Central processing unit

A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, 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), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers, and other components. Modern CPUs devote a lot of semiconductor area to caches and instruction-level parallelism to increase performance and to CPU modes to support operating systems and virtualization. Most modern CPUs are implemented on integrated circuit (IC) microprocessors, with one or more CPUs on a single IC chip. Microprocessor chips with multiple CPUs are called multi-core processors (MCP). The individual physical CPUs, called processor cores, can also be multithreaded to support CPU-level multithreading. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously called microcontrollers or systems on a chip (SoC).

• What is a Central Processing Unit? – Arm®

  The Central Processing Unit (CPU) is the primary component of a computer that acts as its “control center.” The CPU, also referred to as the “central” or “main” processor, is a complex set of electronic circuitry that runs the machine’s operating system and apps. The CPU interprets, processes and executes instructions, most often from the hardware and software programs running on the device. [...] The CPU performs arithmetic, logic, and other operations to transform data input into more usable information output. While the CPU must contain at least one processing core, many contain multiple cores. A server with two hexa-core CPUs, for example, will have a total of 12 processors.

[...] While the complexity, size, construction and general form of CPUs have changed enormously since 1950, the basic design and function has not changed much at all. Almost all common CPUs today can be very accurately described as von Neumann stored-program machines. As Moore's law no longer holds, concerns have arisen about the limits of integrated circuit transistor technology. Extreme miniaturization of electronic gates is causing the effects of phenomena like electromigration and subthreshold

• Types of central processing units (CPUs) - IBM

  CPU types are designated according to the kind of chip that they use for processing data. There’s a wide variety of processors and microprocessors available, with new powerhouse processors always in development. The processing power CPUs provide enables computers to engage in multitasking activities. Before discussing the types of CPUs available, we should clarify some basic terms that are essential to our understanding of CPU types. Industry newsletter [...] Core: Cores act as the processor within the processor. Cores are processing units that read and carry out various program instructions. Processors are classified according to how many cores are embedded into them. CPUs with multiple cores can process instructions considerably faster than single-core processors. (Note: The term “Intel® Core™” is used commercially to market Intel’s product line of multi-core CPUs.) [...] Quad-core processor: A quad-core processor is a multi-core processor that has four microprocessors functioning independently. Octa-core: An octa-core processor is a multi-core processor that has eight microprocessors functioning independently. Deca-core processor: A deca-core processor is an integrated circuit that has 10 cores on one die or per package.

• CPU Cores Explained: How Many Do You Need? | HP® Tech Takes

  A CPU (Central Processing Unit) core is the processor within your computer that executes instructions and processes data. It’s essentially the “brain” of your computer. Each core can handle its own tasks and process information independently. ### What Do Cores Do in a CPU? CPU cores are responsible for: 1. Executing program instructions 2. Performing calculations 3. Managing data flow 4. Coordinating with other components [...] A quad-core processor has four processing units, allowing for better performance in multi-threaded applications and enabling the handling of multiple tasks simultaneously. ### 6-8 Cores Ideal for: Serious gaming Professional video editing 3D rendering Running virtual machines In this core range, Intel CPUs often excel in single-threaded applications like games, while AMD CPUs may offer better value for multi-threaded tasks. ### 10+ Cores Best for: [...] Remember, the ideal number of cores depends on your typical tasks. For most users, a 4-6 core processor will provide excellent performance. However, if you’re into high-end gaming, content creation, or running demanding applications, considering a processor with more cores could be beneficial. Whether you’re looking for a new HP laptop, gaming PC, or desktop PC, understanding CPU cores will help you make an informed decision and ensure you get the performance you need. ## About the Author

• What is a Central Processing Unit (CPU)? - IBM

  A CPU is, essentially, the active brain of the computer. The CPU is the invisible manager inside the computer where data input is transformed into information output. It stores and executes program instructions through its vast networks of circuitry. [...] If still unconvinced about how critically important CPUs are to computing, consider this: The CPU is the one part that’s found in every computer, regardless of that computer’s size or use. If you’re reading this on a smartphone or laptop or PC, you’re using a CPU at this very moment. [...] Quad-core processors: Quad-core processors contain four processing units within a single integrated circuit. All cores run simultaneously, quadrupling their performance rates. Multi-core processors: Multi-core processors are integrated circuits equipped with at least two processor cores, so they can deliver supreme performance while using less energy.
