RISC and CISC Past and Present

Contemporary RISC architecture in the embedded market occupies absolute advantage, several years ago, RISC architecture completely defeated Pentium Pro, thus no free guide embedded architecture country. Currently there are three RISC architecture industry, they are ARM, PowerPC and MIPS. ARM is by far the industry's most popular embedded processors, their products throughout the various electronic tools and small consumer electronics products. You can turn your own pocket or bag. Casually pulled out from the inside of several electronic products, plastic casing and LCD screen inside, there will be at least one ARM-based embedded processors. For example, you carry a Blackberry Blackberry or beloved NDSL game, they are based on ARM processors.

For ARM, it has a very large group of partners and licensing provider. And then with regard Intel x86-based UMPC, MID and smart phones. However, many people in the industry think they like the successor to the Pentium Pro, SGI and DEC attempted to challenge such a gigantic company. But for RISC camp is now the world is not laughing. Today Intel has shrunk, it has all over the world, fab, detailed market positioning sectors, huge product line, Intel no longer be used as a joke, it has the ability to end the history of some of the products and vendors.

Atom processor, codenamed "Silverthorne", its goal is embedded RISC processor architecture with many competing vendors. Intel is the most wanted ARM and its huge market and its partners. Therefore, the following, let us look at this processor prelude to war.
