The aRm architecture is the instruction set architecture developed by the British anet company for its own PC, but in the end, it was only more than ten years later that it showed its skills in the era of mobile Internet, completely stealing the limelight from Intel.

But in the field of PC processors, aRm has never achieved anything. Before Li Xuan's rebirth, the latest aRm15 wanted to get a piece of the pie in the PC and server fields, but he ran into a nose.

The reason for this is that Intel's influence in the PC field is deep-rooted, and the difference between aRm and the existing x86indos is obvious, and it is not compatible with existing software, and there is a lack of dedicated applications, which leads to the failure of aRm15. In fact, the aRm architecture has not kept up with the progress of Intel's x86 architecture from the beginning. By the time it finally closed the technology gap between the two, Intel had already erected a thick invisible barrier in the PC field, and the software compatibility problem alone was enough to discourage potential users.

Application developers aren't going to put a lot of effort into a new processor that lives or dies like Intel's x86 architecture, and users who want to adopt a new processor will have to endure a lack of software options.

Not just aRm, but all other RIsc (Reduced Instruction Set) architecture processors have never posed a real threat to Intel in the PC world. Intel's processors have never been technologically advanced, on the contrary, for a long time, every new CPU from Intel has been criticized by the industry as useless.

However, Intel has swept all competitors in the PC field by virtue of the advantage of forward compatibility, which eliminates the cost of software development from scratch, and relies on the cisc (complex instruction set) that is backward and inefficient among all the population and should be swept into the garbage heap of history. The RIsc architecture simply couldn't gain a foothold in the personal PC space, and ended up moving to the workstation and server space.

Although according to the original trajectory of history, using aRm and Intel's x86 to go head-to-head, the future is bleak. But Li Xuan didn't believe in this evil, because he understood the reason why aRm in his previous life couldn't gain a foothold in the PC field - time.

In Li Xuan's view, aRm is a typical representative of the wrong time, in Li Xuan's view, it is five years later than the time when he should have achieved it, and it has fallen behind when it has just come out. Moreover, the company's financial situation has been very poor, and the investment in research and development is very limited, which has created a vicious circle.

The backward technology makes the aRm processor unable to give anet a fundamental inability to expand R&D investment to catch up with Intel's x86 footsteps. As a result, aRm fell behind in the competition with x86, and never got the opportunity to stand on the same starting line and compete head-to-head.

In 199o, with funding from Apple and VLsI Technologies, aRm spun off from anet and founded the new company with a total of 12 employees. It wasn't until TI and Nokia joined the aRm camp that ARM's financial situation improved, and the company's headcount finally reached 50 in 1993.

However, technology research is a very fair field, and only when there is input will there be output. With just such a small number of people in ARM Technology, even if one person can be used as ten people, it is far less than Intel, which has thousands of researchers. Therefore, aRm later decisively turned to mobile communications and other fields, avoiding head-on competition with Intel.

When ARM Technology was alone in the mobile field, it was finally unwilling to continue to be in a corner of safety, and was determined to attack the PC field again, but this time he had to face not only technical competition, but also invisible market monopoly. In fact, Intel has always been ambitious in the mobile field, where aRm is its own. As a result, both sides failed miserably in their mutual explorations, and it was too difficult to gain a foothold in a field where the other side had formed a market monopoly.

Li Xuan is familiar with this history, so he realized the opportunity of aRm, an opportunity that was only available five years in advance. Before IBm's PC was put on the market, the hottest microcomputer in the computer field was undoubtedly Apple's app1e series, app1eI., app1e2 used mos65o2 processors, and Intel's 8o86 was not conspicuous.

IBM saw the rapid commercialization of microcomputers represented by Apple, which replaced a large number of IBm's medium-sized and mainframe markets, and the company's profits showed negative growth for the first time in 1979. So IBm executives decided to quickly launch a competitive microcomputer to regain the market, which led to IBmpnetbsp; The PC did not allow IBm to achieve hegemony in the personal computer era, but it achieved the inte1 alliance that influenced the fundamental pattern of the entire information technology era. There have been countless PC compatible machine manufacturers who hatefully told reporters that selling a computer can earn 1oo yuan, of which Intel took 7O yuan and Microsoft took 4O yuan. The mystery of this sentence is endlessly evocative.

But if aRm can strongly block IBm's PCs before the inte1 alliance is formed, the future is uncertain. Using 32-bit aRm2 and the same 32-bit 8o386 for pk, aRm2 is naturally far inferior. But if it is compared with the 16-bit 8o286, it is superior in computing performance, not to mention the 8o86 and the castrated version of 8o88.

Of course, the real market competition is by no means a simple stacking of numbers, the aRm architecture designed by RIsc has simple and practical advantages compared with the x86 architecture designed by cIsc, but it is not without disadvantages. For example, RIsc architecture processors have higher requirements for memory capacity due to their fast computing power.

But this is already the best plan that Li Xuan can think of to fight against Intel, the future giant, and the rebirth aura is not omnipotent, and there is no way for him to conjure up a new processor comparable to x86 out of thin air. As for letting him do his own research, he really didn't have the confidence.

In his previous life, he was just an ordinary member of countless engineers in Silicon Valley, far from being a technical expert in the research ability group. There are only a few instruction set architectures that are familiar in his previous life, among which the aRm architecture is undoubtedly the most familiar to Li Xuan, and he knows more about aRm than his girlfriend's body. This is also where Li Xuan's decision to get aRm out in advance is the confidence.

Taking 10,000 steps back, it's not a big deal that aRm will continue to repeat the mistakes of its previous life even in the competition with x86. Li Xuan grasped aRm in his hands in advance, which is equivalent to grasping the future era of mobile communication in his hands, and at least there is a way out.

The full name of aRm is called anete (Aikang (company) reduced instruction set qì), and since Li Xuan has decided to attack it in this life, its name will naturally be changed to eastRIsnete (东 (company) reduced instruction set qì), which is referred to as eRm.

The eRm processor research group is naturally the most important topic in the semiconductor laboratory, and it is a priority to meet the needs of funds, equipment, personnel, and venues. Although Professor Zhao Weiming is the general leader of the research group, Li Xuan is actually the real command brain.

Initially, Zhao Weiming just regarded Li Xuan as a promising student, but with the contact and familiarity between the two, Li Xuan did not deliberately hide his strength. The whimsical ideas he kept putting forward were shocking the first time, and then they became numb after many times, and Zhao Weiming had already seen it.

He just felt that he had really lived on a pig in the past so many years? Fortunately, most people who were engaged in technology were relatively simple, and Zhao Weiming just regarded Li Xuan as a technological genius that he had not met in a century, after all, there were no such prodigies in the field of science and technology.
