"HoPaho, I promised!"

"Really?hahaha

"Is it that funny?"

"Yes!" Shaking the phone with her right hand, Tang Jiayi's long eyelashes swept up and down, "There is really such a meeting, if you really decide to use the name of Shenlong CPU, how many years will you have to be complained about by netizens?"

"My fingers are on other people's hands, and I can't do anything about them. Everyone understands that I have a wife who has to be followed, hey, be careful!"

This time it was no longer the fruit on the table that flew as a weapon, and Atletico had just reached out to catch a lady's plush slipper when he found that his body involuntarily fell backwards, and the chair he was sitting on was kicked away by the opposite side.

However, the effect of force is mutual, the sling chair becomes a swaying swing pedal, and Tang Jiayi and the rattan chair under her also sway.

Her rattan chair and the hanging chair opposite are actually the same style, the alloy skeleton is wrapped with fine rattan to make an eggshell shape, hanging on the stand is a leisurely hanging chair, placed on the ground can also be swayed back and forth like a tumbler, left and right, more freedom and play than ordinary rocking chairs.

The two swinging and colliding balls fully proved to a certain lady that it is not dangerous to die, but a few heartbeats are inevitable. After such a fuss, Tang Jiayi suddenly restrained a lot, and waved her hand to beckon the board-type household robot that had just avoided to the side.

In fact, this product is a multi-layer trolley equipped with electric modules, communication modules, and sensor controllers, which can independently realize functions such as path finding, obstacle avoidance, recognition and execution of simple voice commands, and can barely be regarded as an intelligent robot. There are countless similar products in the horse house, and it is quite convenient to call them around, Mrs. Ma and a group of staff like to use them very much, even the four little ones have become commonplace with them, and as a result, when they go to other people's houses as guests, they also shout to the chair, "A little lower, I can't reach it", which is a little joke. Fortunately, cuteness is justice, and in the end, they helped their father sell a few sets of household robots.

In the fragrance of tea, Tang Jiayi poured herself a cup, put the teapot back in place and held the delicate painted porcelain cup in both hands.

After a long time, she suddenly looked up at Atletico Madrid: "You actually already knew that the national command set was no play, right?"

The end note changed, but it was because a yellow-green five-pointed star flew exactly into her mouth.

"That's right, add 10 points!"

Atletico Madrid pinched a processed star fruit in his left hand, grabbed the fruit knife with his right hand and flicked it upward, and a five-pointed star flew upwards and was sucked into his mouth and chewed and swallowed a few times: "Isn't this obvious?"

In his opinion, the "Shenlong Instruction Set" is completely invisible, and it is not his turn to come forward to propose the name, so he is naturally not afraid of causing complaints and embarrassment.

The two shared the star fruit, and Atletico Madrid cleaned up and pulled Tang Jiayi to sit down beside him.

The Ministry of Health says that smoking is harmful to health, and China Tobacco says that I can pay taxes to support the army; the Ministry of Health also says that smoking prolongs life expectancy, and China Tobacco says that I can promote farmers' income; the Ministry of Health also says that secondhand smoke is detrimental to family harmony, and China Tobacco says that you should go to the family planning office......

"Oh, pause, I'll record a video, go back and record it and help you post it on the Internet, which is guaranteed to make you popular again. ”

I mean there is a game competition between long-term interests and immediate benefits, and as a result, the in-laws have their own reasons for playing the needle, and in the end it is over. It is good to unify the instruction set to avoid internal friction, but the question is which one to choose? Which ones to give up? Scientific research units want to produce results and get grants, and enterprises want to produce products to make profits, and suddenly let them give up the platform they are used to and go to a new platform designated by the state, is there any compensation for this painful period?"

Actually, the instruction set (ISA) is not that complicated.

Instructions are the hardware programs that operate in the CPU circuit, the instruction set is a set of instructions that cooperate with each other, and the hardware implementation is the CPU with different frequencies. An experienced chip or operating system designer can design CPU instructions that look good, but it costs thousands of times more to put them into use.

