What is RISC ?

Reduced instruction Set Computing

RISC collection orders is simplified, in fact, typical of the design of the CPU that is the basis for it, the simplification of the orders that lead to high yields and to accelerate the implementation of the orders. A processor that, based on this design can be built in to RISC (read risk) is called. The most important and the most popular architecture is based on RISC design. ARM. Just point the front of the risk, design the other with the name of the CISC there, which stands for Complex Instruction Set Computing, or the collection of orders is a complex architecture, x86, Intel, based on its design and processor desktop computers, laptops, and many other tools benefit from the.

the main idea of RISC, the first time by John cookie from IBM, and in 1974 was formed., the theory he noted was that a computer only from 20% of orders needs and 80%. orders unnecessary. Processors built based on the design of the orders a little support, so to the transistors, less also need, making it also low-cost. By reducing the number of transistors and the implementation of orders less, the processor in less time orders will process. A little later, the term RISC is a professor at the University of California to name David Paterson was created.

both the design of RISC and CISC to far in all sorts of tools are applied, but the general concept of RISC, in fact, a system in which the processing of orders, small and highly optimized will be discussed, just unlike CISC, where orders complex sent. One of the major differences between RISC and CISC is also in how to access the memory and store and run the information on it. In risk, access to memory only through the instructions, may lead to a significant do is, for example, not be part of the recipe add to memory access.

In addition to ARM companies much else, including Intel i860, AMD 29k, ARC, and etc., from the design of the RISC for the construction of the processor used., but, thanks to the expanding phone and tablet. ARM architecture as the most outstanding architecture is based on RISC known.
