ARM is a good and very powerful company , ARM processor is the first RISC microprocessor designed by Acorn Ltd. in the United Kingdom with low power cost. The full name is Advanced RISC Machine. the ARM processor itself is a 32-bit design, but also comes with a 16-bit instruction set, which generally saves up to 35% over the equivalent 32-bit code, but retains all the advantages of a 32-bit system. Of course, the company doesn't make the product, it designs the architecture
The ARM architecture, once known as the Advanced RISC Machine or earlier as the Acorn RISC Machine, is a 32-bit RISC processor architecture. There are also derivatives based on ARM designs, notably Marvell's XScale architecture and Texas Instruments' OMAP family.The ARM family accounts for 75% of all 32-bit embedded processors, making it the most prevalent 32-bit architecture in the world. Of course it's not just 32-bit anymore.
ARM is one of the world's most influential chip technology providers, mainly engaged in low-cost, low-power, high-performance chip research and development, 99% of the world's smartphones and tablets use ARM architecture. All iPhones and iPads use ARM chips, and most Kindle readers and Android devices also use this architecture. How much better can Apple and Samsung be than Huawei at this point? And now it's actually safe to say that ARM is the world's only recognized standard-setter for cell phone chip architectures.
While ARM doesn't directly manufacture products, chips using the ARM architecture are ubiquitous. Smartphones, smart TVs, wearables, mobile base stations, enterprise servers, medical devices, smart driving, and other areas of technology such as the Internet of Things, ARM is involved.
