Evolution of Processors (CPU)

evolution of processor: Before telling you the evolution of processors, you should have brief knowledge on processor. The most important technological invention of recent times is that processor. The central processing unit (CPU) of computer is called processor. CPU works at the speed of an internal clock. The clock speed is called cycle and is defined as the number of pulses per second.

The average number of clock required for a microprocessor to execute an instruction is represented by cycle per second (CPI). Millions of instructions per second is the unit and corresponds to the processor frequency divided by the CPI.

Evolution of Processors

1) Complex Instructions Set Computer [CISC]

In this first processor maximum instruction were designed for the CPU. The reason behind this was to make easier to translate high level languages programs to machine languages. But this one was complex and expensive to produce.

2) Reduce Instruction Set computer [RISC] Processor

After practical use it was realized that many instruction supported by a CISC-based CPU are seldom used. Keeping this in mind the complexity of CPU was reduced by implementing the minimum basic set of instruction and set of instructions more frequently used.

The second important factor implemented was that length of all instruction make uniform, so that the decoding and execution of all instruction becomes simple and fast.

3) Explicitly

Parallel Instruction Computing (EPIC). The explicitly parallel instruction computing technology computing technology makes the software to communication clearly to the processor when operations can be done in parallel. To achieve this, it used tighter coupling between the compiler and processor. The processor based on this technology are powerful and simple.

4) Multi-core Processor

The multi-core processor handles more work because they work in parallel instruction computing technology makes the software to communicate clearly to the processor when operations can chip: Multi-core chips consume less and generate less heat that single core chip.

5) High End Processor

The processor of this category are designed for intensive applications, since the programs required high processing power. This category processors are used for statistical analysis, intensive graphics, creating and editing videos, multitasking and multi- threading applications, Both Intel and AMD introduced the high-end processor.

6) Mid-End Processor

These type of processors are used for middle intensive tasks. With this one you can do tasks such as 3D gaming, photo-editing, home video creating and multimedia application.

7) Economy Computer Processor

The processor of this category are low performing CPUs with less cost. This can performs the task such as office application, internet browsing, e-mail and common graphic etc., some of the common use economy computer processors are AMD Sempron, AMD-Athlon Neo and Intel Atom, Intel Atom and Intel Centrino.
