Recently,LoongsonThe 3A6000 series, which has 4 cores and 8 threads, was officially releasedDomestic CPU, which is basically the same as the function of Intel 10th generation Core 4-core i3, and is the strongest single-core performance at presentDomestic CPUFinish. Whileipc(performance per 1GHz) level, even capable of being the same as the 13th and 14th generation 4-core Cores, visible,LoongsonCPU design level, self-developed LoongarchInstruction setEfficiency, truly reached the world-class level.
However, with the launch of the 3A6000 series of CPUs, it is notLoongsonultimate. Their ultimate move is to be openInstruction set, IP licensing, and perpetual, free licensing. This is important for the wholeChinese chipsFor the industry, it is undoubtedly a major breakthrough and progress.
LoongsonFirst of all, it is 100% self-developed loongarchInstruction setOpen license, and is royalty-free. As long as the technology agreement is signed, the business can be granted a perpetual license to use it freely without any restrictions. This means,Loongsontechnology will be able to be used and developed by more businesses, driving the wholeChinese chipsThe development of the industry.
At the same time,LoongsonIt also allows outside businesses to communicate with them after proceedingInstruction setto develop customizations to suit their needsInstruction set。This open and free licensing method provides enterprises with more room for innovation and development, and can better meet market demand.
LoongsonIt also opens the authorization of three CPU cores, namely LA132, LA264, and LA364, corresponding to three performance levels: low, medium, and highEmbeddedcpu。As long as the business withLoongsonBy signing an agreement, you can use these directly for free and in perpetuityIP coresThere is no need to pay anything. LoongsonIt also said that they will also publicly license the more advanced LA464 and LA664 in the future.
This is related to:armThe way in which they are authorized is in stark contrast. armofInstruction setIP coresAuthorizations are all paid and expensive. withLoongsoncomparatively,armis obviously not as flexible and free. In addition, getarmAuthorized companies are not allowed to modify and expand, otherwise they will infringe. And in contrast,LoongsonThe authorization is more flexible and allows enterprises to modify and expand freely, which undoubtedly gives enterprises greater autonomy and competitive advantage.
In addition,armofIP coresIt needs advanced processes to support, such as 7nm, 5nm, etc. ButLoongsonofIP coresThe process requirements are low, taking 28nm as an example, it can also work normally. This is not the same as domesticChipsThe manufacturing level is compatible, so it is more suitable for the domestic market demand.
Well, whyLoongsonIt will be publicly licensedInstruction setwithIP coresWhat about it?It's actually quite simple. LoongsonI hope to be able to work together with other businesses to promote the wholeLoongsonEcological development.
LoongsonThe goal is to build one with x86armAn ecosystem that goes hand in hand. But the current gap is largerLoongsonIt is difficult for one company to promote the development of the entire ecosystem, because the development of hardware, software and other aspects requires the concerted efforts of multiple parties. Therefore,Loongsondecided to publicly authorize their ownInstruction setwithIP coresWe hope to attract other enterprises to join and develop togetherLoongsonEcology.
This open authority is open to othersChipsBusinesses are certainly attractive. After all,Loongsonof loongarchInstruction setIt can provide CPU cores with various levels of performance from low to high, which is suitable for the Internet of ThingsEmbedded, desktop, server, and other different fields. Currently,LoongsonThere are already successful examples of commercialization of these IPs. witharmIn contrast, the gap is mainly ecological. OnceLoongsonWith the development of the ecosystem, manufacturers can completely get rid of the rightarmThis is a rare opportunity. Especially inIndustrial control, Internet of Things,Embeddedand other fields, more acceptableLoongsonofInstruction setwithIP cores
As more and more businesses start using itLoongsonofInstruction setwithIP coresLoongsonThe ecosystem will become stronger. witharmThe competition will become more and more fierceChinese chipsEnterprises will gradually reduce the pairsarmof dependence, steeringLoongson。At present, there are more than 10 companies withLoongsonSignedLicense Agreement, makeLoongsonBecome China exceptarmis the only one that can provide a full hierarchyIP coresof companies.
To sum up, after years of hard work,LoongsonIt has embarked on a road of self-improvement of China's own CPU. By openingInstruction setwithIP coresAuthorization,LoongsonIt will attract more companies to joinLoongsonEcology, pushChinese chipsThe progress of the industry. In the future,LoongsonExpected witharmResist, realizeChinese chipsIndependent development of the industry.
