Embedded systems have a dedicated function of a larger device, all main components are manufactured as single chip….

Definition: CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called a processor, the CPU is the brains of the computer where most calculations take place

Types: There are two primary manufacturers of computer microprocessors. Intel and Advanced Micro Devices (AMD) lead the market in terms of speed and quality. Intel’s desktop CPUs include Celeron, Pentium and Core. AMD’s desktop processors include Sempron, Athlon and Phenom. Intel makes Celeron M, Pentium M and Core mobile processors for notebooks. AMD makes mobile versions of its Sempron and Athlon, as well as the Turion mobile processor which comes in Ultra and Dual-Core versions. Both companies make both single-core and multi-core processors.

Function: A microprocessor is a silicon chip containing millions of microscopic transistors. This chip functions as the computer’s brain. It processes the instructions or operations contained within executable computer programs. Instead of taking instructions directly off of the hard drive, the processor takes its instructions from memory. This greatly increases the computer’s speed.

Size: When it comes to processors, size matters. Whether you’re buying a new computer or upgrading your old one, you must get the fastest processor you can afford. This is because the processor will become obsolete very quickly. Choosing a 3.6 GHz processor over a 2 GHz today can buy you several years of cheap computing time. Also check the speed of the front side bus (FSB) when purchasing your new computer or CPU. A front side bus of 800 MHz or greater is essential for fast processing speeds. The processor’s cache is also important. Make sure it has at least 1 MB of last level cache if your computing needs are average. If you’re an extreme gamer or if you run intensive graphics programs, get the processor with the largest cache that fits your budget. There can be hundreds of dollars’ difference between the cheapest processors and the most expensive ones. However, investing just a little extra cash can get you a much better processor.
