Rewriting the Technological Scenario

After Meng Qian ended his link, Fang Chen came to stand up to do more detailed interpretation. After all, Fang Chen is the person in charge of the company's computer business department. Meng Qian also understands but don't have to grab the "rice bowl", he Today is to grind the system platform for nearly four years.

The computer is white, it is four cores, computer hardware, operating system, system tools, and user applications.

Fang Chen first mentioned the hardware core, CUP, "Review the history of the computer, we will find an interesting phenomenon, with the rapid and more variables of the integrated circuit technology, hardware engineers have to continue to increase the instructions that can achieve complex functions and more A flexible addressing method, resulting in hardware increasing complex, costing is getting higher and higher.

In order to achieve complex operation, the microprocessor provides the programmer with a variety of registers and machine command functions, it is necessary to achieve its strong function by existing microprograms in the read-only memory, and the processor is analyzed. After an instruction, execute a series of primary instruction operations to complete the required features, this is the complex instruction set of Intel and Microsoft.

But we can see that now the number of instructions in complex instruction sets is at least 200 or more, some or more than 500, this road is true? "

Fang Chen showed some data on the big screen, "It turns out that increasingly complex and huge instruction systems are not only difficult to achieve, but also reduce system performance.

In a complex instruction set computer, the usage rate of various instructions is divided. We see from the above demo, 80% instructions used by a program arithmetic process account for only 20% of the processor instruction system, in fact, our daily The most frequently used instructions are taken, save and add these simplest instructions. In other words, the design of complex instruction systems is to design a processor that is rare in practice.

At the same time, the complex instruction system will inevitably bring the complexity of the structure, which not only increases design costs, but now it is difficult for the current process to do all hardware of the integrated instruction set on a chip, which will hinder the single piece. Development of computer.

There is also a problem, many complex instructions require extremely complex operations, which are mostly direct resemons for some advanced language, so universal. Since the secondary microcode is performed, the running speed of the simple instruction system that is frequently called.

From the hardware perspective, the complex command set is an unequal or long directive set, which must be split on the unequal length command, so there is a need for more processing when performing a single instruction.

That is why we want to choose a Power X chip. "

Fang Chen flipped the PPT, the screen appeared on the screen, in this gap, some people listened very focused people suddenly responded to a thing, wrong, how did Fang Chen go to interpret the chip? Is this not a computer conference? General computer launch will say what chip we use, this chip has more performances, and it is better to mention it.

But Fang Chen has a little fine for Power X, why? Yes, why? And why is this scene? Where did you show it?

Some people have slowly responded slowly. This is not the scene that Microsoft recommended Intel chips at the press conference!

In the computer conference of the Great Breeze Group, the advantages of IBM chips, the relationship between the wind group and IBM, and then I associate Intel Microsoft Alliance, many people began to realize what ...

"In contrast, POWER X executes the equal length JD command set, the CPU is faster and stable during the execution of the instruction. And from the long-term trend, the concrete command set is significantly better than the integrated instruction set in parallel processing. The streamlined instruction set can perform multiple instructions at the same time, which can be divided into several processes or threads, and are executed simultaneously with multiple processors.

After choosing such a CPU, let us take a look at the Kunlun system. "

There have been more contents about the Kunlun system on the big screen, and a contrast is made with the XP system. The Kunlun system is 32-bit systems simultaneously compatible with 16-bit applications. The system supports symmetrical multi-machine processing, which can be used on multi-architecture and platform. There is a function of storage protection, security control, and the Kunlun system is a time-time operating system, which is different from XP.

The next most important thing is that when I started the system, I have said that the system of the wind group is the Linux kernel. Since the Linux kernel is used, it will inevitably open one of the four major open source agreements. GPL protocol, so Kunlun does not open source?

Fang Chen introduced the road, "The Kunlun system uses semi-open source model."

What is a semi-open source mode, it is possible to understand that the mobile phone system can be understood, the Android system is an open box, everyone can see something in the box, can even go to the box to do some modifications, Apple system is a black box, you I can't open it, you can't see anything inside, but he placed a lot of interfaces outside the box and tells you how to connect through the interface with the box, you just follow the instructions.

The Kunlun system is a transparent box. You can see something inside, but you can't open, you can't go in, you can't modify it, I have a lot of interfaces outside, and because the box is transparent, development It will be more convenient for people.

In fact, Apple, which is still playing, but only the apple's box is still half translucent, can see some inside, but still understand.

The Great Breeze Group is playing the GPL protocol rules because there is a point in the rules of the GPL protocol, as long as it is not distributed, it is possible to open source.

That is, the Kunlun system is free, and can only be used on the computer of the wind group, you can't distribute the Kunlun system to other computers.

Introduction to the system tools, the system tool is the system itself is not brought by the system, but the system is related to the system, including system optimization, system management, etc., common system tools have drivers.

So this thing doesn't need to say more, Fang Chen briefly introduces the wind group and has designed a system tool.

Finally, I was approved. "I have already mentioned that we have a wealth of applications in Meng Gong, so how rich?

We have made a classification, including office software, social software, entertainment software, development software, anti-virus software, system tools, and other software.

In terms of office software, we have cooperated with Jinshan, have created a full set of office software, including hyacinth, Taobao Want Want, Yu Haiwei, etc., etc., can be used, in terms of entertainment software, Global game manufacturers in Kyushu platform have been successfully compatible with Kunlun systems, audio and video, and a variety of entertainment equipment such as NetEase players to meet everyone's daily entertainment needs.

All anti-virus software in China can be used on Kunlun systems. A variety of anti-virus software, including Kaspersky, including Kaspersky, also available, and a variety of browsers available.

As for the development tool, from the program to the image to edit the video editing, we have its own products, and the current market reputation is very good. Our style development tool has harvested more than 10 million development users worldwide. .

In order to further enrich the application, we will increase the cooperation with global software vendors, carrying the Kunlun Developer Community, which is convenient for software vendors to enter our system.

Finally, let's take a look at the price of the product.

SG6800 notebook main push configuration price: 11999

SG510 all-in-one main push configuration price: 9999. "

"Hey." The on-site applause was warm. In the case of a matter of public opinion, everyone will understand the importance and difficulties of public opinion, so you will be more excited.

On the next day after the Great Breeze Group's conference, IBM opened a press conference on the developer community.

At the press conference, IBM direct point named the reason why the complex instruction set is popular, that is because more than 70% of software vendors in the world are served for complex instructions, because Microsoft and Intel have already taken an ecology.

The streamlined command set will have to be compatible with the compiler, of course, the CPU will generate pressure.

But IBM said that the company will vigorously support the development of software vendors on streamlined instructions to provide sufficient tools, documents, and manual services.

IBM opened such a conference at this time, and some things were unclear, eating melon people, saying it, called WiBM Alliance Wintel Alliance.
