Microprocessor and Coprocessor

Microprocessor

The processor used in microcomputer is referred to as Microprocessor. Today microprocessor used in microcomputer designed in a single chip and fits into a special socket on the motherboard. The most fundamental part of the the mothermoard is the microprocessor chip. In personal computers two types of microprocessors are useed. These are:

i) Inter Microprocessor

This microprocessor made by Intel Corporation is commonly used in microcomputers. You can say that 90% microcomputers use this type of microprocessor. Actually the Microsoft Windows operating system is developed to run on Intel microprocessor. Inel company has marketed its microprocessors under the names Pentium, Pentium Pro, Pentium II (P2), Pentium III (P3), Pentium IV (P4), Core 2 Due (C2D) etc.

Today the most advanced microprocessor chip of Intel is C2D. Many ads for PCs contain the logo "Intel Inside" to show that the systems run an Intel microprocessor.

ii) Motorola Microprocessor

Motorola microprocessor is made by Motoroal. It is used in personal computers of Apple. Macintosh operating system is developed to run on Motoroal microprocessor.

Coprocessor

A coprocessor is a special additional processor chip that helps the processor of a computer in performing specific thasks. The math-coprocessor is an example of coprocessor. In modern computer math-coprocessor is specifically used to perform very large and complex mathematical calculations. The math-coprocessor is also known as floating-point cocoprocessor or numeric-coprocessor. The computers having cocoprocessors are used for engineering, scientific and graphic applications.
