see these excellent processors.
In the late 80s, in order to develop its own operating system, the country also specially introduced the copyright of UNIX, and concentrated domestic researchers to develop their own UNIX. It's just that there is a lack of funds, and secondly, this thing is not mainstream, and even foreigners haven't done it, so it's not enough.
It's just that the slogan was shouted at that time, and Cao Changjiu was also enthusiastic, and he studied it for a while, and the blow can be imagined. The Risc architecture is really good, but any chip cannot be separated from reality, and without the support of the vast market, it is impossible to reduce the price of any processor.
At that time, the RISC architecture was pinned on high hopes, but unfortunately it was oppressed by the CISC architecture advocated by Intel, and could only succumb to the high-end market, with an annual output of less than one million.
You know, processors, like traditional prints, must rely on batch to win. It's all about making a mold copy.
Intel took the lead, and then IBM's east wind became orthodox. Although the performance is not good, it is worry-free, and it is not a problem to sell millions of dollars every year.
But RISC is different, the new architecture has to open up the market, someone has to write software for it, and someone has to pay for it, selling a million a year is already a great achievement, and you still expect it to reduce the price of this output?
Therefore, Cao Jiujiu used to drool over these machines, and he didn't even have the idea of owning them, just hoping to touch them. As for the computers I use, they are all old Celeron, as long as I can type.
In the microprocessor market, it is really impossible to give up at all, and the RISC camp has its own infighting, which gives Intel a chance to breathe, and after a few years of hard work, it analyzes the advantages of RISC and adds it to its own design, which is the famous 486.
In fact, these architectural techniques are all common, all follow the Neumann structure, and what changes is only the design concept. CISC is adding instructions for easier programming, while RISC simplifies hardware for greater operational efficiency.
The two have the same end in their development, and they are becoming more and more similar: most of the CISC processors have absorbed the essence of RISC, and their pipelines and single-cycle single-instruction operation methods are all original to the streamlined architecture, and they even only wear a CISC skin, and its internal structure is no different from RISC.
As for the RISC processor, it seems to be a bit of a departure from the original purpose of streamlining, with larger architectures and more and more instructions.
This is also the inevitable result of technological progress, what people pursue is the unity of performance and convenience, and each era has a different connotation.
It's just that Cao Changjiu, a half-man, is pursuing?
"This is the culmination of the effort of our research department, which completely overturns all previous ideas about microprocessors in the world, and is in the same vein as the 021 processor. ”
Cao Changjiu began to brag about B, and it was not too much trouble to fool the Germans anyway.
"The entire processor is a four-beat pipeline, with only 39 instructions, and the control part is small and efficient, with a total of 128 32-bit registers, which can be divided into 256 16-bit registers. In addition to the storage and fetching instructions, the other instructions are calculated between registers as much as possible, so as to avoid a large number of access to external memory, and the calculation speed is greatly improved. Due to the simple control part and few transistors, the power consumption is very low, especially suitable for those special occasions, such as portable computers. ”
Cao Chang was triumphant, and every feature he said caused a burst of exclamations from Hans, who seemed to see infinite application prospects.
When he heard that this processor had very low power consumption and could be used on a portable computer, Hans's eyes lit up.
"The idea of a portable computer is great, I met a Japanese guy on the plane, and I forgot the strange name, but it seems that he mentioned this thing and seems to be very interested. "It's strange that the Japanese like small things. ”
"Of course, that's what the devil does. Chang Chang smiled, "An island country has to save a little to feed so many people, hehe." ”
Hans nodded in agreement: "Sometimes I have to admire the industrial design of the Japanese, no matter what technology can be changed beyond recognition in less than three months in their hands, the thick can be made small, the big can be small." I know one thing, it seems that Philip invented a laser turntable player before, it was an epoch-making invention, and its sound quality is incomparably good, but the original model is too big, and the volume is two cubic meters. ”
I have known this for a long time, but Philip Air had this laser technology but could not apply it, so he was in a hurry.
"Did you work with Sony later?" said with a long laugh.
"Yes, Cao, you are really well-read and strong. Hans gave a thumbs up, "Philip's men found Sony and tackled it together." The Japanese were so amazing that they were able to shrink a machine with thousands of parts to just a few hundred parts, and then they jointly released the CD standard. ”
The crowd laughed, and Hans said, "I came from Europe the other day, and I met a Japanese man on the plane, who claimed to be from a Japanese company, and I don't know very well. However, he said that he made computers, and he purchased everything from software to hardware, and asked me if I had any information on laptops, and I thought we could cooperate in this regard. ”
Portable computers have been casually said for a long time, and the real first laptop computer was made by Compaq, and I don't know if it has come out now. However, the cooperation with Siemens will be very beneficial for the promotion of microprocessors in Europe.
"Well, we'll have to talk about cooperation. Chang Chang coughed lightly and glanced at Dr. Yu.
Dr. Yu understood, pulled Hans aside and whispered slowly.

I just came back today.,There's no code word status.,Make do with it first.,Update normally later.。 The PK was about to start in September, and I decided to join the shelves and ask the brothers to help, and this was the only chance to make money......
I forgot who I promised to push today, I really have the potential for Alzheimer's disease......
