Loongson has 100 self-developed instruction sets, confident in the face of the US blockadeNetizens may also be worried
As we all know, among all the current domestic CPUs, Loongson is the only CPU with a 100% self-developed instruction set.
CPUs in other countries use ARM, such as Kunpeng and Feiteng;Some use x86, such as Haiguang and MegaCore;Shenwei uses alpha, although it extends the SW64 instruction set.
Previously, only Loongson used MIPS, but later it switched to the completely self-developed Loongarch instruction set, which no longer has anything to do with MIPS, and it can be said that it has completely gotten rid of its dependence on foreign instruction sets.
Many people say that now Loongson is no longer afraid of the United States, after all, the instruction set used is independently developed.
So,"Loongson"Is there really no need for the neck of the United States?Regarding this issue, many netizens said that in fact, Loongson is also afraid.
Why does Loongson use a 100% self-developed instruction set, and is still afraid of being caught by the United States?
According to Loongson's model, previous chip companies were similar to Intel, such as IDM, which was responsible for all aspects of chip design, manufacturing, packaging and testing.
But then TSMC creatively separated design, manufacturing, packaging, and testing, and many IC companies were no longer responsible for the entire process, but only a part of it.
For example, Longchip is just a chip design company and is not responsible for manufacturing, packaging, or testing, it just designs the chip and delivers the chip to the chip foundry for manufacturing.
Before Loongson, there were chips produced by STMicroelectronics, TSMC and SMIC.
Although in terms of design, Loongson is not afraid of the United States, but it should also pay attention to manufacturing, you must know that the current global chip manufacturing enterprises are inseparable from the United States' equipment and technology.
In order to improve the performance of chips, Loongson is currently taking two paths: one is to improve the level of architecture design, even if it does not improve the process level, it can also improve performance. The other way is to improve the process to improve the chip performance.
The current Loongson is 14 12 nanometers, this process has been inseparable from the United States equipment technology, etc., the next generation may be 7 nanometers, and the United States equipment technology is more inseparable.
So, do you say Loongson is worried about the strangulation of the United States?Of course, I'm worried, just like Huawei HiSilicon, although it can design a 5nm Kirin chip, or even a 3nm one, but the United States is stuck in its neck and can't find a chip foundry, so the chip design is just a castle in the air and cannot be manufactured.
Therefore, if our chips want not to be afraid of American necklaces, not only can they not rely on foreign sets of instructions in design, but they must also make progress in manufacturing and be independent, otherwise they will be like necklaces.
