Central processing unit(Redirected from CPU) The central processing unit (CPU) is the part of a computer that interprets and carries out the instructions contained in the software. In most CPUs, this task is divided between a control unit that directs program flow and one or more execution units that perform operations on data. Almost always, a collection of registers is included to hold operands and intermediate results. The term CPU is often used vaguely to include other centrally important parts of a computer such as caches and input/output controllers, especially in computers with modern microprocessor chips that include several of these functions in one physical integrated circuit. A CPU Manufacturers and retailers of desktop computers often erroneously describe the computer case and its contents as the CPU which is misleading. A family of CPU designs is often referred to as a CPU architecture. Notable CPU architectures include:
