Central processing unit The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations and a control unit that orchestrates the fetching (from memory) and execution of instructions by directing the coordinated operations of the ALU, registers and other components.
Haswell (microarchitecture) Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge microarchitecture.[1] Intel officially announced CPUs based on this microarchitecture on June 4, 2013 at Computex Taipei 2013,[2] while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum.[3] With Haswell, which uses a 22 nm process,[4] Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "Y" suffix.