First of all, it is necessary to modify the source code of the CPU circuit according to the new instructions to form a new IP core, repeatedly debug and confirm that it is correct in the auxiliary tools, and then contact the wafer factory to study and trial produce the new chip, and then the test is confirmed to meet the expectations before mass production, and then the mainstream operating system support must be completed.

This is not the end, and the next thing is to find a way to fool or pray for software manufacturers to use this instruction more, such as Intel and AMD in order to promote their own multimedia instruction sets, but there is no less flattery for game and audio-visual software manufacturers. These multimedia instruction sets complement the x86 instruction set, and if approved, will mean that the product will gain a greater competitive advantage.

In general, it is easy to design an instruction set, but it is very difficult to turn an instruction set into a CPU that can be used in real life, and it often takes a team of 100 people to invest more than a year. The preparation of lithography mask in the CPU manufacturing process is super expensive, resulting in a particularly large upfront investment in new processors, and can only rely on increasing sales to dilute the upfront costs.

It's so cumbersome to add new instructions, and it's even more difficult to get a new set of useful instructions from scratch.

In addition to the above work, it is necessary to build or transplant a complete set of auxiliary tools for development and testing, and also to attract wafer factories that are willing to cooperate with production, and to attract operating systems, application software, and third-party hardware manufacturers to support. As a result, the combination of software and hardware, the opening of the front and rear industrial chains, and the formation of a dynamic and strong enough ecosystem, can be regarded as a relatively successful processor architecture.

At the beginning, a reporter ran to ask ARM about his views on the national instruction set, and the executives calmly said that it is easy to build a new instruction set, but it is difficult to build an ecosystem!

Even the official institutions that were supposed to lead the country took a circuitous route, and state-owned companies cooperated with foreign capital to introduce ready-made products and put on vests, so as to quickly produce results and receive subsidies. As for this is the legendary three tricks of high-speed rail: opening the door to welcome guests, wielding a knife to relieve the cow, and having a different interpretation (introduction, digestion, absorption and innovation), or the son is not a cheating father, it is up to you to see your opinions.

The so-called not suffering from widowhood but suffering from unevenness, before the state-owned assets of Jiangsu and Shanghai took the lead, other national teams have followed up, and took out the domestic multi-core chip created by the ARM public version of the scheme to cheat subsidies, and even a certain Wei, who is known as the pride of private enterprises, also got a multi-core A57 Taishan server to make pocket money.

"Bee Heart didn't apply?"

"Someone suggested going, but I stopped it, and I didn't have enough confidence. ”

"What about the bee system?" she knew that the nuclear high-tech base had not only hardware, but also software and other scientific and technological projects, as long as it could reach one of the three "core, basic, and high-tech".

"Of course the system applied, in terms of scale and market share, we are the third in the world, although this third only does not even have a 5% market share. ”

"No, isn't this market share too small? Why do I think bee phones and tablets are quite common?"

"There are a lot of sales in China, about 10% of mobile phones, and one-third of tablets, but most of them are in schools, and the tablet rental plan has a lot of credit. ”

"Isn't this a good development, why step on two boats?"

"Of course, stepping on two boats is for fear of capsizing, don't pinch or pinch, let's just talk about things and don't extend it randomly!"

The left hand pressed the little hand twisted around the chest, "Don't move to show you a magic trick!

Tang Jiayi lowered her head as she said, but saw that there was a beautiful pink peach heart pattern on the bracelet, although it was limited to "pixels" and looked like a notched diamond, but it did not affect Tang Jiayi to make up its brain into a peach heart.

"You left a back door on the bracelet?"

"Can't you be a little bit more literary and fresh? Seeing such a beautiful peach heart, shouldn't you be moved to kiss first?"

"Why aren't you happy?"

"No, no," Atletico said again, reaching for his opponent's right wristband, this time much slower.

Tang Jiayi saw the other party's fingers tapping regularly on the metal shell, and asked, "Morse code?"

