recent 25 years, computers have evolved from simple low-speed high-speed machines of large carnivores, and yet affordable. This is a quantum leap in performance was made possible with new technologies, some of which it was possible to use the computers themselves. Computers have greatly improved the basic information on parts Integrated Circuits (ICs) and the complex architecture of many microprocessors with millions of mini-components of them. Computer architecture is also developed with extensive new techniques such as pipelining and caching, which has evolved by itself. Development of performance information supported the integration of these technologies.

Reduced Instruction Set Computer (RISC)

Reduced Instruction Set Computer (RISC) processor design strategy is a very simplified instruction set than the traditional complex instruction set computer (CISC) is used. Philosophy of using the RISC CISC architecture was that it was not as fast and flexible to accommodate growth in the RISC.

RISC architecture had on many occasions, flexibility and speed when performing the same activities.

RISC processors in 1980 were very simple ones available currently available in the market. These processors only thousands of transistors and a typical instruction set was 32 steps. However, over time the number of transistors in the CPU as well as increased education. Previously, the processor register size is also limited to 8-bit, but as technology advances throughout the registers also increased at the same time allows performed fewer CPU cycles.

In addition, the instructions to perform more complex operations to software run faster than a complex task, which previously was done using a number of steps can now be carried out by one command. Today, many x86-based processors use a RISC like a good design. These processors are not only a large file (at least 32-bit) process, but also a wider memory bus (64-bit, compared to only 24-bits in 1980), which allows them to move more data and process at a time when your computer faster (Stokes, 2007) . There are also some other techniques are used to support the RISC, including pipelining and caching.
