AI Activity Comparison
Arm
Arm Holdings plc is a British semiconductor and software design company that develops and licenses intellectual property, primarily for the architecture of central processing units (CPUs). The company's core business is centered on its energy-efficient reduced instruction set computing (RISC) architectures, which are used to build microprocessors for a vast majority of the world's smartphones, tablets, and embedded systems. A notable achievement is the development of the ARM architecture, a family of RISC instruction set architectures for computer processors. Arm licenses these designs to a wide range of semiconductor companies and partners rather than manufacturing chips itself. The company's recent focus includes the expansion of its architecture into new sectors, including data centers, automotive systems, and the Internet of Things (IoT).