"Yes, an easter egg function, tap to enter Morse code to display text symbols and some emojis. The 501 is optimized for sensor control, and simple tasks such as this require no power at all, similar to a coprocessor. This is also the benefit of the new platform, which can be changed more freely. ”

Trying to knock nine times on the wrist, Tang Jiayi looked up at the flashing "SOS" code on it: "No! I remember you said that the biggest difference between ARM and MIPS is that it cannot be modified." Because MIPS is to engage in open licensing to allow third parties to add instructions at will, the result is that the ecology is broken into paste, and then ARM learns a lesson, whether it is Apple, Samsung, Qualcomm, or our bee heart, after spending tens of millions of dollars to get the instruction set authorization, they can only optimize the microcore inadmissible instructions. In this way, it will be much easier for third-party software vendors to do compatibility and adaptation, so there are so many cross-platform applications. ”

"yes. ”

"Ma cheap, you seem to be contradicting yourself, huh?" Tang Jiayi stretched out a finger and tapped her smooth forehead, "You said that MIPS failed in casually modifying and adding instructions, why do you want to mix it into RISK-V, which is more free and more casually modified?"

"Well, -V is actually a tiger skin, which makes it easier for us to get our own things. ”

The ecosphere is full of mysteries. For example, Loongson, the reason why it has been in the market for more than ten years is that in addition to the more serious technical blockade ten years ago, it is also a very important reason why they got up early in the morning but entered the wrong ecosystem. In 2000, there were not many open source instruction sets, but Nokia and Motorola mobile phones were inconspicuous, and they had to choose MIPS with a relatively good foundation.

According to Atletico Madrid's view, Loongson should actually be used as a game console, at that time, PS2/PSP also used MIPS architecture, and in-depth research on compatible chips is likely to reproduce the glory of Xiaobawang. It's a pity that Yangchun Baixue looks down on the Riba people, if this is not there. In recent years, Loongson's living environment has improved, on the one hand, with SMIC's mainland wafer factories, on the other hand, they have given up the unrealistic PC dream and turned to professional applications such as hardware firewalls.

In fact, don't talk about them, it's those giants who rashly kill another mature market, the king of Microsoft to do the mobile phone full of bags, the king of mobile chips ARM to do the server also has no income for a few years, and the only beep heart server can be used to cover up. The toothpaste factory entered the mobile processor market with low-power x86 processors, and also lost a lot, and the market share in exchange for billions of dollars in subsidies could not be converted into profits, and the loss was even worse.

Then everyone invariably remembered "Big Things Moving Clouds", no, it was "Big Things Moving Clouds". The mobile computing pattern has been decided, big data and cloud computing are almost the same, and the Internet of Things is still wild, so they have stepped in and launched their own IoT chips and systems.

Then the bees also mixed in, and the M5 bracelet equipped with the new architecture Bee Heart 501 is also a typical IoT application, representing a small temptation of the Bee and the RISK-V Foundation for the Internet of Things.

With Berkeley's appeal in Silicon Valley, the RISK-V architecture immediately attracted the attention and support of many universities and Silicon Valley companies, such as Google, Oracle, HP, Western Digital and other software and hardware giants, to jointly establish the RISK-V Foundation to promote its development.

This is also the reason why Atletico Madrid did not get a completely independent CPU, which is very cool, but the corresponding development and promotion costs have to be borne by one family, how can it be convenient and fast to follow?

And they're not afraid to get away with it, and the loose BSDL ensures that they can close their chip code at any time. But now is the time to find a way to get seed users, or it is more appealing to follow the big army.

Seed users are active early adopters who are able to bring in more friends and family, who are able to report bug submissions, and how they use a product largely determines the atmosphere in which the product is used, as well as the success or failure of a product.

The Berkeley and RISK-V labels have already helped the M5 gain a good following internationally, and by the time next month, Bee has released the M5 bracelet in the Forerunner version to them, and the first batch of premium seeds will be in hand.
