Only when all numbers have been added is the result held in the accumulator written to main memory or to another, non-accumulator, CPU register.

By the early 2000s, CPU designers were thwarted from achieving higher performance from ILP techniques due to the growing disparity between CPU operating frequencies and main memory operating frequencies as well as escalating CPU power dissipation owing to more esoteric ILP techniques.

In the most commonly used computer architecture, the CPU consists of two main parts: Control Unit and Arithmetic Logic Unit ( ALU ).

On some processors the control unit may be further broken down into other units, such as a scheduling unit to handle scheduling and a retirement unit to deal with results coming from the pipeline ; It is the main function of CPU.

Computer systems generally consist of three main parts, the central processing unit ( CPU ) to process data, main memory to hold the data to be processed, and a variety of peripherals to communicate that data with the outside world.

An early computer might use a hand-wired CPU of vacuum tubes, a magnetic drum for main memory, and a punch tape and printer for reading and writing data.

In most traditional computer architectures, the CPU and main memory tend to be tightly coupled.

In modern systems the performance difference between the CPU and main memory has grown so great that increasing amounts of high-speed memory is built directly into the CPU, known as a cache.

The tasks share common processing resources, such as a CPU and main memory.

This is a canonical example of the PDP-1, with the console typewriter on the left, CPU and main control panel in the center, the Type 30 display on the right.

This polling can be done by a specialized processor in the device to prevent burdening the main CPU.

The main disadvantage of interpreting is a much slower speed of program execution compared to direct machine code execution on the host CPU.

* Power connectors, which receive electrical power from the computer power supply and distribute it to the CPU, chipset, main memory, and expansion cards.

Unlike USB, FireWire uses intelligent controllers that can manage their own transmission without attention from the main CPU.

The R2000 also had support for up to four co-processors, one of which was built into the main CPU and handled exceptions, traps and memory management, while the other three were left for other uses.

The main CPU recognizes " F-line " instructions ( with the four most significant opcode bits all one ), and uses special bus cycles to interact with a coprocessor to execute these instructions.

The first music synthesizer workstations from Ensoniq, the ESQ-1 as well as SQ-80, used one 68B09E as their main CPU.

The copper runs a program called the copper list in parallel with the main CPU.

An 8080 CPU loaded the microcode from an RM03, RM80, or RP06 disk or magnetic tape and then started the main processor.

An equally important reason was that main memories were quite slow ( a common type was ferrite core memory ); by using dense information packing, one could reduce the frequency with which the CPU had to access this slow resource.

Modern computers face similar limiting factors: main memories are slow compared to the CPU and the fast cache memories employed to overcome this are limited in size.

The main purpose of this system is to allow phone company technicians to identify which telephone line they are connected to.

Most radio studios are equipped with ISDN lines as their main form of communication with other studios or standard phone lines.

The main taxi stand on St. Kitts is in Basseterre, on The Circus, phone number 466 6999.

Each of the main network operators sells mobile phone services to the public.

The phone system was once one of the best in Africa, but now suffers from poor maintenance ; more than 100, 000 outstanding requests for connection despite an equally large number of installed but unused main lines.

As of March 2010, the telephone communications system was described by the CIA factbook as " seriously inadequate " with " the number of main lines is still deficient ", but with growing cell phone service and available email and internet.

Though its official name is Bureau Junction, the village is more commonly called Bureau, and Bureau is the main name used by phone companies, the federal Board on Geographic Names, and the United States Post Office.

From the user perspective the main difference between these systems was that Viditel used standard dial-in phone numbers where Videotex used premium-rate telephone numbers.

Internet is the main channel of e-service delivery while other classic channels ( e. g. telephone, call center, public kiosk, mobile phone, television ) are also considered.

The main differences in both equipments vary from the speed of signal, its length and its ability to overcome the noise of a phone line.

The main eight Shufflepuck players are standing in his way and will not let him get to the phone until he has beaten them all.

In this situation, his personal cell phone communications are considered out-of-band, relative to the main conversation method.

The main character, Phaethon, is a member of a group, called the Manorials, for whom telepresence has completely replaced the phone and video-phone, as the Manorials travel and communicate as virtual projections on the physical world.

* November 1: The main phone and Internet networks of the Palestinian territories sustained a hacker attack from multiple locations worldwide.

The main phone number is

* Polska Telefonia Cyfrowa, a Polish mobile phone network operator whose main brand is T-Mobile

Etisalat provided the equipment needed to restore the main mobile network of Libyana, the primary carrier in the country, to full capacity, and obtained a Tripoli-based database of phone numbers gives them information necessary to patch existing Libyana customers and phone numbers into their new system — which has been dubbed " Free Libyana.

They were connected by phone and teletypewriter lines to the main bunker at CFS Carp.

In the following episode, " Live Bait ", an Ericofon is the desk phone of Helmut Kellermann ( Anthony Zerbe ), the episode's main antagonist.

The main mobile phone provider is " Kyivstar ".

He is also the main playable character from the mobile phone game Mobile Suit Gundam SEED Phase-Act Delivery.

All telephone numbers are removed from the site's main pages after two months ( though still available on the site's forums ), to avoid another case like that of the Milwaukee bank teller, who received a threatening phone call from a man who had obtained her number from the website.

During a phone call to project director Yoshinori Kitase, it was suggested that at some point in the game, one of the main characters should die, and after much discussion as to whether it should be Barret or Aerith, the producers chose Aerith, as they felt Barret's death would be " too obvious.
