ARM Cortex-A
The ARM Cortex-A is a family of ARM architecture processor cores developed by Arm Holdings. Designed for application-level computing, Cortex-A cores are widely used in devices such as smartphones, tablets, laptops, and embedded systems. Cortex-A processors include both 32-bit and 64-bit designs. Most 32-bit cores implement the ARMv7-A architecture profile. All 64-bit Cortex-A cores implement the ARMv8-A profile, which supports both 64-bit and, in some cases, 32-bit execution. The Cortex-A series is distinct from Arm's Cortex-R and Cortex-M families, which are optimized for real-time and low-power applications, respectively. Unlike the other two families, the Cortex-A series supports a memory management unit (MMU) required by many modern operating systems. Overview Licensing and customization Arm Holdings does not produce or sell physical processors. Instead, it licenses its processor designs to other companies, which integrate them into custom chips.

Cortex-A32
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktops and servers, including Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used family of instruction set architectures. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
