Multiprocessing

Duo-core processors

What is Multiprocessing?

The use of more than one Central Processing Unit (CPU) with a single computer system, to perform tasks.

In multiprocessing most if not all CPUs perform the same function, however some may be reserved for a different function.

Advantages of using a multiprocessor

If one CPU fails, the other CPUs connected to the computer system can perform that CPU’s job

Tasks are carried out faster and more efficiently due to parallel processing among the CPUs

The user does not have to spend a long time performing one task.

Advantages cont’d

Large memory required for Duo-core processors facilitates the storage and processing of both processors

Disadvantages of using a multiprocessor

A complex operating system is required especially in Duo-core or Quad-core processors to manage two or more processes at the same time

It is expensive because the complex operating system is costly. Usually US$500.99

Large main memory is required which is also very expensive.

Examples cont’d

A person can be processing two Microsoft Word documents at the same time.

Also, a person may have large images to resize and therefore using multiprocessors to do the job

Multiprocessing

Example of a Multiprocessing System.

Duo-core Processors

It has an integrated circuit which contains two complete computer processors. They are identical and usually reside side by side on the same die (an unpackaged bare chip which houses the integrated circuit).

Examples

Examples of Duo-core processors are Intel Core2 Duo™

Examples cont’d

Example of Multiprocessing

For example, a user can be conducting a virus scan on the computer while watching a HD movie or playing a game while avoiding buffering.
