Detailed explanation-1: -ARM processors are a family of central processing units (CPUs) based on a reduced instruction set computer (RISC) architecture.
Detailed explanation-2: -An ARM processor is a Reduced Instruction Set Computer (RISC) processor. Complex Instruction Set Computer (CISC) processors, like the x86, have a rich instruction set capable of doing complex things with a single instruction.
Detailed explanation-3: -ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured for various environments.
Detailed explanation-4: -Having shorter and fewer instructions allows RISC processors to be highly power efficient. ARM is a closed-source ISA based on RISC that is licensed to companies for their processors and SoCs. The ARM ISA allows Arm to design high-performance RISC processors like Apple’s M1 chips.
