	Central processing unit
		CPU is the control center of the entire computer system.
		This unit is sometimes referred to as the microprocessor unit (MPU) in a microcomputer and the central processing unit (CPU) in larger computer systems.
		The CPU or MPU is composed of an arithmetic logic unit (ALU) and a control unit (CU).

	Central Processing Unit - MSN Encarta
		A CPU is generally a single microprocessor made from a wafer of semiconducting material, usually silicon, with millions of electrical components on its surface.
		On a higher level, the CPU is actually a number of interconnected processing units that are each responsible for one aspect of the CPU’s function.
		During this process, a unit called the program counter keeps track of each successive instruction to make sure that the program instructions are followed by the CPU in the correct order.

	Introduction to Computer Architecture - Central Processing Unit
		The Central Processing Unit - known otherwise as the CPU - is the nerve center of a computer.
		As the name suggests, the CPU processes information in a computer in the form of binary (0's and 1's) and converts it into instructions that tell the computer what to do.
		The CPU is a physical computer component and is not typically directly attached to the system board (formerly known as motherboard).

	Central processing unit: Definition and Links by Encyclopedian.com
		The central processing unit (or 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.
		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.

		In the preferred architecture of the CPU, the scratchpad 60 is a random access memory unit having 256 eight-bit registers.
		The control unit of the CPU can issue commands simultaneously to several controlled units, and a parallel bus architecture allows data to flow through several such units at the same time.
		The control unit has a read-only memory (ROM) with storage for, preferably, 256 micro control program instructions allowing for a macro instruction set of 68 commands which include a full range of arithmetic and logical operations.

	CPU - Plain English Definitions, Information, News, & Answers to CPU Frequently Asked Questions. (Site not responding. Last check: )
		A CPU, or a central processing unit, is a processor usually with one or more printed circuit boards and holds a chip called a microprocessor.
		One type is a ALU (arithmetic logic unit) for mathematical and logical purposes, while the other type is a control unit which deals with instructions from memory translates them and executes them.
		A central processing unit's performance can be enhanced with upgrades in ROM (read-only memory) or BIOS (Basic Input/Output System) and RAM (random-access memory.) Good quality microprocessors are found for cheap prices and ROM and RAM is also affordable, especially for home machines, such as desktop and laptop computers.

	Central Processing Unit (CPU)
		This Pentium CPU chip plugs into the ZIF (Zero Insertion Force) Socket and the CPU itself is secured usually with a tension bar lever on the side of the ZIF socket.
		In the early days of computers, the central processing unit was the area of the computer where logical and mathematical computations were carried out.
		It is crucially important that your CPU is properly cooled, due to the high temperature and heat produced by the core voltage of the cpu internally.

	CPU: Central Processing Unit
		A central processing unit (CPU), also knonw as processor, refers to part of a computer that interprets and carries out, or processes, instructions and data contained in the software.
		But in general, the CPU consists of the control unit, the arithmetic and logic unit (ALU) and memory (registers, cache, RAM and ROM) as well as various temporary buffers and other logic.
		CPU is also known as central processor or microprocessor.

	Central Processing Unit
		The data it processes is obtained, via the system bus, from the main memory.
		It is worth noting here that the only operations that the CPU can carry out are simple arithmetic operations, comparisons between the result of a calculation and other values, and the selection of the next instruction for processing.
		At the time of writing, the CPU of a typical PC is capable of executing many tens of millions of instructions per second.

		The central display and storage unit should be installed in a dry and safe place with access to the telephone lines.
		If the distance between the wind sensor and the central unit is more than 20 meters we recommend using a weatherstation that communicates with its sensor by radio.
		The central unit does not necessarily have to have a sophisticated display with all kinds of display options unless you want people to see the readings e.g.

	Glossary of Terms
		Central Processing Unit (CPU) - The main part of the computer, its 'brain', consisting of the central memory, arithmetic logic unit and control unit.
		Anything needed by the CPU (instruction or data) is first placed here before it goes to its final destination (such as the accumulator, IR, PC or other registers).
		Also, anything in the CPU that is to be stored in main memory comes here first before being copied into the main memory at the location specified by the address containd in the MAR.

	Central processing unit - Patent 4430711
		1 is a block diagram illustrating the principal, functional components of a central processing unit employing the principles of the invention.
		Data is also passed to the unit 24 from the CPU bus 10 via a data register (latch) 30, while output data from the unit 24 is returned to the main bus 10 via the ALU output bus 32.
		In addition, when the unit 24 is required to execute logical shift operations (e.g., during fixed point binary multiplication and division) shift control information is transmitted between the MCU 54 and the unit 24 via the shift control lines 80.

		The central processing unit is a critical component of the overall operation of the DADS system, and is the driving mechanism of DADS that is responsible for the safe and proper operation of all the related components.
		The CPU then accesses the threshold wavelength’s voltage, and compares the input wavelength voltage to the threshold in order to determine if the reflected light is a white/yellow line or gray-scale road.
		When the CPU receives a gray-scale road color wavelength, the signal is processed, and the control signal from the CPU is removed from the 5-volt relay.

		Understanding the methods of processing data and the function of each of these units is helpful in attaining a clear understanding of the information processing environment.
		Data are usually transmitted one word at a time (although some systems transmit half a word or two words at a time) so that the data path must actually have one connection for each bit in the word; for example, a sixteen-bit word computer would have a data path sixteen bits wide.
		During the fetch cycle the next instruction to be processed is retrieved from the main ale and memory.

		Central Processing Unit itself consists of three main subsystems.
		The first one is Control Unit, the second is Registers, and the third is Arithmetic and Logic Unit(ALU).
		Based on the instruction, the control unit would either fetch the operand and or carry out arithmetic or logical operations on it, or store the result of such an operation into a specified memory location.

	Central Processing Unit (CPU)
		The CPU is composed of logic gates that accept input, process it and produce output.
		To reduce cost, CPU manufacturers would disable the math co-processor (as was done in the old x386 chips), or remove the special on-board high speed caching memory.
		The CPU is built using logic gates, and contains a small number of programs called 'microcode' built into the chip to perform certain basic processes (like reading data from the bus and writing to a device).
