What is arm?

What is arm? He is the name of an electronics company in the UK. His full name is Advanced RISC machine. Arm dared to be the first in the world. 12 years ago, It pioneered the chipless production model. That is, the company neither produces nor designs chips, but designs an efficient IP core and authorizes semiconductor companies to use it, semiconductor companies add their own design and launch chip products based on ARM technology. At last, OEM customers use these chips to build ARM-based system products. ARM products are IP core and have no physical hardware or software entities. At present, 103 giant IT companies around the world are using ARM technology, and 19 of the 20 largest semiconductor manufacturers are arm users, including Texas Instruments, Philips, and Intel. The only one of the top 20 giants who did not buy arm licenses was Intel's old rival AMD, while amd bought alchemy to compete with it, the MIPs structure is used (some broadband routers use MIPS processors, and Cisco routers also use this brand ). At present, there are market-oriented ARM7, arm9, ARM9E-S, Strongarm and arm10 series. Therefore, many OEM manufacturers are producing arm processors.
